Hardware needed to switch from mach 3 6 axis to linuxcnc 9 axis

Category: General LinuxCNC Questions

Rick,

You'll find that there are many ways to accomplish the same thing in LCNC, but what I suggested was a combination of boards that would easily drive 9 separate axis motors, plus an analog 0-10v output for typical spindle control, plus a fair amount of inputs & outputs, plus has 5 high-speed encoder inputs since you mentioned 'closed loop.'

The 7i84 vs 7i84D - boards have the same I/O quantity, but one is for sourcing outputs and the other (D) is for sinking outputs.

The above recommendation is just that - a suggestion of an easy way to get 9 axes.  It was not a cost or space optimized solution, and I strongly discourage you from buying anything at this point.  You need to be in research mode right now.

If you want more specific recommendations, pics of the lathe, plus a detailed description of what additional 'stuff' you want to add would help us help you.  Pics of the existing control electronics (stepper drives, spindle drive, power supplies, etc.) and anything else (control panel) would help.

Make a list of all the inputs, outputs, axes, spindle, whatever.  Identify the voltages, amps, what components you have and will need in the future.

As for loading... are you talking about stock or part blank loading?  Does this hardware currently exist, or are you planning to fabricate some sort of automation mechanism?

Category: General LinuxCNC Questions

Some additional info would be helpful.

What is the machine? What is the upcoming project and why do you need three additional axes?
What are the current 6 axes, and what are the three additional axes you want/need to add? (linear axes, rotary, ballscrew, belt, worm drive, etc.)
When you ask for hardware suggestions, do you mean control hardware, motion hardware, or both?
What exactly is the current control setup?  What do you plan to re-use?
Closed loop how? Closed loop steppers, or closed loop back to the control (LCNC)?  Why do you think you might want this?
What IO do you need? Voltage, sinking/sourcing, current requirements?
Is there a spindle?  How is it controlled?

Anything you can provide details on will help.

Gravograph Engraving Machine(s) Conversion (Updated)

Category: Basic Configuration

Dear All,

Figured it out with extended reading - thanks for this great forum! - and a bit of creative try-and-error.
All 3 axes are set up and calibrated, homing works like a charm :)
Next and last open issue is the spindle - but I don't expect much difficulty with that. Otherwise there'll be another post here ...

ORIGINAL POST:
I've started a project to convert a 30-year-old engraving machine (Gravograph UNICA) to LinuxCNC running on a Raspberry PI 4 with a MESA 7C80. I have several Gravograph machines of various sizes available and am looking to roll out my conversion to most of them, if it works out as planned. These machines may be old, but as such they're solid and reliable. Also they are simple as there's just one stepper and one limit switch per axis and the spindle motor to control. The main reason for conversion is that the UNICA machine only runs on it's own Gravograph-unique operating system with a tiny monochrome CRT screen and propietary keyboard, with no communication port. The other, larger machines can communicate via serial port, but they also require Gravograph-only software ...

So far, I got the Raspberry PI, 7C80 and LinuxCNC up and running to the point that the x-axis stepper is operational by using linuxcnc.hal and linuxcnc.ini from this thread:
forum.linuxcnc.org/42-deutsch/52725-3-ac...esa-7c80-und-raspi-4

As far as I can tell, there's no wizard available (stepconf etc.) for configuring the MESA 7C80, so I need to work with the config files directly(?)

I modified linuxcnc.ini so that the stepper runs smoothly, and added three lines for the limit switch and homing. The stepper now starts running when I home the machine in LinuxCNC, and the program is apparently waiting for the limit switch to be triggered.
This is where I'm currently insecure and would like to ask for assistance:
  • What terminals to connect the limit switch to at the 7C80?
  • How to set it up as a NC contact (Switch opens when x-axis home position is reached)?
  • How to set up homing to move the spindle towards home at first if the home switch is not triggered, and then move a short distance away and back to the final home position? 

    This is my current linuxcnc.ini:

    Thank you for reading and thanks in advance for any answers!

help with millrun and/or custom Z-X-A(or C) lathe/machine

Category: Fusion 360

Hello everyone, hoping someone in the community can help. I have a lathe that I modified to have the headstock be driven by a positional stepper motor, and have added a spindle on the cross slide WITHOUT a Y axis. Thus, I am looking for help getting a working processor that can generate gcode for 2d milling in this configuration, meaning I can do things like drill holes on the face of my stock off center. 

What is the best way to go about doing this? Has anyone already made or used a working post processor for this? An old thread in fusion360 support said to find a post processor for millturn and remove mention of the Y axis so it only generates gcode without it - is that the right way to go about it?


Lastly, can someone verify if my kinematics are organized correctly in fusion360? My rotational/positional axis is along the Z axis and holds the stock, my spindle is on the cross slide (X axis) and points along the Z axis (attached image)

First of all thanks for the quick reply.

The setup with 7i97t with 7i84 would be ideal, however the 7i84 with sourcing outputs is currently out of stock everywhere I look. The spindle vfd takes a 0-10v signal and can therefore easily be controlled with one of the 6 axis outputs. I actually follow your Schaublin retrofit and that's where I got the idea for the 7i73 in my control cabinet. This can support physical keys in a matrix and also the encoders for Spindle/feed/jog so that's really good. I'm not satisfied with the cards in my electrical panel as well, but selecting from the available components this seems to work. Also, maybe in the future I'm gonna add a 4th axis to this machine and I'm not sure which type of motor I'm gonna use then, but having the 7i96 would leave the possibility of using a stepper or a servo for that.

Help with pncconf Z-X-A custom machine was created by ffffrf

Help with pncconf Z-X-A custom machine

Category: General LinuxCNC Questions

Hello, I am modifying a sherline lathe with a positional stepper to drive the spindle, and I will have a high speed spindle mounted to the cross slide. 

I am trying to set up this machine but am confused on how to handle the Y axis. For now, I WILL NOT have a Y axis, meaning any of my milling operations will be circular or tending to the spindle center line.

However, in PNCconf, it forces me to define a Y axis - do I have to do this? How can the kinematics be resolved if linuxcnc thinks there is a Y axis but it is not supposed to function. Is there any way to remove Y axis need from the machine?

My Z axis travels along the bed of the lathe to and from the spindle, my X axis travels side to side on the cross slide, and my A axis will be the positional stepper rotating the stock.

Summing Z axis on bridgeport

Category: General LinuxCNC Questions

Ok the last two posts are really useful additions & I'm moving along on this now finally although its been awhile (life issues...). I'm tired of cranking the knee manually. I'd like to modify my machine to implement gmouer's method.

I measured the torque to move the knee up and it takes 7nm on my machine with the table laden with the 4th axis spindle and a vice, so I'm going to use a 12nm closed loop stepper, and run it at 3:1 with a 72t htd5 pulley on the end of the knee screw and matching 24t htd pulley on the stepper, with a 133t belt between the two.
On the knee, I was investigating the physical side , and on my interact1 series1 there's a service hatch cover & window behind to enable you to get at the knee crank gear, which is perfect for both replacing the bevel gear which rotates the screw with a pulley, and also for a belt to come out the side of the knee to mount a stepper on there. I think if i unscrew the nut at the top through this, and lock & block up the knee in its highest position, I can crank the screw down enough to put the pulley on without disassembling it all. I will investigate taking the pedestal off and replace the knee elevation screw with a ballscrew.
I read some other comment about the knee on a series1 not being designed to move often etc, so I was surprised to see the machine automatic oiler manifold feeding oil to the knee leadscrew nut and z slideways so I think it could work as a full time axis without wear.

I have separate power controls for PC, MESA, Steppers & Spindle, if I'm going to be a away for a bit I just turn the Stepper & Spindle power off. And the way I have the relays that control the contactors if the mains goes & comes back on nothing energizes. To an outsider it may seem I have too many separate power supplies.

Please help me with my ground wiring for my sherline lathe - running into issues

Category: Turning

Hey everyone, I am having an issue where isolated analog output is failing to control my sherline spindle. This issue started after I added a spindle encoder. However, there are other issues going on that make me think there is a serious issue in my ground circuitry. I did a crappy job and there are probably lots of ground loops. Despite removing the encoder, I still get spindle control issues. As it stands, both axis work fine. At one point prior to encoder, everything worked fine.

What makes me suspect a (Dangerous) ground issue - is that moving around my isolated DC power brick (Which hooks into spin- and spin+ to get me my 0-10v range) can sometimes cause the spindle to turn on.

Currently, both axis work fine.

Therefore, I am planning on redoing my wiring, particularly when it comes to ground circuitry. I made a diagram of the new proposed ground circuit and wanted to see if anyone could verify this should work correctly.

My biggest question for this is: Does step- and dir- connect to GND on the steppergen of my 7i96s, or to the ground bar that connects to the sherline frame?

Category: Driver Boards

A 7I96S would do as it has the 0-10V VFD output  and 5 step/dir axis
and support MPG encoders. You might run out of inputs however.

What signal levels are the Z (Index) outputs?

Another possibility is a 7I95T but its likely overkill

 


Hi again, 
So, I attached some screenshots from the Delta servo manual a few posts above but don't know if they answer your question about the Z pulse signal levels.

Also, I tried to do an updated IO list below. Kinda worst case scenario for now, though. But given the list, which daughter card would you recommend?

Out
  • 4 axis, step/dir
  • 1 spindle via VFD 
    For mist coolant (fancy setup with a peristaltic pump):
  • 1 enable for the peristaltic pump (stepper with its own driver board with a range of speed settings)
  • 1 solenoid for air (I could run them on the same pin, I guess but it would be nice to also have the option of only running air) 

In
  • 1 4-axis MPG with axis select and increment knobs
  • 1 tool setter 
  • 1 probe 
  • 6 limit switches.I don’t know if these should be connected in series and what the impact would be, except for saving on pins. But I could also feed limit switches to the servo drivers and not the Mesa. 
  • 1 “home switch” for rotary homing together with Z pulse 
  • 4  Z pulse from the servo drives for homing (rotary axis at some point in the future) 
  • 3-4 Servo Enables (I can also program the servos to enable by default as the drives power on) 
  • 3-4 Servo Alarms (not sure it’s needed) 
  • 3-4 Servo Alarm Resets (not sure it’s needed) 
  • 3-4 Servo COMs (not sure it’s needed) 
  • 3-4 E-stop to servo drives (Not really needed but may be nice to have the drives stop the servos?)

Again, this is my first CNC, so I am not sure what’s prudent nor practical. Maybe it’s ok to run all limit switches in series and maybe the servo enables, alarms and resets, too? Also, no hard buttons at all on that list and I may have forgotten something. But it sure starts looking like some more IOs would be nice.

Hi all, 
Looong time lurker but finally signed up and first post here. 
Quick background, I've wanted a CNC mill/router for years and was intending to have a custom granite frame made and put on good, used hardware but a cast iron 3040 (cm) Chinese machine came up and I jumped on that. It came with a standalone, Chinese controller that I know I will have to ditch as I want a nicer GUI and also, it can't do probing. Finally, I am over my 'Linux is too hard for me' phase, so here I am:) 

Apologies if my lingo is off or I am missing some electronical know how, but I will do my best. 

Anyways, from reading a bunch of posts, I am leaning towards a 7i96s board but I am not sure of whether I need a daughterboard and if so, which one? E.g. I am not sure I can attach an MPG to the 7i96s? I recall someone mentioning that perhaps one of the step/dir banks could be used for it? 
Would it be ok if I do description of the machine below and maybe one of you can judge which daughterboard I'd need, if any?

4 Axis/ 4 Servos
Three axis, one servo on each but I see a rotary in my future, so let's call it four. 
I can set the Delta servos up to enable as soon as they boot (I hope that's not bad practice) so that saves a pin, each. But I would need to read, at least, the Z pulse for homing. Also, not sure what else is common without going overboard, maybe an alarm and alarm reset?

Spindle
I guess I will be running 0-10V to the VFD. (The VFD is also a Delta)

Limit Switches
The router will have Delta servos on it (came with steppers, but I have the servos already). It has cheap proximity limit switches on both ends of each axis and I intend to home the machine via the Z pulse of the servo. 

Mist Coolant
The machine will run mist only, no flood. Would be great to have this hooked up to the board. 

ATC
No ATC, none planned, either.

Pendent/MPG
I have a cheap one with the encoder wheel and two knobs (axis and increments) that I would like to use. But I could also get the wireless WHB04B-4 down the road. I guess that works with a USB dongle - so maybe it doesn't take up any IOs on the board...?

Tool Setter and Probe
I'd like to have a tool setter on the table and then also a probe.

I would love to just be able to give you a total of IO counts, but I am actually not sure how many the servos will eat up and honestly, I am sometimes still confused about what needs analog vs. dig signals. 

Anyhow, sorry for the long write up. If you made it this far, I am basically asking whether the 7i96s can run an MPG and if it has enough IOs or if I need a daughterboard and if so, which one would be a good one?

Appreciation to the Mesa board

Category: Driver Boards

Hey I'm so happy rite now I just have to show my appreciation for what I've got!  First off I want to thank PCW for being a genius and creating the Mesa board.  I also want to thank TommyLight for the inspiration to make a goal of fixing my machine.  It originally had a spindle issue and sucked at properly functioning as a PMW based VFD.  So replaced it with a T6 from StepperOnline threw it in the case and slapped a Mesa 7i96 to in and it fired rite up with no issues what so ever!  Anyways I'm so proud of this and want to let everyone at LinuxCNC know that I really appreciate all this!  

If there's anything I can do to help or contribute to the awesome CNC movement let me know.


Lol, a quick question.  How do I speed up the homing function on each axis?  Thanks

Getting started with 6i25+7i75+7i85s

Category: PnCConf Wizard

Dear gods, I've got the cards mentioned in the subject, and my purpose is to run a lathe with:
- STEP/DIR steppers for x and z axes
- quadrature linear encoders for x and z axes
- Argon servo drive to run the dc spindle motor
- a stepper, a solenoid and an absolute encoder for a tool carousel (although this one might be easier to control with a separate microcontroller?)
- relays for coolant and lubrication pumps

I've found that PncConf does not have the firmware option for my selection of cards, and now I have little clue as to how to proceed.
Why I'm in such a pickle is that I had a friend pick those boards for me, but later, he has become too busy to help me with setting them up.

So, I suppose my question is what should I do? Money or sunken costs are really not an issue. If I should buy new cards that are easier to setup, or pay someone to guide me, then I will.
Oh, and I do also have a 7i73, but no panel or pendant built or even planned yet, so I'm not so worried about that one. For now, I will be a happy man if I can just get the machine to run at all.

Updated linuxcnc 2.7 -> 2.9, now parallel port card not working with sherline

Category: General LinuxCNC Questions

So... I recently got a sherline lathe, and opted to download linuxcnc 2.7 to my dell optiplex 7010. I used a startech pcie to parallel port card and followed the instructions but kept getting errors, however, towards the end, I realized the computer did detect it via lspci -v, and set up stepconf with the lathe and got everything to work.

Now, I eventually plan to use a mesa ethernet board with the lathe so I thought in the meantime to upgrade to the newest linuxcnc version and set up the lathe the same way.

However, it is not working. In stepconf when I test my axis they work, but when I compile, the software no longer moves the axis. When I do sudo lspci -v I do see my parallel port at the address e010 just as i did on linux 2.7. However, when I open up linuxcnc and type in a g code like g01 Z5 F100, I get "no parport registered at e010 (or 0xe010)" and nothing happens. I do not always get "no parport registered at e010 (or 0xe010)" when I restart linuxcnc but regardless the axis do not move.

I am at a loss on what to do as this is the exact same hardware I have been using. I tried clicking on the sherline pins in stepconf as I think that inverts them but nothing has worked. 

In stepconf the axis works, and the steppers are energized. If I change the parport address to anything other than e010 or 0xe010, the axis no longer work in stepconf, so I know it is the right address
