sry for delay.

i have now the whole machine running with the original controller.

all works.. steppers,maindrive, all sensors and the spindleencoder.

in the next days i link up my raspberry pi 4 with a 7i92.
why the rasp? its easier for me instead a notebook.. i have the machine in my garage not in my basement...

if all works and linked to the mesa and is in my linuxcnc i came back.


parallel i would build a small model for the toolchanger to play in the apartment with the toolchanger carousel stuff.

thanks

At the end it was easier for me to compile a new bit file without the pwm/dir (I/O 07 PIN 17) and use it as a GPIO. It is working now.
Many thanks to you Peter!


Another question is about my "26 HDR" internal port of the 6i25 , I wanted to do my own encoder pcb but now I found a used 7I52S.
How to modify my vhd-file to do so and how should the cable from 26 HDR 6i25 to the 50 HDR 7I52S look like?
I don't now if I can use all functionality of the 7I52S but at least the 6 encoders and the rest filled with (stepper)outputs?
Should I open a new thread for this?

I made the config with PnCconf and only slightly changed to to account for probe basic interface.
the inductive endstops are mounted on the traveling part of the axis and there are metal stops at each end of the travel.

the machine has the following specs:
Machine Specs:
X460, Y750mm, Z160
20mm linear rails
10mm pitch ballscrews, 20mm diameter
Construction: aluminum profiles bolted to 12mm steel plates, welded gantry sides
Motors: Y-axis 6.8Nm stepper, Z + X-axis 3Nm stepper
Drives: DM556 V1 48v
Spindle: 24K RPM 2.2kW ER20
inductive endstops
good latency values mostly sub 3000ns servo

Hi,
I originally wanted to run a cheap DIY cnc machine using an old Intel Atom dualcore computer which has an LPT connector. But meanwhile I start thinking about higher quality components.

Same specs:
-stepper motors (already exist)
-linear rails for a work area of 1000/600/200mm (already exist)
-spindle Kress FME800 (already exists)
-stepper driver board with 5x Toshiba TB6560 (already exists)
-USB connected hand controller/job wheel LHB04 (already exists)

Now I wonder if I'd better go for an network/USB controlled Mesa card to get rid of that old Intel Atom computer and be able to use any machine (probably a modern notebook).

Also I would like to bux linear scales for my build, but couldn't figure out how they would be connected to LinuxCNC.
Is there a lis with reliable (but not too expensive) supportet linear scales?

And would you rather ust the Toshiba stepper driver board listet above or get some modern alternative?

Since I didn't really start building it, I'm free to change components for the good

I'm going to weld the frame for my machine. So I wonder what's the best way to start? At the moment I think I'm going to build z-axis first and depending on it's dimensions I can design the x-axis, then Y-axis.
But for designing the z-axis I need to know which linear scale system I need to mount and what size it is.

Since this CNC machine is intended to build electrical guitars, I don't require the highest precision, but I'd like to have as small tollerances as possilbe for a reliable pricetag.

Just getting started on planning my AXYZ cnc router retrofit. Regarding the “AXYZ AXI” stepper drivers, the wiring diagram I have indicates driver control is standard 3 cable (12vdc, step, dir). Dip switches have the micro steps set to 1200 micro steps/rev (default). Is there anything else I need to know?

The stock spindle inverter was replaced with an eTrac X2C and is currently wired with 6 wires (gnd, decelerate, accelerate,  5vdc, feedback, on/off). Is there anything else I should consider?

My current plan is to purchase a Mesa 7i96s. For a pc, I have a Dell Optiplex 7050 and an ELO touchscreen ready to go.

Backstory, the AMC controller board on the small AXYZ cnc router that I bought is bad. It shows ‘Error 92’ or no controller OS and the AXYZ tool path software is unable to communicate with the board to restore it. My plan had been to convert the machine to Linuxcnc anyways but it would have been nice to test it and take some measurements prior to starting the conversion.

Hi guys!
I get a VMC-100 as gift from a school.

I owm a F1P which i retrofit to LINUXCNC years ago. works perfect.
Same Machine as the VMC-100 but with manual Toolchange.

Now the VMC-100 has a carousel as Toolchanger.

 

This carousel have 4 proximity switch to operate the Toolchanger.

 

Sensor1 is a sensor to reference tool 1.
Sensor2 counts a hole in a parallel gear. is it counts 2 times the next toolslot is reached.
Sensor3 tells that the tool is engaged.
Sensor4 tells that the tool is disengaged and the mainspindle can rotate the carousel.

 

Main issue for me is that the carousel works above the Z reference sensor.
At Z reference positon the Carousel begins to disengage the tool and when sensor 4 is reached the carousel can rotate.

Does someone ever retrofit this in Linuxcnc and can share his experience?
I searched a bit arround but found only some videos with MACH3 and some dead threads.

I will use the orignial maindrive which has a encoder on it at the beginning.
the maindrive works with step/dir signals.

On my f1p was the same maindrive which i use to tap threads.. spindle orient is used for this but iswitch to a 1kw servo.
this time i will use everything orignial because i have 3 orignial stepperdrivers for the 5 phase steppers. later i would change to nema23 2 phase.
Main focus is to bring everything back to live without changing to different steppermotors or maindrive.

The maindrive is working and the encoder counts.
Steppers working.
all proximity sensors are working.


thanks for any help

Sure an automatic tool changer would be perfect, but that's up for in a later stage. For now I have a tool length sensor, that I would like to use with my collet spindle to get tool length set after a manual tool change.

When I run tcdemo.ngc:

- goes to change position
- when I hit "Tool change complete", goes to zmax, tool sensor x and y, starts going towards the sensor.
- As soon as the sensor is touched, I get "Probe tripped during non-probe move" and program is stopped

How can I get over this?

I attach the relevant files in zipped folder "toollength_problem.zip"

You might want to double-check that the

G38.x command is active before motion toward the sensor begins. Also, review your HAL and INI files to confirm the probe input isn't being tripped by noise or an early signal. Did you try adding a small delay before the probe move to stabilize the signal?

Hi all
After a couple of years, I am finally back and ready to making chips. I have a router, use steppers on parport. Linuxcnc is 2.9.4, debian:

Hi Everyone, 

I am new here and new to CNC, Linux and Mesa boards, so pls excuse the novice questions.

This is my setup
I have a 5-axis milling machine, which uses 2 stepper motors for the z axis, so in total there are 6 stepper motors. I have also bought a servo motor ECMA-C21020RS from Delta to power my spindle. I have a Mesa 7i96s card

Now for my question
Have I bought the wrong Mesa card for my requirement? From my understanding, the 7i96s can only control 5 motors so my 6 steppers and servo exceed the capacity. If so, what would be the best solution? To buy another card and scrap the 7i96 or is there an option to buy an add-on card to work with the 7i96s?

Thank you in advance for your help

Hello! First of all I’m sorry if this is placed in the wrong category. I’m pretty much new to Linux and LinuxCNC and been busy building a CNC mill but I’ve stumbled up on a lot of problems. 

My first thought was to get some help by using AI (Copilot) to configure Linux CNC but it doesn’t work that well because info online is limited on 2.9.4 so the AI is trying to use solutions that’s outdated for previous versions of LinuxCNC. 

The progress I’ve made so far is to configure and flash firmware to 7i95t with MesaCT and edit hall and ini files to run QTdragonHD and get the stepper motors to move but then I wanted do add 3 MPGs to jog each axis. 

Well that didn’t work that good.. these are the things I hope to accomplish one day: 

1. X-Y-Z MPGs with incremental and continuous movement. 
2. E-stop circuit (input) with reset. 
3. Add limit switches 
4.Closed loop feedback by using glass DRO scales. 
5.Spindle control 0-10v VFD or just relay control. 
6. Inputs/physical buttons: cycle start, cycle stop, 3 position resolution rotary switch for MPGs, 
7. Joystick (switches) to feed X and Y. (Like a power feed on  a manual machine) with a potentiometer to adjust feed rate) 
8. Output for fogbuster/flood coolant. 
9. Output for Compressed air nozzle. 

The list is long, 

I don’t know where to go from here.. 

Errors I’ve got earlier is missing motion.so and other modules, I’ll post the basic ini and hal files to.
 

Well, that never took off. Purchased a used PC with a parallel port breakout board and set everything up with what looked correct. Used a buck converter to power the board and noticed it wouldn’t change the voltage. Powercycled the steppers and breakout board and PC immediately turned off. Left the PC unplugged and the buck converter came to life at 26 volts, immediately blowing the caps in dramatic fashion. Well now with a fried PC and breakout board, I’d like just a ready made solution to power my lathe. I was going for Linuxcnc as I wanted spindle sync and backlash compensation, so if there are any great budget options that are just a ready made solution so I can stop worrying about wiring and flashing boards, that would be fantastic.

I am looking for recommendations to upgrade the control of an AXYZ cnc router, currently configured with AMC004 + flash card and an rs-485 usb interface. I’m a longtime Linux user but 1st time CNC router owner. The cnc machine has AXYZ AXI stepper drivers and a e-trac X2C inverter driving an Elite spindle.

I’ve been reading a lot but before I go ahead and order, can anyone confirm that the 7i96s is a suitable controller card? Are there any Canadian suppliers for these cards?

Any other advice before ai get started would be greatly appreciated!

Thanks for the info.

So the servo motors I'm looking at are integrated servo/driver/encoder and use stepper control signals. I'm under the impression that I would use a 7I95T card. Seeing as Y will have a slaved servo I'll be short one feedback channel. So I would get a 7I76 to plug in to the 7I95T correct? Then I will have all 7 feedback channels for the 4 servos and the 3 scales. It would also allow for future expansion of an A axis with feedback.

Now, If I go to run a spindle with encoder will that be handled by the 7I95T in addition to the 6 axis channels it has? Also, is this the only card I will need? It sounds like it runs ethernet to the PC and that is it.

I was checking your GITHUB repos - great content. I am actually working on ELS myself right now. Fitting mechanical parts first to the Atlas lathe - need to add spindle encoder and stepper tot the lead-screw.

What ELS do you use ? your own design? LinuxCNC based ?
