M19 for Indexing a Spindle using Stepper Motors

Category: General LinuxCNC Questions

www.linuxcnc.org/docs/html/gcode/m-code.html#mcode:m19

Says:

Spindle orientation requires a quadrature encoder with an index to sense the spindle shaft position and direction of rotation.

The need for an encoder can be worked around by using a StepGen with the index feature but that would still require
a once per turn signal for initial alignment.

M19 for Indexing a Spindle using Stepper Motors

Category: General LinuxCNC Questions

I am trying to use the M19 command:

m19 r90 q10 p1 $0

The m3 & m4 commands work as expected, but m19 does not.  Any guidance would be greatly appreciated.

My HAL and INI files are attached (Spindle0.inc renamed to be Spindle.inc.ini so that it could be attached).

These are the files.  The .INC files were renamed to be .INI so that they could be attached.

I've attached one spindle file:  that one and the one for Spindle1 all work exactly as expected.

I also attached only two of the axis files:  U & Y (due to the file limit).

Stepper Motor Speed does not match MaxVel was created by richcolvin

Stepper Motor Speed does not match MaxVel

Category: Basic Configuration

I am finding that
  1. the stepper motors for the two spindles work as expected, however
  2. the stepper motors for the axes (B, U, V, X, &, & Z) run at a VERY slow speed. 
The latency test on my Raspberry Pi 5 gave:
  • Servo Thread
    • Max Interval = 1,013,089nS
    • Max Jitter = 13,089nS
  • Base Thread
    • Max Interval = 46,407nS
    • Max Jitter = 24,074nS
I ran the Step Timing Calculator to set the BASE_PERIOD based on using StepperOnline DM542T drivers.
  • Step Length = 2.5µS
  • Step Space = 2.5µS
  • Direction Setup = 5µS
  • Direction Hold = 5µS
The recommended BASE_PERIOD = 26.57µS.

When I run LinuxCNC based on this configuration, the value for the parameter, hm2_yi92.0.stepgen.02.maxvel = 1.

Regardless, the stepper motor does NOT run at 1 rev / sec.

Attached are the HAL, INI, and include files for
  • Spindle0 (Spindle1 is the same)
  • Axis X (axes Y, Z, B, U, & V are the same)
The X Axis is set as Joint 0, Channel 02.

Help would be GREATLY appreciated!

Thank you and kind regards,
Rich

5-Axis CNC Setup with LinuxCNC + Mesa Boards was created by ozntyr

5-Axis CNC Setup with LinuxCNC + Mesa Boards

Category: General LinuxCNC Questions

Hi everyone,I’ve been working on a CNC project for a while and I’d like some advice before committing to hardware. Here’s my situation:
  • I originally built a 3-axis CNC router running on GRBL (ESP32) + a custom PCB. I used that setup for a long time and gained good experience with it.
  • Later, I decided to upgrade to 5-axis by adding A and C axes to the same GRBL-based system. While it functions, I quickly discovered a limitation: ESP32 GRBL doesn’t support TCP, so the machine can’t act as a proper 5-axis system.
  • Because of this, I started looking into LinuxCNC. At first I wanted to use my Raspberry Pi 5, but I read that the Pi version of LinuxCNC can’t really handle full 5-axis control.
  • I then tried installing LinuxCNC on an old laptop, but since it has no parallel port, I searched for hardware solutions that use Ethernet. That’s how I found Mesa boards.
From what I’ve gathered so far:
  • The 7i76 series supports 5 axes and spindle control, but its encoder inputs are only for the spindle, not for axes.
  • The 7i95 series seems more suitable because it supports encoder inputs for the axes as well. My thinking was that even though steppers usually work fine, it would be good to have encoder feedback to check for missed steps.
Where I’m at now:
  • When testing LinuxCNC setup, I couldn’t find any 7i95 options in PNCconf, which left me confused.
  • My current hardware: 2.2 Nm NEMA 23 steppers with DM556 drivers on all axes (6 motors total, since Y has dual rails).
  • I don’t have encoders yet, I was waiting to see which types are actually supported by the mesa boards.
  • As another option, I do have a couple of 400 W Delta B3 servos, but not enough to equip all axes. I’ve considered using them if steppers turn out too weak, but that would mean buying more servos.
  • My main goal with encoders is simply to check for missed steps on the steppers.
My questions to the community:
  1. Am I on the right track with the 7i95 + LinuxCNC setup for a 5-axis machine with encoder feedback?
  2. Would you recommend a different Mesa board or configuration for this?
  3. Are there any guides/resources for setting up a 4+ axis machine with Mesa boards and LinuxCNC?
Thanks in advance for any advice!Ozan T.

LCNC 2.9.5 - How to jog with a wireless xbox bt controller was created by phew

LCNC 2.9.5 - How to jog with a wireless xbox bt controller

Category: Basic Configuration

Hey,

I am trying to set up my xbox controller to jog a three axis machine (y-gantry). Using a bluetooth dongle I had to fiddle around a bit (and install xpadneo) to get the controller to connect to the system but I eventually got there and do see input when pressing buttons/moving the joysticks.

I was digging into LinuxCNC a few years ago but then life happened and I had to put the project on ice up until now. This is my first home-built CNC (wood router) and I am very new to all of this.

My goal is to be able to move the X, Y (gantry) and Z axis using the gaming controller when there is no gcode being executed.

Currently this is a parport setup and the stepper motors are not actually installed on ball screws so I do not mess up anything while testing. I am planning on switching to a mesa card in the near future.

However, joint.*.vel-cmd always stays 0 and obviously the stepper motors are not spinning. Also I am not sure what mode I have to use, but I also tried setting halui.mode.manual and halui.mode.teleop using the [Set] button in halshow, but this did not change anything.

Setting it up like this will not allow the machine to start when the Xbox Controller is not connected as it expects the controller to be found. The controller will shut itself off if not being used for a certain period of time and this will also result in an error popping up in axis ui.

I think my current approach is way more complicated and clumsy than it actually needs to be, but the learning curve seems to be pretty steep for me and therefore I probably resorted to using way more AI generated code than I should have.

How do I
  1. set this up correctly so the Xbox Controller input can actually controll the X, Y and Z axis?
  2. set this up in a way so the controller does not need to be connected in order for the machine to start and won't result in an error when the controller disconnects for some reason
Any help is appreciated!

Getting (hopefully) close to an Rtelligent build

Category: EtherCAT

I have made some big progress lately. I have the limit switches and homing switches working. I also have the E stop working.

My issue is the RS750E AC servos shake quite a bit. Without the drive belts installed, the servos will sit and shake after completing a move. With the drive belts on, the system moves in the correct direction, but does so in a shaky manner.

My hypothesis is too much integral gain. I believe the problem is because I started with the stepper motor examples. Maybe there are some PID gains inside the drive that I need to configure.

I think what I need are the drive gains set with the SDO parameters inside the XML file.

Thanks for all the help

replace x with your servo/spindle index

net s-vel-cmd <= spindle.0.speed-out
net s-vel-cmd => cia402.x.velocity-cmd

You will need csp mode 0 :

setp cia402.5.csp-mode 0
setp cia402.5.pos-scale 1

Hi again. I have sorted the power issue (manual was no help at all). Now, I have it set to Linuxcnc using ethercat. It is all communication etc. I want to run the servo as a spindle motor so just have the target-velocity (60FE). How do I create the 'pins' to tell the drive to turn at say 1000rpm with an M3 command is given. I have done the many times using a VFD (much easier but space and weight limits force me to use a servo).

I am soooo out of my depth here, any help is always hugely appreciated. (I have already looked through the various threads and found no help after hours of scrolling)

Omg it worked!!! Thank you so much PCW not only did you spoon feed me on how to get my 7i96s to run my spindle but you also helped me get all my steppers working with the BoB. Thank you so much

Hi, I am creating a custom machine for work and really really need help. I am using the above driver with a 1000w servo motor for the spindle. I have installed ethercat and configured. I have downloaded the xml file for the drive from stepperonline. I have created a hal file that loads lcec and the xml file. But when I start linuxcnc is stops with an error saying lcec exited. How can I use this to drive the spindle. I don't need limits or probes or anything, Just speed.

I am really out of my depth here as I normally use a 3ph and vfd but space and weight does not permit this on the machine I am making.

Thanks

Russell

ESP32 HAL2UDP setup for linux CNC noob.

Category: Computers and Hardware

Hello, I just started working on the linuxcnc esp32 W5500 setup and I ran into some issues.
1. Hardware: Rpi4 8gb with linuxcnc 2.8.4, W5500, Esp32 Wroom 
2. Esp firmware: hal2udp pwm
3. Motion: open loop stepper with TB6600 Driver

Issues
1. activation of spindle or flood no voltage change on esp32 pins 4 or 25.
2. joint follow error all axis3. My stepper is enable without the enable pin connection (I'm not even sure what pin to use for enable/disable on the esp32-the pin out from the read file doesn't show what pin to use.
3. udp.stepgen.1.enable (error doesn't exsist) (My assumption is that because the udp.comp file doesnt show the param or pin) maybe I'm missing something
4. is the Pid function only used for closed loop steppers to accurately determine movement
I attached my hal and ini files

thanks for the help

Axyz retrofit - spindle wiring 7i96

Category: CNC Machines

I think I have wrapped my head around my stepper motor and limit switch wiring. Regarding the spindle, I have a few questions:

The inverter is a woods eTrac x2c and the manual offers a nearly overwhelming number of options. I was never able to see the spindle working with the stock
AMC controller. I have attached the relevant table from the inverter manual and it seems like I should be able to use the analog spindle interface to provide 0-5vdc signal for speed control (vin). Do I simply use inputs on the 7i96 to conteol fwd/rev and a ground connected to the inverter common? Is that all there is to it?

The original wiring from the AMC controller to the inverter is somewhat different and it isn’t obvious that the AMC was actually able to control the spindle speed. It is connected to use 4 preset spindle speeds and the AMC has wires indicating an acceleration/deceleration signal, as well as some connections to NO and RCM.
