It means xpos-cmd was already used for something else.
Change all the xpos-cmd to something else like xpos-cmd-axis

Well if changing the voltage at the step pin from ~0V to ~5V
(by toggling the invert pin)  does not generate a step it really
looks like a wiring/GND/Disable issue of some kind.

EDIT: if there is a change in holding torque. This really indicates a problem
with power supply GND connections  or current set resistor wiring.
Is it possible your HV power GND connection is routed through your Arduino GND?
 

I have tried them and they seem good. It had inspired me to do some other work I've been meaning to get to.
I am working away with some longer hours so have not got as far as I'd like.
But I just pushed some work into master - with your changes.

That likely means that your latency has increased for some reason
Is the  xhc-whb04b-6 interfaced via a USB dongle or is it a WIFI device?

Any idea what would have caused this intermittent error message.

 

All that was added to my system was a WHB04B-4 wireless MPG.
The MPG works fine with no issues so far.

Thanks in advance. 

The voltage is approximately 43.7mv

The stepper has never moved connected to the 7i96s. With one of the hal files I tried there was a noticeable thump when powering on and the stepper had high holding power, like 40v. With the current config holding power is about 8v and is really not providing much in the way of holding or any real resistance.

With the Arduino test, the motor locked in position (full holding power) but I didn't measure voltage.

And is it 0V at the G250x when not inverted?
If so,  when you uninvert/invert the step pulse does the motor step?
 

The voltage flickers between 4.93v and 4.94v at the terminal block and 4.97v to the solder points on G250x

I would now check the signals at the G250X
to make sure you get a change from 0V
to 5V (measured from pin 28 to pin 30)
when you invert the step pin.

 

I am unsure about steptime; that is, steptime does not appear in my hal file. Is steptime also called steplen?

STEPGEN_MAXVEL = 25.0
STEPGEN_MAXACCEL = 25.0
DIRSETUP = 10000
DIRHOLD = 10000
STEPLEN = 5000
STEPSPACE = 5000
STEP_SCALE = 250.0

setp hm2_7i96s.0.stepgen.00.dirsetup [JOINT_0]DIRSETUP
setp hm2_7i96s.0.stepgen.00.dirhold [JOINT_0]DIRHOLD
setp hm2_7i96s.0.stepgen.00.steplen [JOINT_0]STEPLEN

setp hm2_7i96s.0.stepgen.00.control-type 1

setp hm2_7i96s.0.stepgen.00.maxvel [JOINT_0]STEPGEN_MAXVEL

I get 4.94v on TB1-3 when inverted. hm2_7i96s.0.stepgen.00.enable is true.

To test with the Arduino, I switched only the 3 wires, GND, STEP, and DIR, at the terminal block and pulled the power from 7i96s. So, the rest of the wiring should be fine.

Robot arms like kuka have a function that you can set an area (inside limit switches) where motion is prohibited for safety reasons for example for human interaction / loading-unloading etc.. Exists something similar to linuxcnc?

A MPG like equivalent would be:

Something more like this:

(which is a 100 PPR quadrature encoder with a nice knob)
 

si j'ai bien compris on peut utilisée une carte électronique (Arduino) a la quelle je branche un potar ,la carte enverra les signaux a la carte mesa.
