It look basically OK but I do not have information on the plasma source pinout

You probably don't need to compile the gtk_little_probe.py file.

Python is an interpreted language, so often you just need to make the edits and run the code.

So, the reason that "make" is not doing anything is that the file in question is not mentioned in the makefile, as it is simply interpreted as and when needed.

(There is a complication that Python code is compiled to bytecode (.pyc) and sometimes that might be run instead.)

To be sure that your edited file is running, maybe put a "print("this is version 2.2.2") near the top of the file?

G49, did you modify your tool setter macro? If not I would check that your var file and pb version are all correctly aligned and the parameters are storing in the var file.

Pots do not work with digital inputs, but encoders do, so given enough space the pots can be switched for encoders.
For rough analog, Mesa 7i77 has 4 analog inputs (in0-in3) when set in mode 2, you can try that and see if it is usable for you.
For outputs, 2.10 (or Master) has a nice feature where you can toggle inputs and outputs from the "show hal configuration" menu, so add the Mesa outputs by assigning some random names to pins, then use the above to toggle on and off outputs by clicking on SET or clear, as shown bellow:

I figured out how to setup homing mode in the ClearView software, and setup a home sensor, but I have no clue how to make it start homing when home is pressed in linuxcnc. I assume I need to do something with the joint.0.index-enable pin?

You can get acceleration by taking  the derivative of the encoder velocity pin with the HAL ddt component.

Sweet, so setting the following error higher allows it to run at higher speeds. What is the trade-off? Is it less accurate with a higher following error?

How do I know when to edit something in the .ini file vs the .hal file? it sounds like ferror is linked to a hal pin, but is configured in the .ini file..?

Then, regarding a completely different topic, I was wondering about the pros and cons of using the servo's built-in Homing mode. And if it makes sense to, how would I use HM to home, then switch to CSP for operation?

On the same topic of homing, how would I set that up? Is there a hal pin for homing that I would need to link to a homing sensor?

Hello, i have a project im working on (Not a CNC machine, but i believe a Mesa card is good capable hardware for this application) where im trying to determine the rate of acceleration of an externally driven spindle using an encoder. 

There doesn't seem to be any built in components for this that i can find.

The use case, is to feed the rate of acceleration into a PID loop to control the output of a stepper/servo that regulates the spindles speed.

Is there a relatively easy way to measure/determine rate of acceleration accurately?

thx i thought the light would be on, and flashing while communicate. i just connected them to the ek1100 and no faults

Interesting work you present here! I might get a chance to start implementing a tool changer over christmas/new year.

Hallo rodw
I hadn't installed THC until now . And have found that it is better if you use metallsheet with about 2 mm
With a cutting height 1.8 mm 22 amp nozzle 0.9 I measured 103 volts
And nice cutting results .
Now that the intermediate sizes of the resistors are very bad to get, I go to 200 V

Has this always been the case, usually the write function is the last one in the list.

I am very sure the .ini file was added in the first post, but I don't see it anymore?
Here again.
And yes I mentioned BACKLASH in the JOINT_1 section of the Y-AXIS, otherwise there wouldn't be any difference between 1, 2 and 3 in the picture?   There the backlash was set to 1, 2 and 3.
Why does the picture get bigger (higher) instead of doing the backlash?

After some years I thought it would be good idea to be 'up to date'.
What I always do with all my other Linux machines here, regularly
 

There is not much point upgrading from THCAD5 or THCAD10 to THCAD to THCAD2 as it is functionally identical except you can select 0-5v or 0-10 volt scales.

I personally think 150v is a bit low given cutting volts can be up around 130-140 volts. I would set to 180 to 200 volts.
