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.
