Trying to set up position control mode

So when we input a jog increment of .1in, the DRO will show a .1 in change and the motor will start moving but won’t stop. If we input an additional .1 in increment in the same direction the motor will speed up and the DRO will show a change of .2 in from the start. If we then input a .1 inch increment in the other direction the motor will slow down and the DRO will show a .1 inch change from the start. 

We don’t currently get any joint following errors. 

Can you post your current hal/ini files that exhibit that behaviour?

Still sounds like a basic hal file issue

Here they are

Ok those work properly (step generator action is correct)
I suspect the problem is with your jogging setup.

( Which I cannot check unless you include the missing custom.hal
and custom_postgui.hal files )

I don’t have anything in those files. I’m very new to Linuxcnc so maybe I missed a step somewhere to set those files up? 

Looking more carefully at your hal file:

setp joint.0.jog-vel-mode 1

Means that the jog will continue as long as jog count <> 0

(this is normally intended for input devices like joysticks that return to 0 when not pressed)

for position mode jogging with a MPG, you should have:

setp joint.0.jog-vel-mode 0




 

Okay I changed it and there was no improvement. 

Does jogging via the GUI work?
 

All the results have been done with the AXIS GUI inputs.

Does the DRO show movement when jogging should  stop?
