Hi all,
So I have finally finished up my custom made machine and running into one irritating issue that maybe you can help with.
To start of I'm using the PoKeys57CNC together with postep60-256(for XYZ) and I'm controlling it via Mach4 and the USB-interface between computer and PoKeys57.
My issue is when doing manual jogging in Mach4 with the continued options the axis behaves abit weird:
The acceleration is smooth, the full speed is going smooth but as soon as I release the jog button the stepper motor stops for ~0.1 seconds before starting with the de-acceleration.
This of course is making me loose steps since the stepper is going from 100% speed to 0% instantly and then "pausing" for 0.1 seconds and then starting the deacceleration from 100% -> 0%.
If I jog with increments in Mach I do not get this issue.
What is more "weird" is that if I use the pulse engine from Pokeys57CNC own software the steppers do not behave like this, as soon as I release the jog button the transition to deacceleration is smooth and no "freezes".
This of course makes me think that the problem is Mach related.
If I run a g-code program I have no problems with this either.
It's maybe not the end of the world since I can manually jog with increments or the MDI but it is nice to jog a great distance with just holding the key down.
I will try to make a video later on so you can see/hear the issue for yourself.
Thanks in advance!
