Many thanks for project,all works!!!
It is a pity that there is no development:
1)ramp speed
2)speed control by any pot.
3) A -Axis
4)switch PC/JOG
I have added DS1669 (digital potentiometer) for speed control at remote control by 2 butt. up/down
I belivie that is a lot of peple wishing to a get a finished ver.
for a remote jog controller ,
Certainly for a reasonable payment
Many thanks again
