ello all, I just converted from m3 to m4 with a new hicon 7866 controller.
I'm running steppers , with no feed back to the hicon,
when I'm running my feed rate display keeps changing...????
if I command a G01 Y60 F125 the feed rate display will bounce between something
like 124.53 to a 125.8 this seems strange to me, why would it be changing? also the movement is jerky I can feel it is not smooth.
Can any one explain this to me?
this evens happens even if I use a G61 .
not sure this will work but here is a video of what it is doing.
