I do have a Chinese mill that works very well in general but does have some
noise issues. There are some mistakes made with the wiring, kind of obvious
stuff like non shielded cables for the VFD, high power cables running across
the PP in plug and stuff like that.
I start the G code, the spindle starts and the coolant starts. X/Y move to
the first cutting position but will not reach it precisely as for short
times the motors stall instead of traveling while the spindle rev's up. This
is not influenced by the speed I travel. I can see the stopping/stalling on
the Mach3 screen too.
I manage to get around the problems by starting the spindle and coolant
while in PAUSE after moving to the first X position. This works ok for now
and I will look into the noise issues very soon.
For now I would like to know what settings can influence/enforce the noise
sensitivity. The following points are of interest to me:
1) if the acceleration is set too low, can that influence/lead to motor
stalls?
2) if the timing for step pulse and direction pulse are set wrong, can that
have an influence?
3) the signal settings for Dir low active / Step low active , can they have
an influence? How can I set these right?
Any advice welcome,___
