Hi all..
One day, in the dim and distant future, I will finally kick all the bugs outa this cnc build, but not today it seems...
When I am jogging the x axis (dual drive nema 34's, slaved together in Mach3) it moves freely, until I try to also move the y axis simultaneously.. Then an awful grinding noise and the x axis completely stalls (no movement)... First picked this up last week when it was cutting a circle and it was rapid moving (G0) to the next cut, it stalled the x axis and therefore did not move to the right place..
I have since redone all the wiring and triple checked all mechanical movement which has made no difference, in fact I would say it has got slightly worse if anything..
I am using a Uniport controller, 2 x PM752 drivers (x-axis) and a PM540 driver for the y.. I have wired it all according to the plan shown here..
Anyone encountered this before? Any ideas? Wanna lend me a really big hammer..?
