General Mach Discussion / 'y' and 'z' axis working together?!?!
« on: January 28, 2009, 10:51:00 AM »
Well I've build my own cnc.I think it has been a fine job, I used ball screws,linear guides from nsk,motors with 15 kgf.
My control works fine at even 7 amperes.
The problem is:
I open mach3, load the g-code that I built just for test,it moves the 3 axis one at a time.
when 'x' works it works very fine,smooth,fast and efficient
when 'y' works it won't work,just whistles (very high frequency noise) and gives some 'cracks" but no movement.
when 'z' woks it works as fine as 'x',but (for my despair) the 'y' works together with it!!.
I've tried everything,but something is still missing.
Please remember I'm not an English speaking person,my native language is Portuguese,so I apologize for some mistake in advance!.
Can someone help me find out what it could be??
