General Mach Discussion / Re: Bridgeport series 2 only stall on y when spindle running. Why???

There are two things I can't figure out about Mach.  This is unrelated to my stalling problem now fixed.  One is how can you see the feed rate when jogging?  After reinstalling Mach I lost this feature.  the other is I get an error in the circle cutting wizard brian barker. It says max limit>soft limit or something like that.  I need to go to the shop and confirm that.  Anyway it wont allow me to use the program.

No I don't think it can be low voltage because the spindle motor is run off of a three phase converter.  None of my wiring is shielded.  You may laugh at this but I took My y step wire and covered it with tin foil, about a 12 inch by 12 inch piece.  Guess what.  Problem solved.  It no longer stalls in the y with the spindle running.  Has anyone ever done that before.?

I am having trouble with the y stalling when fast jogging on my bridgeport series 2.   It only stalls during fast jog and , this is important,  WHILE the Spindle is running.  I am using ss relays to turn on  my spindle.  If I have the power off to the spindle and just activate the relay, the magnetic switch comes on as it should.  This does not cause the y to stall.  Only when I actually have the spindle running does it stall and only fast jogging and also rapids using mdi.  Only in the Y!   I can rapid at 125 on x and y with 10 acceleration when not having this problem.  I have the debounce set to 10000 but had it at 500 no difference.  Pulse width makes no difference. set a t 4 now 

 I have switched geko drives to the other axis.
I have switched the pins on my cnc4pc bob
I have put a new wire on the step for the y

I am running keling motors

Any thoughts would be greatly appreciated. 
I have included my xml setting
Sincerely Mark
