General Mach Discussion / backlash program will not run

« on: January 22, 2007, 11:29:46 AM »

im useing the newest version of mach  .  it seems on every version of mach3 when i enable backlash the program stops about 5 lines down(units/measure)
i dont recall having this problem with mach2 but then i only used it for about 2 months  as soon as i uncheck the the backlash enabled button  WALA  Bertha comes back to life. I have my backlash setting set at .004   for  y,x,a this is a plasma table and i have cv unchecked and exact stop checked  i must be missing to check a box or something all help would be gretaly appreciated

i dont have any limit switches up yet just homing    . i was told to make your gantry square and easy to adjust run an x and a a  dual drive  the run 2 switches ,one each side  so when you home you can just move one of the switches forward or backward to make your gantry square   so i would think that the gantry would just stop on one side and the other side would keep going until it hit its switch i geuss i was wrong  hmmmmm

I have my ganyry slaved x to a  and it seems that when i push the homing button to square the gantry the first switch it hits stops the gantry instead of going all the way to hit both switches to make the gantry square  . i have all the buttons checked in homing an the ports and pins all help would be greatly appreciated . Just to make sure in doing this right   when you want to square your gantry you just hit home next to the dro is this correct

hey Chaoticone  i was sitting here tearing into my box i was going to put that other power supply the 48 volt  56000 capacitor one out of the centroid controller in my plasma box i was wondering do you guys think it would matter if it is like a 900va  or it really wont make a difference
my motors are only going to pull 5 amps all together this supply is set up for 9 amps on each motor LOL just making sure im not going to fry anything
