General Mach Discussion / REFERENCE MACHINE COORDINATE FROM WORK POSITION "0"

« on: September 14, 2013, 10:34:57 AM »

I want to go to, say, x13 y17 z-2(machine coordinate) from a current job that is at job position of x0 y0 z0 (machine coordinate x30 y12 z-1). How do I reference it in my
Gcode??? I may be at any job of 0.0 depending on the job.. I could go to home 0.0.0, but for speed I would like to move from where I am...

Finished Screens / Re: Mach3 Screenset 2010 New Auto Z Problem

I had the same problem.... took out the breakout pcb and cut the run back onto the board to keep from interfering. Was pulling the voltage from 5.09 down to 3.69v.. caused intermittent failures...

right... I have been tuning Mach3, not the gecko....

I have set and reset the tuning. Lowered velocity and accel, raised velocity and accel... set as per K2. Doesn't seem to help. I worked 25 years as a computer technician so my knowledge base is more than basic, (I think anyway) . I thought as you that it had to be in tuning, but have not had any reason lately to think so... I even put a higher rated servo on the cables and it also failed after tuning... I thought It might be the code disc, so bought new style servo w/o code disc. exactly the same... Think I might just be stuck with it faulting (sometimes)...

Hood, there is no limit on the A axis.... It is set to go and go and go.....

K2 says any chk light is a servo fault of some kind... that is all I know... I have talked to K2cnc several times about this problem.. Maybe a total new controller is in order... everything works.. wrapping vcarve and aspire files works fine, just when I run long taper cuts or straight rounds in the (what I call) clockwise direction... Of course I ran 4 runs today... 29" @ .05 cut per inch and it ran perfect.... Who knows... ?? not me.... I spent money on servo, gecko, breakout pcb, computer etc...What the significance of only one direction error is beyond me...

For some time now I have had a problem with my A axis on a clockwise turn getting a error.. I have changed the gecko, breakout pcb, parallel port cable, computer, reloaded new versions of mach3, erased the hard drive and reloaded everything, took off all unnecessary programs, swapped the gecko cables, swapped the servo motor with a new one, took the motor off the assy and ran by itself with (G0 a40000) check light... run (g0 a-40000) ok... I have a K2 cnc and they have no clue what could be the problem... Anyone had such a mess...

Sometimes it works ok......Re grounded box and no help...I thought about going to smooth stepper, but don't want to spend the money if it won't help.... Some of the runs I do set (A) as much as 212,000. I tried changing kernel speed, no help. Motor speed, no help.... H E L P if U can... I am not stopped from working because I can run in CCW directiion, but I have set up to be able to run in CW most of the time...
