General Mach Discussion / Re: Problem with computer running mach3
« on: June 01, 2011, 09:33:25 PM »
Maybe I don't have this all figured out.....
Motors sound like they are running properly. So does the computer and the setup in general.
I'm now re-tuning the motors as described in section 5.5.4 in the mach3 setup guide. When running this code:
F1000 (i.e. faster than possible but Mach3 will limit speed)
G20 G90 (Inch and Absolute)
M98 P1234 L50 (run subroutine 50 times)
M30 (stop)
O1234
G1 X4
G1 X0 (do a feed rate move and move back)
M99 (return)
The machine will jog back and forth but the table never fully moves to x0 or x3. More like.... .5 and 2.5. I see this physically on the machine and also on the mach3 DRO.
After the program finishes, the machine is back exactly where it had started.. So it doesn't seem to be missing steps. I have also tried simply jogging back and forth at full speed trying to get it to miss steps, but it ends up right where it thinks it is.
I'm not sure what I'm missing.... Why wouldn't the machine be going all the way to x3 or x0
