Mach3 Gcode movement help
« on: September 25, 2020, 12:30:54 PM »
i have just installed Mach3 on a new computer running window 7   this mach3 program was moved from my old computer  that stopped working.
after i installed the program and get the motors tuned  i tried running a gcode file  and nothing happen.
The DRO moves but no movement  on the motors.
All three axis move if i am moving them using the keyboard keys.
Thanks for any help

Not enough information given for people to help

But first rule out these:-
1. Work coordinates G54  is not yet defined so your motors cannot move outside of limits?
2. There is no F statement?
3. Gcode file is in mm without but G21 when your machine is in inches?
4. A rotary axis (like A or B or C) not correctly defined?
5. Reset button not pressed and {ref all home] not yet done?
6. Charge pump or enable signal not correct?
7. Soft limits triggered or limit switch triggered?
8. Fuse in control box has blown?
9. Axis set in wrong direction?

Thanks for your reply.
I found out the cause of the problem.   it was the mach3 cycle start   for all the years i been using Mach3 i only needed to press the cycle start button once to get the file cutting.  just by accident or frustration i press  the cycle start twice and the file started cutting.
Pressing once just started the timer going.
not sure why   any idea why?

Could there be a pause e.g for manual tool change in the program that requires another [cycle start]?

check  Config -> General Config -> Tool Change

what is selected there?
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

then i expect, that there is a M6Tsomething at the beginning of your code.
