You could submit a software change request to Centroid, suggesting that if "G code preview" is enabled with P417, and the last job ran to a successful completion, then the CNC12 main screen display should (perhaps after a short delay) revert to displaying the preview of the top of the job...

Now I still don't know how to get M30 to automatically jump to the beginning of the program without restarting it. So basically as if you had just loaded it. Maybe someone from Centroid can say something.

with M30 macro (M02)

no M30 macro

chapter 6

P 417 =1 is already set. However, it should not stop at M30 after a program has been processed. It should rewind to the beginning of the program.

M30 is not supposed to do anything other than display the program from the beginning on the screen. do not restart and run. The background for me is to know exactly which program is loaded. That's right at the top, but I don't really look there all the time. For me there is no limitation on the prog...

M2 is not the solution. The control waits for the cycle start on the M30 and when I do that, the program restarts and waits when the tool is changed.

The M30 should reset the display to the beginning of the program, not restart it.

Who can help me? I've studied TB300 and also the instructions for writing macros, but I can't figure it out. (I can only think of M5 and Goto 0, but it won't be that easy.)

M30 should:
jumps back to the beginning of the program
