General Mach Discussion / Re: No PWM using spindle output for Laser

« on: March 31, 2023, 09:55:25 AM »

Thats a very inefficient piece of Gcode with multiple passes which cut through in places but other than that it worked just fine. The laser turned off when it should.

Question: Do you have a genuine Mach3 license and is it registered in your name ?

The forum is a little bit cranky and every image / attachment posted needs to have a unique name (which has not been used by anyone before).

I have checked your Gcode file and it all looks OK. I ran it with my laser and no problems. Exactly why your laser is refusing to turn off quick enough on the final home move is, at the moment, a total mystery to me. Perhaps you could attach another problem Gcode file for me to try.

That is the latest version.

Perhaps check the version of the rnrmotion.dll that you are using - if it is 1:2052 then, if I am not mistaken, that is the latest version available.

If its any help - If you detail exactly what you want included I can modify the post processor for you.

Not sure if this answers your question...

The M11/M10 commands (for laser ON/OFF) need to be followed by an axis movement to be activated.
Make sure you have a G0 or G1 command following the M10 and before M5 at the end of your laser job.

The laser staying on or failing to turn on/off after a Pause or Estop is again related to the lack of a Gcode commanded axis movement following the M11/M10 commands. This explains why it returns to normal operation after encountering these commands when running further in the Gcode file.

I am pleased it worked for you.

This is perhaps the best document to start learning about creating macro's for Mach3 ;

Like everything in Mach there is more than one way of doing this. One way would be to create a macro which will essentially press the on-screen buttons you require when it is called within your Gcode file.

Just as an example the macro could contain the commands…

DoOEMbutton(1008) 'press ZERO X button
DoOEMbutton(1009) 'press ZERO Y button
DoOEMbutton(1000) 'press CYCLE START button

Call the macro M1111.m1s and save it in your Mach3 / Macros / Mach3Mill folder (or whatever profile you are using folder) then when you add M1111 to any of your Gcode files it will execute the macro.

You may need to elaborate on this macro and there is much documentation available on VB scripting language and DRO buttons, etc. available on the NFS website here; https://www.machsupport.com/

Just to get you started I have attached a copy of the above macro in a .zip file.
