Title: Set UserDRO value from gcode
Post by: djreiswig on May 04, 2024, 07:25:03 PM

Is it possible to set a UserDRO value from gcode?
I found #99aaa = bbb works for OEM DROs, but trying it with a UserDRO number causes mach3 to crash.
I haven't found any documentation explaining what #99 is actually for.  I did find a reference online noting that is was possible to set a UserDRO from gcode, but the poster didn't explain how.

i think the only way will be to create a customised macro (m123.m1s for example) an call this in Gcode.

code for macro would be:

Code: [Select]

  DRONum = Param1()
 DROVal = Param2()
 SetUserDRO(DRONum, DROVal)

usage in G-code would be:

Code: [Select]

  M123 P1100 Q1234

Thanks.  I thought I might have to use a macro.  I wasn't sure how to send parameters to macros.  Your idea should work.
