Title: M03 don't fire
Post by: Gerhard_68 on November 21, 2024, 06:59:16 PM

Hi

I have made a plasma cutter with MACH4 and Pokeys57CNC.
Movement and probing works fine, If I press button "Spindle on CW" in MACH4 screen, Cutter starts firering well.
If I send M03 in Gcode or via the MDI screen nothing happend.

Any idea?

i'm not sure... however have you tried putting an 'S' code in the line with the M03? Could be that the Gcode won't turn it on at zero speed.  :o

Hi,

yes, I do, write

M03
S300

The speed will be displayed but the spindle on don‘t switch on.
Pokeyes guy told me MACH4 had some saftey option included now, but it seems nobody knows which options
that are

You need to put the S command before the M3 command.
I just made a thread about spindle issues.  One of my findings was the M3 not starting the spindle if there was an S0 or SNULL to begin with.  So... m3 then s300 won't work, or hasn't on the last version of Mach4 lathe.

Hi,

I will try it, but I have the problem on a plasma cutter not a lathe
I have found a new version from MACH4 -> 5536.
In this version fire plasma seems to work. Have only try without cutter
see only relais switching.
In this version are a lot of new buttons and functions.
Have everyone a manual or description of the 5536 plasma screen?
