Hi, everyone. I try to set up a plasma machine and it is my first time with mach4. I use CSMIO/IP-M controller. I will try to explain my problem.
When i run a G code always stops to line with M3 command. Even if i try to execute M3 command via mdi, nothing happens.
I have a touch homic sensor, i have mapped in the 'probe' input. Also i have try with G31 (G31Z-100) but when it touch to the material it stops the execution of the program.

I'd appreciate any information you could give me.
Thanks

When i am executing this code.
G21
G53 G90 G40
M06 T1
G00 X50 Y100 Z14
G31 Z-100 F3000
G92 Z-0.5
G00 Z20.0000
M03
G01 X100 Y200 F3000
G01 X500 Y200 F3000
M30It runs until the M3 and there stops. If i force the input for THC On signal continue running the rest code but without enabling the Plasma ON output.
If anyone can help with this I will be grateful.

M3 may need a S value e.g. S100 M3

Thanks Graham, but i have also try with S value.
It is a plasma profile, so i think it does not need any S value.
Also i have replace M3 command with M4. With M4 the output Spindle ON is activated and the program is executed properly until the M5, there stops and the signal Spindle On is not deactivated.

Thanks a lot.

The problem was on the version of Mach4 hobby (4.2.0.5000). I contact CS-Lab and they advise me to work with version 4.2.0.4612.
Now it works fine.
