That's when I realised that the Mach3 and macros that came with the machine clearly did work with two probes and I found the "setdatainput" command in the macros supplied. It is virtually unmentioned anywhere (according to Google) although I found a reference that says it is only in .066. The current question is about whether or not that command is in the French version. Not clear why it would not be, but details of Mach3 development are lost in the mists of time...
Ah well. If uccnc has taken the problem away then that's a win.
So. You can use mach3 with the uc300 with the plugin.
I have both Mach and UC set up to my 300 on my laptop so I can switch between the 2 whenever I want without messing them up.
If you did want to do any mach testing it shouldn't be a problem.
