Been a busy week but managed to get some done this weekend.
Have got the compressor moved into the container, fitted a solenoid valve, wired and plumbed.
Modified the M31 probing macro from CS-Lab and it seems to be doing all I need.
All I will have to do is have my post processor insert the relevant code and it should be good to go.
Code would be
M31 R-50 F5000
The R-50 is telling the CSMIO to probe a max of -50mm from current position. I should really have -130 there as that is the travel of my axis but for first tests I just put a lesser number.
Here is a vid of the first few tests on 1.3mm brass plate.
