I recently bought an renishaw OMP40-2 probe with OTS tool setter and OMI-2t interface. I located the skip signal input and have M68/M69 m-code avaible since i have no chip convoyer. I think it missed me some extra m-code. I can wire the convoyer output to machine start input probe 1, but wath can i use to machine start input probe 2? I have rotary axis un clamp (once again no rotary axis) but it need the unclamp switch input to generate MFIN. Also can i wire the probe status 1 and probe status 2 from the interface in parallel to the skip signal input or i have to use a relay that will send only the active probe status. I read about using a cheap PLC and generate exta M-code with diferent sequence of an avaible M code, but if i can avoid buying more stuff, I will be happy.

Wath is the safest way to monitor the low battery and the error output from the interface to avoid probing with an unfunctionnal system. I tought to interrupt macro, simplier or better way ?
