Sorry should have stated that, all limits were checked manually and all seem to correspond to the correct input. Soft limits were turned off during the troubleshooting process.

Jazz, system jogs great, homes correctly on all three axises. I tried MDI commands and get the message "Move off Limit before MDI command". Whats puzzling to me is that Mach says this even with all limits turned off.

thanks for the quick replies
