OK, I haven't perfected my machine yet to 100% reliability. A lot of the times I get a soft limit exceeded error and I am usually in the middle of all my axis and all the way up with Z of course. This is a random occurrence. in the beginning of running this new program I got two occasions where the machine skipped the Z move completely about once every 30 parts. Today I had a situation where the program skipped the Final G0 ( I usually put that there so my vise is more easily accessible). I am praying all the way that mach never skips a Z move before rapiding ( $100 keyseat cutter) or any other moves to get the cutter out of the workpiece. This I get besides all the extra steps here and there. Maybe its because of servo 120 VDC lines next to Rj45s that transmit step and Dir signal? I just had to change my ESS limit debounce to 500 microsecond and that's after getting all the fancy shmancy input and output line reactors for my VFD and RFI/EMI filter installed.

On a side note, I am thinking aluminum screen faraday cage grounded and placed around VFD? 24VDC limit switches, shileded cable for my step and dir signal. any other suggestions?
