We need to check on this, I think 0 might actually mean no max. To alleviate any ambiguity, I'd use -0.001. Or test this, have we tried moving to 0.02 with max set to 0?

No, setting the limit switch to zero just applies a limit at position 0. The Enable="true" would be missing if it was disabled. See below example.

FALSE Looks like:

TRUE Looks like:

Thank you for taking a look. Also, Epics limits behavior seems improved. It wont let me exceed max PLC limit pos which is nice.
