Hi, I have a QUAD 4C mk2. I taught pickups and places from HHT. If I test them individually (RUN STEP PICK/PLACE etc...) before building the sequence, everything runs ok. After the sequence was built, everything goes wrong. Every PICK or PLACE ends in a Z axis bottom crash and an error message "LIMIT ERROR" Z 0,-10 Taught coordinates and LAE data remains unchanged. Reteaching every Pick/Place is ineffective. However nozzle change instruccions are not affected Power off and restart not eliminates the problem.
I ommitted the use of Central Controller to eliminate variables. The only way to get out from this situation is downloading an used program from CC, the instructions can be taught and work fine, until... you know. Anybody has experienced this phenomenom? Thanks.
