We have an older Charmilles EDM, Roboform 20. It was running fine until we had the main cabinet cleaned due to an unrelated smoke issue. Now, when we try to run a burn program we get two errors:
A638: Smoke suction off
E640: Smoke suction error
We have verified that the building ventilation is working at the EDM, and replaced the microswitch for the suction paddle that detects the ventilation. We have even tried to manually close the switch to trick the system to verify that the microswitch is not the culprit. We still get the error. We would check the PCBs in the cabinet, but don't know what we are really looking for. Any insight would be greatly appreciated.
