The interlock is a Euchner STP-BI-3A I believe. Tuning fork looking thing goes in and is locking with spindle on. I found a triangle bit key on the sensor which when rotated unlocks it. This is great, door can be opened when machine is off. But when I power it up, I get an error and the machine won't run. I rana warm up for a few seconds and it was working as hoped: door opens and machine goes into feed hold. After a few seconds the machine figured out what I was up to and I just get an error now. Anyone know tricks to defeat this thing, preferable without breaking anything. Looks like I could cut off part of the front end of the key (pic), but would worry I'd be up a creek.
