Hi, I’ve had my mini for about 1 1/2 years and it’s worked great. But recently, the back Y endstop doesn’t engage and the mini will often try to force the plate off the back of the rail when homing. I replaced the back Y endstop switch, but it didn’t fix the issue. So tonight, in desperation, I took the cover off electrical compartment and looked at the mini-rambo board PDF off the lulzbot development page.
Using a multimeter I’ve been able to isolate the issue to either a break in the switch wire or on issue with the wire connector housing on the rambo side. I know because if I check the connectivity of the red wire my multimeter beeps but I can’t get a reliable beep on the black wire. Sometimes if I twist the wipe etc, I get the beep.
To make a long story short, I want to replace the connectors on both ends of the Y endstop wires(both rambo and switch side). The PDF calls for a 4ucon 02005 on the rambo side. I can’t find this part or the wire housing on digikey, so I was hoping someone might be able to give me a housing part number from either digikey or mouser. A part number for the connectors on the switch side would be great as well.
Thanks in advance and if this isn’t the correct place to ask a question like this let me know and I’ll try lulzbot technical support tomorrow. But since the printer is not under warantee I’m not so sure I’m going to get much help from them.
