Hi all, I was wondering where I could find the supplemental homing switch guide for the m3. Also, I was wondering if anyone had a close up picture of their homing switch properly wired via the spade connectors? - Do you use the shrink tubing? - Is the spade connector completely slid onto the COMM and NO terminals? It seems like a very tight fit and was wondering how people got it on there. - COM is black wire going to RIGHT and NO is red wire going to LEFT? Best and thanks Attachments:

Hey. The supplemental is in the bag with the homing kit. If you need it posted here let me know.
Black is to COM and red is to NO. The labels are molded into the switch. The heat shrink goes over where the wire meets the connector. The connector will fit snugly into the switch terminal..I like to hold the bottom of the connector with a pair of needle nose pliers in one hand, support the switch with the other, and push it on.

Thanks Derek!
I misplaced the supplemental guide, if you could post it that would be awesome.
Great tips on connections, will do exactly that.

I borrowed a fancy crimper from work, but it didn't work either. I ended up using my regular old crimpers that I've had forever. I made sure that the wire was held securely even if the terminal looked a bit smashed rather than properly crimped. And I did use the shrink tubing. Just make sure you put the tubing on the wire before you crimp the terminal on. I remember that lesson from high school.
And yes, the terminals are really hard to get onto the switch blades. I used needle nose pliers to push them on.

Couple related questions: 1. What size spade connector are those? 2. Does the homing switch have to have the noise filtering capacitor?
I ask because I have X and Y homing working but not Z (tested using verbose output in UGS). I bought new homing switches (with no capacitor) and wire, but having hard time reusing spade connector. So far can't get Z to show in UGS verbose output with new switches and new wiring, but also still working on it.

They are .187" female spade connectors according to the homing switch instructions.

Thank you - does anyone know if the noise filtering capacitor is required for homing switch to work?

I don't know if the capacitors are absolutely required for the homing switches to work. Can you check for operation of the switches in UGS on verbose mode? Also, here is a scan of my homing switch instruction sheet. Millright M3 Homing Switch Instructions.pdf (293.76 KB)

Hi rowiac you've been a huge help, thank you! I've definitely used UGS Verbose, I have good X and Y homing results but not Z - it just doesn't show when triggered.
Never got those switch instructions (with Carve King) so I appreciate having the scan! I'll follow the part about continuity with multimeter.

Also, here is a scan of my homing switch instruction sheet. I just was coming to look for this very homing switch sheet. Apparently lee my switches were not set up right when I got the machine from my uncle. So lets hope this hasn't been why I'm always having issues with it...grrr

Yeah, it seems like this sheet should be added to the Resources section of the main site. Glad it's coming in handy.

The capacitors are a filter for possible noise that can interfere with the switch signal. Make sure the leads are solid and not broken at the crimp connector.

Sorry for the cr@ppy quality of the scanned sheet. I took a picture of it with my phone and used a scanner app to make it a pdf. The sheet was not very flat when I took the picture.
