Tool Setter and Touch Probe Wiring

MR-1

Both the version 2 tool setter and touch probe have a three pin connector. Anybody know the wiring for each of the pins?

It has not been published. @AlexW might be your best shot at this point.

@AlexW Do you happen to have the pin wiring info for the version 2 tool setter and touch plate?

I have the colors to pin mapping on my GitHub page: GitHub - alexphredorg/mr1: Langmuir MR-1 configuration for LinuxCNC

Langmuir’s colors are non-standard, so I need to double check the mapping. I may have a chance to do that tomorrow since the cover is off of my control box.

Are you trying to adapt them to another machine?

Thanks Alex. Yes I am trying to adapt to a Masso controller.

Since you already have the machine apart you can also figure this out. The three pins are 5V, ground, and signal. The signal pulls low when triggered and on my enclosure this wire is blue (but I don’t know if that is consistent across machines).

I had to add in a pull-up resistor so that it stays high when the probe is disconnected. Your Masso controller may give you the option to configure this in software or with a jumper.

On my machine it looks like:
3 = ground
2 = signal
1 = 5v

Okay thanks. I was told that version 2 is 36v.

Version 2 doesn’t rewire anything in the control cabinet, so the VCC voltage should be the same as v1. Maybe it should be 36v and that is why I don’t have working LEDs since I’m running it at 5v.
