Not quite what I was looking for but something like this. SOme have stops that let you limit the number of positions

In the US, this is all Digikey has that's coded for hexadecimal. My own personal lack of vocabulary for searching is also something I hope to improve as part of this conversation.

Me too! so I am hesitant to make a recommendation for that reason but I think that a 3 pole or 4 pole 12 position rotary switch also does what we want. eg decodes a position to a bit map on the poles.

As an aside, I am also a little confused why PCW suggested 00, 11, 01, 10, instead of 00, 01, 10, 11. It seems more logical to me to order it like legit binary, and it's not like it's harder to connect it this way.

The 4  --> 2 diode encoder circuit I posted is in binary order but you need to consider
that the 7I73 inputs have pullup resistors so are high when unconnected and low when
grounded through a diode so:

SWITCH POSITION
0  Grounds inputs 0,1 with CR1 and CR2 = 00b = 0d
1  Grounds input 1 with CR3 = 01b = 1d
2  Grounds input 0 with CR4 = 10b = 2d
3 No connect so = 11b = 3d
 

Can you recommend a source of information that can decode what you just said?

If this is happening at the end of cuts, it’s generally caused by the arc going out either because the slug dropped or the material was already cut while the machine still has some distance to move before reaching the M5.

If that’s the case, then you can set a lost arc delay as described here:
