@T3P3Tony I would suggest either removing or updating the 130mm dimension up the left side as well, as this dimension is in fact 129.5.

Splitting the proverbial hair, I know!

@dc42 Ah, I see. I think that would be a good edit to clarify what that jumper is doing.

@dc42 Gah! I saw those holes in the 6XD board by the drivers and was wondering what one would mount there. I don't know how I didn't put two and two together. Well, there may be a daughterboard version coming in the near future!

@droftarts Yeah, I was caught off-guard a bit when I came across the above figure, as I was just assuming it would be 5V. To make matters worse, the position reference inputs are Pulse, Direction, and Clear, not Pulse, Direction, and Enable. To turn the servos on, the drives require a separate, 24V input. So, talking with these drives is proving more involved than I hoped. But, they have 24-bit optical encoders, so, you win some, you lose some...

You make a good point to run single-ended pulling from a 3.3V pin instead of the 5V, and I have to admit that didn't even occur to me, but it seems like a reliable fallback. I do still like the resistor approach if it works though, just because it keeps all the connections physically discreet.

Come to think of it, though, any chance the EN(-) pins on the 6XD are 30V tolerant so I could actually use them for enable/on signal?

Thanks Phaedrux, I had tried all of that with no luck.

o_lampe wins the prize, my end-of-print macro contained

M141 H2 S0 M141 H3 S0

When it needed to contain

M141 H2 S0 M141 P1 H3 S0

Sending "M141 H3 S0" immediately--and unsurprisingly--replicates the problem, so, there we go.

Thank you both very much! My printer otherwise seemed to be in perfect working order, so this was really bugging me more than it needed to.
