Yes, I saw your post, that is what I was going by, just tried it again...
Set MM to 2000mV, plugged in and powered on the engraver.
With the leads NOT touching anything I read 006 and 007 (no decimal point)
When I touch them to either of the drivers, the reading does not change at all.
Tried it with a second multi-meter, set to 200mV, reads 0.00 on both pots.
Does this mean they are simply set really low? Seems they wouldnt work at all if they were that low.
