Got it. Finally understood how it works with the positioning of the laser and the materials. When I have some time I shall test it and post the results.
Thank you.

EDIT
I am having issues testing the pots, and made a post here, but I went ahead and moved it to its own thread. Didnt seem logical having it barried in this thread.

Did you see my post explaining the measurement and adjustment?

Power on, motors not moving.
Set your meter on VDC and 2000mV range.
You expect around 0.3 (300mV) for the X-axis driver and 0.6V for the Y-axis as its driving both motors.

Don't press down on the pot or you'll change its resistance, just lightly touch on the wiper.

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.

Im sorry, I am a complete idiot. !!!

I did not have the laptop booted up, so the board wasnt getting signal from the USB to activate it fully.
Took readings and adjusted it to 0.3 for X and 0.63 for Y

Thanks for putting up with this idiots questions for nothing, lol

Doing some more testing now...
Having the X at 300mV and the Y at 630mV does not work, it cant move any direction.
I have to have the X at 356mV at least, and Y at about 746mV... and even then, its quivering instead of moving at times.

I will try to loosen the belts even more, they dont SEEM too tight, but Im not really sure.

EDIT
OK, more tweaking. X is about 356mV and Y is about 678mV, loosened the X belt slightly and loosen all the rollers just a tad.
All seems to move smoothly now. Hope thats not too high on the drivers. I did order some tiny heat sinks for them though for the heck of it.

You should be fine at those values, anything below 800mV shouldn't require heat sinks (per the spec sheet) but still not a bad idea.
