    It’s been a while, since I’ve posted advice section https://www.v1engineering.com/forum/topic/planning-my-first-mpcnc-build/

    and wanted to update on my progress, I could use some help still. I’ve got it up and running and just machined foam board.  Everything seems to be working OK. I am still working out some details. Like the  Z end stop which is currently rigged with aluminum tape.  I’ve got a mini switch coming.

    On the crown test I thought it would have the origin at the opposite corner of the machine, It still worked but I’d rather have the origin on the opposite side. It drew over the lines twice so it seems pretty accurate.

    I squared it using an actual square and M666 X1.75 gets it as close I can tell with paper n pen.  I would like to move the stop block a notch 2mm and go with a smaller correction in the opposite direction,would that be (M666 Y.25)  ?I leveled the bit to the table with the feeler gauges. And set the dewalt perpendicular to the table, with the thingy. When I was in machining this piece out of the blue foam, I tripped over the power plug and cut power to it, but I was able to restart the cut in the same exact place and finish it. The crack in it is from double sticky tape to the table (oops, I won’t do that again with foam if I actually want the peice), I don’t have an actual waste board yet.  So I didn’t cut all the way through.  Anyway I don’t understand everything I’m doing with ESTLcam yet, I was just copycating your tutorial.

    One more thing I have 483mm square of travel, And if it’s over 250 mm away on either axis it errors out. what do I change in the firmware to fix this (search keyword or phrase)? This is my rig for the Z endstop,  if someone has a better one I’d like to see it.  I also have this pi optical trigger I might use. Seems it needed +,- and signal tho.  And I’m not that great at the software side of this.

    Generally we don’t use Z endstops as an actual endstop.  It gets used as a touch probe.  Just don’t hit home all in repetier and should be good.
