@dc42 The reset more than 17 hours prior was before starting the print. I generally always do a restart, then bed level etc before a large print.

Oddly enough it says print 100% complete but it is only about 1/2 complete!

Short-duration prints (up to about 6 hours seem to go fine; however, longer prints stop mid-print. Print head stops heaters off right in the middle of the print.

Simplify 3d is the slicer

Any thoughts?

Thanks for that! When I do that, the carriage moves towards the "b" motor, not the "A" motor. I would gladly move the switches back to where I currently call 300,300 to match yours if it would be easier.

Thanks!

@droftarts

Thanks everyone!

I have been looking at those pages and I believe maybe the motors may be running in the correct direction, maybe my homing code is all wrong, or I am missing something fundamental.

I moved the endstop switches as seen in the pic plus drew in arrows for directions print head moved when codes were entered. I also indicated where I think 0,0 and positive 300x and +300Y (or whatever the correct number is) Maybe I don't understand something.

Thanks for any help!

I am trying to learn the Duet 6HC by installing it in a core xy printer. I can not for the life of me get the printer to move in the correct direction, home etc. I have a Tronxy X5S that I purchased just to learn on, I removed the electronics and wired up the Duet.
I have built several other printers from kits and want to be able to make CNC machines in the future. I have decent training in electronics and wiring, so everything works from that perspective. It simply goes the wrong way.
I have tried to find my error and spent weeks looking at posts here, I have moved my end stops to match the "A" motor. I seem to be missing what everyone else knows. What is zero, what is the correct polarity of the coordinates for the machine? Is there a good book or manual explaining this?
Should I just rebuild it to be a cartesian printer? Is that easier?
Any help would be appreciated.

Thanks! Unfortunately, I had to leave for work and I should be able to try these finally next week!!

I specifically purchased a Duet 3 and a Tron XY to learn how to use these boards to eventually build bigger machines. I can't get the movement right. It is a core XY and attached are the motor setups. I have tried various combinations unsuccessfully, as well as copied others online with no success.

Thanks!
