@fcwilt I remove those statements and turns out I had the XY's not lined up with the z drivers and now it works great The only problem I'm having now and I was going to spend tomorrow messing with it is that my first test print the z-axis everything leveled at home that's wonderful but then it was 5 mm away from the bed so I'm sure I've got it some adjustments to do

@engikeneer
We'll see if I get that far. I usually stop tweaking when I get an acceptable print. I'm largely going to be making jigs and stamps for leatherworking, but I hope to make some neat stuff out of NylonX

G28
Leadscrew adjustments made: -0.591 -1.472 -2.315, points used 3, (mean, deviation) before (-1.019, 0.476) after (0.000, 0.000)

WooHoo!
Thanks for the help, I really appreciate it! I increased my M671 to 3mm, reading up on the mesh.

@engikeneer thanks! I found the M671 just as you replied....lol. Is there any reason to not increase that to 5mm?

I'm reading up on the heightmap and mesh, thanks for the links!

Success! Sort of...

G28
Error: Some computed corrections exceed configured limit of 0.50mm: -0.599 -1.480 -2.324
Error: Height map file 0:/sys/heightmap.csv not found

I assume there is a setting to determine how much adjustment. But hey! Progress!

@engikeneer

@engikeneer Thanks, I'll work with that when I get home. I have to do some reading about height map it seems....no idea what it does.

One thing just hit me....I'm not sure the G30 P#'s in the bed.g correspond to the driver assignments in config.g, could it be that simple?

I do not have the exact bed file here at work, the only difference is the X,Y's are different than what I am posting here. I can post the exact file later today. Just a reminder as you look through this, everything works EXCEPT autolevel. G30 will home the z axis, and the probe works as intended.

Thanks!

@fcwilt no endstops for the z, just the BLTouch. Not sure why I get the error, "G28 Z endstop not enabled". I didn't define an endstop in the config tool, just the probe. And G30 works like a charm.

Hello! I designed and built this printer and it uses a Duet 3 6HC controller with 3 Z motors. It's Cartesian, I wanted direct drive and was concerned about weight on a core XY.

Well, it works, sort of. It homes XY, and G30 works with the Z. The motors work fine, it heats, it extrudes, even the paneldue works.

HOWEVER....I cannot for the life of me get the autolevel to work and am VERY new to duet and reprap. Lots of experience with Marlin and building standard direct drive and bowden cartesian printers.

THE PROBLEM - G28 cannot find the endstops, even though I never specified endstops for the Z in the configuration tool. The BL Touch works absolutely fine, like I said G30 works great. Can someone point me to an explanation of homeall.g and homez.g? I think this is where it is having troubles.

I HAVE....seen the link in the wiki on how to do 3 independent motors....it does not work. I have seen other articles and descriptions....no luck. I have even tried to bogart Jubilee code....still nothing.

Any suggestions are appreciated.
