This is the Cerberus Gigante Deltabot. 5' x 34" print envelope. I didn't use the expansion board, but I am using Duet2 wifi with external drivers which theoretically 'could' have been connected that way? In any case, it's a cool deltabot project. Currently in operation at Arizona State University in the Grant Street Studios 3D media lab location. I'm the 6'3" shiny headed dude in the photo, for size reference.

First day, delivery!

Or just a big tornado print that was ready when I came back the next morning?

@phaedrux -- Problem resolved on my end.

Thank you very much for getting me over that hurdle. I'm very appreciative of your time and expertise with something that really had me stumped.

Last evening I switched out the motor and endstop wiring (physically moving the tower mapping to X=Z, Z=Y and Y=X) and ran the same print. The error stayed with the original tower even though it is now mapped to believe it's the 'X' tower. I then interfaced with the motor using the Teknic MSP software and using the 'scope function it appears that the motor is actually losing positioning early in the move and never recovers. Because it was getting late and it was not at my shop I didn't delve into the exact number of steps it's losing. It's just strange that it loses that positioning in one direction only.

In any case, I don't think this is a Duet hardware or firmware issue and I'll be contacting Teknic for an RMA.

Regards to all and thanks to you guys for developing such a configurable controller. Overall I'm extremely happy with its performance on my most recent printers, and I've begun retrofitting some older ones too.

It struck me last night as I was falling asleep that I wasn't seeing the super basic and easy way to accomplish what I want.

The best overall solution would of course be to set up a dynamic macro to repeat any currently selected print via a physical button. And that would require knowing the current print file name and path which would require upgrading to RRF3.1. That way the button would be maintenance free.

In my case I'm printing a known file over and over and I don't have time to upgrade right now. So I'll simply hard-code the macro with the filename I want to reprint. If that file ever changes due to versioning, etc. I'll just edit the macro.

M32 "0:/gcodes/Cerb400_1-1.0mmNozz/PETG/30xMB_V4.0-Plated.gcode"

When I finalize the physical button housing attached to the printer it will include several other momentary push buttons for preheat, motors off, home and board reset. Maybe I'll include a little clip to hold a post-it with the macro-filename listed on it.
