What do you want it to do that it isn't doing now? It looks like a passable start to tweak.

@f-riccardo check the directions in which the axes move. Looking at the front of the printer, +X movement should be to the right and +Y should be away from you.

If the axes are moving in the correct directions but prints come out mirrored, check your slicer settings, because some slicers have an option to mirror prints.

Hi all, I've come to a crossroads in life and my bike project is being shut down. As a result, all of my equipment is up for sale, including this 3D printer.

The print volume is 680x624x920mm and it is set up to use 1, 3, or 10kg spools from pushplastic.com It should be easy to make adapters to use any other spools less than 10kg in size.

If anyone is interested, please browse through this thread which thoroughly details its components and printing ability.

For more information please contact Ben Claman, ben@buoyant.aero.

Thanks again to Duet3D and this forum for all the help in getting this beast to print well.

@gnydick I've tested object cancellation, seems to work fine for me on 3.6.0-rc.2.

I created a job with 7 small items on the bed, widely spaced out, and cancelled a couple of them during the print. Travel speed between the normal objects and skipped objects seems the same, at 150mm/s. Cancelled objects with M486 P4 and M486 C. It does seem to travel to the cancelled object, and then on to the next one, rather than direct from the previous active object to the next active one.

I haven't tested on 3.5.x, will do tomorrow morning.

@CaiJonas the SZP doesn't work with 3.5.4.

@luc M566 is not relevant here because RRF does not use jerk what starting a move from standstill, or when ending a move at standstill.

@jltx You can access logs using journalctl (e.g. journalctl -u duetcontrolserver -e) but I doubt anything else will show up there. Do you have any other applications running on your SBC? The message you got means something blocked the main process on the SBC from performing a data transfer.

@droftarts Most excellent. Can the documentation be updated to add that link? It would help a lot! Cheers!

@dc42 David,
Got it working.
in the end I did a auto calibrate and that sorted it. Should have tried that first.
Anyway thanks for help.

@gloomyandy Thank you!

@droftarts Thans. I'll have a look.

@wesc do you actually need the backlash compensation in Z?

Typically the weight of the bed will always keep the gearbox loaded on one flank even when you reverse directions. You'd only go across the backlash if you are using z accelerations approaching 10000 mm/s^2 (I.e. 1g) where you are outrunning gravity. Granted a bit of friction might make that number smaller in practice, but I doubt you'd be anywhere near those limits if your motor has to run through a 10:1 ratio.

It's different on X/Y axes where you don't have gravity always pulling in one direction. I know I've seen many printers with 'anti backlash' nuts on the z lead screws, but they just don't make sense to me from a physics point of view!
