@dc42 Thanks - that seems to work ok in single motion system mode - I have been able to set the V axis to not come within 100mm of the Y axis which is exactly what I need.

I can't test it in multi motion system mode due M400 and M598 not releasing drives - which still seems to still occur in the new rc1+1 version you sent. - see https://forum.duet3d.com/topic/36866/multiple-motion-system/64?_=1741362599789

@droftarts GRAZIE

@Nakcam it's all fine with your information, I have "only" a time problem. I can proceed tomorrow for a few hours.

@T3P3Tony, thanks a lot for your response.
Seems like an interesting solution to try.
Will surely put it to the test.
Best,
Jad

@Mr-Crispin he has done the kinematics calculations in his gcode generation program. so in this case the Duet does not "know" its multi axis printing. @JoergS5 has done some work in implementing variations of robot kinematics that run on the Duet boards themselves.

@shaunppl this is the subject of a feature request:

https://github.com/Duet3D/RepRapFirmware/issues/780

T3P3 created this issue in Duet3D/RepRapFirmware open Support configuring an axis as "continuous rotary" #780

@o_lampe Separate thread now created - over here
https://forum.duet3d.com/post/349140

Would be interested in your thoughts on how do to the Z hoppers.

@gloomyandy Sorry no idea about G38.2 I've never used it.

@Carter3DP you will need to reverse the direction of the homing moves for the proximal and distal motors, and switch the proximal and distal homing switches over from low to high end or vice versa.

@fromwastetowind I think this is an 'inverse' Polar printer, and it is irrelevant to the firmware if it is the crane that rotates or the bed. The nozzle just needs to travel along a line drawn between the centre and the circumference, ie along a radius line.

See https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_Polar

Apart from the links already mentioned, there was a similar printer design (though running on a hacked version of Klipper) at SMRRF: https://www.youtube.com/live/Hlw3mt-x0nE?si=amwlz8DMR0daYQjS&t=1437

You should be able to put a print anywhere on the bed, just not in the centre. M669 Raaa:bbb defines the minimum and maximum radius in mm.

@OttoJiang I don't recommend it, because this kinematics is only one of several ones of robotics kinematics. When they are complete, we can github it.

As an overview please see https://docs.duet3d.com/User_manual/Machine_configuration/Configuring_RepRapFirmware_for_a_Robot_printer with additional documentation pages.

@dc42 can i have an answer please?

@Toaster0042 you're right, I should inform, I will prepare an update.

@dc42 Thank you for the response. I will attempt this.

Sorry I forgot you were working with external drivers here.

As this thread has grown to nearly 100 posts and has involved several issues, I think it may be best if you can create a new thread with a detailed restatement of your current issue. Please include the basic details of your setup and the hardware used. Please include your config.g as well.

@Texas_Mike please share config.g and homing macro files (home/y/z/e/f.g, and homeall.g).

@David-Piska said in Clog detector make random filament missing errors:

thanks to Modix3D support for idea to check M600 command.

Good catch! Sometimes the simplest answer is the best. Often we look for more complicated reasons! The 'error' (not an error, it's doing what it's told to do) message should have been the clue...

Ian

@__noemy__ send M115 to see if it reports the DueX5. If the response doesn't mention it then check that the ribbon cable is connected properly and that power is applied to the DueX5.
