Firmware 1.19RC1 released - please help us with testing!
-
DJDemonD, thanks for your report. The diagnostic info that indicates that the Move module was trying to print some debug info to USB but you didn't have a USB connection to a PC. The Move module only prints debug into when you send a M111 S1 command to enable debugging. Is it possible that you did that?
If you don't think you did, please connect a USB cable and attach to the Duet using pronterface or similar, and see what it is trying to print.

Looks like CoreXYU is broken in RC1, I installed RC1 and tried to home all. Second carriage started to move jerkely in the wrong direction like steppers were moving the wrong way out of synch. Reinstalled beta 11 and everything worked again.
-
I turned on "Relative E distances" in Slicer Prusa Edition, resliced, and reprinted. Tool (filament) changes appear to work correctly now and without issue. The g-code error messages I was getting before have stopped as well. The Slicer setting was the only thing I changed.
Thanks for your help!

It produced this output just after a homeall

Also and it may be entirely unrelated to RC1 my grid compensation setup is:
M557 X0:260 Y0:190 S50 ;define mesh
M376 H10 ;taper off after 10mm
But it only moves 20mm between probing points (same on beta11) are 20x20 the largest grid squares it will probe? -
20mm is the default, but it can use more, and I have just tested it. I suspect that your M557 command isn't working for some reason, e.g. because you have subsequently used G29 S1 to load a previous height map that used 20mm spacing.
You can run M557 with no parameters to see what the current grid is.
-
Thanks David, I'll try not loading the grid in config.g but load it in start gcode instead.

I've just released 1.19RC2:
- Changed the way we handle tool offsets during a tool change to (I hope) better meet the needs of both IDEX and conventional dual-nozzle printers
- Fixed spurious error message when G92 E0 is processed (this affected users who used absolute extrusion coordinates when slicing)
- Fixed Duet3D filament sensor data receive code
-
CoreXYU still broken in RC2. This time I tried first X than U with no problem. Then changed to second tool and did a X-1 in the interface. This crashed the second tool into the rail at max X/U…
Edit: I did not dare try a home all
-
Hi Lars, thanks for trying RC2. However, as I have neither an IDEX machine nor a CoreXY machine to test on, I need more data:
1. When you changed to a second tool, where on the X/U axis were the two carriages?
2. Please publish your homing files so that I can simulate them as best I can.
3. Please run some more tests. You can help protect the mechanics of your machine by reducing motors currents, as well as having a hand on the power switch.
Try homing X, Y, U and Z individually. When you have found one that doesn't work, run the commands in that homing file individually, then you can tell me which command is giving the problem.
Thanks - David
-
Lars, I think it might be something peculiar with CoreXYU and tools on RC2 as well. I have tested tool changing on a Cartesian IDEX and it appears to work correctly. Can you also publish your tool change macros pls.
-
Hi Lars, I think I just found the problem with homing Core kinematics, so no need for those tests now.
-
IDEX still dont work.
The z offset is still not used on the printheads, while it is still displayed correctly in the interface. - in the video, the purple toolhead should have been printing 10mm over the bed.
Worse, the heads craches on second toolchange.Config files:

-
Thanks Kulitorum, that's helpful. Which tool is printing which colour? I'm guessing that T0 is black and T1 is purple so that the second tool change is T1->T0, but maybe you have it the other way round?
-
Hmm, I just realized that after the second toolchange, as the heads craches, it is actually printing at z10….
But the z offset of 10mm is defined for tool 1 (left tool) and is used for tool 0 (right tool) but only on the second usage of that tool.
-
You are right - tool 0 is the right tool, black filament, tool 1 is the left tool, purple filament.
-
And here's the gcode for the print - for reference:
-
Thanks. I think the Z offset is working correctly. You have specified a Z offset of +10mm for tool 1, which means that tool 1 nozzle is 10mm higher than the reference point. So it should be trying to print 10mm below the bed surface; but you probably have a limit set at 0mm. If you want the tool to print 10mm above the bed, you need to specify a tool Z offset of -10mm in your G10 command.
Using your configuration, I have replicated the problem of the U axis moving when you re-select tool 0 and move the head in X, and I am investigating it.
-
Ok, cool. If this is correct, then why is tool 0 printing at z10 for the last 5 secs if my video?
-
That would because when tool 1 was selected, moving to Z offset 0+first layer height was prohibited, so it moved to 10mm + first layer height. Then when you reselected tool 0, Z was at 10 + layer heights and now G1 Z command has been read in the gcode file yet.
