Firmware 1.19RC1 released - please help us with testing!

Forgvn77

I have a delta diamond hot end mixer. Not sure why, but when I go to change tools on the fly while printing, the method of the printer tool change appears completely random. Sometimes it just stops and starts various filaments without retraction. Sometimes it will stop all filaments and retract/extract the activated ones very aggressively. And just now, all it did was retract the activated filament about 10mm and extruded nothing for several seconds. Not sure what's going on, but it'll need to be fixed of course.

Can you post your config.g file and the Gcode file to a file sharing site, and link to them?

Apart from the messages, are there any problems with the print?

dc42

Do you have any tools that are configured with just one extruder drive instead of all 3?

Is your file sliced with absolute or relative extrusion?

Forgvn77

Okay, here's a link to the g-code generated by Slicer Prusa Edition:

Here's a link to my config.g:
https://1drv.ms/u/s!Aj8zwnOgeBYCwTPerlixbih-PG8f

To answer your questions:

No, the print appears to be okay and the messages are generated during but not stopping it.
No, I don't have any tools that are configured with just one extruder drive instead of all 3.
It appears that it is using absolute extrusion distances.

Thanks,
John

Thanks, I'll simulate that print tomorrow. In the meantime you may wish to downgrade to main firmware version 1.19beta11 and keep everything else the same. I don't think it will show either of those issues, but shout if it does.

Forgvn77

I did have the tool change issues in 1.19beta11 and they are the same as far as I can tell. The g-code message though only appeared in this release.

dc42

I've found and fixed what's causing the error messages. One is generated every time the firmware processes a G92 E0 command. They are harmless provided that the E parameter is zero.

dc42

When you say " when I go to change tools on the fly while printing", do you mean that you are sending T commands from the console while the machine is printing - or perhaps you are editing them into the gcode file? If so, I know exactly what's happening, and here are two different workarounds:

1. Slice the file using relative extrusion instead of absolute.

2. Instead of changing tool, just change the mix ratio of the current tool using M567. This has the advantage that the print won't stop and start.

If on the other hand the T commands are ones inserted into the file by slic3r, then this is a problem that I need to investigate.

Im getting random resets of the duet, running 1.19 RC1, wifiserver beta 10, its happening when I home all (to mech endstops, it crashes after it homes z).

EDIT - it seems to be doing it when I run this macro after homing.

I tried running the individual commands, it crashes after initiating the first G1 command.

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.

Forgvn77

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?

dc42

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.

DjDemonD

Thanks David, I'll try not loading the grid in config.g but load it in start gcode instead.

dc42

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

dc42

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.
