Firmware 1.19RC1 released - please help us with testing!
-
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.
-
Just tested with head 0 offset of -10 and G1 Z commands after tool change, that everything seems to be working, apart from the head crash. Cool.
-
Kulitorum, thanks.
Lars and Kulitorum, I've just released RC3 with fixes for (I hope) CoreXY homing and IDEX tool change. Please try it (carefully - I suggest you reduce motor currents at first).
-
Thanks. Just tried it, and on the first change to T1, this happens:
T0 is moved away correctly.
T1 should move to R2, (R1?) but it tries to move the wrong direction, and just slams the head left.I let T1 print (outside the printbed) and when it was done it slammed left again. Then T0 did its thing correctly.
Then T0 parked, and T1 printed correctly. (although offset 2mm left because of the headcrashes) -
After T0 layer2:

Thanks again for the videos. Is the +X direction to the left on your printer?
-
Still problem with RC3. I move X and U and it works (T0 is active tool after boot). I change to T1 (right tool) and when doing a X+1 (or was it X-1) it stats to move towards the right side. I managed to emergency stop before crash as lowered both max speed and current. This is unhomed so no tool change scrips should run but as you requested them I'll include them below, I only have tfree0.g and tfree1.g.
Homing worked better this time but first time I ran it the right (t1) carriage never move out to the end stop. I could not reproduce this but I believe I have seen it once before (in earlier betas), that time it was t0. Second homing worked as it should. I restarted the duet and homed again and it worked.

Any progress? - Eager to start testing

I really appreciate your help, because I need to resolve this today ready for the release tomorrow.
I'm puzzled because I just ran some more tests and I can't replicate your issue using RC3. Please can you try the following:
1. Home all axes. I homed X, Y and U in that order, and then sent G92 Z0 because I don't have a Z probe on my test rig.
2. Either send M302 P1 to enable cold extrusion or heat the hot ends up so that the tool change macros don't generate error messages.
3. Send the following sequence of commands:
T0
G1 X100 ; X carriage moves to 100
T1 ; X carriage moves to near home position
G1 X200 ; U carriage moves to 200
T0 ; U carriage moves to near home position
G1 X100 ; X carriage moves to 100If this goes wrong, please let me know where and/or post a video. If it doesn't go wrong, please try to find a simple sequence that does.

David, have you tried relative moves? I remember last time I tracked down this kind of problem (after beta 6?) it was related to relative moves… How does the web interface issue its moves, relative or absolute?
-
Your little test script runs perfectly.
The small script here makes some wierd movements, so I am trying to figure out when and why.
The documentation for M111 is a bit shallow, can you tell me how to get realtime echo of the command running? (Or better, extend the documentation, but I guess that's not today)

Interesting, I did the test you asked for and it worked as expected. I then switched to T1, changed to relative G91 and did a G1 X-1.
This moved T1 from end pos (529.4) to 99…12:31:58 G1 X-1
