tool change - y slide?!?!
-
hey community
I have the problem, that y is moving in + direction in regularly moves.
That only happens when changing tools while printing. BUT NOT when changing tools just (when nothing is printed) --> I changed more than 100 times when not printing. Everything fine....A few weeks ago, I have been printing with tool change for weeks without problems.
With printing after a few layers the coupler has moved so far Y+ (see picuture) that the TC doesn´t fit anymore to collect a new tool. See picture.
I already tried_
- different cura version
- update duet 3 and boards
- it´s definetly not a physical problem
Is there somebody who has/had the same problem?
---very happy for any suggestionens.

@gruna-studio please post the bit of gcode in a print that recreates this
-
I can only upload 4mb to the forum. the file has 10mb....
-
@gruna-studio it looked like it happened at a particular point in the file, can you cut down the file to just after the issue occurred (worked out from the Z height or layer)
-
@t3p3tony I am working with gruna-studio to investigate the issue. To test some stuff I made a short script that does about 10 changes back and forth with some moves inbetween. This was confirmed to cause the issue as well.
MoveTC10_test.gcodeTo furter elaborate on the issue. Toolchanges seem to cause a growing y-offset, eventually leading to the toolchanger failing to pickup a tool and leaning prints. IIRC, a re-home of the axis resolves the issue. Also manually changing tools (selecting in DWC) many times does not seem to reproduce the issue.

@nxt-1 @gruna-studio
Thanks for the file, I have looked at the file and it appears to include bits of tpostN.g files which is a bit confusing, are those just comments left over from some other testing or something else?
Also I see a G1 D1 and G1 D0 commands what are the "D"s aiming to do?
Please can you upload your tool change macros for tool 0 and tool 1 for reference.
-
@t3p3tony I noticed the D's as well and the fact that that parameter is not documented on the wiki. The reason I left it in there is because I copied/modified a g-code script (created by cura) I got from OP. I believe they are silently ignored by the Duet.
After some more testing we can confirm that just tool changes work. MoveTC10_test_2.gcode contains basically only toolchanges and that was reported working without issue.
So I figured somewhere between script 2 and script 1 lies an issue in the g-code commands.
My next step was to slowly remove more and more gcode starting from script 1 and see at what point it started working.
MoveTC10_test_3.gcode -> not working
MoveTC10_test_4.gcode -> not working
MoveTC10_test_5.gcode -> not working
MoveTC10_test_6.gcode -> reported not working but slower. Only after 1,5 runs of the script did the offset become to large for a tool change to fail. (normally failure is reported after ~8 changes)EDIT: At this point I don't really know how to advice/test anyfurter. Since we can almost certainly rule out mechanical issues, since script 2 works without issue. But anything more that just tool changes does give issue ¯_(ツ)_/¯
