3.4.0beta2 - delta printer prints crooked in y-direction

[CaiJonas]

Hello together,

when I use 3.4.0beta2 my delta printer prints crooked in y-direction along the z-progress.

I do not have this problem with 3.3 stable.

Any suggestion for this problem?

here is my config:
c4d1f6bb-1c8a-49f5-b2a5-d04a6a8038fa-config.g

Best Regards,
Cai

[CaiJonas]

Have this problem also with Software bundle 3.4.0 beta 3.

Any Ideas?

@caijonas please run a few layers of that print and then send M122. Look for "step errors" under the heading Main DDA Ring. If the figure is nonzero, then please connect a laptop running YAT or another terminal emulator to the Duet via USB, and send:

M111 S1 P4

This will enable Move debugging. Then continue the print and watch out for debug info on the laptop. anticipate that you will see one or more blocks of debug data per layer. When you have collected a few, please post them here along with your config.g file and the GCode file you are printing.

@dc42 I also get this issue on 3.4b2 on the STM32 port.
Unfortunately nothing shows up in an M122

@jay_s_uk @CaiJonas please can you both post/make available your config.g file (and any macros that it calls) and the GCode file the exhibits the problem.

The left is 3.4b2 and the right is 3.3.0

[dc42]

@jay_s_uk I printed your file on my Duet WiFi powered delta, and it came out straight.

@CaiJonas which Duet are you running 3.4beta3 on? Please share the GCode file.

[gloomyandy]

@dc42 Was that using beta2 or beta3?

[dc42]

@gloomyandy said in 3.4.0beta2 - delta printer prints crooked in y-direction:

@dc42 Was that using beta2 or beta3?

Beta3.

[gloomyandy]

@dc42 Thanks, I should have a build for jay to try of beta3 shortly, just testing it at the moment.

[T3P3Tony]

@jay_s_uk are you still having this issue with the 3.4b3 build the @gloomyandy did for you?

@CaiJonas which Duet are you using and can you share the gcode that causes the issue. please

I have tested this using 3.4b3 and do not get a leaning issue.

[jay_s_uk]

@t3p3tony yes, I am.

The left one is 3.4b3 and the right one is 3.3.0
Only change is the firmware version

[T3P3Tony]

@jay_s_uk can you post your config please. Also if possible try a simple hollow cube to see if that also displays the issue please.
