@user3d the R parameter is the allowable tolerance on the measurement.
You need to adjust the calibration (mm/rev) using the L parameter. From the looks of things, you set it to 7mm/pulse and it thinks it should be about 0.9mm/pulse.

@user3d said in Gaps in wall while printing:

@dc42 Any suggestions to resolve this backlash problem in preloaded ball screw system.

Are there grub screws involved in coupling the ball screws to the motors?

You have a huge amount of backlash in the direction bottom left/top right in the first and last images you posted. How does that direction line up with the axes of your printer?

You may want to keep an eye on this thread, it sounds like it may be a similar problem: https://forum.duet3d.com/topic/24694/3-4-0beta2-printer-stop-mid-print-with-no-reason-errors

@user3d 3.4beta1 has been superseded by 3.4beta2. The EXP1XD firmware is at https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.0beta2-not-Maestro. The 3.3 stable release of the 1XD firmware should also be compatible with 3.4beta1 and 3.4beta2.

@chrishamm Thanks for the help!

@dc42 Thank you!

@user3d try shielded wires?

Most unusual...

Can you please share your config.g and the results of sending M122 and M98 P"config.g" in the gcode console?

When you say it follows the extruder motor and not the driver, that makes me think it's the motor wiring either external or internal to the motor itself, however, you also say it happens with both extruder motors depending on which is being used at the time.

Can you share some photos of the extruders and the wiring? Maybe there's something odd going on.

Are you able to re-crimp the extruder motors connectors?

@droftarts ok now i understand why i saw it on the release notes but not on the release.

@user3d
I've made fan shrouds from color-changing PLA, just to see if there is any difference in fan-direction.
The color changes from orange to yellow above 33°C

I could see changes with different filament temps, but not related to fan direction.

@neodue I'll take a look tomorrow and see if I can duplicate.

@dc42 Yo, It worked! Thank you : )
P.S. : I also had to copy bin of GNU ARM in GNU TOOL's bin as gnu arm eclipse was installed in program files due is 64 bits and gnu tools arm in program files x86 due is 32 bits.

@dc42 said in Error count | M122 ?:

Does the Ethernet connection run reliably, or not?

yes I suppose. DWC works fine!

Do you just get one txerror when you first connect?

I get it all the time... after connecting , during print , after print finishes .
If it is so because of unreliable Ethernet connection then how do i verify that?

That's a good question, but I'm not sure how to answer it. Unfortunately the creator of that project, Danal, passed away almost a year ago. So I'm not sure if there is anyone that could answer that.

@dc42 said in Current speed greater than Max speed?:

What was the move that you are executed?
G1 X290 Y290 G1 X0 Y0

If it's a Cartesian machine, then as both X and Y can move at 5100mm/min simultaneously, the combined speed of a diagonal move can be higher, up to 5100 * sqrt(2) for a move at 45 degrees.

Got it. This is happening on diagonal moves only. Thank you.

Got it!
Thank you @Phaedrux @fcwilt

@droftarts Thank you : )

@fcwilt I started doing so after nozzle ran into my bed and scratched it
