Hi,

I've more and more problem since the 2 last firmware update with layer shifting, it's happen where there is no particular difficulties.
I've considerably reduce jerk, acceleration and speed to see if it solve the problem but no.
I've also check mechanical parts, every things seem ok. I've installed a 40*40 mm fan under the duetboard, driver are "cold" and motor can be touch without burning your finger.
There is no blob on infill or perimeter…
It's also happen where there is no multiple print zone on one layer.

You can see on this print :

I don't know if it's related to pressure advance, i've relaunch a small print where i removed it.

Hope you can help me !

Thanks David for your quick and usefull reply !
I will do the basic, my skills are more limited in programming than I would do !
Thanks !

Hello,

Before I start to design a box for this optical encoder, I wanted to know if it has any chance to work with my duet 2 as a filament motion detector!
It have to be powered in 5v, maybe by the one from the 50 pin expansion. But I don't know if the 400ppr will be understand as signal is at 0.5v, does it work ?

Thanks !

Hi DC 42, Pilotltd,

Pitch is close to 2mm so like leadskew pitch, i will re-check all my bed dans redo test !

Thanks for your help !

@dc42

• Printer architecture : Core XY, Z driven by 3 leadscrews and 2mm pitch
• Microstepping set in the DUET in Z : 600 in leadshine driver : 1200 pulse/rev (i also tried other combinaison without success)
• Motor current rating 3.4A per phase and set 100% in closeloop and 70% in open loop

Motors are powered by a 48VDC down at 36V (if it helps)

Maybe i've an other clue to give you about this problem : when i tried to activate the bed leveling (after performed a G29) on a print, my printer going into "resonnance" Z motor is making an annoying noise, but don't go in alert mode and continue to move....

Hello DC42,

Yes the printer works correctly with thick layer (0.4 mm layer heigh) like this pic :

but when i want lower layer heigh, i get this wavy pattern (0.1mm heigh) :

If you've an idea of what can cause this, i would like to know !

Thanks !

Hello,

Does someone manage to use hybride servo drive (leadshine ESD 508) with their duetboard ?

I can not setup them to don't have wave on my print unless i use a 0.4 mm layer height...

Any advice ?

Ok my duetwifi board is a prototype, pin was not the same….

Hello,

I need your light to get my mini height sensor board work with my duetwifi…. When i power up my printer, the red led on mini board stay on and the value showed is 1000...

I've cheked cables, and continuity, and after few hours spended on wiki and forum i resquest your help !

Thanks for your future reply.

@Nuvag:

Would be interesting if someone could reproduce the problem with the attached .stl in the dropbox folder i posted?
I modeled several other test models which showed no or very minior problems, it looks like this only happens models with variable curves like the tooth in my model. I used an extruder jerk setting of 600 on all models i made photos of.

Looks like this problem also occured there:

With lower extruder jerk values his problem was much reduced, which is the same as i discovered.

Hi Nuvag,

I never get the solution, i'm sorry. Now i don't use pressure advance but i use kisslicer new version for a similar work.

Best regards,
Hugues

Great thanks !
