[Off Topic] Layer missalignament….

peirof

hi,

this is the section of config.g, i am using:

[[language]]
; Drives
M569 P0 S1 ; Drive 0 goes forwards
M569 P1 S1 ; Drive 1 goes forwards
M569 P2 S1 ; Drive 2 goes forwards
M569 P3 S1 ; Drive 3 goes forwards
M350 E32 I0 ; Configure microstepping without interpolation
M350 X32 Y32 Z32 I1 ; Configure microstepping with interpolation
M92 X160 Y160 Z160 E890 ; Set steps per mm
M566 X800 Y800 Z800 E3000 ; Set maximum instantaneous speed changes (mm/min)
M203 X39960 Y39960 Z39960 E3000 ; Set maximum speeds (mm/min)
M201 X800 Y800 Z800 E1500 ; Set accelerations (mm/s^2)
M906 X1600 Y1600 Z1600 E1000 I30 ; Set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout

Some changes what can help? or Slicer changes?

thanks

Please confirm that the belts are not steel-cored.

No are steel cored, are the stocks GYm belts.

I have tightthe belts… At the maximum tension that i have can and slow print..and the same, layer not aligned.

I have a idea to probe tomorrow:

A downgrade belt tension. How many?
B some time ago, I change the voltage in config.g... Return to stock values
In TLM Duet Facebook group, in the last config.g in files section, in the section [MOTORS], the M906 gcode (M906 X1800 Y1800 Z1800 E1500 I30). One week ago i change this values for a recommendation.

What others test I can do?

Can you post a photo of a print that shows the layer shift?

You M203 XYZ settings are 39960 which is very high. Try reducing them to 18000 or 12000.

Hi,

… It is not easy share images, I am doing wrong... But

You were going to acquire a Zesty Nimble right?
If you are printing with one, make sure that the drive cable is not making your effector platform loose its position. The connection between the drive cable and the extruder needs to be relaxed. (not my words "relaxed and free arch to the stepper." by Zesty Nimble)

Hi,

Yes… But for the moment I don't have. I need print the adaptor....

dc42

I took the liberty of editing your post to display the images inline.

I don't see a layer shift in those prints, but I think the extruder steps/mm or extrusion factor may be a little high, and the nozzle temperature may be too high.

Thanks… Later try. Seems reasonably... It would be bad doctor

P. D. : What I have to do, for insert images in posts....??

To answer the question about displaying images:

Edit the Dropbox link to have raw=1 at the end

Hi,

After some changes, recommend by DC42, the print are much better, not perfect, but quasi…

What changes i have do?

Reduce temperature for ABS, to 215
Reduce extrusion multiplier... i know, i was using a PLA profile....
Reduce M92 E, to M92 E790

And the results, are much better:

Only one thing more, in the internal face, there are "bloops", in the face. Why can they be?

Thanks to DC42, for your help,i know is a off topic theme

And thanks to T3P3Tony, for photo tip…..
