Layer shifting
-
Hi,
I put this question here because I have no idea what is due, I explain the problem:
- Delta printer
- PETG
- Printing speed 45 mm / s
- Temperatures: 240/75
- Layer height: 0.15 mm
The problem occurs after the first layers, never at the same height, many times, only occurs once in the entire model, sometimes occurs, 2 or 3 times.
What happens is that the layers move, maybe 1 mm, at most 2, the first few times I pass, I thought it was because the straps of the towers were not tense, and I tensed, the same thing happened to me again . Then I thought they were very tense ... and loosen them, but nothing. The same.
The only thing that occurs to me at some point, the engine of a tower loses steps ... but is there any way to check this?
I am using thiese currents in config.g:
M906 X1200 Y1200 Z1200 E800 I40
How do you see them?
Two main doubts:
How can I check if some engine is losing steps?
What are the recommended currents for Nema 17 motors?P.D .: I take this post to congratulate Christmas to all .... Even David. XD.
MERRY CHRISTMAS!!!!!!!!!!!!.
Let's see if Santa Klaus brings you an OLSSON RUBY -
You could configure stall detection to report any stalls.
Current should be set around 85% of the motors rated max current.
Is the plastic curling and getting caught on the nozzle? Maybe you need to add some Z hop.
-
Which Duet are you using, and what is the specification of the motors?
-
Its a Duet 2 board with 2.02RC7(RTOS) (2018-12-22b2) firmware... And until tomorrow i hace no acces ti motors, are stocks motors, Nena 17 of 1.8 degrees
-
there are many different nema 17 motors. each with their own current rating.
also is it a duet wifi/ethernet/maestro.are you using 12v or 24v?
-
Duet 2 wifi and 24v

@peirof Since you're using PETG, is the nozzle leaving blobs behind? The blobs left behind would cause skips when they got left behind and when I upgraded to the silicon socks on my e3dv6, the blobs disappeared.

Maybe.... i have blobs with PETG....
I will try
