Topic: Mystical layer shifting?!

Hi guys,

I had my Solidoodle 4 for about 2 years, and after i made a bunch of upgrades and got it calibrated, it have really ben printed flawless.

That is until yesterday, where i wanted to print a low-poly dragon in 300%. I have attaches a picture of the print, and to me it looks like it layer shifted in two axis at the same time?! I checked the gcode and it looks perfect.

Its really weird because i haven't had any trouble with the 3 prints i did today, and i have never had layer shifting before. Any ideas?

- Jesper

Re: Mystical layer shifting?!

What have you checked in your troubleshooting so far?  Have you modded your XY-axes?

For the record: https://www.simplify3d.com/support/prin … salignment

SD2 Sanguinololu 1.3a atmega1284p, wood platform, lawsy's carriages, braided fishing line, pallet wood overhead spool mount, carboard/magnet enclosure, glass bed, E3D v6, bed levelling knobs, extended z-stop, 25A DC-DC SSR for bed heater, everything fixed to the SD2 frame, marlin firmware with some adjustments and extra failsafes enabled.  I'll never give up on you, little printer that could(n't)!

Re: Mystical layer shifting?!

Looks like the culprit is layer delamination.
As the lower layers cool, the perimeters are shrinking and pulled by the infill. This is more common with bad filament, though possible with good.
What material are you using? If ABS, if the build chamber is not warm enough, delamination will occur even if you have good filament.

Re: Mystical layer shifting?!

I am trying out some really shitty ABS (ESUN from hobbyking). I have never had smell or delimitation issues with ABS before but this one can only be printed in ventilated areas and it is very prone to interlayer delaminate.

As for this issue im pretty sure it is layer shifting and not a complete layer seperation. The printhead was printing beside the layer it should be printing on and the layers was still connected when i canceled the print. I know there is, what looks like, a pretty clean delimination on the picture, but that is really just me trying to investigate and breaking the piece while doing that.

I have now printed 10 prints after that one and all have been great, so im kind of thinking it must be somerheated stepperdrivers because of the big print? Have anyone observed something like this?

I have definitely had motor skipping due to overheating stepper drivers.  I now have a fan on my board which helps, plus I'm installing little heatsinks for each stepper driver today.  Z-lift can overstress stepper drivers, if you have that on try turning it off.

I will wait to see if i get a shift again and if i do i will try to make som kind of cooling.

thats exacly what mine did too when over working steppers and no cooling fan on MB. also like Azerate said. ABS when doing large prints over an hour MUST have inclosed build area and stay warm. as for smeel ABS always smells and is toxic thats why I use a cheap charcoal filtered exuast fan from Walmart Holmes brand $15 get extra charcoal trimmable filter material too and replace every 3 months at least. wont eleminate odors 100% unless vented outside but helps with toxic part

Solidoodle 2 with Deluxe kit cover & glass bed with heater. and 2nd board SD2 used not 3rd and alum platform not installed yet still wood. also need cooling fan installed to board. use Repetier Host couple vers. Slic3r also have all free ware STL programs
