Problem with Support
Hi,
i hope someone can help me with my problem.
First my data:
Printer: Mk3 preassabled
Firmware: 3.3.0
Software: Win 1.40.0
So now the problem:
I have a print with support:
When i start to print this model i get this bad first layer result:
Here the settings:
The same with the 0.15 Settings.
What is the problem? 🙁
Re: Problem with Support
Is your nozzle free of debris, and did you clean bed with isopropyl alcohol?
Re: Problem with Support
Looks like you need to adjust your Z height. See pages 24-26 of the manual.

Re: Problem with Support
In addition to the 1st layer, SLOW IT DOWN. I find that detailed dense support is really touchy, and any sort of disruption will result in it peeling off the bed. To test, when your print starts, simply dial speeds back using the front knob. I'd suggest go back to 50% and see if the filament starts laying down consistently. Once it does, you can start adjusting speeds upwards.

Yes i clean the bed every time bevor a print with 99,9% isopropyl.
The nozzle is also free of debris:

I bought the printer fully assembled. So i hope the calibration must be fine!?

Ok i will test it maybe with 35% and give you a feedback 🙂

Ok in the first minutes the result looks better. bevor i scaled down to 70% and it was the same problem... now i tryed with 35% and the result looks like this:
Re: Problem with Support
Even if the printer is pre-assembled, you really should to Live-Z adjustment. It can vary depending on filament type and any nozzle changes or other adjustments you've made.

Recalibration is necessary even after moving the printer carefully, for instance in your own car. I doubt the factory calibration is going to survive transport by parcel carrier.
Re: Problem with Support
Thank you for all your help.
Another problem solves my issues with the support.
It was the same issue like this one: https://shop.prusa3d.com/forum/assembly-and-first-prints-troubleshooting-f62/first-layer-frustrations-t19004-s20.html
So the Topic can be closed 😉
