Overhanging issues
Hi,
I recently changed the nozzle to a Bondtech CHT .4mm. In general the print quality is fine after some adjustments. As long as the walls go straight upwards. Unfortunately, I do have some major issues with overhangs I cannot explain. I printed a benchy with .2mm layer height and not too fast (100mm/s) in my opinion. The result was terrible.
My hotend is a ZODIAC x Phaetus BMO with a Sherpa Mini extruder.
Also I had to find some issues while adjusting layer advance and printing the tower. There the layer height is set to .3mm as requested and this leads to bad layer adhesion due to... under extrusion?
I tried PLA (205/65) as well as PETG (235/85), both behave same.
Any Ideas what to check?

LMK if/when you find out cuz my benchy looks like this

Well, I will but at the moment it even goes weirder. Yesterday I switched to a more standard hardened steel nozzle and the results are the same. Warps like hell too.
Never had this problem before. Printing temperatures are the same, cooling at 75% as before.

@petjek68 did you solve this issue? and if, how?

Does your part cooling fan spin up?

The curling on the front of the benchy is usually caused by insufficient cooling. The gaps on the PA tower doesn’t look like a cooling issue.
Did you recalibrate your extrusion multiplier? It’s possible the different nozzle changed the flow.
Whoa, didn’t realize the OP was so old.
Maybe start a new forum thread for your issue.

i don't have that problem - i just wanted to know if he solved that. Both out of curiosity, but also so others that have the same problem will maybe find a solution here.
my benchy looks like this with a 4028 fan
crazy amount of cooling imo
