bad overhangs on one side of print
So for a while i have been having issues with overhangs on my core one..
its only really noticeable on one side of the print, where they start to "curl" up, which results in very uneven and ugly overhangs.
I always had the latest firmware and prusaslicer installed and used on mutliple files and orientation.
it seems like all overhangs which points to the front left, so away from the cooling fan, are the bad ones.
The problem also only started near summer when i first ntoiced it, but brushed off as the room being too hot. But since its autumn, it cant be that.
Also the firmware and slicer changed version once since this was happening.
I tried checking the cooling fan speed in my slicer but its set to 100% and on my core one to the default 40%
Im also printing polyterra pla, and esun pla and esun pla+.
color doesnt seem to make a difference
they start to "curl" up, which results in very uneven and ugly overhangs.
It is in he nature of additive overhangs to curl, the thermal contraction during cooling is the underlying cause. This may also cause head-crashes and consequent layer shifts.
With some parts just rotating the part on the print sheet is enough to move susceptible areas into a better orientation.
If this doesn't help save your project as a .3mf file
Files > Save Project as
Zip the .3mf and post it here. It will contain both your part and your settings for us to diagnose.
Cheerio,
RE:
yeah, that makes sense. I just dont understand why it didnt do that for 3 months or so..
I know saying it didnt do this before it did is kinda stupid but eh..
Anyway, i was thinking about a custom cooling fanduct. The only real problem is the clearance on the toolhead.
i know that valve released a model of the index's controller and headset and marked zones in which they could be modified ( https://github.com/ValveSoftware/IndexHardware/tree/master )
Maybe im going a wrong path here but if prusa has something similar to the core ones printhead, maybe a circular fanduct would help a bit...
