Has anyone else noticed the titles issue? It seems like this happens a lot, and it’s quite infuriating. It also causes blobbing on the prime tower, and IMO, significantly increases the chances of prime tower failure. A video is attached. It doesn’t do it on the right to left, only the left to right.
I understand we recently had a different prime tower issue that was addressed, but this has been going on for a long time, and I have noticed it on others prime towers as well… I don’t recall ever seeing a thread about it though.
My prime towers look like a rock star. On EACH nozzle change I get so much oozing that I get about 20-30mm of filament hanging from the tower. It’s so bad it bent my ooze stopper thingy , and made it crash in the wipers the next time it purged. I even noticed the left oozing while using ONLY the right… also the temperatures seem to always be too high or something, my purge poops and lines are caked , and I’m sure it’s not foaming due to moisture, I’ve noticed this happen with both freshly dried filaments and stored ones , abs, petg, petg hf, gf and cf alternatives, even pla.
Yea I just don’t understand why it’s trying to extrude before over the prime tower… Isn’t that literally the point of it? To rebuild pressure in the nozzle before printing?
It has to extrude over somewhere, but most importantly, it has to heat up. It’s unavoidable during the heat up process the nozzle oozes (if no retraction is applied)
If you pay a close look over your tower you would notice that the nozzle is doing a dance around the tower right before it starts to actually print on the tower. It dances around to avoid attaching the ooze onto the rest of the wall, before entering through a tiny gap. This gap is where the tower is designed to absorb and clean up that ooze
Yeah yeah. But that started with the last update. and 1-2 mm would be normal yes. Whole centimeters of strands of oozed filament is not normal, especially when it’s so much it pushes the flap out of the way.
Der Prime Tower ist eine absolute katastrophe die blobs auf dem tower die durch den düsen wechsel entstehen machen ihn so instabil das er ab einer gewissen größe umfällt weil die druckbett haftung nicht ausreicht hab dadurch schon diverse drucke verloren
Or, hear me out here…I know it sounds crazy and all, just use the traditional wipe tower and use the nozzle wiper for…wiping? Dunno kinda runs in the name ?
If you watch the extruder switch, it is unretracting far more than it retracted before the switch, which then overextrudes before it moves back to the tower.
I have the same problem. It can only be improved by lowering the nozzle temperature and manually adjusting the filament retraction settings, but it cannot be solved. I think the H2D has too long a waiting time after changing the filament; this is particularly prominent when using sup Petg.
Has anyone resolved this issue? I have been unable to fix it and support tickets were not helpful. I was basically just told that they do not help with custom filament profiles. I’ve experienced this issue since preorder and have not been able to figure out a fix with custom profiles. Any help would be appreciated
