Hello everyone.
I need a help about this problem.
These days I am experiencing issues with the purge tower when printing 4-color figures on my Snapmaker U1. During long prints (12 hours or more), once the process reaches the 90% mark, the problem shown in the photo occurs. Inevitably, the tower ends up collapsing…
I have a filament dryer and and I der filaments before printing.
My print settings are as follows:
Layer height: 0.14 mm
Nozzle temperature: 225°C
Bed temperature: 60°C
Flow ratio: 0.98
Outer wall speed: 90 mm/s
Inner wall speed: 130 mm/s
Nozzle diameter: 0.4 mm
Filament: PLA
I’ve seen that problem too. I don’t know what the answer is, clearly the wipe tower is doing its job and cleaning a blob off the nozzle, but then the blob makes the tower fail.
If that were an actual print, there would be sparse infill and therefore somewhere for the blob to go.
what settings are you currently using for your prime tower please, also which slicer?
Fair enough, but once the tower collapses, the pressing process remains incomplete. It hasn’t finished its job as long as the pressing isn’t done.
That’s way too high for PLA.
That’s not true. I print all of my PLA at 220 and 225 is still within a reasonable range.
Hi, have you tried to reach out to the technical support(https://snapmaker.formcrafts.com/u1-troubleshooting-request)?
If possible, it’s also recommended to send your .3mf file to technical support so our engineers can try reproducing the issue.
Best regards.
Thanks.
I’ll try this…
Let’s say it’s too hot.
What is the normal temperature for u?
These are my settings for PLA, and I use the blue build plate from BQ.
Bed temperature: first layer 55°C, all other layers 40–45°C
Nozzle (steel): first layer 220°C, all other layers usually 210°C
The exhaust fan runs at 30%, and the door is just slightly ajar.
My print speed is also kept moderate since I don’t want to print fast — the models come out better this way. That’s something everyone has to decide for themselves.
Nothing overheats on my end, and all my prints look like I made them on my Bambulab.
Thnx man. I’ll see…
It’s been a while I didn’t have a multicolor print on U1. Last night I tried 215 °C with (Esun PLA Basic filament) Generic PLA setup. After 10 hours of print, top of the purge tower was good. And also, it didn’t collapse. Thank you.
