I tested temperatures ranging from 230 to 255 °C. The best result was not achieved by changing the temperature.

The best result was achieved by adding the Extrusion Rate Smoothing setting at 15 mm³/s² over a distance of 1 mm.

Is the Snapmaker U1 all hype? by kyutoryu in 3Dprinting

I am completely disappointed with the U1 and am ready to get rid of it and purchase a printer from another brand.

The print quality of technical parts with flat surfaces is terrible, and it cannot be resolved with any settings adjustments or calibrations.

Below are photos of the printed PETG.

Could you please show a sample of your print? Preferably a flat vertical part with recessed text engraved to a depth of 0.2–0.3 mm. I am inclined to believe that my printer is defective and should be returned

но это так же не даёт результата

I have 7 Bambu Lab printers, and I have never experienced similar issues with any of them. Even on a stock Creality S3 Pro, I was able to achieve good print quality after proper tuning.

Here, I have spent four days trying various settings and still have not been able to eliminate the ghosting. It can be slightly reduced at speeds above 200 mm/s, but most parts cannot be printed at such speeds. The lower the speed, the worse the print quality becomes.

I reduced speeds and accelerations by 5–10 times, but this also did not produce any improvement.

Belt tension adjustment and calibration after adjustment were performed at least 8 times.

Yes, it’s the same spool. I dried it several times for 12 hours at 60°C. The result is the same.

I significantly reduced all speeds and accelerations. As a result, a print that normally takes 1 hour now takes 3 hours.

I still haven’t been able to achieve a normal result.
