FANTASTIC when everything's working right!
After waiting for what seemed like forever. I received my U1 in December of 2025 I was very excited. Unboxing and setup was easy because of the fantastic setup manual. I was all set to print within 40 minutes. With the initial calibrations completed I started to print the little dragon. It turned out unbelievably well. I was very impressed. Then I tried to print a file that i downloaded. Not impressed! It would not print as anomaly after anomaly kept showing up. X axis out of range, Y axis out of range, and others. I did everything to correct the errors that I could find. Then I contacted support and sent them some files and unfortunately I had to leave my 3D Printer to go on a holiday...when I returned there were updates of the firmware, software and App, which seemed to solve the errors that I was having, untill the next update and then anomalies started to happen again. I again did everything that the Snapmaker Wiki said to do with no positve results. Contacted support again and sent files of what I was trying to print. Lenard from support sent me the updated Snapmaker U1 system files and after I had them installed everything work again. I believe that the system files must have been corrupted from all the install and uninstall and updates that I did. Had a problem with my U1 right 3/4 feeder in that the #3 toolhead kept showing a tangled filament or broken filament even though it was not. Contacted support after doing all the Wiki steps and was asked to change the 1/2 feeder with the 3/4 feeder to see if the problem followed the feeders, which it did not. Support sent a new feeder and in 6 days I received the new feeder and was up and printing again. I changed the angle of the touch screen with a mod but when taking off the screen I cut the ribbon cable. Ordered two new screens at a very reasonable price from Snapmaker and four days later I was printing again. Snapmaker Support is the best support team that I have ever dealt with! This is the second 3D printer that I have owned, the first is a Creality K1 and I have to say that the U1 is FANTASTIC when everything's working right. I also like the monthly updates, shows that the team is striving to get things right for the customers.
