Issues from the start.. but they made it right
Issues from the start... I pre-ordered the Snapmaker U1. I have other bambu printers as well as creality printers. Always disliked how much waist I had from my others as they were not tool changers. The snapmaker u1 seemed like a great entry without breaking the bank on a Bambu H2C with the Vortek hot end swapping system or similar system. When I received my Snapmaker u1 and set it up I had issues before I was even able to print my first print. The 4th toolhead was acting like it had residual filament and the light on the filament feed box was just showing red. Submitted a ticket for this issue and although they responded it was the usual response of did I take my brand new printer appart and check everything. I do maintenance for a living and I'm use to working on things but didn't expect to straight out of the box. Took the 4th toolhead completely appart. Never saw any residual filament or anything. However I went threw the full motions like the support tech recommended. I took everything completely appart inside of this toolhead and meticulously cleaned everything. It did work after this once I reassembled it and I've managed to get some good prints off of it when it actually works. I was impressed by the speed of the swapping and it definitely helps eliminate the waist issue of multi color prints without having to print multiple bed plates and glue models together or suffer from mountains of 3d pooping. But I have been having issues with the U1 and it seems to always be from the 4th toolhead. The very same one I've had issues with from the start. My latest print it broke the filament going into the 4th toolhead right as it was going into the top and to no surprise the filament detection sensor that was throwing a false filament detection right from the start didn't even realize it didn't have filament. It just kept ghost printing thinking it had filament. This of course ruined the entire bed of flexi suga gliders I was printing. I attach the 4th toolhead and heat it up and of course was able to feed the needle threw the nozzle without issue. Looks like I'm right back to taking this toolhead appart yet again and only managed to get 10 total prints without issues arising. Update: However this time around service team reached out to me. They ended up sending me new parts to fix the issue along with an extra spare. So I have changed my review from 1 star to 4 star. Much happier with the service and response from this second time dealing with the service department. Willing to update to five star once I see more reliability over a longer duration as the prints I have had from it turned out great and the lack of waist is great with the U1
