Hello. Im a little late to the party but wanted to share my feeling about my B1. To start off i have an artillary x1, a wanhao i3mini, some unkown DPX thing and now this B1. I had purchased the tronxy xy-2 pro but it was a total peice are garbage in my opinion. Other people has had success and thats fine for them. Soo i got the B1 to replace the tronxy as my mid sized daily machine. After arrival and setup ive had many issues with my B1. It started with the gantry arms not beeing spaced equally so i had to flex the chassis to get them to line up. Then the drive gear on the x axis was machined off center so it lobed around creating tension issues. Then i got it together and did a few small tests and it seemed ok. But the bed was always high in center and not flat. once i sliced my own file i was having x axis shutdowns, filament extrusion error messages. The filament would unload itself after prints. I tried firmware backdates and updates and custom firmware and every step gave new issues.
Now im waiting on a reply from BIQU about what to do next. It makes me sad becouse BTT makes awesome stuff so how did this go so badly.
On the good side. When i got it to print successfully the print quality was great. Nice smooth z axis surfaces, very little strigning even with PETG, great interface. I really want to love it!
