Hello everyone I have been using the Bambulab A1 with AMS lite for 2 weeks now. In the beginning everything was perfect I could print PLA and PETG without any problems. A few days ago the first layer stopped working properly and I am no longer successful. In my opinion, the first layer is much too close and is therefore rubbed onto the plate. I have already done “A1 Bed Tramming” as described in the wiki but it has not improved. Does anyone else have an idea of what is going wrong here? Software and firmware are up to date. I’ve already cleaned the disk with isopropanol, but that didn’t help either.
Edit: I can see in the video your extruder is clicking. Either there is not enough room between the hotend and the plate to extrude to the point that the extruder is clicking, maybe you have a smaller nozzle selected than you have installed or maybe you have some kind of partial clog?
I have my first layer too close and too much squish, I check the screws in the plate behind hot end but that didn’t solve my issue, is there a simple way to change the z offset for all prints?
I had the same issue after around 1500h of printing with my A1 - too tight first layer. I tried a few things like cleaning nozzle tip, cold pull to clean it from inside. Then, following the advice here, I checked the screws, and indeed, one screw was missing and other three quite loose:
After tightening the remaining three and reassembling the first layer turned out just perfect. I’ll do the same maintenance to my second, a bit older A1 which has 2500h and doesn’t show the signs of this first layer issue. Thanks for the tip.
I having trouble while printing in a1.
It prints perfect but starting each layer add a small extra at the starting. And this small extra is added in all layers. What should i do
