That is a common problem with the active bed leveling. Sometimes the brim prints perfectly fine, other times it comes out too thin in places. For example, I'm printing the same exact part now, one day after these pics were taken, and the brim is perfectly fine. Not super happy with the consistency of this printer...

Printing a part that should be fairly simple (?) for a 3D printer. Yet every print (most noticeable on straight walls) comes out with these uneven layer lines. This printer has been doing this since it was purchased and we've tried changing the surface the machine sits on (incase the table was too wobbly).The print bed is spring steel on a magnet adhered to the stock glass buildplate. Same issue occurs on the bare glass as well, over a variety of material types and brands. Any suggestions?

I've been trying for months now to print quite a tricky part out of CPE and CPE+ (boss's orders). However, the PVA supports I've been using just wont print well with the high temps required for these two materials. There's always oozing and stringing, which gets trapped between layers and compromises the structural integrity of the part. But equally frustrating is that the CPE just wont adhere to the PVA and warps like crazy. I was hoping to try using HIPS as an alternative to the PVA, since it has a much closer nozzle and build plate temp., but I cant seem to find anything on whether CPE and CPE+ can hold up to the limonene required to dissolve the HIPS. We haven't purchased the HIPS filament or solvent yet so I haven't been able to physically test it. Any advice or print suggestions?

Hello! As stated in the title, my company's UMS5 extruder 2 is printing the 1st layer much too close to the build plate even after active bed leveling. Extruder 1 prints fine, but once it switches to extruder 2, the build plate comes so close that little to no material is allowed to extrude, which in turn strips the filament so that the flow sensor has to stop the print on the 2nd layer. I am currently using a 3rd party build plate: Uncoated Spring steel (Printed Solid) on top of a magnet base (Printed Solid) adhered on top of the original Ultimaker Glass build plate. I understand that adding additional thickness to the stock buildplate is most likely what is causing this issue, however because I am printing CPE/CPE+ with PVA supports (extruders 1 and 2 respectively), the high build plate temp required to print CPE causes the PVA to over-adhere to the glass buildplate alone. I've already chipped both sides of the included glass plate trying to remove the stubborn PVA, which is why I went ahead and adhered the Printed Solid magnet to it and then ordered a replacement glass plate as back-up. (Bed Weld and the classic freezer-trick don't help.) Is there a way to adjust the settings in Cura or on the printer itself so that this 2nd extruder prints the 1st layer with the correct layer height? My current set-up is as follows: Extruder 1: - UM CPE - AA 0.4 Extruder 2: - UM PVA - BB 0.4 Build Plate: - Layer 1 | Uncoated Spring Steel (Flexplate Solution - Printed Solid) - Layer 2 | Magnetic Base (Flexplate Solution - Printed Solid) - Layer 3 | Glass Build Plate (Ultimaker, factory)
