  1. Yes, but not a satisfactory one. I've discovered that the problem only arises when I print with a .2mm layer height. The issue doesn't occur with .15mm. Also, part geometry plays a large role and I'm not sure why. Curved surfaces on SOME of my parts come out like this at 0.2mm layer height, but not on others. It's really been a trial and error issue.

  2. eSun PLA+ is my main filament I use on both my S5 printers and all I have done is use the main PLA profile and just made the temps 215c and it prints fine.

  3. thanks anthrix for your findings! to take things a little bit further, i did some work lately on this particular topic, and these are my findings so far: 1. have some freewheeling diodes added to the PWM outputs of the SKR V1.4 to avoid overvoltage damage to the output MOSFETs: bigtreetech-skr-v1-4-turbo-freewheeling-diodes 2. also, do _not_ use smoothing capactors on PWM outputs. this is simply bad practice that puts a lot of extra stress on the MOSFETs. instead, use proper PWM settings in your MARLIN configuration. 3. TMC5160 drivers should have stealthchop enabled, but _disabled_ through the printer's config menu. this reduces noise of the steppers. 4. it took me quite some time to figure out the basic settings in MARLIN 2.0.5.3 to make it cooperate with the skr1.4 and the UM2+. besides that, you need some extra hardware to properly connect the PT100 sensors and the hotend-fan to the board. see more details on my github: Marlin+SKR1.4+TMC5160+UM2plus

  4. You have the remove all holes setting enabled, disable that and it un-bricks...

  5. Thanks for completing the changes and building the package. If you like to maintain it, I think it is better to format numerical values like this: if str(GetType)=='float': GelValStr="{:.5f}".format(GetVal).rstrip("0").rstrip(".") else: GelValStr=str(GetVal) it is better mimicking the GUI. The original code will give rounded values with 2 decimal places even when the GUI shows more decimals. For myself I have changed the plugin to make an CSV file because my main purpose is to compare different profiles and I can feed that directly into Excel to show the differences.

  6. Not in the list; the company I work for is developping PVC filaments to be printed on the S5 for prototyping of pipe fittings products. So far there is no way to avoid degredaded carbon buildups in the print core so I'm designing a new nozzle to fix that. Also, not in the list. We started printing HDPE that way cheaper than PP but HPDE does not adhere to the glass build plate. Still figuring out a solution for that...

  7. Experience in Ultimaker R&D is that PVA stays fine for months when humidity stays in "normal office conditions". Let's say 20-25degC, up to 55% RH. This holds for Ultimaker PVA, other PVA's we have tested are much more sensitive to moisture! Here in the Netherlands in summer, sometimes humidity goes above 55%, and temperatures sometimes rise to 30degC or even hotter. The reliability of printing PVA then drops to unacceptable levels: too many prints fail. Cause for failures is that the filament gets too soft for the feeder. The statement that PVA gets brittle with moisture is opposite to our experience. Both temperature and moisture make PVA soft.
