@CarloK You are indeed correct! My SD card chipped 2 days ago when my printer stopped working but waved it off without much thought because it still reads on my ANKER SD card reader to my laptop… I did order a new 128 gig sd card but from what I heard from FBRC8, they said the printer will only read 32 gig cards at max.. Any last advice for a strongly recommended card before I cancel my Amazon order again? Haha 😅

@stu_le_brew thank you for the kind words and advice I have just reformatted the SD card on my computer yet it still doesn't work. Prior to not working at all, I had an issue where my card wouldn't read unless i held the card in with some pressure and duct taped so it wouldn't come out... Safe to say its the ulticontroller that needs fixing? SD card is operational when hooked into my ANKER SD card reader for my laptop but just not my printer 😕

Hey everyone, The universe has a sense of humor because leading to my business launch, my UM2E+ decides to stop reading my SD card with all my G-codes. There is a new SD card on the one so I will try that but I've read somewhere I would have to replace the ulticontroller overall in general if that doesn't work...Given my warranty expired a long time ago and ulticontroller is around $90, I was thinking of replacing it myself. Before I do that though, I was wondering if anyone else had a similar problem and if they fixed it. Please help! My pre-launch is in a month and my launch is by end of the year! Any feedback would be appreciated! Thank you!

How’s it going everyone? Running TPU 82A prints on my UM2E and I believe I dialed in my settings quite nicely. However… My print exhibits vastly weaker rigidity (infill) in the first 1/3 of the print. Non-surprisingly, it is also the only layers that prints supports. Anything after the layers that exhibit supports, the infill is fine. I’ve improved my prints by enabling retraction at a distance of 6 mm and a speed of 25 mm/s. The print comes out shiny and clean but I am beginning to think the retraction during the supports is possibly affecting the extrusion flow when it moves to print the part after the support have finished. I was wondering if anyone else had this problem and knows of a possible solution. Saved the settings I have for now and wanted to ask the community for guidance before l accidentally mess things up and waste time.

Filament was dried at 122F (Slightly less than the 125F mark on the dehydrator; for over 24 hours) Not too sure if it's moisture as the color changing desiccants I poured into the dry box is blue and not pink (indicating saturation of moisture). Seems to be the combination of speed, temperature and retraction which is an absolute headache. Additionally, I am hearing both sides of the story when it comes to z-hop, so that's another variable that is put into the equation of possibilities 😞

@gr5 Ahhh I apologize. I thought you were referring to the Fusion 360 design I converted. Attached below is the current settings I have and saved from Cura. Hopefully this is what you were referring to. Please let me know! RX-V1 Bottom for Ulti Com.3mf

Hey guys @gr5 @MariMakes Attached below is my 3MF file I have created from design in fusion 360. The print is oriented within cura so it stands and prints upright. Additionally, I've attached pictures of prints with the cleaner one from Cura 4.8 and the messy stringy mess from 5.0. Cant seem to tame the stringing or get back the same quality as the 4.8. Any advice on how to take on this issue? Filaments are dry and printing straight out the dry box. The messy print in the pictures were printed with these parameters: NOTE --> I changed the gcode flavor to Marlin... Nozzle: 235F , 0.4 mm size --> 0.2 layer height Bed Plate: 60F Infill: 2-%; Infill Line Distance: 1.75 mm; Infill Pattern: Grid Speed: 35 mm/s; No Jerk Control or Acceleration Control Retraction: 5.5 mm; 45 mm/s --> NO Z HOP ENABLED Cooling: Fan on 100% Support: Normal, Touching Build plate, Support Overhang Angle: 50, Support Pattern: Zig Zag, Support Density: 2-% Used Towers: Yes --> Tower Diameter = 3 Bottom 3MF File.3mf

@gr5 Thanks for the reply. I dehydrated the TPE filament within a food dehydrator and made an air tight dry box to print directly out of with a bowden tube. I seem to have got the retraction setting down to 5-5.5 mm and 45 mm/s. However, I now realized my print, (a simple tower with small 90 degree angle overhangs) is flimsy from the bottom but structured yet flexible on the upper. I have the infill density set to 20% with a grid pattern and the only layers on the bottom of the print affect are the same layer height as those with supports... Any advice on how to fix this issue?

How's it going everyone? I had a print profile for TPE (shore hardness 82A) and it printed flawlessly through Cura 4.8. Upon the update to 5.0, my prints started to string a lot more and come out with blobs with with the print fusing with the supports as well. Definitely the retraction setting if I'm not mistaken. Been tweaking it for a bit with no results... Think anyone can help me out? I have the original file for the part if anyone wants to check it out. Any help and advice would help thank you
