  1. I have rtitan which should be similar to your filament. They also advice 240-260 C. I found that 232 is best temperature and 98-99% flow, fan 30-60%. 240 is also to high in my case. At 250-260 C i hear popping... This material can also be printed at 205 C (almost the same as 232 C). It is weard because datasheet says it is way below melting temp (235 +-10 C). Anyway, I think it is great material for mechanical parts, but not so good for overhangs and complex models Also, I use heated bed at 85 C and I print on clean glass without warping at all. Parts come out easely when bed cools down.
  2. I found Ultimaker tutorial for that. I'm curious how did I get perfect prints in first 30 h of printing... Conclusion: 1. cable was out of it's place (there is slot in side panel behind cable) 2. Pulleys were not tightened in right place (almost all of them) 3. G code was bad I solved everything and I'm happy to continue printing 😄 stu_le_brew thx for everything. good luck
  3. There is g-code in attachment if someone need. Sorry for long post UM2_Luca_postolje.gcode
  4. Thank you for answer. I think that Y endstop wires are in right place. As you can see on image from the first post; lower wire heat shrink was rubbing against left panel. I guess that there should be more space between left panel and belt. I know how to remove endstop and probably I could make more space by untwisting the wires. The machine was running for 34 h only and I wanted to check here before I touch anything. I don't understand why would this rubbing cause triggering, but this topic got me thinking: I think the rods are clean and well lubricated. I can see some oil on hot end bearing seals. There is almost same resistance when moving hot end in X or Y direction by hand. BUT all rods can move left to right / back to front (axial direction only)! All of them can move around 1 mm, but this one (Back X linear shaft, the one with Y motor attached on it) can move more than 2 mm Is this normal? Do I need longer spacers behind pulleys? Moving pulleys towards side panels doesn't feel right. If i move this shaft to the far right the belt is not touching wires anymore, but there is only 1-2 mm clearance. I took closer look on failed print, and I can see that issues started to happen before layer shifting. I guess it's more likely that warping happened and nozzle hit the part and printer skipped steps every few layers. Not sure about this, but I don't like idea of starting machine right now to do more testing. What to do now? Should I investigate by myself or take machine to seller? I was hoping someone from Ultimaker team will suggest me 😄
  5. Hi everyone. 2 weeks ago I bought UM2+ and love it. All prints came out perfectly with no issues untill last night. I was trying to print 8 h long run and layers were shifted after 1/2 print time. After reading this forum I found that someone was asking is motor belt rubbing on endstop cables. I think I have this is a problem on my machine. I can see that one of the small belts is rubbing on endstop. Not sure this coused skipping steps, but it doesn't look healthy. After 1/2 of print time the skipps started to happen and it continue almost untill the end of the print. The skips are all in the same direction. What should I do? I also attached the picture of last print which came outh perfectly. This one is made with almost the same cura settings.
