Hi Snapmakers, I have a new brand of PLA, which behaves unwieldy. So I decided to run a temperature tower to understand at which temperature to print with best. Turns out: None! Fired up my other printer, started a temp tower with the same PLA spool - what a difference! The printer knocked the tow…

It’s known that the thermistor is not properly secured and conductive ( frex, https://forum.snapmaker.com/t/whats-wrong-with-this-picture-printre-hot-ends/7757/7 )—it seems that the Snapmaker people just didn’t realize it was useful to smear in some thermal paste.

Yeah, but I was of the false impression that only the replacement hotends had this flaw… Stupid me.

OK, what a difference! Topmost print (most backward): SM2 at 210°C (not 100% sure but 200+). Second/mid: SM2 at 190°. Front/lowest: Fabtotum at 195°C. SM2 at 0.08mm layer, 80 mm/s, Fabtotum at 0.1mm layer 80 mm/s. Looking at https://www.simplify3d.com/support/print-quality-troubleshooting/ it is cle…

Definitely thermal paste is a must for good printing with the SM2. Sorry I didn’t see your post sooner or I would have chimed in, there have been several posts pointing to poor hot end temp control.

Hi folks, I now applied thermal paste to the thermistor, and obviously I was completely wrong: There is no change, the temp tower printed with the paste applied is exactly as bad as the one before. I decided to change the hotend completely for a test, since I suspected the thermistor to be defectiv…

I found bridging to be particularly challenging for these devices, and I have a 7" desk fan next to the printer I turn on after the first layer finishes. Besides preventing the bed from ever getting over 62C and possibly reducing layer adhesion I haven’t seen any negative effects. I have also fough…

The funny thing: My very first serious prints with SM2 were with considerable bridging, and I was/am rather pleased. However, that was with a different PLA brand. And it’s this green PLA that gives me headaches, other PLA workes much better, but not perfect, Thanks for pointing me at the summary ar…

So the original fan is a 2510 axial tiny tiny thing. Here’s all the fans: FYI: Snapmaker 2 & Enclosure Fan Information plus alternatives So I bought a 5015 radial blower with the same connector on the end (on amazon) and plan on disconnecting the built in one, connecting this one, and designing and…

Currently running the SM2 print at half speed, and looks better already. However, I may still have an extrusion issue! I can watch how the printer lays down the first bridge, and it is perfectly straight and nice, and while it adds layers above, the bridge gets pressed down - which may indicate over…

Struggeling with PLA - Nozzle temperature off?

Seems @Atom was faster and had success (only now stumbled across his post): Improving Print Quality Seems to be a point in favour of my theory…
