Thank you all! I ended up ordering couple of E3D thermistors and will check how they behave at 275 C. E3D Thermistorby uticatechclub - Developers
Quotedc42 The thermistors sold by E3D are rated to 300C. You are most likely correct. Now I feel bad because I gave away my Titan with original hot-end. I will buy one I guess. Thank you for pointing it out. I was hoping that someone could confirm the actual temp range of NTC 3950 100k sold in China and elsewhere in US.by uticatechclub - Developers
Hi, I am learning to print carbon infilled, nylon filament (https://markforged.com/product/onyx-filament/) on my custom designed multi-tool machine that is driven by Marlin bugfix-2.0.x firmware. This filament is printed at 275 C on original Onyx One printer. I have configured new all-metal hotend (actually separate direct drive extruder) with rather expansive E3D titanium heartbreak, heated bloby uticatechclub - Developers
It is under 3 minutes after bed insulationby uticatechclub - General
Sorry, I can't tell you the exact time, but I was able to significantly improve it by insulating the bed. Example: ASA printing requires 110C on the bed. Initially I had hard time reaching it, because Marlin would time out waiting on temperature advancement. Then I calibrated bed PID and increased Marling per/degree waiting threshold. I was able to reach the temperature, but it took forever. Bedby uticatechclub - General
If successful, this year will be my third one. An amazing event full of talented developers. Organizers are very friendly as well as people in the area. What makes it special, is the fact that it is away from big cities, making it possible for only determined participants. With students, we are planning to bring our next gen multi-tool 3D printer. Ten hour drive from upstate NY does not discouraby uticatechclub - General
Quoteo_lampe Quoteuticatechclub Could it be also true, that reducing existing drive gear by the same ratio achieved by reducing 1.75 mm filament to 0.8 mm filament would be good enough? Am I over simplifying? I don't understand what do you mean with reducing the gear? I mean making it smaller proportional to how much smaller in diameter the new filament became.by uticatechclub - General
Excellent research o_lampe! Regarding your conclusions on drive gears and teeth: May be we could make assumption (based on vast empirical work accomplished by RepRap community) that popular drive gears, their geometry and tooth configurations are quite usable with 1.75 mm filament. Could it be also true, that reducing existing drive gear by the same ratio achieved by reducing 1.75 mm fby uticatechclub - General
Thank you o_lampe. I just noticed the link in your post leading to your previous work - very interesting... I will take a good look at your findings.by uticatechclub - General
Thank you MKSA. You nailed it in your last sentence: "Now if you are OK for a lower flow, indeed you can scale down everything. 3D pen use a very small motor, yet a 1.75 mm filament." I am OK with the fact that print speed will go down to achieve higher resolution. And I am very much embracing the point of scaling down everything. What bothers me with 1.75 mm filament in such application isby uticatechclub - General
Greetings to All of you! Do any of you heard of a filament (PLA in particular) that is thinner than 1.75 mm? Is it possible to purchase it somewhere? I can't get away form the idea of developing very light weight direct drive extruder paired with 0.2 mm or even smaller nozzle. It would be nice to print small parts with higher resolution. I am aware that few tried forcing standard filaments thrby uticatechclub - General
