Hi, take a look at the original I sell. It's bit more expensive, but nice parts and proper build documentation. I also have all profiles ready and it is precalibrated.by prusajr - Prusa i3 and variants
If you look at the driver datasheet, they are supposed to be cooled via thermal pad on the bottom. It is advised against to cool them with heatsink on top of the package, as it provides a lot of stress on the chip package and cause failed drivers. RAMBo mini has thermal vias and 4 layer pcb to cool it down the proper way with the whole PCB. The current for rambo mini is set in pins.h, it is notby prusajr - Stepper Motors, Servo Motors, DC Motors

Ahoj, tohle neni vanilla, to je sgraber i3ext. Jestli máš problém s moc plastem, zkus nejdřív použít příkaz "M221 SXXX" kde XXX jsou procenta kolik plastu má tiskárna dávat oproti původní kalibraci.

Zdravím přátelé, konečně jsem se dostal k tomu abych se taky podíval na české fórum. Docela to tady žije. A jsem moc rád, že taková spousta lidí staví moje designy! Koukal jsem, že tu někdo občas shání rámy pro i3. Já ja vyrábím a velkobchodně prodávám po světě, jenže to pak vychází dost draze. cca okolo 2200Kč. Nicméně rád bych udělal speciální nabídku pro členy fóra za 1700Kč včetně DPH. Proby prusajr - Prodám, koupím / komerční nabídky

Hi, guys feel free to make them. I am really working hard to get the pro drawing made. It is GPL v3. We made a load of tweeks over the phone with my machinist, so I have to reverse engineer it myself, lol.

akhlut If you insulate the heater it will be pretty darn effective, heat basically doesnt escape thru the stainless :-)by prusajr - General
Great to hear akhlut. I have here one LulzBot printer modified to run with my nozzle and I print there at 245°C :-/ But I had to mount a fan pointing at hobbed bolt, otherwise it gets unreliable. On i3 it is fine. It is really interesting new experience, for example I am able to extruder pla from 190°C upto 280°C :-)by prusajr - General

Check if your hobbed bolt isn't getting too hot?! Aduy is right BTW, the heat has to go thru SS which is insulator. 270 is tad high tho. How quickly you print akhlut?by prusajr - General
