Today the first prototype of a planetary herringbone gear for nema 17 stepper motors has become ready. It is fully printable . With this little adapter you can raise the power of your nema 17 steppers a lot – it has now 5 x more torque. Herringbone planetary gears for nema 17 steppers weiterlesen
Today two more upgrades for my good Prusa I3 B. No 1: Infrared filament monitor. Detect filament blocking with routines to stop/pause 3D printer and let the user interact to solve the problem. This is an alpha development thing connected to an Arduino mini pro. It detects the movements of the little wheel and can count the movements (meters) the filament made. No 2: Bracket … Pimp my prusa – part2 weiterlesen
After I got some magic smoke from my good old GT2650 board from the modded Prusa I3 B pro (which is a dual extruding I3C pro version now) there had to be made some decisions: Replace the old board with a new one or take a more recent faster version? Replace the old MK8 direct drive extrudes with some more reliable ones? Two stepper motors … Pimp my prusa weiterlesen
After I saw that user „James VanDusen“ posted about „8mm m8 threaded rod“ in the MPCNC forum https://www.vicious1.com/forum/ I decided to do all these steps to try it out. So this morning I dissassembled everything around the rod, printed out the new part F-XYZ_T8.stl from https://www.vicious1.com. In my case (25 mm IE version) you can find it here: https://www.thingiverse.com/thing:790533/#files What I didn’t find is a part … More MPCNC upgrade – new z-rod weiterlesen
Hi, yesterday I began to update my MPCNC. It now has a E3d printhead with a simple bowden extruder. Additionaly for the x- and y-axis the A4988 drivers are replaced by a TMC2100 Silent stepstick each. And to make things nearly perfect I made an update to Marlin 1.2, which came out two days ago. Thanks a lot! So the machine is so quite that … MPCNC upgrade weiterlesen
