That's exactly what I've been looking for! Thanks. I noticed with the rev b it says that you haven't had a chance to build the new board yet, is that still the case?by Crusader68 - General
Im still very wet behind the ears when it comes to hardware and software interface, so I would love some help with this question. I love the Negative Graphic Display with RGB back light from adafruit, , and I was wondering if this display could be, not with massive changes, used with Marlin and the same basic circuit as the GLCD Smart Controllers that are available everywhere? I realize that theby Crusader68 - General
Dc42: I haven't finalized my choice of extruder, but I'm pretty sure it's going to be a direct drive. The parts kit I bought comes with a generic version of the mk8 type extruder, but I'm thinking about using an M2 extruder or something similar. I think that having as much support as possible guiding the filament into the hot end would be best with the high torque of the planetary gearbox. Denby Crusader68 - Mechanics
Can anyone help explain how the ratios(5:1, 17:1, 19:1 etc.) correlate to performance of a Bowden extruder? Do the higher ratios trade speed/step angle for higher torque? What ratio is the better option for a Bowden extruder?by Crusader68 - Mechanics
I tried it without the stepper drivers or any other inputs and it was working, but an error message keeps popping up on my Mac that says the USB ports are drawing to much power and it shuts them off. The strange thing is the arduino board doesn't cause this error message by itself but when I plug the ramps board in it triggers it, but I have the ramps and arduino connect to the 12v and 5v power sby Crusader68 - RAMPS Electronics
After uploading marlin firmware to my mega board, I plugged my ramps 1.4 in and added power to the ramps and the unit doesn't seem able to communicate with my Mac. After uploading marlin, I did test the just the mega with pronterface and everything was connecting and communicating well, but after attaching ramps there's no more connection. I checked my power supply(atx stolen from an old pc I hadby Crusader68 - RAMPS Electronics
