home build smart rap corexy almost done .. was going to print a test cube but didn't work at all so need to iron out some issues. Marlin on ramps1.4 board repetier host I tried to calibrate the extruder stepper motor but the extruder motor is making a lot of noise.. it looks like it is trying to feed WAY faster than the nozzle can handle the plastic. It feeds and reaches a point that it is begiby dmac257 - Smart_Rap
I am building my first 3D printer - SmartRapCore XY - highly modified (started bigger than plans) motion seems to be pretty accurate - when told to move 10CM in any direction it looks pretty close but haven't calibrated the steps yet I have a photo-sensor on X and Y directions that will halt motion and Zero each direction when I click HOME in either direction. I want to do auto leveling of theby dmac257 - Smart_Rap
I have in hand a 12V power supply .. arduino mega 2560/ramps 1.4/ 5X A4988 2A stepper driver boards .. 4 NEMA17 steppers motors for my first build. I was supprised to see that the rated voltage for the stepper motors was only 3.1v 1.7a and I would like to know if this is correct or did I get the wrong steppers. I don't want to hook up the electronics before I double check. Thanks in advance, dby dmac257 - Reprappers
