So i got my 2 broken stepper drivers back, and after some tuning they are now working, and i now have a machine that moves X,Y and Z and heats the extruder and reads the temp correct. The extruder stepper still isn't turning, but makes a high pitched noise. The X and Y axis however move to the other side of where i placed my endstops, and because i don't want to move my endstops i want to turn bby possenier - General
i don't think i fall in the category of people above me i'm a theater technician, skatepark designer and freestyle bmx'er (www.crankbmx.com) i did get a C64 at age 6 and at age 12 build my first print to control a lego car with my commodore i think that explains more what i'm doing building a reprap and why my BMX team members call me a nerd.by possenier - General
Found it! well, it ended up being what i toughed it was, those capacitors are wrong. i mailed the guy who i bought it from, and he said another customer had the same problem, so my boards are back to Poland for replacement so make sure they say 100-50v and not something else. pieterby possenier - General
i swapped the others in the Y-port and they don't do the motor turn, but the Y-stepper in any other port does work. this is how i now know the problem is with those stepper drivers. my main problem is that the stepper work "a little bit" since they try to make the motors move. this is what trouble's me, it would be easier if they didn't work at all. anyone know if it could be those capacitors?by possenier - General

so i did some more testing and changing everything, and i think the problem is going to be located in my stepper drivers. when i test them without motors, they all work perfect (as in the motor leds light up the same way when i send a move command, no mather where i place the driver) the thing changes when i add a motor, then only the Y-board lets the motor turn, the other 2 let the motor buzzby possenier - General
i switched the cables as well. and tried changing the resistor value the gen3 boards came with firmware loaded: as for software, i didn't change a thing apart from letting the software now it needs com port 3by possenier - General
hello world, greetings from belgium i started building a prusa a few months ago, and now it's ready for as far as i can make it ready, but off course as with all great electronics, it doesn't work directly. i'll start with saying what i have: prusa mendel with plastic from nophead and gen 3 electronics from someone from poland (ebay.pl) all other parts come from the hardware shop or mendel-parby possenier - General
