after you guys left i got both X and Y axes working properly, in the correct direction, and the endstops too! now i was even able to home it! here's the repo: https://github.com/sudoroom/Marlin/tree/quickcircuit marlin can be uploaded with regular arduino, it's an arduino mega 2560 we still need to enter the correct values for stuff like DEFAULT_AXIS_STEPS_PER_UNIT DEFAULT_MAX_FEEDRATE DEFAULT_MAX_ACCELERATION although really only the first one is necessary. then we need to either find a solenoid or use this servo to do the Z axis, and configure marlin to control it appropriately from a Z command or whatever Z instruction gets produced by stuff like PCB2GCODE -jake
