Hi there…now running into a weird issue with my ramps/steppers combination.
summary: I am testing all drives/stepper work correctly before final mounting them
Z works perfectly from lcd and pronterface or repetier.
Y doesn´t work at all
. power is ok and driving the four terminals on the ramps board
. mega is correctly attache as far as I know.
.I am running latest firmware for T8 leadscrew with no hot end.
.no, I am not using any enstops
. changed driver boards, and even the ramps one. No matter with combination of stepper/driver I use, I always got the same behavior… Z works, Y doesn´t at all, X locks and doesn´t move.
. amps are set at 0.7 on each driver, tried with more (up to 0.8) and less up to 0.45… behavior still the same
. I am using 17hs19-2004s1 steppers… accordinhg to the wiring specs… A is black A\ is green, B is Red and B\ is blue. Conneced directly to the ramps terminals I got this behavior.
.Firmware I am using is MPCN813_GLCD_T8, installed it several times just in case…
. all three jumpers are installed for the three axis on the ramps board.
. I sucked my brain fried checking this forum and the web to no avail.
Does anyone any useful hint or troubleshooting guide on how to tackle this… many many thanks in advance! happy to provide more information if needed…
