I just finished building my ft-5, I followed to steps and checked all wiring. Using Marlin V3 with Arduino 1.6.5.
I have got to the movement test, all endstops work all say _min: open and triggered, i check the direction of the x axis - moves it to the left and + to the right towards endstop, z axis + moves in down and - up, y axis will not move, i unplugged the right side stepper and loosen the belt on the left and tried again it just vibrates but does not move, i changed the driver to the spare one and its still the same.
When i press the home button y just clicks and stops, z moves to the endstop and just keeps trying to go further.
I read the forum about USB power frying components, when have the USB cable the LCD screen flickers.
I hope it has not damaged anything and i can sort my printer out.
Any help would be appreciated. Thanks
