It took awhile to find I had the same problem. The traces are visible when the header removed. A real pain to try to cut the jumper. GREAT idea by o_lampe!! Connected a 12V SLA battery across the pins and blew the jumper away completely, no residual resistance. Since I had to do them all, I made a two pin connector with a foot of #22 cable. Plugged it in and then connected to the battery. Tby billyb2 - RAMPS Electronics

I set current limits to max. the stepper motors supplied by folgertech are 12 V so they cannot be overpowered by the 12V supplyby billyb2 - Prusa i3 and variants
Stepper motor settings: Lots of discussion about this, BUT: I was surprised to find the stepper motors supplied by FTech are 12 volt motors. Since the power supply is 12 volts as well, no current limiting should be needed. Thus the current pots should be able to be at maximum as the motors will not draw more than they are rated for. So they shouldn't overheat. I see most motors are rated foby billyb2 - Prusa i3 and variants

did you check the motor current settings? If too low, they won't move. too high and they get hot. clockwise turn of the pot will increase current Also when I first got mine going, I had to change the config file to reflect the x axis direction and limit switch. The correct settings are: #define INVERT_X_DIR true #define X_HOME_DIR 1by billyb2 - Prusa i3 and variants

I got my printer kit about a week after shipment confirmation. The material list was glued to the inside of the USPS box. The hardware envelope also had a contents list. there were no missing parts. Assembly took a couple of days and generally went pretty well. This is my first time playing with 3D printers. I had three problems: 1.
