Hey guys,

I have recently made a 3d printer with a ramps 1.4 and marlin. Everything including homing works magnificintly. However, when I move the x and y axis 200mm away from home, The axis stops in the middle of the printer and seems to not move anymore. I thought it was a problem with the steps setting in the firmware, so I changed the firmware according to Triffid Hunter's guide. Even after that, it doesn;t seem to go more. I calculated the steps per mm are
x,y: 80
z: 2560
e: 94.31412

I'm using JK42HS34-1334AC stepper motors, and I do have jumpers underneath the motor drivers (If that matters).

How can I fix this?

Do you have the bed size set properly in configuration.h?

Do a M119 and check the endstop status, did the max endstops get triggered after the move? If they did, disable them in configuration.h. The define for that is right after the endstop pullup section.

There are different ways to get full travel. I just add neg offsets to get travel needed. I just add it to the firm ware. Example -30 to 200 for my y axis.
