No it is not, i do not have measurements, but i can get them tonight, but the nozzle is off the bed in both the "x" & "y" axis when at the home position. I have changed the bed dimensions in Slic3r to "fool" it to close to center, but i would like to not have to do that. I have tried everything i can think of to access the firmware, but since i am noob to all this stuff, i am unsure how to access Marlin. I have tried the Arduino software but i am unsure of the type of board this Chinese company uses.
