I am building a new printer, my own design, Cartesian style. I have the X, Y, and Z axis completed and wanted to test. I am using the Azteeg X3 V2.0 controller board. I successfully downloaded the latest version of Marlin and am using Repetier Host on windows XP. I don't have the extruder or bed heater yet. I am able to use the manual controls in Repetier to home all of the axis with no problem but manual move commands are ignored. I tried issuing G0 F1800 X80 Y80 and those are also ignored. I can see the RX, TX lights flash on the controller board when I send move commands but no movement. Do I need to disable something in the firmware since I don't have heaters? What else can I try?
