I have an old Gmax 1.5 that was bought abt 5 years ago and the electronics boards gave out. I m in the process of upgrading to Ramps 1.4 .
Ive replaced the dual extruder with a single extruder and am using the ramps smart controller my problem is if i try to home all axis the z
axis just has a loud scream but wont move y axis wont move as well as the x axis. I installed marlin ver 1.1.9 and i dont know why im haveing so much
trouble with just a simple hookup with ramps, also can i use the old G max lcd controller with ramps
