newbie with issues

#1
So i just got my gmax 1.5xt+ and when i go to auto home it runs to the x and y endstops goes to center of build plate, does its bl touch thing, then will go to next point and smash the head into the bed then move the Z axis up about an inch every other point,then tries to print mid air. Itll sometimes make it to multiple points, then again try printing mid air but then jumping back down to the bed. I kinda feel mental cause i cant get it to auto home correctly to print.

sounds like your starting script may be wrong.... try this


G28 X0 Y0 ; Home X and Y axis
G28 ; Home all axis
G29 ; Auto bed leveling probe
M218 T1 X33.90 Y-0.3; Set 2nd extruder offset. This method is better than setting in in the extruder tab since it can be updated easily later
M201 X600 Y600; Set X and Y acceleration values
M204 S600; Set default acceleration
G1 Z15 F5000; Raise nozzle
M106 S[0]; Turn off fan
M104 S[extruder0_temperature] T0; Layer 1 temperature for extruder 0
M109 S[extruder0_temperature] T0; Layer 1 temperature for extruder 0
M104 S[extruder1_temperature] T1; Layer 1 temperature for extruder 1
M109 S[extruder1_temperature] T1; Layer 1 temperature for extruder 1
G1 X210 Y210 Z5 F9000


that should do it
