Several serious issues in MBot Grid II+


hi, wow, i been banging my head trying to fix this, i just got my mbot 3d grid II+ and was getting the left back extruders not lining up and would tilt the build plate, well this fixed it ON SIMPLIFY3D,…simplify3d can export x3g files ,!! prints come out perfect, thanks


Hello, I use Simplify, and I commented some lines from the original “starting script” and that worked for me with my MBot Grid II Single. Now the table does not hit the extruder in the left side, I share the modified script:

; **** GRID II start.gcode modified Sepradel****

How you change starting script?


Sorry for the delay in responding.
On the Scripts tab, just edit the Starting Script tab. I hope you still find it useful. Cordial greetings:
