TronXY X5S-400 Marlin 2.0 MKS SBASE Setup

thingiverse

So I got this TronXY working pretty well aside from the underpowered extruder, I figured I'd share my setup. The spoolHolder.stl is a spool holder I designed to move the spool back from the edge so it lines up with the extruder. Here's how I set it up: The X, Y, and Z axes are 400mm long. If you have the smaller bed, you can adjust Configuration.h lines 894 and 895 to match your bed size. I installed a BL Touch on the Zmin and connected it to pin 6 of J8 (P4_28). My Digipot settings are X:1.0, Y:1.0, Z:0.7, E01:1.2, E1:0.7. The two Z motors require these specific settings. I kept the original display but modified it to fit the SBASE requirements by cutting notches in the sockets so the cables can be plugged in backwards. To improve accuracy and stability, I replaced the 8mm/rev lead screws with 1mm/rev ones. If you haven't done this yet, I highly recommend it – the bed won't fall on its own, and the screws are more precise. To make this change, update Configuration.h line 623 from #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 1600, 90 } to #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 200, 90 }.
