BigTreeTech BTT002/TMC2209 Config for Průša MK3S

Requirements

• Průša MK3S or MK3 with MK3S upgrade (required for filament runout to work properly)
• BigTreeTech BTT002 motherboard
• 4 x BigTreeTech TMC2209s (DIAG pin location differs from Watterott's & similar designs)

Upgrade Notes

• ⚠️ Cut or desolder the Z & E driver DIAG pins or they will interfere with PINDA & filament runout detection. ⚠️
• Set the jumpers under your drivers to "TMC2208-UART MODE":

Changes to Start G-code

The W in Průša's G28 W ; home all without mesh bed level G-code does not exist in Marlin and G80 ; mesh bed leveling cancels the current motion mode, so no bed leveling will take place.

PrusaSlicer

Paste the start G-code block below in the Printer Settings tab's Custom G-code section. Use the Filament Settings tab's Custom G-code section to add the Linear Advance (M900 K0.0) value since it can be saved on a per-filament basis.

G90 ; use absolute coordinates
M83 ; extruder relative mode
M104 S170 ; preheat extruder to 170
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
G28 ; home all
G29 ; mesh bed leveling
G1 X0 Z0.6 Y-3.0 F1000.0 ; go outside print area
M109 S[first_layer_temperature] ; wait for extruder temp
G92 E0.0
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line

Cura

Paste the start G-code block below in the Start G-code section. Don't forget to add your Linear Advance (M900 K0.0) value in the start G-code block below:

M900 K0.0 ; place your linear advance value here
M104 S170 ; preheat extruder to 170
M140 S{material_bed_temperature_layer_0} ; set bed temp
M190 S{material_bed_temperature_layer_0} ; wait for bed temp
G28 ; home all
