BigTreeTech BTT002/TMC2209 Config for Průša MK3S

Requirements

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

Configuration Options

Flags specific to this printer/configuration:

• MK3_FAN_PINS - Disable this for FAN_PIN PB9 and FAN1_PIN PB8
• GEARBOX_BEAR - Is printer equipped with a 3.5:1 gearbox on the extruder?
• TALLBEAR - Tall Bear (320mm)?
• SUPERPINDA - SuperPinda present?

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 default G-code does not exist in Marlin and G80 ; mesh bed leveling cancels the current motion mode, so no bed leveling will take place.

Below are some example start G-code scripts from popular slicers to get you started.

PrusaSlicer

• Set your G-code flavor to "Marlin 2" under "Printer Settings" -> "General" -> "Firmware" -> "G-code flavor".
• Use the "Custom G-code" section under "Filament Settings" to add the Linear Advance (M900 K0.0) value since it can be saved on a per-filament basis.

• Paste the start G-code block below in the "Custom G-code" section under "Printer Settings".
