Marlin 2.0.5.3 Settings for BIGTREE SKR 1.4_Turbo, TMC5160 to drive Ultimaker UM2+ 3D Printer version V2 contains updated and sanitized header files to reflect changes in configuration.h configuration_adv.h pins_BT_SKR_c ommon.h search for "habe" to find all modifications
reduced spill when preloading hotend before print. increased motor currents to 800 mA and 32 microsteps to improve wall smoothness.
1.Required Hardware a. 1 BTT SKR 1.4 Turbo b. 4 TMC5160 Stepper drivers c. 1 BTT DCDC Power Module for SKR 1.4 d. 1 PT100 Pre-Amplifier (Ultimaker Style), 3 channel, must use VDD = 3.3 VDC (DIY), see KICAD file SKR14_PT100_Amp e. 1 MOSFET Adapter Board to run Hotend Fan off of SERVO connector (DIY), see KICAD file SKR14_FAN_DRIVE
- What will these Mods do? a. Enable flicker-free dimmable Case Lighting, using the original Ultimaker Case LEDs @ 24 VDC and high frequency PWM dimming b. enable PWM-controlled Parts Fan c. enable PWM-controlled 5VDC for use with Hotend Fan (needs extra MOSFET and Diode, driven from SERVO connector) d. increase Bed-Heater and Hotend-Heater PWM to 60 Hz to smoothen power consumption (note: you must use PID for Bed Heater). This improves print quality! e. enable ulticontroller display and Clickwheel+LEDs as published by Anthrix https://community.ultimaker.com/topic/30786-ultimaker-with-skr-14/
