Malyan M180 - complete Upgrade [Dual Bowden Extruder] [silent]

thingiverse

**Malyan M180 - Upgrade to Dual Bowden Extruder for Enhanced Performance** I decided to replace the heavy dual extruder head with a much lighter bowden extruder, allowing the M180 to print faster and quieter. Due to the limited slicers that work with the mighty board's .x3d format, I also upgraded the complete board and LCD screen. (This change also gave me silent stepper drivers.) *I removed the black plastic covers from the front and sides to get better access to the print bed, but this is optional.* *Updated parts to fit alternative drying bearings will be added soon.* **Required Components:** - 40cm of V-slot 2020 aluminum profile - 4x V-slot wheels - Aluminum Gantry Plate - new printer board and display - 5x TMC2208 stepper drivers - 2x V6 hotends - 2x bowden drives - 2x LM8LUU bearings (or alternative 4x "DryLin R - RJ4JP 01-08") - 2-3x optical endstops - PTFE tube - fans **Optional Components:** - 24V LED stripes - power module - profit **Where to Find the Required Components:** - TMC2208 stepper drivers (pack of 5) I have had great experiences with stepper drivers from FYSETC: http://www.aliexpress.com/store/product//3480083_32848553467.html - Heat sinks: http://www.aliexpress.com/item/1/32851156033.html - Printer board and display After my latest experiences, I recommend the FYSETC F6 board for people with Marlin experience: https://www.aliexpress.com/store/product//3480083_32969291649.html *(also available on FYSETC store as a full kit with stepper drivers, or even buy with classic Marlin LCD depending on personal preferences.)* or the Lerdge board for most easy setup: https://www.aliexpress.com/store/product//1948493_32962063464.html - Power module for automatic power off after printing or at short circuit: https://www.aliexpress.com/store/product//1948495_32809334869.html - Model cooling fan: *make sure to buy 24V version, one or two as you prefer* https://www.aliexpress.com/store/product//1948493_32813027533.html - Bowden drives: (2x) https://www.aliexpress.com/item/1/32663762254.html *choose with drive gear* (cheap and easy way) - Mounts for extruder motors: (2x) *mount at the back of the M180* https://www.aliexpress.com/item/1/32812747579.html - Hotends: (2x) *make sure to buy with 2m wires* https://www.aliexpress.com/store/product//1948493_32839644652.html (24V hotend) - Aluminum V-Slot Gantry Plate *full set with wheels, nuts, screws etc...* https://www.aliexpress.com/store/product/1/1752067_32968686608.html - Nuts, Screws etc. https://www.aliexpress.com/item/1/32926295712.html *M5 Drill Tap (hotend mount need to get thread drilled, and 2020 V-Slot alu profile may too)* https://www.aliexpress.com/item/1/32877137174.html *M5 screws (you need something like 20mm, 30mm and 40mm)* - 40cm Alu 2020 V-Slot profile: *somewhere on eBay* **Parameter Setup:** - recommended stepper driver: TMC2208 (jumpers on MS1 and MS2) @ 0.4 Vref on X and Y axis and 0.3 Vref on Z and E - Steps per mm: 94; 94; 1585; 94 (X;Y;Z;E) - Acceleration: 1200; 1200; 20; 800 (X,Y,Z;E) - Max speed (mm/s): 300; 250; 75; 100 (X,Y,Z;E) - Printing area (mm): 245; 150; 150 (X;Y;Z) - PID values heatbed: 181.6; 8.4; 981.1 (P; I; D) - PID values hotend: 1169.9; 61.3; 5581.9 (P; I; D)
