Duet 2 Wifi Files for BLV MGN Cube reprap 3d printer, with Duetx5 extension.
../Designed-Upgrades are all the custom made parts for the 3Z axis project + 1204 ballscreew
../Thingiverse-addons are the optional parts downloaded from thingiverse to complete the project.
This project attempt to version the DUET 2 wifi config files for this project, attempted to be shared, documented & backuped.
-
Z Axis: Designed for 3 axis, using the DuetX5. At this time, installed only 2 Axis on differents motors/drivers (Z, & E1)
-
BallScrews: There are installed 1204 standard ballscrews. That would be 12mm rod, with 4mm pitch. The step per mm is 800. The math behind would be 200 * 16 / 4 = 800 (200 steps, 16 microstepping, 4 pitch).
-
Extruder: The extruder is a BMG Bondtech clone, in Direct Drive with E3Dv6 with all metal hotend. Initially it was set as E405.18 steps. The heater is 24v 40W. On the BMG web, is recommended 415, but 413-415 values are recommended.
-
Autolevel: The autolevel, initially was using IR sensor, on duet probe, but now is configured for a Cloned BLtouch to work on any printing surface. Since the DUETX5 is installed, the PWM servo of the BLTouch was configured there. Using the default piece of the project to hold the sensor, with X28.5 Y-5 offsets. Using 2 M3 nuts (2.39mm each), without washers as spacers, the Z offset is ˜2.3mm
Drives Direction
M569 P0 S1 ; physical drive 0 goes forwards (X1)
M569 P1 S1 ; physical drive 1 goes forwards (Y1)
M569 P2 S0 ; physical drive 2 goes backwards (Z1-Z2)
M569 P3 S0 ; physical drive 3 goes backwards (E0)
