FABtotum Feeder & Steeper Flange

thingiverse

This is a mounting flange designed specifically for attaching a BMG Extruder to a FABtotum printer. Its purpose is to be installed in the back panel of the FABtotum, necessitating an adjustment in the corresponding hole pattern on the panel. Since I haven't carried out this modification previously, I created a makeshift mount using duct tape as a provisional solution. Proof of concept can be viewed at https://photos.app.goo.gl/2DEnYhxaRjsCA9QXA. The necessary parts include: 1x M3x10 DIN912 screw 3x M3x30 DIN912 screws Important note: One of the connectors, either the extruder or printer, must be inverted to ensure proper functionality. Failure to do so will result in incorrect stepper motor direction, requiring a cable reconfiguration as illustrated below. S---P | S---P (Stepper --- Printer connector) 1---1 => 4---1 2---2 => 3---2 3---3 => 2---3 4---4 => 1---4 Don't forget to recalibrate the extruder's steps after installation.
