BIQU B1 Y Axis Belt Cover for Auto Part Ejection

thingiverse

This cover is great if you want to automate your BIQU B1 to run 24/7! You will also need to: -Use my part ejector which bolts to the print head: https://www.thingiverse.com/thing:4999862 -Use a bed clearing script at the end of your G-code (or for OctoPrint users, use the 'continuous print' plugin). Mine is listed at the end of this text. -Change your start G code to prime off the edge of the bed to prevent build up of filament. Mine is listed at the end of this text. This particular model covers the Y axis belt, so that parts do not get jammed in there when they are automatically ejected. The two halves are connected using two 6mm x 30mm wooden dowels. Once assembled a flat platform is created which allows the parts to slide off easily. As it sits very close to the heated bed, I would recommend using PETG to prevent warping.
