Leave them out if you want to see Z motion or put some spinners on. * Slightly thinner rear Z idlers: now they fit within the extrusion thickness of 15mm. Two benefits: more space for a probe back there (hint, hint) and now the center tensioner fits a regular 12mm BHCS, so no cut screw or washers are needed anymore. -* CAD and STLs for alpha-3 are now available.

The original V0.1 bed assembly is gone, for a smaller file size, but Fusion is failing to export, so .step only for this one. * Want to contribute? PRs would be welcome for these improvements: * Integrated probing solution * Rear side skirts with less material. Duplicating the front skirts adds unnecesary material and gets in the way of a rear outlet. I got tired and chose to release this instead of modding the skirt. Other improvements matter more. @@ -98,7 +98,7 @@ This BOM preview is for Alpha-4, though there's no expectation that these parts | Fasteners | M3 heatset inserts | Yes | For motors, bed mounts (2 + 3), motor skirts (4x3), z belt attachment (4) and more | Z Drives | GT2 belt | 3x~450mm | | Z Drives | GT2 16t pulleys | 3 | -| Z Drives | MGN7H 150mm | 2 | Ideally upgrade to MGN9C on the X carriage and then get only one of these. +| Z Drives | MGN7H 150mm | 2 | Ideally upgrade to MGN9C on the X carriage and then get only one of these to repurpose for a front Z drive. | Z Drives | NEMA14 (for alpha3 or alpha4) or NEMA17 motors (for alpha4, when released) | 3 | Needs to have enough hold torque.
