BabyBelt Pro (V2.6, see branches for V1, V2, or v2.5)
Whats new for v2.6
- Changed from 3 MGN7H rails (2X 1Y) to 1 MGN9C(Y) and 1 MGN12C(X)
- Removed 2mm screws (2.5s still needed for steppers and some hotend parts)
- Added M3x6 BHCS (Y Gantry to MGN12 rail) and M3x30 SHCS (new X gantry to frame)
- enhanced X gantry components for increased stability
- X gantry now uses heatsets M3x4x5 (Voron style)
- Backwards compatible with 2.5 BOM rails (mgn7H)
- Improved hole and screw insertion patterns for easier installation on Y axis
- Revised X/Y stepper mounting for easier install/maintenance
Remember when you didn't need 30 different types of screw to build your 3D printer? Printcepts remembers...
We strive for a minimalist approach and don't go adding hardware "just because". If there is a screw that isn't an M3x10 or M3x20 SHCS we've got a very good reason for it!
Printcepts started with a concept of taking parts you had lying around and making use of them. We want to thank everyone who gave us feedback, who wanted us to improve and we took that to heart! At it's core the Baby Belt Project will have its roots in re-using parts and being affordable. That's why we
