BI V2.5 V-Slot Magnetic Ball Joint Conversion

2019-03-09 Added improved STL's for Belt connector and connector insert.

• Belt connector lower profile, better nut lock for easier assembly
• Connector insert less prone to breakage

It is primarily a V-Slot conversion and conversion to magnetic ball joints, that also uses belt drive (I converted to the Boots Belt kit before starting this conversion.

At this stage it is trying to maintain the default effector so as to reduce the amount of parts replaced, complexity, and the cost of the conversion.

Special thanks to clefranc for working with me on design of carriage plate and effector clips.

Special thanks to Lykle who collaborated with me and did the modelling of several alternative effectors.

Printed Parts

There are several choices/options to be made here.

*Effector Options*

Custom effector reusing boots plates

This design developed in collaboration with Lykle increases build height by raising the hot ends http://www.thingiverse.com/thing:916251

E3D Chimera / Cyclops

See the awesome low profile custom effector designed in collaboration with Lykle at http://www.thingiverse.com/thing:916142

Or alternatively if you want to keep using the boots effector use http://www.thingiverse.com/thing:916206 also designed by Lykle

*Belts*

I printed these in ABS, Ithink with 20% infill and 2 outer perimeter shells, supports are needed for the endstop flag and inner section of the Belt Connector, the insert I printed at 100% infill:

• 3 x Carriage_Plate-Belt_Connector_V1.stl
• 3 x Carriage_Plate-Belt_Connector_Insert_V1.stl

If you don't have boot's belt kit, print the following at 40% infill with PLA or ABS, a 0.4 mm nozzle is recommended with 0.2 mm layer height (ABS recommended):

• 3 x 754491-Idler Pulley-Final Prod.STL
• 6 x 754491-x2 M5 to M8 v2.STL
