JPT's Low Profile Y-Carriage for Igus KSTM-08 Bearings on MendelMax 1.5 by JPT

Last crawled date: 3 years ago

This carriage is designed to replace the printed carriage and the acrylic glass plate at once. Which allows to lower the heatbed by 30 to 50 mm, gaining height for printing objects.
WARNING: Not for printing but for cutting/milling (eg. acrylic glass)WARNING: Not tested yet
Other benefits
less tolerance in heatbed positioning
easier moving of the carriage than with 4x LM8UU (hopefuly)
Some dimensions:
Distance between Y-rods: 100 or 150 mm
Belt mount: M3, any size: 10 to 12.5 mm or 17.5 mm
Heatbed Mk2 mounted with 3x M3 screws, distance 209 mm
Holes are either 4.5 (KSTM) or 3 mm (others)
Total size: 229x229 mm (theoretically ;)
If you mount the the rods with 150 mm distance, you will:
be able to mount the motor inside the frame (not my invention). I added additional holes for the belt mount, so you can move the motor 11.5 mm from the center if it collides with the Y-rod mount.
gain fewer tolerance from warping of the Y-carriage
TO-DO
does it collide with anything?
how to mount the Y-end-stop?
will the motor collide with the plate if mounted inside the frame?
define screw length
draw Y-rod mounts for 150 mm distance
add a mount for a cable chain
Updates
Added holes for different size belt clamps: 10 to 12.5, 17.5 mm (did not update renderings)
Added nut holder for KSTM bearings
