SCOUTcorexy XY_Stage XCarriage !!10mm!! YCarriage 10mm HorizontalRods SingleHotend

NOTE: this is continuously being re-uploaded as i modify the design (which is very much in WIP) so make sure you come here often.

Update 17/06/2016: re-did the bearings block and the hotend mount now has detachable belt grippers for off-site clamping then insertion onto the carriage, the grippers are now printed separately ensuring correct orientation during printing. Some other modifications at the hotend-clamping bolts.

This is the 10mm XRods variation of the previous 8mm Rods XCarriage. It is designed for Bowden setups and Horizontal Rods, getting rid of most of the static and dynamic errors that affect printing during the accelerations/jerks/etc of a 3D printer (discussion here: http://forums.reprap.org/read.php?1,668254).

Sketchfab 3D model with exploded view here: https://skfb.ly/OVzz

DETAILS:

• X uses 10mm rods and LM10UU bearings
• Y uses 10mm rods and LM10UU bearings
• belt is gt2
• Hotend is a clone of E3Dv6
• axial fans are 30mm
• radial blowers are 4020 type
• all in all the XCarriage is very symmetrical and any forces applied during accelerations, jerks, etc, are evenly distributed so that the nozzle remains as fixed as possible.

Features:

• 72.75mm XCarriage (the Belt-Catchers go inside the YCarriages so they are not wasted space);
• Belts go in straight line and in the same plane from YCarriages towards the XCarriage;
• Belts can be tensioned with simple screws and dome-nuts pressing on the belt, forcing it into the niche designed for it; belts can be independently tensioned;
• Hotend supported both upside carriage and lower side by the 4 screws;
• Dual-30mm fans for coldend cooling;
• Dual-30mmfan (or squirrelcage blowers) for part cooling [still very undecided here];

TBD:

1. some way to remove wiggle/play from the linear bearings
2. design it for dual hotend
