COMMENTS WELCOME
After designing V1 (https://www.thingiverse.com/thing:2553656/), I got some feed back over at Reddit (https://www.reddit.com/r/3Dprinting/comments/72tvfv/ellis_bot_corexy_request_for_comments/). So with that feed back, this is what I have come up with.
Design Goals:
Minimum maxium speed of 100 mm/s (150 mm/s would be great, 300 would be awesome) with decent precission and accuracy.
300x300x500 build volume.
100 Micron resolution.
Changes since V1:
Replaced most of the printed parts with metal tubing, 2 1/2" x 2 1/2" x 0.125", 2" x 4" x 0.125" and 2" x 2" x 0.125 (gantry part), and metal plates. Now it's more metal than your grandmas Norwegian black metal band.
Replaced pulleys with F608zz's.
Single Z axis motor, 3 acme screw design with 2 linear rail guides.
Should fit on a 24" deep desk (Pretty standard depth)
Shrunk X and Y down to 300 mm (Well it's a tiny more, but 12" build surfaces will adhere). 500 mm on the Z still.
Drill though the frame, instead of using a lot of corner brackets (though can add them on if needed).
Went up to M5 for a lot of the screws.
Turned motors inwards, which will allow for an enclosure to be built easier.
Features:
300 mm x 300 mm x 500 mm build volume.
3030 extruded aluminum frame. None of that wussy 2020 stuff.
"Easy" Belt tensioning.
Designed around a real E3D V6 hotend and J12A3-4-Z/BX sensor, but designed to allow for easy swapping of parts.
Did a mention, less printed parts, more metal? This should be, in theory, more rigid.
