Got tired of seeing my name in red in the recent changes....
I'm a graphic designer who purchased a (used) ShapeOko w/ the intention of automating some woodworking projects and extending my capabilities, esp. hoping to build my own custom brass hardware (and tools) so as to not be limited to what's available for purchase commercially.
I'm an admin on the wiki here, so glad to help out w/ any edits or other issues.
¼″ Drive Shaft Upgrade
- 1/4" pulley
- 1/4" aluminum rod
- 1/4" flanged bearing
- HDPE bearing plate (the central hole on the plate has since been enlarged using a tapered reamer to 13/16" and the bearing now fits directly)
- 5mm--1/4" coupler
- 4 7/32" 1.5" roll pins (used as motor stand-offs)
- 4 M3 screws 50mm long
- an assortment of washers
Since implemented double MakerSlide X-Axis, Acme Screw Z-axis and 1m Y upgrades.
- drill new holes to rotate X and Y motors 45 degrees --- DONE!
- drill new holes in X gantry plate to invert belt --- DONE!
- use 10 1" spacers for carriage--gantry plate --- DONE! but they wouldn't fit over the nifty new bolts, so had to use pan head screws and only used 6 spacers and an assortment of washers
- enlarge motor shaft hole in Y motor plate to accommodate moving pulley to outside --- DONE! Will test and see if it needs a thrust bearing or something.
- use 1/4" music wire and 1 1/4" steel bar for Y-axis belt anchors --- DONE --- tried single track shelf wall standard instead of music wire --- didn't like it, but spare length of 1/4" aluminum rod worked,
- use short lengths of single track shelf wall standards for X-axis belt anchors --- DONE --- but a hole needs to be enlarged --- DONE
- run wiring --- DONE!
- make a nice enclosure of Lego bricks --- DONE (but see below)
- dust collection --- pick up Dremel EZ Twist Nose Cap and use it to hold a fashioned dust shoe in place --- DONE!
- arrange and secure power cords, secure power strip --- DONE!
Remaining things to do:
- work out management for Dremel power cord and vacuum hose
- figure out how to invert belts on X-axis --- probably will do this by getting M5 hex bolts and grinding off a side so that they fit snugly against the side of the motor.
- make a nicer enclosure of Lego bricks --- need to hide away the wires for the p.s. and fan inside the enclosure DONE --- TODO add transparent bit for power LED, add push through stick for reset button
- replace remaining nylon spacers w/ metal, use 2" 7/32" roll pins as stand-offs for Y-axis motor (replacing 1.5" pins and 1/2" aluminum spacers) use 1.5" pins on spindle mount
- drill new holes in X gantry plate for second pair of bolts
- sound enclosure
- upgrade spindle
- replace standard carriage plate w/ steel version
- replace Z-axis delrin blocks w/ aluminum
- replace zip ties w/ cable drag chain
