El Beast - Initial design phase, comments and critique welcomed!

Back to the build!

So had a chance to make my rail alignment doohickeys:










My plan to cut them so that the critical height is on the same part of the ballscrew seems to have worked well:

13.499mm



13.500mm




Biggest variation i found was 13.497 to 13.503, so max variation of 0.006mm (0.00024 inches if you are that way inclined), so pretty happy with that.


I 3d printed a jig and made some drill bushings on the lathe, looks like a shocked robot:



After drilling, tapping and a quick de-burring I gave the 20mm bed plate a good clean and laid the machine down on it upside down. Wiped each piece and area with an alcohol wipe to try and minimise any dust or dirt before fastening the rail spacers into position against the bed plate as a reference.





Then finally gave the rails a good wipe with a vanguard anti-corrosion wipe (hopefully minimise any naughtiness between the steel rail and milled aluminium mounting surface) before mounting them against the rail guides.




Next up will be re-making the front plate after my motor mount height snafu, then I can crack on and get this lower frame finished off before moving on to the Z-axis next.

0.006mm!

Excellent work I guess you don't need to write in your ebay descriptions please allow 1-3mm for measurement errors lol.
