Wow, been a while since Ive updated stuff.
Got some 12mm YZ plates laser cut from acrylic
Just spent a couple of hours tapping 32 holes for M3x0.5 threads in preparatuon for rebuilding the LR3 again.
So I updated the size of the access holes for the M5 screws to the beam, so it should allow removal of the screws all the way. On the advise of the person who does the laser cutting, I eliminated sharp corners, both interior and exterior. Some of the features seem a bit weird that way, but the overall pieces look nice.
I specified the rail holes as 2.5mm, and it took the tap well. The holes look frosty now, of course. I also added 2 holes to mount my LCD for the Duet on one piece only. I hope the threads are good enough to securely hold the rails. Even turning the tap by hand it got quite hot, and Im not sure how well the first few theeads formed. I hope that I don’t need to go to 18mm M3 screws and use nuts, as it wouldn’t look as nice.
