1st-I have a crush on amazon.ca.
2nd-Mounting plate looks perfect.

The race is still on, CNC64/CNC86 are far from finished. By the time your machine is up and running, you'll be able to cut all the panels for dozens of my machines before my MDX-3 would have the time to cut a single large panel. ;)

All the parts for the NEMA 23 stepper motor assembly are ready, except for two coats of paint. All that's needed to upgrade the Y axis to belt drive is the plate for the other side where the idler pulley will be installed.
2014-05-13, update 1: I just ordered F686ZZ flanged bearings to make the belt idlers. That's another delay of two three weeks. :cry:
2014-05-13, update 2: angelinvestment2010 has already shipped my flanged bearings. This guy is fast! 8)
2014-05-16, update 3: the tracking number for the package still hasn't shown up in China's postal service database. :(
2014-05-19, update 4: "International item has left originating country and is en route to Canada"
Yvan256:
If I'm going to wait for the F686ZZ flanged bearings to get here, I might as well cut panels in advance so that I'm ready when they arrive. I might even find something else to use temporarily in the meantime.

Since I need to cut new plates for the Y-axis for the belt drive, I've decided to try to fix the bushings alignment problem.
Lucky me, the new design for the part "Y1" fits four times on one plate.
The new Y-axis assembly design has seven distinct parts, with four plates having one bushing each. Two top plates will then join the front and back plates+bushings and the left and right side will be joined together with a plate with slotted holes. The end result is something that can be easily aligned after assembly.
Here's an exaggeration of the "sliding" design that should allow perfect alignment with the Y-axis rods. We're talking about plus or minus a fraction of a millimetre here. Alignment has to be perfect, as I learned the first time around. Those bushings are extremely precise.
And here's the four Y1 plates with their bronze bushings.
Belt attachment design and three more plates to go.
Yvan256:
If I had started cutting panels this morning instead of this afternoon, I'd be almost done with this... :(
Oh well, here's the almost-first-half of the new Y-axis assembly.
Half-enjoy!
P.S.: the next post should bump this thread to page 6, I'm probably not the only one who's tired of downloading all those old photos from months ago. ;-)
