Whats the difference with the Y support 1.0 and 2.0 and the Corner 1.1 vs 2.0?

They are both pretty minor differences.

Y support 2.0 has proper clearance for the bolt head that mounts to the openbuilds rail. 1.0 doesn't have clearance at that location. Corner 1.1 was slightly too tall on the top, so the plastic sticks up about 3-4mm above the openrail. THe 2.0 variant is flush with the rail which allows for closer bed tolerances.

I still have Acrylic Y endplates available if anyone wants a set.

Thanks for the mods, piercet! I used your "3mm" etched tall extruder body from thingiverse too.

The Y-axis looks great. Because of taxes and work, I haven't printed yet -- only ran a couple tests without filament.

I have printed after completing the X-axis mod installed and it was super smooth.

I did have some minor issues with both builds, but nothing major or different from what was already discussed.

I've been lurking on these forums forever... decided to finally post something. This is my Kittaz

That turned out great! Nice work! I like the Noctua fan on the extruder there too.

I can once I get my router back running in a couple weeks. Really though, I think the acrylic will be great for this application. I'll post the dxf also so anyone can make their own.

Discojon - Would it be possible for you to post the .stp and .stl files for the combined end plates at your convenience? Thanks for your hard work on developing the files by the way.

From what I recall I designed it in sketchup. So no STP files unfortunately.

About to finally move on this upgrade and just want to clarify a few things:

The BOM says 12 T-nuts, but in the pics it seems like there's more than that. Can someone confirm the total amount?

I have some M5 11.1mm heat inserts. Will those work, or do I need the 6.75mm?

I've never used a tap before. Can you confirm this would be the easies to buy for this project? http://www.mcmaster.com/#8305a16/=12d9cpg

That's all the q's for now. Excited to get this installed. Thanks!

That tap will work, but I like this kit at home depot/Lowes, etc. It's 4x as much as that single tap ($30), but this also has the drill bits, dies and taps for 3, 4, 5, 6 and 7mm. So it's really handy to have around for other projects and a better value.

The BoM assumes you will reuse the stock T-nuts. You will need 2 per support strut piece in addition to the stock ones, 6 pieces total, for a total of 12 additional M5 T nuts. I also might be forgetting about the upper ones on the corners, which would be another 8 . With the stock T-nuts you require a total of 8 +8 +12 or 28 total.

That tap will work fine, if you are doing the modifications anyways, you may also want to buy an M3 tap and do the holes for the retrofit Nozzle wiper M3 bolts at the same time http://www.thingiverse.com/thing:1261303

The 11.1mm long heat set inserts are a bit narrower at the bore than the shorter ones, so they may not lock in as well. Try one, if it doesn't work let me know and I'll make an stl file with slightly smaller holes to compensate.
