Impressive how clean it came out and even all the little holes look just about perfect!

Well, still making progress on the big repstrap thing. Its coming along, but there isn't much info out there on CoreXY design.. I'm looking for fundamental stuff like which belts have to be parallel, sizes of idlers, if they can be different sizes or have to be the same, and if so, which ones? I'm gleaning what I can from photos and random bits on forums, but I'm forging ahead either way, so it will be a bit of trial-and-error or a lot.

Here's a few pics of some stuff in mocking up, feel free to let me know your experiences if you've designed a CoreXY bot!

Look at my CoreXY printer there: http://www.thingiverse.com/thing:313095

The files contain the original model in sketchup. You can measure your heart out on the model. Precision is set to 0.001mm

Couldn't wait. Did a quick mock up of the +OpenBuilds V-Rail and wheels to see how it would look/work, and this stuff is awesome!
I can't wait to get it all cut and installed and start working out the bugs and gotchas. Hopefully soon...

HI! Hello!!

How do you wish to frame control rigidity during print head moving at high speeds?

Which make / brand kit is the frame?

Slowly but surely progressing on building this printer. Thinking of going with one of +Sanjay Mortimer's Volcano hotends on this thing considering the size. Most likely dual bowden extruders.
Built the bed support and got in the bearings and smooth rod for the Z axis. Put all the nuts in for attaching the motors and rod holders last night, just waiting on the right size screws to mount both of those.
Bed is reeeeally close to the 2' mark.. I'm doing my very best to make sure it's the full size.
Checked +OnlineMetals.com but the cost for a 1/8" sheet of 6061 cut to 25.5 x 25.5" is over $80 compared to about $45 for a 24 x 24" sheet. Might just have to bite the bullet on this one but that seems really steep.
Bought a couple sets of FSRs from +SparkFun Electronics and a couple ATTinys to see if I can build a little interface to make them simulate an endstop to the Smoothieboard for both Z-zero and ABL in case I can't get this huge thing perfectly flat.
Currently thinking up how I want to secure the alu to some mounts to make it easier to level. Possibly using some adjustable leveling mount/feet from Misumi.
The $20/4 set of 12mm LM12UUs from Amazon were utterly horrible. Almost unusable they are so rough on the rails. Gave up and ordered some $20/ea ones from VXB, along with a few extra bearings for various needs. They came in and they glide a lot easier.
Next up is to use my Fusion360 learnings to design an angle bracket to support the bed from the linear rods and get the motors and such mounted up.
Smoothieboard has been soldered up and I got in a ton of those little .100 female connectors and pins so I can wire up the machine really nicely.
If anyone's wondering, here's the current BoM for this printer:

It just keeps getting more expensive ;_;

having built and rebuilt a large corexy/hbot several times they are definitely easier to get the XY part done. The Z however is a whole other issue. However it is my main goto printer for large things. It currently has a 1mm volcano on it and can print large things relatively fast.

I'd like to see inverse ripple mode.

I suppose this is kind of like one of these printers, a big cube. I'm going to start with CoreXY and then if it doesn't work how I want, i'll move to something different.
 
Well I built the frame. Its huge! Got the other two printers there in the pic as well, the larger one would fit inside the frame I just built. It is rock solid and very sturdy, so I'm excited for some good prints.
Next up is to cut and mount the openbuilds v-rail and get the gantry designed as well as sizing up the z motors and rail system to get that aluminum ordered too. Hopefully some more progress soon!

Thanks +MISUMI USA for having some awesome aluminum extrusion frame kits available!

(2ft³ build area, hopefully)

WOW! That IS a huge frame! We're glad to be a part of your build. Can't wait to see the finished product.

Excellent cheesesteaks. The beef here is of the more finely chopped variety, heaped high. Sliced cheeses are mixed in on the grill, while whiz is poured atop after the sandwich is made. The rolls are absorbent and tasty. Tea is good and Fanta Birch Beer is even available at the fountain. Great sandwich for a good price!

Amazing experience. Best Tex-Mex/Latin I've ever had. Servers are very professional, very good service, top-notch food. We came here as a second choice, and it should have been first. I may not be very traveled, but this is a great local place and I hope they will be around for awhile!

Always good pizza downtown. Have never been let down by Flippers in general, and this one is no exception. Quick deliveries, great food.

We were looking for a place to get breakfast, and upon finding our usual spot already closed, we stopped by Elly's. The menus here are large, but this by no means affects the quality of the food. Best eggs I have ever had, and the blintzes were amazing. Will for sure be coming back!

Excellent experience here. Went with friends and used both the pistol and rifle ranges. Both clean, well-lit, and plenty of air moving around! Easy to get going, reasonably priced targets and range time, what more can you say?

Our favorite pizza shop. They always have quality food. Once we had an order show up with all the cheese having slid off, but a quick call and all was made right. They care about their customers and it shows.
