OrdBot users, what's your overall opinion?

I either have or can mill most anything I'll need to build an OrdBot. I also have an E3D Lite6 hot end waiting to be used. Those of you who have used OrdBots, what's your opinion? Weaknesses? Strengths? What would you change? Do you recommend it? If not, why?

I think it is one of the best printer out there. My son has the first one I made over 2 years ago and it still prints as good as new and it has done over a thousand hours of printing. I've built about 25 of them and have never had a problem with the machines mechanics. Now if you enlarge it any, I can give you some pointers where it need to be beefed up. The last few I've made where 300mm cubed.

Did you source your carriage for the hot end or make one yourself? The one that's L shaped.

Also, what's the max size you'd recommend with the stock design?

The table on the X gets a little wobbly if you try to go any wider. You could extend it in length and it should stay stable. I use open rail on 20 X 80 for the Y on my 300's with additional bracing for the Z.

For the carriage, I use two plates and bolt them to a piece on aluminum angle. On a few, I used a bowden setup and didn't need the bottom flat.
I'll post some pics later for you.

I'm still tuning and calibrating my Ordbot Quantum. Not 100% convinced the NEMA14 motors are adequate, but am probably going to try a different power supply first, then if that doesn't work, see if I can find some really good quality 400-step NEMA14 (or 17) motors (suggestions?).

I love how clean the design of the ordbot is. Thanks for the photo.

@will, I've noticed Nema 14 mentioned multiple times, but I assumed I could just use the 200 steps per Rev 17s I have on hand. Is that incorrect?

Yeah, the Quantum uses NEMA14s in its stock design --- I believe the Hadron goes to NEMA17s --- I've been considering swapping in a NEMA17 from a spare extruder on my Y-axis --- just needs a new motor mount plate.

I use .9 degree (400 step) nema 17's on the X and Y and use the 1.8 degree (200 step) on the Z. With these motors, I use 8825 drivers and I get everything I print to within 10 microns using GT2 belts. I use 10mm 2 pitch acme for the Z. All the firmware for 3D printing is metric and you don't end up having a partial micro step on the Z to worry about.

Here is how I did mine
