Aha. I see. So flip the belt, lower the idlers to compensate. Interesting, I didn't have the issue on Y - but I have dual belts there with my shaft drive. Let's see, how can I shore that up? 0) invert things, try to achieve improbable zen (0 is for convenience, not as an insult) 1) Bigger belt? swap...

The X belt is stock. I so have some custom belt holders on it, but they only have mild flex. How did you flip and keep enough contact? Also - thanks for the fast shipping! That nema23 kit fit very nicely! (The plastic bag was cut along the edge of the delrin part, but that was probably from shipping.)

I murdered a couple of steppers, including the wee nema 17 on the Z axis. After almost hacking out a mount from stuff in my shop, I decided to order the kit that improbable construct offers. (quick shipping!) http://powercordlabs.com/wp-content/uploads/2013/06/K-first.jpg This is the first thing I c...

I would consider making some lubricating wipers. Some felt padding on a v that cleans and lubricates the slides. Lube catches dirt, but you really need some form of lube with metal on metal.

The new bed has solved my alignment issues. It's all Mitsumi rail. If I had to do it again, I'd probably get 80mm tall for the machine outers, but I already had them. Here's the construction I used: http://biobug.org/lj/built-table.jpg And the entire machine - sorry I didn't clean up for a glamor sh...

IR blocking plastic is NOT expensive. I suggest getting some. Even matte surfaces can reflect enough light to cause damage. A good option is Lexan. You can get it at HD or online.

Did you just buy the metal v wheel and use your existing bearings/spacer or did you buy the wheel kits?

Dammit IC, I get busy for a few months and come back to find this. That is some fantastic work sir!

Are those shopbot/mechmate v-wheel bearings? Excellent! How are they working out for you?

Edit: Nevermind, I see, openbuild. Still, how are they?

I've been a little busy and ignoring my mecha shapeoko. However, my wife has some things she wants me to make, so I finally ordered a few more parts. Problems to solve: 1) Slop in the bearing design, I haven't decided what to do on that. Copper washers or maybe something else. 2) My work table isn't...

Those look very nice!
Do they seem like they'll hold up over time? Are they steel or aluminum?
