Re: 1200x1200 build/mod

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...

Re: 1200x1200 build/mod

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.)

Re: 1200x1200 build/mod

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...

Re: Effect of metal wheels on makerslide

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.

Re: 1200x1200 build/mod

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...

Re: World's slowest laser cutter

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.

Re: Is this thing even a Shapeoko anymore?

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

Re: Is this thing even a Shapeoko anymore?

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?

Re: 1200x1200 build/mod

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...

Re: T-Track Hold Downs

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