Hi Keith, I also found the same problem on z-axis tops.stl , z-axis brackets.stl and z-axis bottoms.stl. Like I said I can fix mine just wanted you to know.

Hi Keith, love your design and I'd like to build a 200 x 300 bed version. I have a question :
Is there a way two split up at least the y-center.stl so I can print it on my 220 x 220 buildplate ?
Thanks in advance.

 

Never mind, I found out how to do it.

 

In the final stages of my build

 

Just figured out how to extract out of SketchUp

mine will be for a plate of 250x250
the more I look at this printer the more I like it a lot

I'm building 2 TrueUp Bold printers following your instructions. I have a question about the bed and in particular, how the heated plate and glass are kept flat.

The bed is 300mm and it appears from the instructions that the plate and glass are only supported on the corners. This leaves the entire center of the plate unsupported.

How is the bed kept perfectly flat? I seem to be missing how the middle of the bed is supported.

 

Hi Keith, It's been a long time but everything is coming together rather nicely. 300mm x 300mm x 500mm I have a question about the Z screw going through the bottom brackets.

In my mind from top to bottom through the bracket: top lock collar , top recessed bearing, bracket , bottom recessed bearing, bottom lock collar, pulley.

This is how it looks to me in the sketchup. So I'm not sure where the 8mm washer needs to go as the lock collars should only be engaging the inner race of the bearings.

I understand the need for the washer if the pulley is being used as a replacement for the lock collar. Then it would appear to be from the top:

Top lock collar, top recessed bearing, bracket, bottom recessed bearing, 8mm washer, pulley.

If either of these is acceptable I'll probably go with the bottom lock collar then I don't need to use the pulley for anything other than it's job.

Sorry for making this more complicated then it needs to be, just want to get it right.

 

Has anyone other than Keith completed this build?
I'm thinking about stating this and wanted to see if anybody had any comments +/- for their builds.

 

I probably will eventually buy a new one, but I have pretty much all the pieces laying around from various other projects anyway.
I have a Tevo as well, so printing the needed parts won't be an issue. Just an interesting project ...

I think the CR-10s is too big for my needs. I rarely print anything that big.

 

It started out as a Tarantula, but little is left of the original. Upgraded to dual Y rods w/ AL bed and dual Z. Also added a BLTouch.
Why not the Bold? It's looks well thought out and sturdy. I was actually going to incorporate a few features of the LZ into the Bold.
Do you recommend the LZ instead?

...I think I'm going to do the LZ

I was just looking at the CR-10s Pro, perhaps I'll get this.
