they look like 2mm screws
hard to find at most hardware stores in this area
I get mine on ebay and they are still scarce

even worse when a small motor mount uses them and you drop one

What is the strength like on those thin walled parts like the spinner? I've been struggling with thin wall parts (less than 5 perimeters) where the layers will separate when I squeeze them. Maybe I'm expecting too much...

sounds like maybe you need to do a bed calibration for nozzle clearance
when I had mine to high the layers weren't blending (Fusing) together enough

the first layer should slightly appear flat topped on the first pass

This is a problem for the Makerbot as well, so we generally print in PLA on that (Mkaerbot PLA is good up to 108degrees continuous duty operation). Further, the claims of the Lulzbots ability to print materials besides PLA and ABS are sort of a joke, at least if you order T-Glas and PC from the lulzbot site you need to bake the filament to remove water, otherwise you can't get a continuous extrusion of filament.

I also have experience with the Makerbot 2X, at least right now it blows the Lulzbot out of the water and is superior to the Replicator Dual for ABS prints. I'm not a huge fan of Makerbots practices or customer support, so we are looking at the Ultimaker 2 for a second printer to supplement. Any thoughts on that are appreciated.

Which model of the Lulzbot do you have?

Thanks,

Scott

That's happened to me on vertical walls. Went back to adjust the design so the thickness was a multiple of my nozzle.

It's been quite some time since I posted the last picture of my Printrbot Simple - almost 6 months.

It's a different beast now. Here's what's different:
- 6in^3 (with possibly more Z height, but limited by wiring) build volume
- 6x6in heated bed
- E3D V5 w/ v6 heater block - can reach 300c+ temperatures just fine.
- Bowden assembly to reduce weight on moving parts.
- Metal Z coupling
- Fully belt driven
