Hey,

I just gave Johnston a call and they gave me a quote over the phone. They have all kinds of plastics.

I never did a build log, and I'm still fine tuning. I am actually using the machine to re cut all of the gantry parts and using HDPE adjustment blocks. The machine is bang on on the ends, but seems to go out about 1/50" in the center due to flex. I'm hoping the new gantry and adjustment blocks help.
