Itchy – designing the new head

I tore apart the head on Itchy today, to start the rebuild. I want to have the plate that’s attached to the gantry, and then the plate that arbitrary heads attach to. Between those I’ll have the linear bearings, and if I stand the bearings off a little from the gantry plate, I’ll have room to put the lead screw down between them. In the course of this, I became a lot better at putting 0.5mm balls back into the linear bearing. I also got really good at cutting the same part several times and forgetting the changes I had mad and failing to update files properly. Then I remembered to eat.

Then I realised it was 9pm and went home. Fuckit, life’s too short for sleep anyhow.
