So, yesterday was a bit of a bummer when I discovered that the used Cheetah 1.1 controller card I bought from a dude on facebook actually was a dud. No signs of life at all and the uP onboard gets super hot from just applying USB power.. So I went ahead and ordered a new controller for the plasma.. That’s all in the electronics department though and the plan was to get the mechanics finished this week.

So, I needed some spacers for all of the idler pulleys. Didn’t have time to wait for an order so I manufactured these 5.7 and 1.0mm spacers from a spare piece of 6mm aluminium sheet.

After some filing they turned out pretty decent. It’ll have to do for now.

Since I didn’t have enough 2040 profiles I decided to go with some 4040 extrusions for braces instead, so I had to re-mill some brackets to fit.

I made these from 8mm aluminium, not that it’s needed but with M12 bolts it just felt better. =)

So these are all the parts that I made yesterday.. As you can see I made new mounts for the Y stepper motors to accomodate Nema24 motors instead of the Nema17 for which I didn’t have any pulleys.. so, today I’ve got to make some splines in the belt wheel for the E-vant project and then the last of the mechanical parts are going together on the plasma.. We’ll see how it goes.

The black rectangular thing is the 3d-printed electronics box that’s going to house the Raspberry pi and the controller board, more on that later.
