I'll put all the details in the build. I've been planning, designing and collecting parts for some time now, probably 12 months or so at a guess. Probably not quite that long though.
v rails are bought ones with matching V bearings, those bearings are bloody pricey! unfortunately I'll need to replace 6 of them at some stage as I didn't specify seals and ended up with metal shields instead.
The reason I purchased the rails was to keep the weight down on the gantry, I could use angle but wouldn;t feel confident in getting it straight, I could mill something but wouldn't feel confident resetting the piece to mill subsequent sections beyond the travel of the mill. I could build a fixture to make that process easier.
But I'm lazy
I've got one of candcnc's MP3000 torch heigh units. you can get away with no height control but if the piece starts warping when I'm not looking, I'd rather the Hypertherm torch not drag on the material.
I've also almost completed a torch breakaway in case of any collisions.
I'll snap a few pics tomorrow and aim to start a build shortly after.
