and it could be quite thin, 3mm would be more than enough. the device is small-ish, so the price of the metal isn't the isue the nice solution would be machined aluminium !- tjtr33 has joined #linuxcnc way too heavy for a kit, and i need to mount the rest of the stuff somehow. Cheap would be granite worktop, double-sided tape and those IGUS slides. 20cm granite kitchen worktops are even cheaper 20cm granite surface plates are inexpensive I reckon you could have an iron casting for the base for £20 i can't imagine that would be anywhere near affordable in small-ish quantities I think MattyMatt (who is probably asleep) built a drawer-slide milling machine i would love to use a solid metal base, but it would become too expensive to manufacture a lot of early diy 3d printers and such have used drawer slides. I've been tempted to try the drawer slide thing, see exactly *how* bad it is base will be some type of wood, probably phenolic plywood/multiplex stuff.

I now go as far as providing a working reference design that people are free to corrupt with drawer slides, hot melt, connectors and twisted rods from the hardware store unless the undercarriage goes across both sides. Unless the rail and base are made out of very different materials, that will be fine. Leave the screws loose, slide to one end, tighten screw at that end, slide to other end, tighten scres. !- Simooon has quit I think you might be worrying too much about over-constraint. unfortunately, the cheap chinese sources of those hiwin blocks do not actually provide specific model numbers i'd rather not have people start grinding bits well, this is going to be a kit for people to build But why not slide it in the appropriate channel, and relieve the sides if you want to be sure of no over-constraint? Topy44: This expects to fit inside a channel, but doesn’t have to: right !- tannewt has quit C, H and P, 10um, 10um and 5um for 200-250mm length rails i _assumed_ that would be something you could buy. made from something like the stuff that igus uses for their plastic bushings i would like to just use a gliding block on the second side
#Ecut 6 grbl code
the product code contains a "preload class" !- rob_h has quit Because they are preloaded, so no play, but for a given force they will deflect If you see anything at all it will be a stiffness !- syyl_ has quit i was thinking of using something like this: it has load ratings but i can't see any accuracy ratings Back that is, which types are built to be rotationally accurate in that direction
