It will be cast solid aluminum which is the only real solution for the rigidity issue. If you could do it in cast iron it would be perfect. However this seems to me to be the best compromise after a lot of thought and trials.
This is a moving table design not a moving gantry design.
We plan to make the casting sometime after the 6th of January when I have help from the rest of my team here working on another project.
Great to see more progress! I
Is it just me or have we (maker community in general) seen the peak of the "Build your own CNC" movement/trend?
Or has it just been shifted over to the "Buy/Assemble your own 3D Printer" movement/trend?
Just wondering when Goodwill and other thrift stores are going to start having piles of 3D printers and CNC routers looking for a new home?
What did the tool handling end finally look like?
(I suspect you will be posting that soon enough)
Here is the first part! It was perfect until the last pass Mastercam tried to do some kind of scallop on the holes on the finishing pass for some reason I have to figure that out. Tool holding is ER 11 which is max 3/8 tool. I have the vfd set to 7200 RPM I still need to hook the spindle control up to Mach 3.
I'll do a video as soon as I fine tune the machine I have to hand scrape the ways to get perfect alignment and be able to tighten the gibs fully. It does cut Aluminum and even Steel passed the first test. But I want it perfect before I do a video ; )
