This is a major update.
The machine is working!
I'll start off from the last update. Here's a photo of the crappy, warpy, gluey, recycled stainless that makes up this machine.
Chopping it up with a Dremel saw that uses cutoff wheels. Mostly because I don't have a sheer.
Then I flatten it as much as possible and use a hand belt sander to get the brushed finish.
Afterwards I bend it on my little box break, and weld it with my Dynasty280x I love that tig machine!
More sheetmetal work.
I printed a cable dragchain mount that l's off for the x axis chain.
Unfortunately it was in the way of the connector used on the back of the turret so I had to redesign something that was much more compact.
I decided black could look a little nicer instead of the blue. I also made a nice little stop for the home switch on the Z.
That was one tough insert. G0 Y not Z while machining round tool holders.
Here's one of the internals of the turret. I ended up using a Leadshine closed loop nema17 stepper instead. The original stepper wasn't powerful enough to make it all happen with only 1.2A max current. I tried a 5:1 geared stepper but then there was too much backlash and the turret was missing the teeth for engagement. I also printed a really tightly toleranced pulley and there's only about 1 degree of lash now.
Round holders are finished and I drilled/bored the hole on the lathe itself.
The seal is printed in a TPU and very flexible. It'll be hard for chips to make their way into the hirth I think. The top of the turret was blindingly shiny I had to cover it with a little vinyl.
The router had a really really hard time cutting the 300 stainless. Even with MQL spray, perfect chip calculation it was really hard to get a clean cut.
It's really starting to look like a machinetool!
I successfully implemented an M6 remap today and the turret works perfectly. It even errors if it doesn't make it to position.
I'll be posting my complete config files for linuxcnc with a 5i25_7i76 setup. That will probably happen over on the linuxcnc forum so if you're interested I'll link it when I get that done.
That's all for now.
Next steps are to cut some metal for the coolant system. Then learn how to turn parts via fusion360.
