Lathe project needs a turret was created by CaliusOptimus
Hi all, new user long time lurker. My first linuxcnc experience was a sherline and a parallel port some 10 years ago. That turned into a pair of tormachs, now a vf2ssyt, and more if I had the space. Anyway...I picked up this lathe some time ago. It was originally cnc and converted to linuxcnc by the previous owner. I got it in a sort of working state. Everything was hooked up and moving but needed some refinement. At some point the PC died of unknown causes so I decided to start from scratch with trixie, kde and 2.9.6. I've got the servo thread running solid at 0.5ms, the motors all tuned and running well, the spindle drive is now controlled through modbus rather than analog, and I've added a few handy things with pyvcp. It's running fast and holding size.Now it's ready for a turret, and I'm hoping to get a recommendation. I currently have a neat manual turret but... manual is no fun. I've browsed alibaba and seen some affordable options. Also checked ebay and the pickings were slim, ancient and beat to death. I considered a tormach turret since it works so well on my sl15 but it would be nice to beat the $5k price tag.Also searching for an automatic collet closer or some sort of automatic chuck. It would be amazing to have a 16c or a 3j automatic collet... sounds like a huge amount of work if I can't find something to retrofit. Any ideas?

The manual turret looks like a prime candidate for motorisation...
Or get an industrial robot arm to operate the manual tool changer for you.

@CaliusOptimus, check out the ALTAROS Automatic Turret Head:

CNC4XR7 on YouTube installed one and has a few videos on it.

What a neat little turret! Cool company too, I've got one of their booster pumps.
That turret is too small unfortunately. Will be taking some decent cuts on this lathe so I ordered a tormach turret. Pricey, but those guys are so great with tech support... one call and they were willing to explain all of the electrical details I needed to integrate it.

First real job for this lathe-
Parting off from a 4" 304 bar, then facing back side of the part.
Had some extreme and abnormal chatter at first so I looked around for loose components. Tightened up the X gibs, tried again, nope. Put a bar in the chuck and an indiciator on the spindle, gave it a push and a shove and saw .004" TIR. Ended up having to tighten the spindle preload and good to go.
