Schaublin 125-CNC retrofit.

Thank you for all your content. What are your plans for a user interface panel? You need to have potentiometers for feed and speed overrides, and buttons for cycle start and feed hold. Here are some photos of what I’ve done, and what I have planned on my lathe.  It’s a copy of the Fadal control. In the garage. I prefer physical buttons in the garage machine shop. A mouse or touchscreen just feels cumbersome when wearing gloves.

Thanks for the inspiration.
I use Gmoccapy, so I am going to duplicate the soft keys with a set of physical buttons around the touch screen like I did on the Maho. This will be up in the same place Schaublin put it. It will get a dedicated keyboard, which I already bought.
The soft keys of Gmoccapy already covers the start and feed hold buttons, but I might well duplicate them onto the pendant. Especially feed hold is very handy.

I will do a pendant down the front with two jog wheels dedicated to X and Y.

Definitely encoders for Speed and feed overrides, and jog speed. I will probably do physical buttons for the tool changer, and pneumatic tailstock clamping. Also the gearbox/back gear and variator might needs some love on the panel.

I need to collect my thoughts on this.

OMG I cringed when I saw you starting to knurl with that floppy old thing.

If you must use that pinch holder, add a spring over the top arm to it to keep it centered(ish) and engage in X next to the shoulder then move Z+. 

• Engaging in X means it's more likely to self-align, and
• You can easily check the Z- clearance during program prove-out

Yes, it's more money... but cut knurls are the ticket for CNC.  It's pretty easy to buy a single wheel and make a holder with a thrust bearing like this:

 

Single pressure knurls don't work great on flexible materials like in your vid, but they're nice as you can very easily adjust the knurl depth in G-code or tool offsets.

As usual, thanks for the vids.

It was a cringy moment. I should have programmed that knurl as a multistart, coarse pitch, LH and RH thread.

I have added a joystick with rapid for X and Z and 2 jog wheels for fine adjust. I tried the whole pendant thing, not a fan for the lathe. Also my controls are just outside my chuck to the left. Once I get the new panel up and cleaned up versus my current hack job while waiting for material I will post a vid.

I see you have a tool changer, very interested to help you get that working. keep the videos coming too. good stuff

By pendant, I mean a pair of dedicated handwheels mounted to a housing down on the front rail which the machine cover runs one, down on the stand,  like Schaublin did on the 125CCN. I only used one jog wheel with an X/Z switch on the mini lathe, and found it to be a PITA.

I saw you are working on a universal tool changer comp. Nice one. I will need to strip down and clean all the schmoo out of my tool changer, but think this is a prett simple one, with only a single control (Pneumatic valve for next tool), and two bits of feedback for the four positions. I haven't really got into it yet though.
