Where to buy scales?

WobblyHand said:
Since I embedded the display into my lathe's electronic lead screw (ELS) display, I had no need for another display unit. So I just bought the scales only. As soon as I received my scales, I tested them using my ELS controller. They all worked so I did save some cash buying from AliExpress. eBay is pretty good at times, but with all of these kinds of places, it is worth shopping around.

which els do you have?

Made my own. Using a Teensy 4.1 as the controller and a touch panel display. Designed my own PCB and had them fabricated. It integrates the Z and X DRO information and displays both on the touch panel. More info at https://www.hobby-machinist.com/thr...ad-screw-controller-using-a-teensy-4-1.99609/ . I could explain further, but the info is in my thread in the forum. It's not CNC, since I didn't design it for that purpose. If you want that then maybe grblhal is a better choice.

Thanks
My friend and I just designed and fabricated the cheapest possible machining controller with an ESP32 on a custom board with LCD and EC11 encoder wheel. It reads rpm and calculates surface feet per minute, and feed rates from chip load info

next we were going to try ELS to create smart lathe out of my colchester chipmaster lathe. Make small production runds of tiny parts go faster

That ought to be fun. Good luck with it! I went with a cheap touch panel display and soft buttons, because I didn't want to be stuck with an inflexible interface. The downside obviously is the touch and display code, which can be a bit tedious. Basically, the user interface is a bit of a drag to implement. The main application is a lot more interesting.

I want one of the nice new and BIG GUI displays, or control from tablet wifi or bluetooth. I now have a surplus samsung tablet wasting away so that would make sense. Then anyone else could copy that since my friend wants one for his 10x20 lathe

The larger displays are nice, have to admit. At the time, I didn't want to invest the time into doing the network interfaces, although I have done them in the past. In the old days I coded that stuff from sockets, didn't want to bother with it this time. What I have is functional, and that's fine for now. Be interesting what you come up with, please keep us posted.

I will let you know...

I'm going to read your thread from start to finish and then Greenail's since his seems hardware closely mirrors my buddy's preferred option. Of course everything is subject to change at this point.
