Yuriy,
I love ya man! And I want to support you. That said, I'm a knob in the worst way when it comes to DRO's, and this whole "upgrade" business is unclear to me.
Dec 2022, I bought a fully assembled board, with "kit" enclosure.
DRO Adapter for Glass and Magnetic Scales V2
I've hooked up the unit, played around with it some, but haven't gotten my lathe fully functional yet, so I've yet to truly enjoy and learn the capabilities of the unit yet.
Does my unit qualify for the $25 upgrade? It was not "fully assembled" so I'm unclear. And if it is, what layman features does it add to make it worth both my and your effort to make it happen?
The one thing I'd like, is if the unit remembered the last know position if the TouchDRO is powered down. I think your newer units do this, but I'm unclear about mine.
Anyway, please forgive my knobness. I totally understand that you want to move away from guys like me, and get your unit targeted at guys that are pros, and more knowledgeable. That said, I love that you have supported the newbie's up to this point.
Sorry for the ramble...I suspect I'm not alone in my question, though.
