PS: What code are you using for your programming - I will get Tom Herbst volumes out and... time flies?

Ardurino... but which board and program?
Encoder code has evolved from Tom Herbst Volume 2 book, page 406.
I have developed my code from MB's code, which he in turn based on the book info.
The code we use is written in C++ language.
The best way to get started is read the relevant section of the book, then read the MB Encoder Mod thread on this site; based on fitting an encoder to a Gemmasta machine. https://aussielapidaryforum.com/forum/index.php?topic=4997.0
And more recently, Faceting Frank's current thread, he's smashing the coding and micro-controller learning curve!
https://aussielapidaryforum.com/forum/index.php?topic=7057

We're generally favouring ESP32 boards at the moment, that is boards with an ESP32 micro-controller on board. They can be had pretty cheaply, and have lots of functionality.

Thank you RC - found my Tom Herbst AGF VOL 1 & 2 yesterday afternoon - just looking to put together a kit or parts list with the latest evolution and see what can be done without affecting my fun. Like wooden boats some projects become all work and less play than expected. Much obliged - I will it seems have the room to put a table on MB's supernova - love this pale blue lab created Zircon from Pnom Penh - the blue is underwhelming and almost white.

Partly answering your questions, you put on my picture Alaskan.
The board I’m using is. NodeMCU-32S ESP32s development Board for Arduino and the screen is a 16x2 LED. The screen is very basic but both it and that type of board are used in all the YouTube tutorials I’ve come across. This makes it much easier to follow their instructions and learn how to write code and wire it all up.  I got all my stuff of eBay and I will make up a list of all the stuff I currently have.

Again thank you Frank, this is great! I'll get the list, collect the parts and focus on how to revamp a Patriot 8 into a 100 + facet stone cutter! MB's supernova is shaping into an eye-tickler - makes my pulse jump every time it comes up for a look-see. Tom Herbst Vol. 1 & 2 are challenges to my 80 year old brain but not the first time editing a sleepy curiosity. Thanks for the foot up! 👍

And thank you RC... "Fish on!!" Your https addresses are a gold mine. I'm hooked! 👍

Have put the info on the parts I’m using Alaskan on my thread.

Got it - thank you Frank, something else - been wondering about - my platen to mast clearance across my 8" Corian. The stone to lap contact is higher on one 1/4 (side) then as the sweep passes the halfway sweep the contact reduces to minimal. Talked to customer service at Patriot 8 and was told the perfect platen would be called a 'block.'

My work around is using the 25% of the lap where contact is meeting the set angle to maintain a level cut - center to edge. It's working and the entire lap is getting used so... is this abnormal or all that can be expected? Perfection would be equal contact sweeping full arc - is this expecting too much?
