Good morning Qtron,
I am sorry to hear about the troubles Australia is having. It is really sad that they have been catching idiots deliberately setting fire. But I know the character of the Australian people and they will pull threw. In my area we often have hurricanes so I know how disaster can take a toll on a nations psyche.
I am based out of Texas in the US. I used to be in the UK and go back when I get the chance.
First thing, the google automatic translation within the browser doesn't work anymore. What I found works is to go to translate.google.com and paste in the website that you would like translated. Another link will appear in the translated window and it will open the page translated in a frame. Navigation in the translated
page does not work properly if you just click the links. What I found that works is to
right-click the link in the page and select "Open link in new tab". Then the new page will open.
The number of trim-pots on the board is dependent upon what encoder you have used. If you purchased the encoder like an omron off of Aliexpress, then you only need the pot for setting the feed rate and contrast on the LCD ( to pin A7 on the LCD 1602 respectively). The trim pot for the LCD contrast is not on the Oil Major board. The following is the wiring schematic for the Arduino with the trim post that are not needed in orange and components other components in red which are on Oil Majors board if you didn't make your own encoder:
As to the multiple tabs in the Arduino project, when you compile the project and up-load it to the Arduino, they will all be put in there proper place. What Oleg did was break out each of the routines to make them easier to deal with for future modifications.
I figured out what the problem was with notifications on the CNCzone site; you have to turn on immediate notification on your subscribed threads under settings. At least that is how I think it works.
As far as the display goes the 1602 LCD is the standard. There were some who developed a fork for the software to use a TFT but I think that it isn't the way to go. Hear is a link to one on eBay that is typical:

They make them in a wide variety of colors and I picked up a large version of it.
I have downloaded the google translate version of the operations guide which you will find attached. In the translation the lathe chuck comes out as Cartridge.
On a final note, I tried to look at topic/11808 and that is not the correct topic; it comes up as a discussion on how to download all the Scientific Americans. Check the number and we can have a look.
All the best to you and all,
Bruce
