New to CNC, looking to learn

Hi

Apart from using a 3D printer my knowledge of CNC is pretty limited.

Do have a useful workshop with a Harrison M300, Warco Mill, MIG and TIG welders etc so comfortable making things, but electronics and CNC is all new to me

Acquired a Boxford 160TCL and 190VMC with auto tool changer probably 8 years ago but they have been sat under a dust sheet till now.

Intention was to convert both of them to modern electronics but work, DIY/car/van projects keep getting in the way.

I had recently started working on the 190 to understand how it works, give it a clean and get a shopping list together of bits I needed to buy, however, a Boxford 260 VMC turned up locally already converted and this will be my focus with the 190 probably going up for sale
