I recentley bougth a started cnc router project for a god price on fb marketplace.
the machine was a bit bigger than i thougth. the machine is bassed on a moving gantry and two ballscrews connected with a belt to be driven by a single servo motor.
A big motor to drive the axis was included and some smaler nema 23 servomotors for the other axis. but no drive electronics. the z axis is quite tall and seems flimsy to me compared to the rest of machine round supported linear rails there. the original designer / builder of the machine is no longer alive so i do not know what it was designed for.
the plan is to use a mesa board and get some new servo motors to drive the x and z axis and likley run everything with linux cnc.
for starters i will use a 2.2 kw chinese spindle since i have one at home already. then i will probobly upgrad the z axis with some square linear rails and maybe a beffier plate.
any suggestions would be nice and also if anyone could have a idea what the original designer had in mind.
all i know is that he was an enginner working @ hagglunds (now BAE) and built the machine in their shop
for now i keep it in temporary storage becus i will get my hobbyworkshop in december. it's a bit to large for my 2 bedroom apartment =)
so i will hopefully get started with it after the new year.
