Looking for advice, I have acquired a Cam Tech laser etcher with a 1400mm X 1200mm bed it's approximately 20yrs old. It has been in use but I would like to update it. Don't know much about these things,the software has been updated but I was wondering about the cost of updating drives, steppers, motors ect. Could someone point me in the right direction or list the components required. Sorry if I'm being a bit vague but as i've said I'm totally new to this. Many thanks Gary
