The GCC was a great laser and one of the early machine you could sensibly buy.
It uses a CO2 sealed RF (not fibre) air cooled source.
A repalcement Synrad source was too expensive so the project was to convert the whole machine to run with a Ruida controller and a spare 60w tube I had.
I also had a chiller, (I thought I did), Laser PSU and some steppers, connectore and wire.
I had to buy 3 Stepper DM542 controllers, 24V 3A Power Supply, CO2 Tube Mounts and a used Ruida RDC6442S-B controller and screen panel.
Out with the old Laser source, main board, power supply, and the two drive steppers as these had encoders and the ruida wouldn’t drive them.
A bit of cutting and small adjustment to get the two KH56 stepper in, think these came from an old photocopier. The stepper to raise and lower the bed stayed.
I wasn’t sure about steps: Steps per Output Rev = (Total Motor Steps × Driven Gear Teeth) ÷ Driving Gear Teeth and if I was using micro stepping or what so just left it.
Turns out using Lightburn and the simple steper calulator in there sorted it.
It’s quite a long path for the laser beam as sits on the rear floor, with the mounts fitted I had to increase the height of the first laser mirrors and red dot injector and would of liked to of gotten it much closer.
Setup in Lightburn and works great, it’s used every working day at the moment.
The CW-3000 passive chiller had a leak so I gutted an old dehumidifier for it’s internal piped and that worked great, in fact better.
