Hi. I'm working on this build for about 2 years now and jsut wanted to share some pictures of the progress.
The Framesize is 1000mm x 800mm. It is a direct driven dual drive gantry design inspired by the famous Gabriels build.
It uses 25mm linear rails on all Axis and 1605 ballscrews on X & Z and 2005 on Y. I wanted 10mm pitch at first but ordered 5mm pitch... and for now can live with it.
Motors are high torque Nema23 steppers. In the future I update to 400W Servos.
Everything was done with simple tools like a drill stand and a sliding mite saw.
This is how it will look at the end:
