Some pics of machining pulleys for the HTD 5mm x 15mm belts. 60 tooth is 6061, 18 tooth is stressproof steel. The small sprocket was then heat shrunk onto a hub with one integral flange and outer flange staked on.

Gantry and Y-car.

Paint job (John Deere construction yellow!) and reassembly. I'll grab some more photos and post again soon.

A few more pics of the pressurized control box with Dell 280 built in and the low buck cable carrier setup. I didn't have any luck sourcing any Igus type carrier locally and ran out of time.

A few more showing slat details, Y-car and torch holder, gantry drive, and it sitting in place.

I did a few test runs on some lighter material and with the exception of me needing to learn a few things about Mach3 and Sheetcam, everything seems to work great.

It is easily capable of rapids of over 1000 in/min and will accelerate in excess of 200 in/sec^2. Despite being single drive, the gantry is very rigid because of the long X-car bearing spacing and light weight of the gantry itself.

Come on guys, I'm looking for some criticism or some tips... anything!
