Big Red 2.0 with perspex sides, MDF Spoilboard and full aluminium construction with the Y Axis linear bearings upgraded to fully supported rails.
The beginning of a quick test of the machine using a pencil to draw Sweet Dreams with a heart ether side which i plan to engrave in some perspex and side light with a few RGB LEDS.
End of test
I`ll add descriptions to the pics soon but basically the little black block is a 1.4w 445nm laser diode that can be pulse at 2w and i have added a vacuum system and the thing with the copper wire wrapped round next to the router is a small camera to help with alignment of the tool. i still need to get the aluminium plate for the front, back, part of the Y- Axis and all the parts for the Z-Axis milled but for now the Big Red has no problem cutting wood and plastic.
i am currently running the motors at 24v 4A but i have still to fit a couple of boost converts to kick the voltage up to the max the drivers can comfortably handle of 40v 4A which will help increase the speed. i have already had the Y Axis running at 3500 mm/sec which is about 137 IPM but for testing i have been running at between 500-1000 mm/sec 19-39 IPM to make sure i dont kill it with one wrong move.

- 960w 24v PSU worth over £500 that i picked up for £30 on ebay int the small hours of the morning
-
- I have now added fans and covers to keep the driver cool
-
- USB keypad used to control the machine until i build something better
-
- i placed some magnets on the back to allow me to stick it to stuff
-
- 1.4W 445nm Laser which can be mounted to enable laser etching and cutting of thin materials
-
- dust guard and vacuum system
-
- the copper was temp holder while i aligned the camera
-
- An old bagless hoover is being used for dust collection for now but i will be making a cyclone dust seperator at some point.
-
- An old TV bracket with a shower rail bolted on so the vacuum pipe can move with the CNC
-
- The Super PID router speed controller is now mounted in a nice abs case and all the cables are now run to allow control of it from mach3
