Routy GT2 290 BSX CNC Router, Low Cost and Good!

So you are looking for a project to start with? It must cut most soft materials and even up to aluminum when needed? Cutting area of 300*320mm (11-13/16*12-9/16") should be enough? Then look no further! This small Routy CNC Router has it all!

OpenBuilds México has been working on small CNC routers since the beginning of this year and thus we know what a small machine like the Routy GT2 300 BSX CNC Router can do. For now we only will show you a completed build of it but in the next days we'll post the build-manual, schematics (Arduino), setup values and tips!

The Part-List only included the mechanical part of this machine, you need to add:

• 12 up to 24vDC Power Suppy, recommended in the range from 300 to 500W
• power-cord for the PSU (Power Supply Unit)
• Arduino Uno, even a clone can be used, needs to be flashed with GRBL
  • Set for X and y axis speed to 5000mm/min and 50 on aceleration, steps per mm at 57.14 (make sure your shield is set at 1/8 step)
  • Set for Z axis speed to 2000mm/min and 50 on aceleration, steps per mm at 200 (make sure your shield is set at 1/8 step)
• GRBL Shield v3.x, recommended to bridge the useless fuse on the board and use an external fuse if needed, use DR8825 drivers! 1/8 Step needs to be set with the jumpers, also 2 jumpers need to be placed to clone the Y axis to the A axis! Drivers can be set up to 1.2A (or leave them in the middle with the pot-meter )
• 4*4" (100*100mm) plastic junction-box, used as housing for the Arduino, you can use double-sided foam tape with a some spacer-block made out of wood or plastic. Just make sure the block isn't to thin else it won't let you plugin the USB from outside the box. If the spacer-block is too tall it will not let you close the box.
• 80mm fan with the same voltage as your power supply, use four 6mm low profile M5 screws to mount to the junction-box cover (tap before you screw)
• 2 extra Low profile M5 8mm screws to mount the junction-box to the back of the X-axis
• A bunch of tie-wraps, black or colored, not transparent (they break too easy from UV-light.
• Adjustable Strapping Clamps that fit your router or rotary tool (Dremel 3000 used as an example in this build)

The total cost of the mechanical kit should be $ 445.45 USD + Shipping!

For now we'll show you some pictures of a finished machine:




Note that the wheels used are not all the same, this was done just for demonstration purposes. Instead of 10 Delrin V-wheels and 6 Solid V-wheels you can get a 20-pack for a few cents more and have solid wheels for the whole build plus four as spare!
