Nicely Built Hobby Tool

There is a learning curve, but Comgrow has created a nice hobby tool with many possibilities, sturdy build, and options for upgrading. This is a great tool to begin learning CNC routing.

Great Code!

This is a gift, so I won't be using it, but the code worked great and I really appreciate the savings!

Neat machine

The machine is nice and the price is right. My electronic board might not be working correctly because candle disconnects after a few seconds. I keep getting "serial device not available" errors from candle or universal g code sender. I'm replacing the electronics with a different board anyway, so it's not an issue for me.

love this machine so far.

would be good if they added an option for an upgraded z axis to ship with the machine. love this router so far, fun to mess with and make some projects.

shines when placed on a concrete paver with foam under the paver.
