From a sponsor I got a very cheap CNC machine. It's sold as CNC engraver (I guess because the mechanics is too weak to really route through a material...).
My part of the deal was to record a review video and I agreed to do so because:
-I was curious what this machine can do.
-It is a compact device with an Arduino clone running grbl, thus I can use the machine to test the software of my CNC 3.2 in my office instead of doing coding in my uncomfortable workshop.
-Cheap machines are meant to do experiments and to improve the design - tinkering at it's best!
-Compact, cheap machines are great to get young people in touch with computer controlled devices without being afraid they could break expensive parts.
Here's the video (more a general introduction in CAM than a classic review):
The output of my CNC v3.2 or 2.x is clearly better, but let's see what simple modifications can lift this engraver to a higher level of machining...
