F.A.Q.

Here are some frequently asked questions about the MDF3790!

Although it has been a few years since I built my MDF CNC, The cost breakdown was relatively easy to remember! 5,4,3,2,1 That is about...

$500 for the electronics (motors, controller, power supply, etc...)
$400 for the hardware (fasteners, bearings, angle)
$300 for the lead screws and nuts
$200 for the MDF
$100 for Miscellaneous

If you add up the costs in the BOM it will come to about $1360. This wouldn't include things like brushes, printing, etc... (Miscellaneous) Most people spend between $1000-$1500 to build the MDF machine. People have also built it for less. My breakdown includes things like black oxide finish nuts and bolts that you could easily source at Home Depot (plain zinc finish) for a lot cheaper!
Alterations are easy to do since you get all of the CAD files as well as the documentation. This makes it easy to make your own modifications! Various formats are included and can be read by most all modern CAD systems.
Absolutely! I have looked into the costs locally and they are about $400 to have the parts CNC cut. This includes the material! I include a CNC file that is already nested and ready to be sent off for quote! Or you can do like I did and hand build V1.0 and then use the V1.0 machine to re cut the parts for V2.0!
I am not interested in going into production and then shipping heavy MDF. Local CNC shops are going to be much less expensive than I would be to do this work even before the shipping costs. The MDF is already local to you and Home Depot and Lowes is keeping it warm for you!
I was able to do everything I wanted to cut on it when I built it. I was not interested in cutting aluminum, for example. It was accurate enough for plywood componets to slip together and did a great job of shaping foam molds. I cut Corian, Plywood, MDF, Hardwoods, Butcher Block. It was a great experience and for a relatively small investment, I was finally able to CNC things in my own space!
