Build the machine is very easy but time consuming using the supplied YouTube videos. There were three problems I found during the build. The first is the video needs to be updated to include the Blackbox. The video shows a control board I couldn't even find on the website. There is a video for the Blackbox that does cover the build process and how to connect and install the software. Really detailed information on both videos, just remember the pause button is your friend. The second problem that is not really aa problem just need to update the video to show the Dewalt router. This machine will hold different routers, you just need to make sure they will fit in a 2.75 inch or 69 mm hole when the base is removed. The third problem was with the stop buttons. They do not line up as needed when using the supplied black washers/spacers. The one one the Z axis will actually get damaged if the Dewalt router is moved up to the higher points of use. I used my 3D printer to make some that were only 2mm thick which allowed them to contact the plates as needed. I suggest that Openbuilds make adjustments to these to fit as required to allow for proper operation in the future. This was my first ever CNC machine and I had no problem building or running it with the supplied patterns and operating programs. I ordered the Cut2d with it and found it to be easy to use with supplied training videos from Vectric. I would recommend this machine to anyone wanting to have a good quality CNC machine for their personal shop. It will easily perform any work within its design range. I plan to purchase the largest machine Openbuilds has to offer in the near future. Until then I will spend my spare time getting use to the Vectric design program and running my designs on the C-Beam machine.
First, the kit is great, this was my first from openbuilds, and I'll be buying from them again. The machine is pretty great out of the box, I did some test cuts on aluminum and it seemed to handle things well. I do plan to upgrade the Z height, switch the X axis to linear rails, and probably reinforce the build plate with additional extrustions and linear rails. and great thing about this machine is it is rigid enough to create its own upgrades out of aluminum plate!
Picked this up forever ago but got around to building it this past winter (got side tracked by a new born). The learning curve was low and this thing has plenty of power. Been cutting aluminum and acrylic with this thing and couldn't be happier with the performance. Lots to learn since I have no history with CNC, but the results have been excellent and I think it's the perfect plate maker.
Beast of a machine!
