    Quality kit for a good machine

    Posted by Stephen on Jun 8th 2020

    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!

    Great starter machine

    Posted by Andrew Wright on Jun 18th 2019

    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.
