Customer Reviews
Consistent quality for my projects
This was my third order from OpenBuilds. I bought more NEMA 23 Stepper Motors and some Aluminum Spacers this time. Just like previous purchases, the quality was consistent and reliable. Always get what I expect, which is important when building machines. They're my go-to for CNC parts because of that consistency.
Good quality, fast delivery
I ordered some V-Slot Linear Rail and a Solid V Wheel Kit. Everything arrived quickly, took only 3 days to reach me in California. Parts were exactly as described and worked great for my project. No complaints, will buy again.
Detailed feedback on my C-Beam Machine kit purchase
I purchased the C-Beam Machine kit, along with a Makita Router and a CNC Bit Set. The ordering process on their website was smooth and intuitive. Shipping took about 5 business days to get to my address in Colorado, which was reasonable for the size of the package. All components were well-packed and arrived without any damage. Assembly instructions were clear, although I did refer to some community videos for extra tips on the wiring. The quality of the V-Slot and C-Beam extrusions is very good, and the Solid V Wheel Kits roll smoothly. I did contact customer support about a question regarding the OpenBuilds CONTROL Software setup, and they responded within a day with helpful advice. The machine is now up and running, performing as expected. The bits are also decent quality for starting out. It's a solid kit for hobbyists looking to get into CNC without breaking the bank. Just be prepared to spend some time on assembly, but it's part of the fun.
Great value on the kit
I was looking for a good deal on a CNC machine and found the WorkBee CNC kit here. It felt like a solid investment compared to other sites. Got it during a holiday sale, which made the price even better. Shipping was free because of the order size too. Really happy with the overall value for what I paid.
Love my new Acro Laser System!
I just received my Acro Laser System and it's fantastic! Setup was pretty straightforward, and I had it running in no time. The quality of the parts is top-notch, and it works perfectly for etching. I'm already planning my next project. This store has awesome products, I'll definitely be shopping here again for more components and telling my maker friends about it!
Mostly good, one small issue
I ordered a BlackBox Motion Control System and a Mean Well Power Supply. The main items were excellent and seem very robust. Delivery was pretty fast, arrived within a week. My only minor issue was one of the smaller Tee Nuts was a bit bent, but it was easily fixed and didn't hold up my build. Overall, a good experience and good value, just a tiny quality control slip on one small piece.

Share tips, ask questions & help fellow shoppers save more
Hey, thinking about grabbing a WorkBee kit. How long does shipping usually take to, say, Seattle?
Are those router mounts compatible with a regular Makita RT0701C? Or do I need a specific model?
