Still my go-to for CNC parts

I've bought from OpenBuilds several times, and they're consistently reliable. This time I got a BlackBox Motion Control System and a few Anti-Backlash Nut Blocks. The BlackBox was easy to integrate with my existing setup, just like my previous Sphinx CNC kit was. Shipping was pretty standard, about 4-5 days, which is what I usually experience. Their parts always fit perfectly; never had compatibility issues with their V-Slot stuff. It's why I keep coming back instead of trying other places.

Got my NEMA 17s fast

Ordered some NEMA 17 Stepper Motors for a small project. They arrived pretty quick, like within 4 days. Everything was packed well. Really happy with the motors, they're working great in my setup.

Good parts, slow shipping to Denver

I ordered a C-Beam Linear Rail and some Solid V Wheel Kits. The quality was good, exactly what I expected from OpenBuilds. My only real gripe was the shipping time; it took 5 days to reach Denver, which felt a bit long. Customer service was helpful when I asked about tracking, so that was a plus. Overall, good value for the price, but they could speed up delivery.

Hey, thinking about grabbing one of their CNC kits, specifically the WorkBee. How long does shipping usually take to, say, California? Trying to plan out a project.

M Mia P. 4 months ago
I just ordered some V-slot rails and wheels to San Diego last month, got here in about 5 business days. Pretty quick for standard shipping I thought.

Yeah, I'm in NorCal and my BlackBox controller showed up in under a week. They ship from Ohio I think, so coast to coast is usually decent. You'll probably get your WorkBee kit in about a week or so, give or take a day.

Does anyone know if OpenBuilds ever do sales on their kits, like the Lead CNC? Or is it mostly just individual parts that get discounted? Trying to save a few bucks if I can.

G Greg E. 4 months ago
They totally do! I got my Sphinx kit during their Black Friday sale last year, saved a good chunk. Keep an eye out for holiday sales, Christmas too.

They have bundle savings sometimes too, not always a huge percentage but it adds up for bigger kits. Also, if you sign up for their newsletter, they occasionally send out promo codes. Can't stack them though, learned that the hard way lol.
