  1. The UC-100 worked.

    Posted by on Mar 8th 2021

    I originally bought one off of Amazon, it did not work, turns out it was a counterfeit it. No drivers. So I began to research the UC-100 through Google and found CNCbasis.com. They have a YouTube channel and I watched a few of their videos and did some more research and found that Amazon, eBay, etc were selling a counterfeit version of the UC-100. I ended up buying another UC-100 from CNCbasis.com they had a link to the drivers for download. I downloaded and installed the drivers, connected my milling machine to my laptop set pin locations for XYZ Axis in Mach3 and was up and running.

    Great company to deal with
    Purchase a UC 100 and I was having grounding issues with my machine. Spoke to the owner of the company and he was actually willing to spend some time on the phone to try to figure things out highly recommended.
    And the UC 100 works perfectly..

    Johnny was very helpful and replied quickly. Was nice to be able to get the gender change and cable along with UC100 all in one package. The 2 LRD lights are a nice way to see whether it was working.

  4. What I needed

    Posted by on Nov 30th 2019

    I was having problems with my parallel pretty on my computer talking to my CNC. This product was recommended. I received it and immediately worked on my machine. I would have given 5 stars but less than 4 hours later, it stopped working. After doing some troubleshooting, I found out the USB/ micro cord that was provided went bad. I'm not sure if it's just a cheap cord or just unlucky to get a bad one. Anyway, i replaced it with a new cord and it has been working great ever since.

    Thanks CNCBasis for the UC100 I purchased now having a way of connecting my Dave Gatton Cnc build to my New but Old Dell laptop is absolutely a blessing. My old desktop PC with parallel port failed I was in a state until I saw Dave show off his UC100 controller. Did not have one issue with software install worked from the start Thank You again and happy CNCing
