    •   Can I buy one Pro Acorn CNC12 license and use it on several Acorn CNC control boards?

    •   No, the Centroid Acorn Pro and Ultimate licenses are tied to the Acorn board serial number. When purchasing a Pro or Ultimate license, the Acorn serial number is required and then a Pro or Ultimate license is created that matches the Acorn board serial. When the CNC12 software starts, it checks the Pro or Ultimate license against the Acorn board that is connected to the CNCPC for a match. If it matches, then that particular level (Pro or Ultimate) of CNC12 software is made active. If it doesn't match, then the CNC12 software runs at the "Free" level. (So Acorn CNC12 will run without any license installed)

    •   If I buy an Acorn Mill Pro CNC12 license and then decide to upgrade to the Ultimate license how much does that cost?

    •   $299

    •   Can I buy an Acorn Mill Pro and Acorn Lathe Pro and Acorn Ultimate for use on the same Acorn Board?

    •   Yes.

    •   Can I ask Centroid to move a Pro or Ultimate software License from one Acorn board to another?

    •   If Centroid issues an RMA for an Acorn board to be returned, any License associated with that board can be transferred to another Acorn board.

    •   Do I have to state at time of purchase what machine I plan on using the Acorn with?

    •   No. Both the Mill and Lathe Free version of Acorn CNC12 control software is available for download so you can configure the Acorn controller for a wide variety of machine tools. The hardware doesn't care what kind of machine it connected to.

    •   If I bought an Acorn Mill Pro License, can I use it with the Acorn Lathe Software?

    •    No. The Acorn Pro License is Mill and Lathe specific. There is a Pro License for Mill and there is a Pro license for Lathe.

    •   If I destroyed the BBG (Beagle Bone Green) that came with my Acorn board can I supply my own?

    •   Yes, but the License file(s) that were issued for that Acorn will not work with the new BBG. Centroid offers License transfer service for $29 which requires you to email us a report.zip file to diysales@centroidcnc.com. Information on how to generate a report.zip file is here.

    •   How big of a G-code program can I run with the Free version of CNC12 software?

    •   50Kb.
      To give you an idea of what can be done with the Free version of the Acorn CNC12 software: on our website is a part program for a SEM DC servo motor cover plate, below on the left is the plate being installed and on the right is the tool path that was used to make the cover plate. This G code program to make this part is 5Kb in size. This is pretty typical of a home hobby shop type part. The G code file generated by a cad cam system or in this case Centroid's Intercon conversational programming software (with comments!) to make this part the G-code program is only 5kb in size. The Centroid FREE version of CNC12 has a file size limitation of 50KB so you could run a G code program 10 times this size with the Free version of CNC12. As you can see, you can do a lot even with the Free version of the Acorn CNC12 software.

      The 5kb Gcode program used to cut this SEM servo motor cover plate is available here (click to view, right click link and Save as to download).

      Note: The Centroid PRO version of CNC12 has no file size limitation so you could run a file as large as the hard drive on the CNCPC and the Ultimate License also has no file size limitation. (only limited by the size of the CNCPC hard drive space)

    •   How long does it take to ship the Acorn CNC control kit?

    •   Typically the Acorn CNC control kits are in stock ready to ship and ship within one or two business day from Howard, PA via UPS GND. You will receive an email with tracking number when your kit ships.

    •   How do I contact Technical Support?

    •   Free Acorn Technical Support is available 24/7 on the Acorn CNC community support forum. Here is how to sign up for the Free Support Forum. Centroid Direct Technical Support is available for $120/hr. one hour min. purchase support here and email support@centroidcnc.com with a current Report.zip file.

    •   Do I need to purchase a PC from Centroid or can I build my own?

    •   Ready to run Centroid CNCPC's are avalible for sale from Centroid, alternatively you can supply your own CNCPC as long as it meets the Centroid Minimum PC performance specifications found here.

    •   What is the Acorn Return, Warranty and Repair policies?

    •   Please see this page for complete details.

    •   Is there a return restocking fee?

    •   Yes. There is a 15% restocking fee on all returned parts and products.

Centroid Acorn CNC controller reviews

Looking to order boards and other parts from you this week. I've got to admit - SO NICE having a board and software made by the same company. No plug ins from other places and the headaches. Literally followed the video and the motors were turning by the time it was done.
- Revy
After dealing with Mach 3 and LinuxCNC for years, I must say Centroid is Light years ahead. Up and running bench test in a matter of minutes instead of days as with those other products. There is much to learn about Centroid but I am confident it is a very solid product. I can't find the words to properly describe the difference.
 - Makeron
My son came to me and said that the students in his high school woodworking class could not finish their projects due to their CNC router is broken. Well I couldn't let this be and in less than an hour, I installed a acorn on their router and all the students were able to finish their projects. I donated the board to the school so they could continue to use the router and many students will be able to familiarize themselves and use the Centroid control. Thank you Centroid for making such an awesome easy to use and install product. Keep up the good work!

I have to say a big THANK YOU to Centroid for providing the best value in DIY CNC on the market today. I just completed the upgrade of my CNC router table to Acorn and couldn't be happier! Followed the schematics for the GeckoDrive 203V (only thing I kept from my old controller) and everything just worked without any issues. Watched a lot of video's that provided almost everything I needed to get my machine working. I saved so much money over upgrading to Mach4, Smooth Stepper and PMDX boards that I had planned for my initial upgrade that I bought a touch screen monitor, wireless pendant and upgraded to Mill Pro. The pendant is just amazing to use. I feel like I have a professions system now! Not sure how you can sell the entire acorn kit for the price you do, but thank you for providing this to the DIY community.

Yesterday, I received a model 4 Acorn and an extra relay board for my model 3 Acorn that I bought almost a year ago. Opening that package reminded me of the care and concern that Centroid has for its customers. The power supply was pre-wired for the Acorn. The instruction sheet is comprehensive. The backside of the instruction sheet that shows a connection schematic that should make initial connections fool-proof. I just noticed that even those schematics are printed in color. (My eyes have serious problems.) The new schematics that Keith notified us of have fixed all of the connection problems that I've experienced with ClearPath servos, Gecko G203 drives, and Leadshine (clone) drives. Those problems were not Centroid's fault. (The older schematics followed wiring diagrams from other manufacturers that were somewhat lacking. I've read Teknic's manual carefully about the fault signal. The older schematics followed the Teknic manual. Keith and Gary solved that problem months ago, but because I had a work-around, I didn't carefully read the revised schematic that Centroid published months ago.) I was able to work around those problems; but the new schematics make those work-arounds obsolete. It amazes me that Centroid is willing to spend money on so many do-it-yourself motors, drivers, spindles, VFDs and other non-Centroid products, test those products, draw up schematics to use those products and still sell the Acorn for $329 with the amazing Centroid software.

Next, the forum along with YouTube videos are great. Keith, Marty, Gary and Franco not only show how to use the Acorn, but teach general principles about CNC machining. Late last night when I couldn't sleep, I watched a video where Keith showed how to use a vertical mill. The video contained everything that anyone would need to see how to use Centroid products to make their equipment work. Clicking on "Acorn User Videos" from the Acorn page shows a list of videos that show how to use the Acorn. Going on YouTube and searching "Marty CNC" brings up Marty's channel with a comprehensive list of how-to videos. Searching "Gary Campbell CNC" brings up Gary's channel and his expertly produced videos. (Gary and I go back decades to my Shopbot days when I constantly used his advice to solve my problems.) Clicking on "Centroid CNCKeith" brings up Keith's videos. His knowledge and easy-going style should make anyone comfortable in trying an Acorn. One of his videos was with "MecTechMike". Mike's mill and lathe conversions should impress everyone. He surely impressed me and gave me ideas that will take at least a year to try. There are many, many others who have taken the time to post videos showing how they use the Acorn and other Centroid products.

The forum is invaluable. Questions are answered expertly (in most cases). Since I tend to be disruptive in some of my posts (unintentionally - I like to think outside the box and try things that might seem to be controversial), I expected harsh feedback or even censoring, but I've been treated with respect and courtesy. More, importantly, by reading what others are doing, I get ideas that would take a life-time to implement.

Thanks Centroid and thanks to all of you in the Acorn community for your help.
