Centroid Community CNC Support Forum

Hi Mike, I took a look at the FreeCad website. I was interested in what CAM functions were included. I found references to 3D printing, LinuxCNC, and grbl, and how you might go about creating your own post processor, but no other posts built in. Am I missing something? CAM is one of the great values...

I had a problem with closed loop steppers on a bench set up creeping like that. I tried various remedies with no success. The closed loop stepper drives were rated at 200,000 hz. Out of curiosity/desperation I changed the output on the Acorn to 100,000. Creeping stopped. YMMV but I thought I would p...

A couple of fine points: 4-axis CAM is not supported either. 3-axis is still supported. They advertise the 1 year license as $297 / $25 per month, but there is no option to pay it off monthly (at least not that I could find) There are other restrictions with the new free version, such as file types ...

You wouldn't use a VFD to control a simple DC motor. You could buy a KBIC controller and KBIC-240 isolator board on eBay. Then use the 0-10 volt output on the Acorn. Marty has a video showing the setup on the Acorn User's Forum

If you finally determine that you've trashed your Acorn, somewhere on Centroid's website, there is an offer for a discounted board for folks in your same situation. It's kind of buried, so you'll have to do some searching.
Good luck

Gather all your electronics together, Acorn, drives, PSU's, etc. Lay them out on a board and arrange them until you're happy. Then look for a control box that is larger than that, as you will want to add or change components throughout the life of your machine. Too many people start out with a box t...
