I have to respectfully disagree with you. I have lost track over how many Acorn builds I have done, how many Acorn related videos I have posted. I have used and tested many stepper drives and have not experienced what you have experienced.

I spend hours of my own time helping others on the Centroid CNC User forums: https://centroidcncforum.com/viewforum.php?f=60 and no, I am not an employee of Centroid. I am an avid hobbyist interested in CNC Motion Control. I have helped beta test the hardware and software since Acorn's inception. I do it because I believe in it.
Centroid has been around for over 30 years and specializes in CNC Machine motion control. They came up with an integrated solution, they write the software for the hardware. They are contantly improving the hardware and software based on customer feedback.
All you have to have is basic electronic and electrical skills OR find a friend that does and follow good control wiring practice. Its a very well supported product.
I am truly sorry it has not worked out for you. I assume you have been on the forum and asked your questions? What is your user id on the forum? Be happy to go back and look.
Centroid controls may not be for everyone, there is certainly a wide range of control choices out there. Perhaps another would suit you better.
As for features here is the list, showing free, Pro and Digitizing Bundles. Given the machine and specific user needs, many are fine with the FREE version, most spend the money to upgrade to the Pro version.
Every option is in plain sight for the user to decide which way to go:

Good luck on your projects. Please let us know how we can be of further help. Lots of experienced users on the forum helping each other out, not to mention frequent visits from Centroid Tech Support staff and even a long time Dealer/veteran installer of Centroid controls trying to help users. The forums is the place to go for help.
Kidnest regards,
Marty
