I have a Novakon NM-145 stepper (with the newer model spindle motor), and wish to upgrade away from Mach3 which is unreliable.

I have asked for a DIY quote from Centroid, but also wish to know if Upnorth and others may have modified their Novakon systems to Acorn/Centroid vs moving over to Mach4 without hardware changes.

You will have to do some hardware changes. The good news is that the Acorn kit includes almost everything you will need. I had a Torus Pro not the NM-145 so it may be different for you. In my case I removed the Novakon break out board and the Ethernet smooth stepper. These are replaced by the parts that come with the acorn kit. You will also need to install the relay board and power supply (also in the kit) so you may need to shuffle some components around.

The only part I had to buy was a power relay that had a 24 volt coil in order to replace one that had a 12 volt coil. A good quality one was about $15 made by Omron. Took less than ten seconds to swap it out.
