    I had two acorn boards show up in the last couple of days. Dragged the lathe out, dusted it off, cleaned it up and fired up Mach one last time. Everything checked out fine. Ran pretty quiet, now I am second guessing if I should build a second controller....Screw it I will just use this controller.

    Pulled the original CNC4PC boards from the controller. Left the power controls and 5056 stepper drivers. Moved the drivers over on the mounting plate to give a little more room for the Acorn board in the controller. Got the Acorn board mounted on standoffs. Mounted and wired the Centroid 24V PS. After about 4 hours of messing around I had Z and X axis moving around. I had to reverse the X motor direction. I did that by reversing both pairs of stepper motor wires at the driver. I am trying to keep the Centroid settings close to default if possible. Another couple of hours and I had Z and X calibrated under .001' and backlash set. I used .001" for both Z and X. Its amazingly close at the moment. Now on to the VFD wiring. Upgrading from an existing Mach setup is sooooooo much easier than doing this controller from scratch. Actually its pretty fun because it moves along so quickly. So much less troubleshooting. Also Centroid provides all kinds of schmatics to help with various configurations. Its helping me a lot to understand proper implementation of the various safety and interlock systems we often over look on home CNC builds. I built a dedicated WIN10 machine from a 5 year old game machine I had laying around. Plenty of performance. Did a fresh install of WIN10 and configured the OS per centroids recommendations. So far the solid seems much more polished than Mach although I am going to do my best to not talk negatively about Mach. I got us where we are today and made a huge impact on the CNC world. I really appreciate the clean and uncluttered look of the Centroid software interface so far. It really has a professional / commercial feel to it.

    Here is the new layout with the Acorn Board. I will clean up the wiring after I get a few more things completed like the VFD and spindle encoder. I plan to add a proper ESTOP circuit per Centtoid specs, home flags, limit switches, a 4th wire for the 240V circuit. Flood coolant relay. Led enclosure lighting.
