Thankyou for that info. So is there any other reason that one shouldn't use a single power supply to power both the ether1616 and acorn (and only those two boards) together?

Re: Acorn Power Supply Question

As stated above, you should use a separate power supply for items that can induce noise, such as contactors, relays, and solenoid valves. But will the ether1616 generate noise for the acorn MPU? It does have relays, but so does the 8 relay board that comes with the acorn. I very specifically stated...

Re: Acorn Power Supply Question

Can you use a 70w plus power supply, say a Meanwell NDR-75-24, to power both the acorn and the ether1616 together?. Another PS to power all other 24 volt coils. It would save space in the cabinet. Thank you

Re: Acorn for DIY CNC cam grinder on CNC lathe

Setting up the spindle as C-axis with the grinder on X should work. If the center of the grinding spindle is on the same height with the C-axis change in diameter of the grinding wheel will not change the cam profiles, only the size which could be easy dialed in after dressing the wheel. Uwe A cam ...

Re: Acorn for DIY CNC cam grinder on CNC lathe

Regular CNC controllers cannot actually generate accurate cam profiles. As the wheel is dressed, the wheel gets smaller. This changes the geometry of the lift and fall portion of the cam lobe as its not on center of the wheel as its grinding in those areas. Commercial cam grinders that I work on, bo...
