CNC Controller Build

I built many of the circuits at the component level so I can get the exact specifications and quality I wanted. I was quite happy with the build, I only had to tune in the motor drivers, and it has worked perfect. "Love it when a plane comes together" J.H.S.

Fun fact :{ - If all the wires for this build were strung end to end, it would extent for 1/3rd of a mile.

CNC - Power Supply

Hard Features
  • Designed for 20 amp 38 Volt operational - 40 Amp Max
  • Incoming AC filtering.
  • Triac soft start circuit to keep heavy startup load and from wearing out the lacquer on the transformer windings and to minimize rush current.
  • Delayed power relay to bypass the Triac to minimizes voltage drop.
  • T,C,L,C filtering using extra transformer as a current dampening coil.
  • Microcontroller to control soft features monitoring and status display.

Soft Features
  • Soft-start up programing features, power up component failure checks.
  • High and low voltage actions and alarms,
  • Over current draw action and alarm
  • Temperature monitoring
  • AC line dip/glitch protection cutout and alarm.
  • Status display panel, voltage, current...

Anyone who has gone to Radio Shack
is familiar with these. I have known the local owners since the 80s, and when RS whent out of business, I could not foresee my self with out a ready supply of parts , Sooooo... >>>>

Lead Sulfuric Acid Battery Conversion
to Lead Sodium Sulfide Salt

I converted a medium size car battery from sulfuric acid into a sodium sulfate salt based battery. I ended up using this in my 1500va UPS, and its working fine.

Test results;

  • 1st run - blue, the plates need to start incorporating the new solution, so not so good.

  • 2nd run - green,  plates are getting more acclimated to working with the salt.

  • 3rd run settling in and base line for run time calculations,

​

One thing to note is that you can run the batteries down to 0V with out damaging the plates like when using sulfuric acid.
