Phase 1 of my Sherline rotary table to Novakon mill adaptation is complete. I had to change out the 5 pin circular connector on the back of the mill to a 7 pin connector. A 6 pin would have been ideal but I found a 7 pin bulk head circular connector at my local surplus store that was nearly a direct fit. I split all 6 wires on the rotary table motor into the connector so I can use 4 of the wires on the Novakon in bipolar mode and I then made an adapter plug that has a matching circular connector on one side and 5 pin din connector on the other and the commons are tied back together inside the plug so I can still use my stand alone pendant controller which runs unipolar. I plugged it into the Sherline controller and it works still, but then I had one of those oh crap moments when I realized I had forgotten to put the body of the din connector onto the cable before I soldered everything together, oh well I needed more soldering practice. Tomorrow I'm buying an 18K resistor so I can change the current setting on the gecko for the 4th axis on my Novakon controller from 3 amp to 2 amp and then I can hook the rotary table up and try it on the mill. |
