In an attempt to decrease as much weight on my mill's headstock I rewired the control box normally found on the mill to the back. It was A LOT of work but not only is it lighter, I can see my work MUCH better. If you plan to do only one modification (other than the safety
I have also taken the 2nd part of the pulley off to decrease more weight and have turned it smaller. Adding to this, I made a new larger motor pulley to increase my rpm. Right now with the CNC Setup, I have a spindle on/off light and a main on/off light.
Please see below how to add your own main light.
Lighting the Head and Making it Easier to See Your Work
- I personally suggest this modification -
If you're not comfortable with wires don't try this, don't ruin your perfectly working mill! I rewired the speed control, spindle on/off LED and the main on/off 110v light to the plate that the control box is originally mounted from.
Here you can see that the entire control box has been removed and mounted to the rear of the machine. The second smaller box is the power for the 12v halogen. The head is much lighter and the work is MUCH easier to see, a huge advantage!
To help out my Z-axis stepper, I added simple springs to aid in pulling up the weight of the headstock. It helps out quite a bit. In this picture you can also see a bright yellow LED (where the control box normally mounts) which tells me the spindle is on via CNC.
Another view of the wiring. Again, I think this might be the BEST modification to do. You can't imagine how much better you can see your work! Again, make sure you comfy with soldering and playing with wires.
Red Wire Motor + Main wire, must be connected
Black Wire Motor - Main wire, must be connected
Green Wire Ground to motor's backplate screw Main wire, highly suggest to be connected
Orange Wire To heat shutoff unit in motor Extra, does not need to be connected to work, but connect to be on the safe side
White Wire To heat shutoff unit in motor Extra, does not need to be connected to work, but connect to be on the safe side
