I am mounting linear encoders on my CNC converted milling machine. Will it help the precision or backlash? I don’t know, let’s find out. Part 1 is the mounting of linear encoder on the X axis. source
Adding On/Off/eStop spindle control to the Vevor 3020T-DJ CNC Router/Engraver. This “hack” works with JP-3163B and JP-1482. The below machines might have different boards than referenced in this video, but this is the CNC I have… 4-Axis 3020T CNC – Parallel Port Version (This is the version I have) http://amzn.to/2s9lRL9 4-Axis 3020T CNC – USB
Stepper motors have high torque to hold position but AC servo motors have much faster travel speed as well as high torque. Also with feedback loop servo motors keep accurate position within 5thou. In this example, both machines are running at full speed. Servo CNC on the right travels 2500 inches per minute with 50
The CNC has a half sheet of plywood cut capacity with a maximum thickness allowance of 6″. The entire unit cost under $900 to make.
