Simple and cheap rotary axis
« on: May 27, 2017, 06:26:10 AM »
This one uses a $2 stepper and works just fine for raster though backlash on gears means issues with vector images, I will be using to etch some pens for my dad.

The clamp has 2 urposes, one to keep the pen square and also to close up the endplay in the cheap motor, seems to work just fine.

Here is another option I found that is more orientated towards larger items.

Nottingham, this may work for you on those wine glasses

I am thinking of making one too by using the same step motor of the engraver.  If I use the same motor and plug in the y-axis (unplug the originals two), I shouldn't need any adjustment or gear to manage it's rotation.  Am I right?  The step motor should turn exactly the same as the original y-axis motors.

Not necessarily. going length-wise vs rotational length could be different. What software are you using? I know T2Laser has an option for a rotary axis. You will need to set the diameter of the object.

Remember, every object is different based on its dimension. The stepper will need to turn a different amount of steps for a wine bottle vs a pen. T2 takes care of this in software.
