Hello, I am having issues with engraving on tumblers. Every attempt at it leads to a distortion of the image. I am using an XTool D1 5W diode laser with the older Rotary tool (using the one with two roller pins). Every try leads to the image being squished and I can’t figure out how to fix it. Trying to counteract the distortion by altering the image in the opposite manner doesn’t work either. Attached are images of what I am talking about.
One thing I used to do with my CO2 laser when using the rotary tool was to make a 10X10 or 20X20 square. I would apply some tape, so as not to waste the tumbler, lower the power, and mark the tape. I would then measure the size of the square. Then you can go into the rotary settings and adjust the mm/rotation
Is the width correct?
The rotary setup is pretty straight forward. You need to figure out how many steps it takes to rotate the motor shaft one complete turn and back when ‘test’ button in the Rotary GUI.
This will setup the machine to properly step the motor.
With a Chuck rotary, it’s setup… although you will have to enter the objects diameter.
With a wheel (roller) rotary, you have to multiply the steps with the gear (belt) ratio for the final outcome. Once it’s setup, it should work with any.
Before I get too far ahead, I remember the mm/rotation usually being 80… not 360… but I don’t really follow all these machines.
It seems to me this would ‘squish’ it in the vertical direction in the photo or what I’m assuming is the Y axes (maybe A on your machine)…
