I bought a two trees 20w pro laser and also purchased the rotary tool. I can’t find any info on how to install the rotary tool. I am an artist that does a lot of work on bamboo and want to get this going. I tried installing it but, just doesn’t work. Any advice would be helpful. I tried YouTube but, the new laser doesn’t show up for how to install the rotary tool. Thanks in advance for any help.
Here’s the basics
Plug your rotary into the cable from the mother board to the Y axis motor
Check your settings in Laser Tools Rotary Setup
Make sure rotary is set to Chuck if thats what you have
Enter your setting in mm per rotation. Mine is 165 but yours may be different
Then do a test.
The rotary should move in one direction then the opposite direction
And it should end up where it started.
I use a sharpie to put a mark on the rotary top center to see where it started
It should end up in the same place as it started
Then enter the circumference of your mug.
Set your start from to “Current Position”
Then manually move the laser head to the start point and do a frame.
Adjust as necessary until you get the frame in the correct position
This is the process i use
Check out this video. Different machine but the basics are the same
@baricl1317 , thanks for the video! It does a superb job of explaining how to set up rotaries. I have the xTool RA2 and really needed this helper.
Here’s another video when you get the basics down
Yeah, I will save that one for next year when I am ready for it.
