I have an atomstack A20 with an R3 rotary. The R3 rotary plugs in place of the Y axis.
I have an SVG that cuts perfectly fine on a flat plane, but when I swap the Y axis for the rotary (using the same gcode, not using any rotary feature in lightburn) it gets garbled in the X axis. I have no clue what is going on. Any suggestions would be very welcome.
Looks to me like the rotary is just slipping.
A few contributing factors:
- Looks like this is being done in line mode. That will require your rotary to turn back and forth which will be hard to do without slip
- Seems like the cylinder is not retaining position along the long axis when rotating back and forth
- Your speed/acceleration settings may be too high for your equipment with this operation
I’d suggest moving to a horizontal scanning/fill operation making sure that the rotary only ever moves in one direction.
Here are some tips running a rotary: Rotary roller - Diode Laser Wiki (most have been mentioned by PY already)
You might need to add weight to the object to make it less slipping.
Thanks - I’m trying your suggestions. One thing I would like to do is keep paint on the airplane. Is it possible to do a horizontal scan over the airplane but leave the fuselage and wing panels uncut? I don’t know how to leave an interior island is what I’m getting at. I am working with an SVG. Thank you in advance.
Yes. Create a shape that matches where you don’t want filled. Overlapping portions of shapes become negated. You could potentially do this easily by doing an Inset using the Offset Shapes tool.
