yup, depending on the height (I can always put the laser gantry on 'stilts') I still plan to do rolling pins. I would also like a strong air assist when doing the rolling pins as I think this will help engrave deeper.
the idler rollers are in between the supports holding the rod. I plan to make these of different heights for different sized objects.
Strange, the video works ok on my phone but not on my pc... no biggie, just a video of poor lasering on a bit of bamboo
