I have the Low roller version in order to get the biggest z distance on my smaller laser but haven’t used it very much yet. I did a few test engraves and it was very easy to set up and level some odd sized wine glasses. Not sure why anyone would think it is complicated but I’m not offended, lol. The knobs make the adjustments for leveling and setting the glass distance very simple and precise.
Mine was comparable in price to the one that was specced by Thunder Laser when I bought my laser and I think they are now the recommended rotary being sold with their lasers in the US. I have the original 7 pin rotary from Thunder Laser for sale at a good price if anyone is interested as I’m keeping this one.
I mainly use it to do tumblers, cups, and heavy glass beer mugs. The rotary that came with my laser had some play it it that really effected the glass mugs. The weight of the handle would cause over rotation. Also, I no longer have to mess with the rotary settings when switching to different sizes. The RotoBoss is geared at 1:1 so all I do is set my circle pulse to what my laser is set at and the wheel diameter to 2.25” which is the actual size and forget it.
I just connected my Rotoboss. It doesn’t work when “enable rotary” is on. When I turn “enable rotary” off in Lightburn, I attempted to engrave a 1" by 1" square. It engrave it 1" tall but 4.25" wide. Can’t figure it out.
