Lr3 4th axis machine

Hi all it’s been a while

My Lr3 has been sitting around for a while then it came to me turn it into a dedicated rotary machine

My thoughts were to keep the gantry at 1.2mtr and shorten up the bed to about 4 or 500mm

I run one of the first jackpots

Any thoughts about my project

Should be easy enough. I would mount the rotary axis so the axis is at or below the current table height. Not sure hat software you will be using for CAM, I have not had any project ideas come to mind to want to try it myself yet.

Seems a pretty common request. I’d use it for a bunch of stuff, even simple stuff like making custom size/material dowels. Turn yourself a big wooden sphere…

All doable with 3 axis but a 4th axis is a much more elegant job and avoids needing long tooling for larger pieces.

Hi Ryan so my jackpot V1 will run the 4th axis

Yes, you will need to edit your config but you have a spare driver, just get or make one with an appropriate sized driver and you won’t need anything else.

Hi Ryan ordered new drives. what changers to the code are needed

What did you order?

The Config.yaml file has a “C” driver section in it. I belive that section is where all your changes are needed. Just uncomment it and tune it to your 4th axis.

What software are you planning to use? I use Lightburn with a rotary, but it is for a laser not a router.

Thanks for the help

Hi I use vectric aspire but I’m thinking I may need to use fusion for the more complex designs with fusion I can change the centre axis and I think I can also do the tool paths
