So my brother who is involved with a few minor baseball leagues has asked if I could carve the names and numbers of players into baseball bats. Is this possible or would I have to set up a lathe type axis on the mpcnc like I’ve seen before?July 8, 2019 at 5:31 am #105482
I’ve not tried this, but it might work. If you can model the bat, maybe just with a simple cylinder in fusion 360 or something, you might be able to do some limited carving using that. I don’t know if you can use Estlcam, but you could use VCarve to project text onto a 3D model. Even so, you will still have a very narrow axial region to carve on. The rotational axis would be much better, but it’s more complex.July 8, 2019 at 9:34 am #105543
There are a couple rotational axis for the MPCNC on thingiverse, it does take a bit of work though.July 8, 2019 at 3:30 pm #105592
It is easiest to carve on to a plain cylinder. Estlcam + Arduino can map the curve as Christian demonstrates in one of his videos. I don’t think the ‘software only’ version used with a Rambo or Mega has that option available.
Otherwise you can build a simple rotary axis using a stepper, coupler, rod axis, and a scroll chuck or collet to hold one end the bat with a roller for the other end. This is a little more complicated proposition but works. You have to wire the stepper to X or Y and disconnect the ‘regular’ stepper for that axis (and make sure it doesn’t move) then proceed from there. Easy with a laser and probably keeps the bats in Regulation (I don’t know much about such things). Harder but doable with a router if you don’t get carried away with depth.
You can try to model the curve in software and create a 2.5D file to run with Estlcam but that depends on the software options you already have.July 8, 2019 at 3:52 pm #105593
Christian demo’d “CNC surface scanning/auto leveling” to engrave his mouse a while back. That maybe all you need to do a bat, avoiding the use of a rotary fixture. Of course… I don’t know if the current version of Estlcam supports that, it was an old video (version 8 of Estlcam I think).
ps… I’m NOT stalking you, Jeff… I guess we just happen to be on during the same times during the day

The Current Estlcam version 11.113 supports the mapping function for sure.July 9, 2019 at 5:01 am #105660
