Gingerbread - A New Material Category?!?

[jeffeb3]

@leo69 used to be a regular here. I remember a good thread where we talked through the firmware and CAM, but I can’t find it.

I wonder what power I’d have to run the laser to engrave gingerbread.

[jeffeb3]

The real question is, would it smell amazing or terrible?

[kvcummins (K Cummins)]

Depends on where Hansel and Gretel are…

I know burning oak makes me think of the bbq thread.

Anybody tried designing a rotary add on?

I have some spare steppers around, and I was thinking of trying to come up with a rotary style attachment (like you see for Chinese laser cutters). Just wondering if anybody else has started on that at all (no need to duplicate it if it exists elsewhere already).

Laser etch wood dowel ideas needed

I had a friend stop over today and really liked the mpcnc and the laser. He has a small side business that he would like his company name etched on a wood dowel. Anyone have any ideas on how to add a new stepper to rotate the dowel after each line etched? Curt

YES! That brings me back. Was that three years ago? Specifically, I was remembering this post:

If you imagine the outermost layer, unrolled, and laid flat… If you wanted that to be square, where 1mm in your drawing in x ended up being the same distance as 1mm of your drawing in y ended up being, then: You’d have to compute your steps/mm based on the outside radius of the object spinning. It’s a simple calculation, pi * diameter gives you one entire rotation, so: steps per rotation / (pi * diameter) If you want the deeper cuts to be aligned underneath the top layer*, then you don’t …

Also, in that thread was the vicious1 logo. I didn’t make a crown until yesterday, but I do remember carving that logo in some foam.

One thing Discourse has done is make it so much easier to search and find things. It is just so much quicker.

I’ve given this some thought. Next year’s gingerbread house needs to be a CNC’ed pirate ship. You can probably find some pretty good reference drawings for a ship already, and it would let you create some crazy fun details. Pirates are christmas themed, right?

Bet you could find a good model of the Nakatomi building…

hint: Look for “Fox Plaza” as well…

Was thinking a rotating Carousel…but pirates have potential

[niget2002 (David Walling)]

Need to think outside the box… A rotating carousel of pirate ships.

Rotating Pirate Ship of Carousels?

Check out Thingiverse for a simple rotary axis. This could replace one axis (I use Y on my K40 laser) but would need to reconfigure the axis steps per mm. Easy to do with Grbl, not sure how tough with the MPCNC boards and firmware.

I’m too new to post links, but look for item 3174149.

[jeffeb3]

Easy to do with Marlin M92, IIRC.

The mind boggles…

That’s a good one for a laser. I’ve thought of something like this for my Glowforge, but you can’t easily hack the hardware and software to do something like this.
