MPCNC onboard a ketch

Hi folks,

I’ve been lurking here since November, dreaming of an improved way to mill wood trim for the boat I live on. Having finished recoring the decks, replacing all hatches / portholes / windows, and adding new cockpit seating and helm, I’ve been refitting belowdecks cabin by cabin. Turning door/cabinet corners on the lathe, or using jigs on the shaper table has been a very slow (and sometimes dangerous) process!

A few years ago, I built an Ultimaker 3d printer from a kit, and used it extensively. So Allted’s approach with the MPCNC appealed to me immediately. Mid January, I used the excuse of seeing used 3d printed parts for sale on these forums. I rounded it out with some new steppers and belts from V1 in late January, and cut new stainless tubes (the boat environment rewards Stainless Steel!). Because the mill has to fit in my shop (a partially converted crew cabin crammed full of bench tools), I made the base roughly 3’x2’ so that the whole mill can rotate up when not in use. I used plywood for the waste table, since MDF doesn’t fare well onboard.

After doing wiring and belts yesterday, I did the first Sharpie crown test this morning. I’m pretty stoked, even with some gotchas to work through.

So, I’ll look for ideas on a scaling issue (evident in the second picture below) in a separate post, but wanted to shed my lurker status. Thanks for the original design, and the great can-do community here on v1!

If that is my gcode for the crown make sure all 3 jumpers are under the drivers. If that is your own gcode follow the other thread you started.

Ahh! good call, Ryan. (I bought the RAMPS board used, with drivers already installed, so hadn’t thought to pull them off to verify the jumpers.) I’ll have to wait to verify the fix since I don’t have fine enough wire onboard (or extra jumpers.)

And yes, that was with your gcode.

Thanks!

Your set up has caught my eye. I plan to do similar in making my set up portable and stow able. I plan to set mine up on plywood that will be bolted to a table when in use and then unbolt and either hang it on a wall up and out of the way when not in use. I don’t feel I have the floor space to commit for my machine. I am making mine 18" by 24" working space.

I was wondering how you were managing the electronic components when you store it away. Do you have neat disconnects or what?
