mounting raspberry Pi - CNC combo

Post by jrdarrah » Tue Jul 16, 2019 12:37 am

I need some ideas on mounting the Pi with the cnc board attached with the supplied standoffs. With the raspberry Pi holes occupied by the screws to the standoffs, I can't figure out a way to mount it. I was thinking of something to grab the sides but still leave a air gap. How have you solved this problem?

The simple way to mount the boards is to use additional hardware. Instead of using the supplied screws on the underside, use longer screws and spacers. Then the PCB stack can be mounted to a plate or the base of an enclosure. I have attached a picture showing the supplied hardware replaced with longer screws and spacers.

More standoffs.

By now you probably figured something out. I used the included female-female standoffs between the rpi and CNC board. I used Male-female standoffs to fasten the stacked boards to the enclosure and to maintain a little air gap on the bottom side of the rpi.

I've just been looking at the same challenge.

My proposed solution is to replace the screws through the Pi with ones long enough to allow spacers. The main question at this point is what the thread of the current screws is. I'm of an age where I would use 4BA but suspect these are metric?

They are M2.5... ;)

I found some assorted standoffs with a male and a female end. I have it so that it is raised up about 1.5". I need to make an adapter so I can mount it over a 12v fan. Thanks for the replies.

How about just put the whole thing into a case with cooling fans?
I've already designed a case with many different options to choose from.

No, I made a couple changes last week to them. When doing my wiring I ran into a problem trying to find the right cable for the ps2 style circular connector that plugs into the outside of the case (for the front panel switch wiring). So I ended up changing the round hole to a rectangle so you can insert an easy to find JST style connector which will also give you more wiring options.
I don't have time right now to write out any instructions or hardware list, but if you need the case right now PM me and I'll send you a link to the files.
