I’m in the final assembly phase. My RAMBO board will be here tomorrow. (Full RAMBO, not the mini) Then I can get everything wired up. I watched a video on Youtube of someone who built this MPCNC and he added a “pendant” which is basically a joystick that allows him to quickly and easily move the head around the work area. Where could I get something like that which would work with my RAMBO setup?May 27, 2019 at 10:24 am #101770
It is a bit complicated as Marlin is not set up for a real pendant. In my opinion the best control would be to use Jeff’s V1Pi, and your cell phone or tablet as a control probably much cheaper and easier than any of the pendant’s you have seen running on marlin.May 30, 2019 at 9:27 am #101999
I watched the Youtube video of the guy that built this and he used a really nice joystick that worked great. I picked one up for $28 on ebay. It just plugs into the USB port on your computer. It says that it works with any board. But apparently, not any firmware. If I have to reflash the firmware to a compatible one, maybe that’s what I’ll do.May 30, 2019 at 9:39 am #102000
Can you provide a link to the video?
The easiest way would probably be to use the rpi v1pi setup like Ryan suggested. The v1pi comes with cncjs which appears to have some pendant support: https://cnc.js.org/ My wireless keyboard has become my clunky pendant.
I thought it would be a fun project to build an arduino based pendant that just taps into the rambo’s serial tx/rx, but that’s certainly more involved.May 30, 2019 at 2:31 pm #102036

I’ll think about that guys, but it looks pretty complex. I’ve dealt with Octoprint before trying to use it with my 3D printer and I hated it. I struggled for a LONG time and ended up giving up. I’d rather not go through that again.
In the long run, I think using a different firmware would be much easier. This joystick just plugs into the USB port and you’re good to go.May 30, 2019 at 3:30 pm #102038
v1pi gives you the option of using octoprint or cncjs. Maybe cncjs would work out for you.May 30, 2019 at 3:33 pm #102039
Here’s the video.
Oh yeah, I’ve seen that before. He’s using a much more involved mach3 setup than our Marlin RAMBo boards.
If I remember right he’s got several cnc machines in there, I got the impression he made the mpcnc just for the heck of it using leftover electronics from other builds.May 30, 2019 at 6:31 pm #102060
