Switching control boards

Mostly Printed CNC - MPCNC Troubleshooting
1

When I bought my jackpot the original one it asked how I wanted it to be configured and I checked MPCNC it was plug-in play. But fluid NC would continuously crash. It was unreliable and messed up so many jobs. I gave up on it and was running cndle with a USB cable and it worked flawlessly. Unfortunately, on one job I had tripped over the USB cable for my laptop and ripped out the connection to my laptop breaking the connection off the jackpot board.

I decided to spring for the jackpot 3 I plugged it in thinking that I could just transfer the motors to the new drivers as labeled in the instructions. Nothing seems to work right I can only get my Z access to move.

Back to fluidnc now that I have a new board. The XY axis are totally impaired. I noticed that the Y access would control the X axis, but only one motor. Clearly the instructions were not lining up. I started to switch connection connections around to see what would happen. And now I can’t get any motors to run.

I’m just so disappointed

Hey Danny, a picture of your Jackpot as well as the yaml would help troubleshooting immensely. :slightly_smiling_face:

With the Jackpot you had before it might have been the version of FluidNC that was really unstable, it has improved a lot by then.

@cncdhg here is the most current config for the MPCNC running a Jackpot 3:

I’m 99.9% sure that Ryan sends out all the Jackpot 3 boards with Lowrider config unless you email him when you make your order.

@vicious1 can you confirm this? And if I am correct, might be a good idea to put a note for that on the product listing.

Upload the config that @Britt linked, double check your wiring is per the docs, and you should be good to go

When I went in the settings it looks like it’s setup for low rider and I guess I had expected it to be setup for either since my first jackpot had me specify my machine when ordering it.

I’ll look through these resources. I am trying to get this up and running for this weekend. My 9 year old is learning fusion 360 and he has some designs he wants to try to make.

If you run into any questions along the way post them up and we will help get you going. That is an awesome reason to want it running for sure!!!

Please note that if you just bought Jackpot board from me without buying a hardware kit as well, I have no way of knowing what sort of machine you are using it for unless you emailed me prior to your order. No reason to be disappointed I promise. In your case the fix is simple.

There is a troubleshooting section in the jackpot docs page. If you type $SS into the terminal does it say Lowrider or MPCNC?

I do not sell MPCNC kits any longer so I only flash Lowrider firmware since switching is simple, as JJ mentioned.

BUT…have no fear you simply need to upload one file and restart your board. Britt gave you the link, upload the jackpot 3, mpcnc, config.yaml to your board using the webinterface, or USB cable and the webinstaller, then reboot your board. Boom 100% mpcnc now, easy as can be.

What a bummer.

As others noted, with the Jackpot, you just upload the correct config.yaml and reboot- and there you go.

Note also that your Jackpot V1 has a replaceable ESP-32, so if you break the ESP-32’s USB connector you can just replace the ESP-32, re-flash it with the web installer, and you’d be back in business.

The Jackpot V1 and V3 electronics are slightly different because of improvements on the V3- which is why you need a different config.yaml in the first place.
