New Build - Jackpot Port Issues

Mostly Printed CNC - MPCNC Troubleshooting
1

Hi all! First off, just wanted to say I’m fresh to the community here and building the MPCNC has been such a joy, so thank you to the team who all made it possible!

I am at the step of connecting all the end stops, stepper motors, etc to the Jackpot controller, playing around with FluidNC to test that things are in working order. However, I’m having an issue where the steppers connected to the X1 and Y1 ports are not moving when jogging their relevant gantries. At that, the stepper plugged into the Y1 port is jogging when the Z stepper is jogged.

For Troubleshooting context:
-Jackpot was purchased from the V1 shop, with the option to preload MPCNC firmware
-Steppers also purchased from the V1 shop
-All steppers have been tested in the X0 port to confirm that all are functioning, and do.
-I tried flipping the connectors and re-seating them when checking the X1, Y1 ports.
-Endstops also have been tested and work.

I ran the $SS command in the terminal, as was recommended, and unfortunately I do not have that with me to post (yet) because the tablet I was using ran out of juice before I could copy it. However! I did notice that there was a line that read Machine: LowRider, which makes me think perhaps the wrong firmware was loaded onto the Jackpot?

Additionally, in the wiring diagram is shows there is a slot for a Z endstop (X0,Y0,Z,X1,Y1,Probe) but I reviewed the build documentation and I didn’t see a step where a Z endstop is installed. Perhaps I just keep missing it?

Thanks so much for your time reading this! It’s much appreciated :slight_smile:

Order number? A bunch of orders recently have had mismatched firmware from the machine in the actual order so I just fulfilled it like it asked.
The fix is easy just upload the MPCNC config OTA and it will reboot as an mpcnc controller.

None gets installed, MPCNC don’t use them, if you want some Z control you can use a touch probe.

Hey, saw you in Discord. Welcome to the forums.

In case you need a bit more direction to load the MPCNC config, you want to download the config.yaml file from here:
FluidNC_Configs/MPCNC/UI V2 MPCNC at main · V1EngineeringInc/FluidNC_Configs

Then you can upload it in the WebUI by selecting the FluidNC tab and the green folder button where you can upload the file.

Ryan! The man himself! Thanks so much for your quick reply. I’m relieved it’s as quick a fix as uploading the right config, rather than a manufacturing issue with the board.

I am order #26924

Hey Jason! Definitely appreciate you pointing me in the direction of the forums. Thanks for putting the link to the config file.

I just want to make sure I’m understanding correctly, so order of operations is as follows:

  1. Download config to my device.
  2. Upload config to WebUI directly from my device via green folder button. Does uploading the new config file replace the LR config, or do I need to do that manually?
  3. Power down Jackpot and restart. Is there a power down command/button, or is it simply just unplugging the Jackpot?

Yep, you got it.

It will automatically replace the existing file.

I usually just cycle power. Technically, you can run [ESP444]RESTART in the terminal.
