Z0 doesn't respond

Simon_MRodriguez · April 28, 2025, 8:44pm

Hello everyone.

I have built my Lowrider 4 with a Jackpot CNC Controller, and everything seems to work perfectly except for the Z0 axis, which doesn’t respond. If I swap the motor to the B axis, it works without any issues. When I run the $SS command, all the drivers are detected correctly.

Does anyone know what could be happening? Thank you

Dreyfus · April 28, 2025, 8:55pm

Can you post the response to $SS please? Have you also tried a different, working stepper driver board in Z0?

Agreed that $ss lets us know a lot of things, most importantly here, is the right firmware.

No idea why that would not work, it all looks good.

Seems like you have had that board a while, might be worth updating it. Jackpot CNC Controller - V1 Engineering Documentation

Simon_MRodriguez · April 29, 2025, 7:43pm

The board is new, I received it three weeks ago. I got it from Elecrow (I’m in Europe).

I tried installing FluidNC version 3.9.1 and loading the V2 configuration with the macros, but none of the axes respond. Which version do you recommend?

vicious1 · April 29, 2025, 8:24pm

Full erase, use 3.9.1 and if it is still funky. Power down and swap the drivers to see where the issues moves.

Simon_MRodriguez · May 2, 2025, 10:40am

Hello again! I’m still not making any progress… When I try to update FluidNC to version 3.9.1, I get the following message: ‘Error: 500: WebSocket dead.’ Can anyone tell me what I might be doing wrong? How can I completely reset my Jackpot before reinstalling FluidNC?

Dreyfus · May 2, 2025, 10:46am

Ok, that’s different from above where you’d loaded 3.9.1And macros. So can you confirm step by step what you’re doing when trying to update?

Are you using a known good USB cable that supports data - some are power only
Are you removing the esp32 board from the jackpot board or updating it in place
When you plug the esp32 into your computer does it appear as new hardware
Have you ever updated any esp32 or esp8266 devices, it not you might need the drivers installed
Are you using the web installer or another method

Simon_MRodriguez · May 2, 2025, 10:57am

With the ESP32 on the Jackpot and disconnected from power, I connect the USB cable to my computer (Mac). Using the FluidNC web installer, I connect, select ‘Install’, and choose version 3.9.1 — the one that completely erases the existing version. Then I copy all the macros and files from the V2 folder and paste them. I restart and disconnect it from the computer."

Dreyfus · May 2, 2025, 11:01am

When are you getting the websocket error?

Simon_MRodriguez · May 2, 2025, 11:06am

When I connect the Jackpot to power and try to connect to the Wi-Fi through my computer using the FluidNC interface.

Tokoloshe · May 2, 2025, 11:26am

Did you unplug the USB cable before? I think it can’t be plugged in for that.

Dreyfus · May 2, 2025, 11:29am

When you flash it can you ckick the ‘More Details’ drop down and post theinstall log? Should look something like this:

hi in webui V2 can you post a screenshot of the screen first?

on webui2 you need to: have any methotd of reporting selected first ( you wont get any movement if not)
then
clear any alarms and home the machine

Simon_MRodriguez · May 2, 2025, 2:45pm

Thank you for your suggestion. I tried selecting Auto and pressing the alarm button, but it still doesn’t respond. When I enter the $SS command, I get the same error message again: ‘Error: 500: WebSocket dead.’

CesarH · May 2, 2025, 3:00pm

The 500 error after you reverted to WebUI2 could be an instance of this problem that is mentioned in the release notes for the test release: "If you use WebUI3 and then go back to WebUI2, WebUI2 might not start correctly. If you have this problem, you can fix it by deleting the preferences.json file with $localfs/delete=preferences.json . The problem is caused by WebUI3 creating a new preferences.json that is in a format that WebUI2 does not understand."

This is from the fluidnc discord help forum
$localfs/delete=preferences.json

Try that and restart your controller

Also, are you using ap mode?

Suerte
