WebUI

What happened?

With the latest version from Github (Main [e89add3]), If I trigger a home from Fluidterm or Lightburn -> everything is working fine If I trigger a home from WebUI, motor speed is random and very often very very slow, then end stops are not detected, home is failing

[MitchBradley]

I am working on it. I should have a fix soon

[MitchBradley]

It is fixed in the MSG_JSON branch. https://github.com/bdring/FluidNC/commit/674b0df0d5fb33c567c11544304de6cae1731908

[Avataar120]

It's working perfectly on my setup ! Thx !

[BlueOrangeLive]

Hello Avataar120. Can you test whether in the WebUI if you have a job running, pause it and then stop it or then let it continue running.

[Avataar120]

Hi, you're right. Pause is working, but resume has no effect. Impossible to resume the job

[MitchBradley]

I'm working on it.

[MitchBradley]

Fixed

[Avataar120]

Working !

[Avataar120]

Hi @MitchBradley ,

In fact, lot of instabilities I don't have with the previous versions (in USB mode with gcode sender) For instance : SVG is only a circle, FluidNC will pause for few secs 3 or 4 times along the path, or the program won't start.

I reopen the ticket to avoid merging in Main without more tests.

Unfortunately, I have to leave for tonight. I'll make more tests tomorrow to give you more infos.

[Avataar120]

@MitchBradley I do confirm the issue when streaming GDCODE through USB.

Steps to reproduce : Latest MSG_JSON firmware ([11f5d18])

Home ($H) -> OK Frame (see GCODE below) -> OK G00 G17 G40 G21 G54 G90 G1 X136Y125S0F12000 G1 Y231 G1 X38 G1 Y125 G90

Simple circle. GCODE sent through Lightburn. GCODE attached -> NOK circle.zip

No movement at all, USB connexion seems to be dead, not possible to send any command to the ESP32, ...

[MitchBradley]

I have reproduced the problem. In my setup, it only fails when using Lightburn buffered sending mode. Synchronous mode works fine. That provides a clue to help me track it down.

[Avataar120]

I'll try it tonight CET after going back home. Thanks !

[Avataar120]

I tested both WebUI and ligthburn (buffered) and everything is working fine. Sync mode is working fine as well. I think this is the good one !

[MitchBradley]

I made some improvements about half an hour ago. They work great for me, but it would be good to get some additional testing.

[Avataar120]

I think I have tested the latest one ("v3.7.12 (MSG_JSON-71a1c460)")
