Is there a temporary problem on firmware builder?

Marlin Firmware Service Firmware Builder
1

Since I upgraded my Ender3 V2 to 350mm high, I created two firmwares on 19th and 23th of May, when I had no filament runout sensor. Both firmwares are okay with 4.2.7 board.

Now I got filament runout sensor and want to create a new firmware, I always get Error without explaination, compiling fails.

May I ask if there is a temporary problem on servers /builders?

Thanks for help.

Yes. There is currently a problem with the ProUI code that causes the compile to fail.

I’m looking for a temporary fix until it is fixed properly in the Marlin repo.

I may have found a fix in the meantime. Can you try building a custom firmware now and see if it works ok?

4

Okay, compiling success, but printer is busy for next 7 hours. I can not check right now if the firmware works. I’ll report it later.

Thanks for your concern and support.

Unfortunately printer can not see the file as firmware and it can’t be uploaded to printer.

Try the normal troubleshooting - rename the file to a different filename, try reformatting the SD Card etc etc

See the Flashing Firmware section of the Ender 3 V2 FAQ.

I already tried all of them. Firmwares, dated 19th and 23th May can be uploaded but the latest ona can not.

Well, I’m not in rush. :slight_smile: I had no runout sensor for more than one year, it may wait a little bit longer. I’ll try time to time. I’ll be in touch.

Many thanks for support.

Well, today I built a new firmware, compiling okay, uploading to printer okay but can not print. When I choose a file “thumbnail not found” appears. Can’t be seen but seems there is a confirm/Cancel screen background, only frames appears when I wheel the button. What do I do wrong?

Recently, support for G-Code thumbnail images was added to the UI.

Even if you don’t use OctoPrint - this link has guides on how to set that up for each slicer:

I did explained procedure for Cura and created a post processing script.
Still “Thumbnail not found” appears and printer waits. In case I turn the button counterclockwise, a rectangle jumps from right to left, and printer starts to proceed printing when I press the button.

What is written in rectangles in right/left sides, I don’t know, probably “cancel/confirm” or “abort/contuniue”.

Let me try and chase this up and see what I can find…

Have you tried the MarlinUI builds in the meantime? They might be more suitable long term…
