You need to update your firmware
However this should be only a debug message not as much as an error

Is your machine homing, and engraving correctly?

If you still see this message after updating your firmware, this r/Creality Reddit thread suggests contacting Creality support for a GPIO service file.

Sadly, if its a Creality CV-30, the firmware was not patched - yet - to fix this gpio issue

@Creality_Rachel is aware and informed R&D

A update is expected “soon TM” :smiley:

Hi
To resolve that problem instal this:

Product Firmware
CV-30_V3.0.20_20220427
:slight_smile:

The latest firmware CV-30_V3.0_24 have some kind of bug. I had the same issue with GPIO.
Few night with coffee and I resolved that problem :blush: ufff

So a downgrade on firmware?

Exatctly downgrade

10 minutes ago I found and loaded the software into the laser:

CR-Laser_Falcon_User_CV-30_Firmware_V3.0.23 - 08.10.2022

And the same GPIO problem. So I again downgrade firmware :slight_smile:

8

well they do specify which version to downgrade to
Maybe you can read change log and see if you miss anything by doing so

It seems to me that this is a problem with the control device. I suspect that the “latest version” of the software is not compatible with the device’s motherboard. We have an older version of the motherboard. The newer motherboard is probably located in:

Downgrade to CV-30_V3.0.20_20220427 and have fun with LaserBurn 1.60 :slight_smile: beta

BTW… I have 2 full sets of Falcon 10W (order from Aliexpress - they send me 2pcs :shushing_face: but I ordered only one)

On second device is the same GPIO problem.
