Text is lasered, PNG breaks off

[yamu93 (Yanick Mumenthaler)]

Hi

I have a problem with my laser and lightburn. I The laser is a Creality 10 watt cr laser Falcon. When I write text directly in lightburn, it lasers it beautifully. But as soon as I import a PNG file, the laser shows me the frame on the object, but as soon as I press start, it just goes back to 0-pisition xy and does nothing. Can you help me? Is there something wrong with the Lightburn?
There is also a message on the console: [0;31mE (65372) gpio: gpio_isr_handler_remove(480): GPIO isr service is not installed, call gpio_install_isr_service() first[0m

@yamu93

GPIO isr service is not installed

This may be a controller firmware problem:

Laser homing frequently hangs Lighburn

I followed up with Creality and asked for the previous firmware version. They sent me 3.0.20, so I downgraded from the 3.0.24 current version, and the Falcon is flying! I can now home repeatedly without a lockup and the Console returns abundant data (see below). Even the cuts look cleaner. If you have a Creality CR Falcon 10W and are having problems like the above, it’s probably the firmware. Thanks again @berainlb ! $H b dir:3 head:21 tarx=-660.000000 tary=-660.000000 xmm=-52800 ymm=-52…

The Creality support folks should have more details on what’s going on and what will fix it.
