I just saw that you just posted this on the Klipper Discord Forum. I’ll be interested to see what the experts there say.
The Creality Sonic Pad uses a fork of the Klipper host software (and KlipperScreen) and does not generate a klippy.log file. From what I’ve read, when it works, it works great. If you have a problem, you have a real problem as support is not great for the product.
My recommendations are:
- Make sure you have the latest Sonic Pad firmware. Apparently there was a new release about a month ago.
- Install (the Creality) Klipper firmware on your printer. I know that Marlin is “supposed” to work with the Sonic Pad but I’ve heard of other people having problems that were resolved by going with Klipper firmware.
- Putting Klipper firmware on your printer means that you’ll probably have to retune your printer and work through the printer.cfg but Creality has a default printer.cfg for the Ender 3 (or at least should have) so that should reduce your workload.
Sorry, I can’t give you better news - let us know how you make out and I’ll watch the Discord forum.
