Geeetech

in Marlin firmware.

Try change parameters in cofiguration.h file to 275°C: // When temperature exceeds max temp, your heater will be switched off. // This feature exists to protect your hotend from overheating accidentally, but *NOT* from thermistor short/failure! // You should use MINTEMP for thermistor short/failure ...

Yes for both questions. LCD and mesh working fine.

In my opinion there is only lack of mixing features, the others either do not need it or they are easy be created using a macro.

I have z-stop disconnected too. Try invert this settings: pin_up_reports_not_triggered: False pin_up_touch_mode_reports_triggered: False .... maybe this settings usable on cloned versions of bl-touch sensor. I have 3d-touch clone from Geeetech and have occasionally problem with bl-touch in next prin...

Thank You very much for opening my eyes. I'm modify your printer.cfg file for my A10M with BlTouch copy. Klipper is far better firmware than Marlin. My settings is in attachments for Cura and for Klipper. Sorry for my English.

Frequency of speaker is changeable using the G-code .... S: frequency in Hz, P: duration in ms. Easy usable in start and stop code, but only without sticker.

M851 Z- is limited to 3mm in some firmwares.

I removed the sticker from the speaker (or beeper) in my A10M and the volume level is much higher. On sticker is label : Remove after washing. Probably the Chinese assembly line operator does not understand it. I've seen many photos here where the sticker has been stuck.
