Questions for Firmware update

[essen2005@gmx.de]

Hi All,

I have updaste the firmware to the Marlin 2.04 on my A20 and have a view question now.

1. The BL -Touch sensor releases too early, so that the pin touches the print bed while the print head is still moving up. Can you set a delay?

2.Can I set the number of fans in the temperature menu. I see 3 fans, but the print head has only one fan.

Many thanks in advance for your help.

Kind regards
Stefan

Hi,do you calibrate the bl touch,
Regarding fan control,
Only the fan on the extruder housing can be controlled, the rest are cooling fans,
The printer is always on when it is turned on.

What do you mean with calibrate BL touch?
I know about teh fan, but I mean by default there are 3 fans to control in the tune Menue.

kind regards
Stefan

Yes, I did this.
And in generel the BL Touch is working.
It just releases the pin to early - the pin is releaed while the head is moving up and the pin touches the bed during that move.
Therefore I would like to delay the release of the Pin a little bit.
