KlipperScreen is either waiting for printer information or does not show the temp graph

Frontends KlipperScreen
1

Hi folks,

black week tricked me into buying a BTT Pi TFT50 so that I can use KlipperScreen on my CoreXY. :smiley:
I really like it but there are still two minor issues where maybe someone here can help me.

When I power on my printer the TFT showed the KlipperScreen main window with the text that it cannot read printer information. When I hit the retry button on the bottom right all is working fine.
During my research I found a tip to add the following line:

ExecStartPre=/bin/sleep 10

into the klipperscreen.service

Initially this seemed to work but now I had to increase the time to 15 seconds…
But with this fix the temp graph is not being displayed by default:

20221219_164754
20221219_1647541920×1440 180 KB

If I enter any submenue and leave it the temp graph is present…

Does anybody have a tip for me?
Is the initial startup issue normal? And is the fix an elegant one?

Thanks in advance!

Looks like with delaying the service for 20 seconds it is working fine now.

I tried adding

Requires=moonraker.service
Requires=klipper.service
After=klipper.service

in addition to After=moonraker.service but didn’t make any difference. The delay you suggested works.
