I wanted to ask for some help with Printflow3D.
In maintain.html page there is Test Calibration button which sends pictures to the screen.
Since screen has got no original backlight I need to send M106, M107 commands to activate backlight while displaying images.
Do you know guys how to send gcode via serial from Printlow?
Should this be edited:
onclick="$.getJSON(’…/services/printers/showGridScreen/’+printerName+’/50’);" /> ?
I am thankful for any advice!
