RRD Full Graphic slow display update Hi, I got a problem, my RRD full graphics display seems to have quite a slow update upon navigating the menu, for example pressing the knob will enter the main menu, but turning the knob from info screen to prepare, would have the screen goes blank for about 2-5 seconds before it appears back, this happens only when turning the knob to navigate through the menu lists. My current electronic is CH340 Arduino Mega 2560 ramps 1.4 drv8825 step stick marlin rc3 1.1.0 with ramps 1.4 efb board profile selected I tried with a spare full graphics controller board, it seems both having same issues, is it the ch340 mega or marlin itself?

My current electronic is

CH340 Arduino Mega 2560
ramps 1.4
drv8825 step stick
marlin rc3 1.1.0 with ramps 1.4 efb board profile selected

I tried with a spare full graphics controller board, it seems both having same issues, is it the ch340 mega or marlin itself?

Thanks in advance]]> sarf2k4 General Tue, 12 Jan 2016 04:24:25 -0500
