Hi Folks,
I have a smoothieboard and RRD GLCD which were getting along fine until I switched to my new bigger PSU ( that can cope with my new 200W hotbed).
Now the LCD doesn't seem to be initialised properly, I get a couple of lines of random dots instead of text.
Every now and then if I power up then off then on again I get a proper display.
Switching back to my old PSU makes everything work again so I'm suspecting there is a problem with the rise time of the voltage being too slow and reset not happening smoothly.
Has anyone else had this problem and did they solve it?
cheers,
Robin.
