Re: Smart controller screen unreadable, Marlin setting or bad screen?
That's what I feared, that potentiometer does next to nothing. The video shows it in it's most optimum setting, in only gets worse if I turn it the other way. Hugo

That issue is well known,,, this issue is that they have a contrast on the lcd module (where you cant get to it) and on the main board... they should have removed the one on the lcd... I know of two...

Well, I just tried all solutions in de linked topic, to no avail. I also measured all voltages everywhere I could, they are all OK. I think I have a faulty LCD... Bummer... Hugo

This is entirely possible, though I believe Dust is correct and it is just a back-light problem. More information here [reprap.org]
View ArticleRe: Smart controller screen unreadable, Marlin setting or bad screen?
The other common reason for poor contrast on Arduino Mega/RAMPS setups is that the 5V regulator on the Arduino is not capable of powering the Arduino + 12864 display without overheating. As a result...

Well, it looks like the backlight is well adjustable, but the graphics just aren't clear... Hugo

Erkaiden What board are you using? If you are using ramps I would appreciate if you would upload the wiring.

Hi TonyFran, this is the wiring: I use a dvr8825 for each of the two motors of the z axis (the y axis is equal to the x axis)

I already replaced my Mega's voltage regulator with an LM7805CV, rated for 1,5A (and it can take 24V). And I have the same result when I power it over USB, with plenty of power over the 5V available....

View ArticleDifference between extruder MAXTEMP variable and temp you can set the hotend to
Just a quick question about the maxtemp variable. When this is set to a given value, when I heat up my hotend manually it can only reach a value 15 degrees below the MAXTEMP setting. I just wanted to...

Yes I think with any pid controller if you want to reach the desired output quickly and not wait for ages you will have to overshoot it first, so it makes sense to have a 15 degree so that the machine...

It's entirely possible to design a PID controller that doesn't overshoot significantly. However the PID constants you need to do that are not optimum for maintaining the temperature once it has been...

well done re testing. you could just "print" a gcode file that has one line, turn on the fan, so you can see the mosfet led turn on
