Problem With RepRap Discount LCD Controller

Hi all,

I have a gMax Printer currently at work, i am using it to build my own printer for home. I'm using the gMax Marlin firmware, however i can't seem to get the LCD controller to work properly.I havn't got any of the motors or sensors plugged into it yet and was just getting it set up and used to how the firmware works.

The LCD lights up and gives me the MINTEMP error, however when i click the encoder button to enter the menu nothing seems to happen, the screen just refreshes and stays the same, theres no way to get into the menu.

I've been through loads of posts but can't seem to find the problem it seems as if it is set up as it should be.

Any help would be greatly appreciated.

Thanks

Alex

If you have chosen the right motherboard from marlins boards.h, you can now install the thermistors to get rid of the mintemp error. Then the LCD opens up a few more sub-screens.
To see the whole screen structure, you have to add all components.
SD-Card only shows up, when a card is inserted.
EEprom has to be enabled to see the eeprom menue, etc...

Olaf,

Thanks for your reply, i will get the sensors wired up and update.

Ok so i got the encoder working (kind of), i can adjust the print speed from the info screen using the encoder, and i can also click into the menu. However once in the menu i cannot scroll through the options? Is this because i have no Motors or End stops connected? Also once i have clicked into the menu, the encoder will not work at all even to adjust the print speed.

Thanks

Motors won´t be recognized by the mainboard, it´s "open loop ".
But endstops will have a big influence ofcourse.
There is a Marlin test software, that allows you to test your steppers without endstops. (aaargh, were is the link, when you need it?)

Well even after wiring up all of the End Stops, the encoder still does not work on my controller. Running out of options now unless its no good the item itself

Can you post your configuration.h as attachment please?...
LCD is a tricky section in Marlin, maybe you haven´t disabled something...
