Hi,

Is the firmware you downloaded and edited also have the changes made for the printrbot? ie mainboard, exturders etc?

When you say it's blank, does it in fact have 2 lines of squares on? It sounds like the connector is the wrong way round if all you get is a backlit screen and nothing else.

Sorry for the time it took fo me to answer, was out of town..

The two lines about EEPROM are uncommented from the beginning.
It should work, but for me it doesn't... :/

I'm i plugging in my LCD right?
I got the Panelolu2 and it comes with a adapter called Printrboard adapter v0.1 And it fits over the Exp1 and ICSP connectors. But what i can find you're supposed to plug your LCD in Exp2 and the Extrudrbard goes in the Exp1.

I bought it from makemandel.com and they said "Connect LCD to the "EXP2" slot on Printrboard." on their page. Under this picture...
They are clealry connecting it to Exp1
I'm connecting it like the picture but i am not getting the lcd to display what i want.

Can you post a picture of your set up, front and back?

Yes it is suppose to plug into EXP1, and as i have just found out i don't think you can use the Panelolu2 and a dual extruder board :-(

I see from your other thread you can get the new firmware uploaded to the board, is that correct? If so how can you say that the correct changes have been made to the firmware, i'm confused here.

I just switched from a Printrboard/Panelolu2 combo to RAMPS/RepRapDiscountLCD combo last week and all was fine with me. The only changes you should have to make are uncommenting the Panelolu2 LCD line in the code.

You need to make sure you have the LiquidTW2 Arduino libraries, which you do, but you also need to make sure you are using the correct IDE version for it.

Have you tried downloading a different Marlin version and testing it?

Hey thought you folks might be interested. Makemendel.com which sells the Panelolu2 LCD just offered to add the LCD connection code to the default Printrbot Rev F software (for the Simple Maker's kit) for me. Which means, no Marlin but still LCD. Yay! If you're not using the Simple Maker's kit, I'd bet they'd be happy to add it to the stock software for your version as well. You just need to send them a copy of the current software, which can be found on Printrbot.com in components on the Rev F: http://printrbot.com/shop/printrboard-rev-f/
Pretty great of makemendel if you ask me! Although I did just spend almost $200 on stuff on their store :lol: that might help. Especially if you buy the Panelolu2 from them (received mine today, looks great so far!) I'm sure they'd be happy to. I'm extremely impressed with their customer service.
PS: no this is not an ad, I am not affiliated with them in any way, just a happy happy customer :D )
