Flashing touchscreen after power down, this normal?

Postby Will » Thu Jan 05, 2017 3:27 am

Does anyone know if this is normal? When you switch the power off button in the back of the n2 plus, the startup screen turns black and boots up again. It will continue for a few min then flash white for another few min then turns off? I'm assuming it continues to flash until the battery dies. Is this normal? I notice my battery level was at around 30%. this was my first power on and off. Any help would be appreciated. the two flashing screens are below:

You must leave the printer on for the first 12-24 hours to charge the battery after shipping. The battery does not charge when the machine is off.

Basically, yes, you messed up and while not explicit in the instructions, this has been mentioned quite a few time here and I've even said, they need to put a big fat warning sticker on it for you new users.

"The problem" is that you failed to allow the LCD and pcDuino controller battery to recharge after shipping. The battery only recharges when the printer is on. The battery self discharges over time and during the long ride on the boat and sitting in storage, your battery was nearly dead.
The LCD is an entire mini Linux computer that has a battery not unlike a laptop. The power switch only controls the main 24V supply. The front LCD senses when the 24V supply is turned on, there is a secondary delay board to ensure the PSU is really on and stable, and that in turn tells the pcDuino board to turn on. Thus, there is no "direct" power switch on that tiny little computer. When the lithium battery is low, it cannot run long enough to properly shut down the operating system of the LCD screen making it loop or flicker.

One of 3 things is going to happen:
The first is, the battery will just run down until the battery management system (BMS- a tiny circuit board on the battery) finally says enough is enough and interrupts the battery from powering the system.
OR
You follow the instructions to open the control panel bay and unplug the battery
or
Don't turn the printer off for the first 24 hours to allow the battery to charge before attempting to turn off.

The screen will not be damaged but you really shouldn't let the battery run down flat either.
So turn it on and walk away or keep printing for the next 24-48 hours.

I really think there should be a big fat warning piece of paper over the front panel that says power on for 24 hours.
Maybe a section in the manual that tells the user to turn the printer on at least for a few hours every week and monitor the battery charge state, do not turn off the printer if the battery is low.

This is because any other fixes are a major change to the electronics. It works the way it works. It works fine in most use cases.
It's when you couple new user, discharged battery, and you get the "I'm caught in a reboot loop".

Thanks for the info. It was only confusing because I didn't find any information about it in the box. The Raise team were quick to respond and mentioned the same solution. Thanks all for your help.

WHAT if my battery =dead= and does not function as it should.
I have six N2's and they all works differently =)
some of them turn off immediately (i think no battery here), some with 1007 error, and a few - correctly shuts down and turn on.

May I change only the battery? With what? Thanks!

3.7v 14.8Wh battery.
battery is terminated in a JST XH 2 pin connector. Ensure polarity matches as shown and compare to your original battery.
The size in mine is 606090 however since it's just sticky taped to the back cover, any reasonable size should fit.
