[btc to the moon]

hello, i got it just new out of the box and i couldn't print any thing yet because the whole freaking machine doesn't take commands and if it decided to take commands to level the bed ,it reverses the z axis and the nozzle just keep going down non stop until it hits the bed and keep pushing it non stop then a beeping sound comes off and the motor and just keep forcing the nozzle down I need help, I tried updating the firmware with no success, then I opened the forums to check if someone got the same problem i found that the screen got an sd slot which I checked in mine and it had no slot what so ever so I bought a 4 gb sd card and added it emply to the screen sd slot and turned it on the machine for the first time stated to me that there is a problem in reading the code or something like that i forgot the actual sentence then i uploaded the UI provided by u guys and boom i have BLACK screen, I swear I didn't even got the chance to print the freaking doooooog.

Hello, please contact geeetech's ticket system for official help.

Regarding the reversal of the Z-axis of the printer, it may be a wiring error. You can exchange the wiring sequence of the motor to see if the Z-axis can be restored to normal.
Regards.

Hi all.

While dinking around with my display, I managed to jank my LCD so that the top row is blank and the second row is incomplete.

I ordered a replacement from Geeetech and, as stated on their purchase page, noted that I needed the LCD for the GT2560 V3 board. I received the replacement but when I connect it to the display cable it shows only two solid bars.

What am I missing? Do I have the wrong LCD?

Yes, I am sure I have a V3 board. I'm running Marlin 1.1.8.showbox speed test
