How to install the firmware for GT2560

Pat,
About Y and Z motor issue,i guess you may have those two endstops correctly connected(should be Y_min and Z_min).

LCD problem,you only can see X and Y when you click on "Move 10mm" but you'll see "X/y/Z" when clicking on "Move 1mm".That's normal.

Hi,Pat
Why not download the firmware for your own printer(proB)...

Sorry for my bad english.

I hava geeetech i3 pro b.
I have installed arduino 1.0.1
I have downloaded the firmware Marlin
I have setting arduino mega 2560 board.

5) Firmware for I3 pro&proB
I3 pro&proB(GT2560)

Marlin-PI3_Pro_B.zip

When i compile, not install only compile,return many compilation errors .

attaching file with errors
Thanks

Hi Babau.
It seems that you are missing the U8glib library file from your installation of Arduino 1.0.1. The zipped file is attached below. Just unzip the U8glib folder into the library folder of Arduino and restart Arduino. You might check that it is imported in the import library... item of the sketch drop-down menu. Marlin-PI3_Pro_B should then compile without errors.
Cheers.

Acrylic Geeetech I3 pro B 3D Printer kit

I need some help.

Assembled it correctly but the z axis does not stop after it pushes down the z axis minimum button ( I hope that is how you call that)
I have the same issue in the case of auto-home also same when I set the home setting manually. The motor keep stopping at the end point and is forcing itself but it will not go any further.

I hope you understand my issue.
Thanks in advance

Are you driving the Z-axis steppers independently using separate drivers (Z2 option)? If you are you may need to add a line of code to define the home retract distance for Z2 in the Configuration_adv.h file of the firmware.

Hi there from Greece!
I recently bought a Geeetech Prusa i3 pro B 3D printer (great kit by the way).
The printer works ok by itsself (if I use an SD card I guess). I mean, I run some "tests" from the display (moving axes, heating bed and extruder) and it worked ok, except the x-axis that is inverted. I know how to invert it with firmware, I've read that part. I also need to make some changes to the firmware so my auto-level kit can be used. I've got some usefull instructions on how to do that too.

My problem is that I'm having some issues connecting it to my PC.
I tried that on 2 seperate machines, one with Windows XP SP3 32-bit and one with Windows 7 64-bit. Failed to connect.

I've plugged the usb cable, device not recognized (that's ok, it needs drivers).
I've installed the FTDI drivers as mentioned. Device manager shows Serial-usb on COM4. Green led on GT2560 board.
I installed arduino 1.0.1, used the correct port and board (I have the GT2560) but arduino gives me lot of errors.
I extracted the "U8glib" folder in the library folder, errors appeared again.
I installed arduino 1.8.1 (latest) that also gives me errors.
I have attached a zip file with errors.
While uploading the firmware, I can see an orange led flashing on the GT2560 1-2 times then stops. During that my prusa's display goes off then on.

Any ideas?

@ kovac_00
Try this driver:

And could you please attach a picture of the FTDI chip on your board?

First of all thank you for the quick reply!

YES, THAT DID THE TRICK! WORKS LIKE A CHARM NOW!!!!
I've been using the "CDM v2.12.00 WHQL Certified" driver as refered to the instructions and I was pretty sure that it was ok (I also downloaded the "CDM v2.12.24 WHQL Certified", but didn't give it a try). My next move was a simple change to the usb cable!
You're a saint!!!!

Keep up the good work guys!!!!
