Firmware for geeetech 3D printers

[Mark]

you need to calibrate the X/Y/Z/E steps/mm of your axis, compare the actual moving distance with the target one, and then increase or decrease those values:
#define DEFAULT_AXIS_STEPS_PER_UNIT {78.74, 78.74, 2560, 95}

I have an i3 Prusa. Arduino is asking to slect board type of sanguino. I do not see that board listed. I can't compile my sketch into my Rumba board. I run windows 10 and am trying arduino 1.0.1.

[Mark]

did you set the xorrect rumba board type in the firmware? and select the Mega2560 in the arduino.

Having problems with the I3 pro C (GT2560) fireware.
First I downloaded your latest firmware:
http://www.geeetech.com/forum/download/file.php?id=1555
I had to change this line:
from: #define INVERT_X_DIR false
to: #define INVERT_X_DIR true
Please fix this in your download so other don't have the problem.
I still can't get the heatbed to turn on. It's not a hardware problem. I have already replaced the GT2560 and heatbed. The temp reads correctly and the bed heats when plugged into extruder 2 plug. It must be a firmware problem. What should I try?

[Mark]

the firmware you download is not the latest one, just find the one for your printer here:

"The temp reads correctly and the bed heats when plugged into extruder 2 plug. It must be a firmware problem."

From your link I used this file quoted from the page you linked to:
"5) I3 pro C

I3 pro C (GT2560)
Marlin_GT2560-PI3_Pro_C.zip

Please post the direct link to the firmware to "Geeetech i3 pro C dual extruder 3D printer" this printer ->http://www.geeetech.com/unassembledgeee ... p-927.html

Play around with your axis directions. 1 or -1 on your problem axis. Try doing an invert of true or false in the motor directions. I finally got mine right today.

My heatbed was not working and it turned out to be a PSU problem. One of the 12v outputs was not working. I just moved the wire to an output that was working and the heatbed powered on correctly. PSU check should be added to the troubleshooting list. Since everything else was working it wasn't apparent that I should check that.

Hello,

please, can you check your file and load back when your correctly sentence ? for

Because it has a lot of errors in your code and we don't use our printer 3d with bugs.

Below, the code error with your file MARLIN.(I just dowload in your website and i checking )

Hello,

Please can you check your file for Marlin_GT2560-PI3_Pro_C.zip because when i want, download in my GT2560 your file MARLIN, the software show me a lot of error in the code and i don't use my printer

So can you check your file and load back in your website ?

Thank's
