Geeetech

Hi!

I decided to change the config of my Geetech I3 Pro B printer.
I downloaded the correct firmware from the firmware page on this forum, but after i flashed it with the new firmware it couldn't move the axis.

After alot of time spent troubleshooting i was able to use this command:
M92 X30.00
Which changes the steps per axis, which unlocked my x-axis.

This could not be done with the y and z axis, which still dosen't move, the motors just makes a sound and moves super super slowly.

Changing this section in the configuration.h file did nothing:
// default settings

#define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,2560,93} // MXL, Z M8=1.25, MK8
#define DEFAULT_MAX_FEEDRATE {400, 400, 2, 45} // (mm/sec)
#define DEFAULT_MAX_ACCELERATION {5000,5000,50,5000} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for Skeinforge 40+, for older versions raise them a lot.

#define DEFAULT_ACCELERATION 1000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves
#define DEFAULT_RETRACT_ACCELERATION 2000 // X, Y, Z and E max acceleration in mm/s^2 for retracts


I have tried contacting geetech to give me the config, but no answers atm.

Thanks.

Hi,
Don't worry.Maybe you have a wrong firmware?Did you download your firmware from this link:
http://www.geeetech.com/forum/viewtopic ... 20&t=17046 1.What motherboard is your printer?
2.Which Arduino version did you use?
3.And did you upload the firmware successfully?

Hi!

Yes, i downloaded and installed the firmware that you linked correctly.

But i finally after many many hours of troubleshooting that in the configuration.h file EEPROOM was disabled.

Once when i enabled that everything worked as before.

This took me several hours to find because none of my axis was moving.

So all your axes are working now? I'm wondering why the motor won't move without the EEPROM function

Correct, once i enabled EEPROM everything started to work again as normal.
None of the axis was moving, nothing at all.
Very strange, the correct preinstalled firmware is not the same as the downloadable firmware that the support people are sending.

I think it has something to do with the steps_per_axis config. Am i the only one with this problem?

Because when i contacted the support telling them exactly what i had done, that i downloaded the correct firmware and everything but they only responded with the link to the same firmware... As you can see above.
Well hope this thread helps someone who had the same problem as myself.

But i still don't understand why the movement of every axis is related to the EEPROOM function...
