[jean-luc]

i bought a printer i3pro c with 2 extruders. the 3 axes x, y z works correctly in manual or auto, the extrudeur 0 works in manual in software repetier but not in job ; the extruder 1 don't works ( when the temperature is ok)
when i make a job, since pc not sdcard, the printer move correctly on three axes but not extruder, all the temperatures are ok (bed and extruder)
I change driver motor z and extruder1 to see is driver motor extruder1 is out but no axe z works correctly with driver motor exrt 1.
Please help
thank you

Thank you for your response
but as i said , i change driver motor and it is ok (the motor axe works with extruder driver motor)
In manual mode, the extruder motor works normaly, it doesn't work only in job.
please, can you send me a firmware update (mainboard gt2560) ?

Thank you very much.
I install firmware and all runs ok. I don't test the second extruder but i suppose it's right.
Last problem : the pla don't catch on glass ... (bed is 90°c extruder 195°c), have you some help for me ?
On lcd, it's not possible to set diameter to 1.75 mm, the lower is 2.5 mm. i don't know if it's important or not.
Thank you for your help

hi,you could attach some glue on the hot bed.and the best distance from nozzle to glass is an A4 paper.hope these will help you.

what was the fix for this my extruder drive the wrong direction if push retract it extrudes if i click extrude it retracts

Hi, you should change the corresponding motor direction in the configuration.h tab in your firmware and upload it:

#define INVERT_X_DIR true // for Mendel set to false, for Orca setto true
#define INVERT_Y_DIR false // for Mendel set to true, for Orca set tofalse
#define INVERT_Z_DIR true // for Mendel set to false, for Orca setto true
#define INVERT_E0_DIR false // for direct drive extruder v9 set to true,for geared extruder set to false
#define INVERT_E1_DIR false // for direct drive extruder v9 set to true,for geared extruder set to false
#define INVERT_E2_DIR false // for direct drive extruder v9 set to true,for geared extruder set to false
#define INVERT_E3_DIR false // for direct drive extruder v9 set to true,for geared extruder set to false

Hi Mark this did not work now my steppers on the x and z post drive the wrong direction when i try to home it

[Mark]

Did you change the X and Z axis direction? I mean just change the extruder direction and upload it, not all of them.
And if not, you can change the X and Z axis direction to see if it works.
