Prusa i3 Print part is mirrored Help!!!
November 13, 2014 04:06AM
Hi

I really need help to fix my Prusa i3 printer. The objects are mirrored ( I think is the X axis). The only way I can print normal part is to use Cura and make X mirrored .
Is this hardware hardware or software fault?
Thank you.

it happened also to me when I set up my firmware..

try to change:


#define INVERT_X_DIR true

to


#define INVERT_X_DIR false

watch out because the home position for your x axis will be on the oposite side.
I don't know if it's the best way to solve it, but it's how I did it.

Yes, this is the best way to solve it!

Other workaround is to disconnect the machine from power (VERY IMPORTANT) and to simply put the stepper motor connector in backwards. This way all the motor's movements are reversed smiling smiley

But doing it in the firmware is a way better solution i.m.o. You can also set the direction for the endstops that way so you don't have to change it physically.

Thank you guys. I will try to make the changes and let you know. it's bed time for me now (long day at work) smiling smileyBTW, i'm getting wave edges on print and not straight. Is this because of X axis (i'm not using bearing holder)?

Have you cheched the screws on the pulleys? Maybe they are loose.

Hi,
@ProtoLab3D, I fixed the wave edges on print. forum [forums.reprap.org]
I didn't get the chance to change the motor direction yet. Because i had bigger problem with the printer.
Thank you
