Setting up homepoint?

[jassutassu]

I just got my new printer i3X GT2560

Problem is when I manualy move x+ it goes left and X- goes to right.
Also y + goes to behaind the printer, and - goes to me.
Z axel works just fine.
Are those right directions?

Seems also that the homepoint is missing, pressing home makes it goes all the way over axels. How to set this up?
Been running fimware from this forum for it.

Thanks !

Your axis is going in the wrong direction, you can change it in configuration.h in your firmware:

#define INVERT_X_DIR true
#define INVERT_Y_DIR true
#define INVERT_Z_DIR true
#define INVERT_E0_DIR true
#define INVERT_E1_DIR false
#define INVERT_E2_DIR false

Yeah thanks, thats works fine now.
However my next problem seems that bed.
When I try to calibrate the distance from bed to extruder. In the middle of bed, its 1-2mm distance, and the edges are like 0,2 or something.
Is that bed just bended or is there something to do with that?

You can find a frosted glass about 3mm thick and clamp it to the bed, you'll find it works well with the temperature about 60-70 degrees.

Small objects printing just fine, when Im trying to print abit bigger objects.
Seems that Y motor loses its place. Sounds like its skipping some gear? Then the printing place will be lost, and keeps printing on different place.
No effect if its very tensioned or not.
Motor problem?

I think the voltage of the motor is too low, you can refer to the post here to adjust it:
