Run bed levelling wizard issue

[gwenaelfr 0]

Hi,

I need help... after a displacement, our Ultimaker doesn't work well anymore. Indeed, when I launch the Run bed levelling wizard process under Cura, the head won't move in each corner : the head is poorly moving or the head moves diagonally (the 2 stepper motors work together ...)

I've tried several things but nothing works...

- Grease the axles

- Repeat the parallelism of axes

- Tighten the belts

- Try different firmwares

- Check the jumpers

With best regards,

Gwenael

Skip the wizards (hit cancel) in cura.

Click on "prepare icon" which slices the robot (you must do this to get to the next step).

Click on the "print" icon. This will open a new window.

In the print window, go to the tab that controls movement.

Move the X servo alone. Move the Y servo alone. Only move 10mm at a time. Move the Z servo alone. Try to isolate the problem.

Did you check all 5 set screws on each axis? The x axis belts have 5 setscrews (not 4!). Make sure all 5 are very very tight.

Post more details.

Thanks for your reply, i've already tried to move each axe alone and it seems to be ok.

I'll check the screws when I am at the lab.

In fact, the head doesn't abut the corners in each step of the " Run bed levelling wizard" process.

I've never tried the cura bed leveling wizard so I'm not sure exactly what it does.

I'm not sure if the head goes completely in the corners or just near the 4 corners.

"abut" means next to, right?

Yes, it means that the head should touch each corner.. But it doesn't...

Furthermore, during a few seconds, the 2 motors are working instead of only 1.

so i just purchased the anet a3 and i had a successful print once from the stick that comes with the device. Now it seems to be printing about an inch to 2 inches at times from the base. How do i fix this problem?
