Hi winitalia,

please try with this Marlin, I think that the first time you had the new version and we haven't tested it with our configuration.

Thanks.

Regards.

Done.
Now's compiling correctly, but no motor seems to work. Neither x, nor y, nor z.

Hi winitalia,

before moving the motors, do you press the home button? If you press it, please send us a photo of your board and your end stops. We want to know how you have wired the printer.

Regards.

Ok.
We managed to solve the motor problems.
Now everything seems to work fine.
But...
...when we try to print something the filament does not want to stick to the bed while continuously moving the object.
:?
A video can say more then thousand words.

Printer Problem Video

We set the values on Cura exactly like the screenshots on your step-by-step guide.

Can you help us?

Hi winitalia,

to avois this, you have several options:

- Clean the bed really well with industrial acetone.

- Use hairspray to increase the adhesion of the plastic.

- Use kapton tape to transfer better the heat of the bed, you have to clean it very well with acetone.

Regards.

Hi All,

I have the same problem with my X axis and I guess it is the voltage to these *2 motors should be higher?!

Just came across how to measure the voltage on the driver: http://reprap.org/mediawiki/images/0/02 ... ecking.jpg

Hoping for a solution

Hi Ozista,

with which motors have you problems?

Normally, you have to measure in your drivers 0.4V, have you measure them?

Once you measure it, normally, in the Z-Axis (it has two motors) you have to give it more power with the potentiometer.


Thanks.

Regards

Have you try with the DEFAULT_MAX_FEEDRATE ? my stepper motor start making noise but not move and i change to {5, 2, 2, 10} and goes fine. I don't have a cooking hacks machine, but i have ramps.
