I3 pro C - Speed problem

[lezabour]

Hi,

I'm having the I3 Pro C, and i have a problem with the speed of my printer.

I'm using Host Repetier & Slicer to configure my prints depending on my needs.

But no matter what i do the printing speed is really slow. In fact, even if i change the speed, for example from 50mm/s to 100mm/sec, i see not change, it"s slow.
I have to use the speeder (x2) to manually speed the print.

I don't have EEPROM defined, so no eeprom.
Also, 2 strange things:
*Even if i make change in Slicer about the speed, i can see in the bottom of GCODE that they are not taken / used (still old values).
* The skirt and brim i use are printed in a good speed, it"s only when layer 2 begin that the slow begin.

I have tryed to change my Slicer version, uninstall, reinstall, nothing change, still same effect.

Don't know what to do...

Any advice please??;)

thanks
