(meanwhile the directdrive got stuck after 2h of printing... motor is burning hot damn... not sure if I'm already regreting this upgrade)
No, you can't
Did you lower the voltage to 0.6V ? If yes (and it seems that some users have the issue and some not):
- what material do you print ? with cover or not ? bed temperature ?
you need to cool it if it's not good with PLA without the cover... heatsink or heatsink + fan (see firesped design on page 32 of this topic)
i had to do that on my frist N2+ but not for the moment on my N2 (that print a 250% scaled celtic skulll during 80h with colorfabb PLA)
I think on the original conf the big metal support parts acts as an heatsink... so i think it's a good thing to cool the motor and in all case (i will do on my N2 soon) BUT i will loose 3/4 cm on Y direction (coorect it in the software to prevent from uploading a file that will hurt the printer and don't exceed 270mm with the tool menu
