Layer disalignement at very low speed. Firmware update issues.
My printer has been giving me porblems since I first got it with layers disalignement, kind of sorted it by slowering the print at 20mm/s max speed, but it is taking ages to do anything. I've seen that the people prints at 50 or even 80.
I've realized there is a latest software version wich I tried to install but it isn't doing it automatically as a saw some people was doing it (only install in the SD card and start the printer) is there a specific way do do this update?
Also some people adjusts the stepper motors voltage in other printers, is it necessary in this board and with marlin?
I really need some help!!
