Hello guys, put together a Prusa Mendel and my first impressions are stretched, as if they were pulled. Another detail is that the table Y command command to move 50mm it advances twice. What could it be?

Already checked several times and it seems all right, I'll try to erase all settings and do it again, there's something else it could be?

Most of the commercial boards use stepper motor controllers. A lot of them have microstepping control inputs, possibly your microstepping hard wired control inputs to the chips have a PCB fault ? i.e. 1/16 instead of 1/32 on one of your boards ?

Yes. Check your micro stepping config. You don't say what controller board you are using. On the RAMPS, there are jumpers beneath each stepper driver. Three need to be installed to have 1/16 micro stepping. If your jumpers are wrong, it could very easily cause your axis movements to be off by a factor of two.
