Hi,

I finished my 3d printer a few days ago, it is a prusa i3 clone, with a gt2560 rev A board and a atmega2560 chip.

When I move it when pronterface it seems to move correctly in each axis, but when I try to print, the prints looks stretched and a little deformed, I added some photos of the printer and the actual 3d model.

I am a little lost so any kind of help will be greatly appreciated.

Thank you all! :slight_smile:

Hi,

first of all check with a ruler that the movement with pronterface is correct, if it’s ok then check your acceleration/jerk/print speed, maybe you are loosing steps.

Also check (if possible, I don’t know this kind of printer) if stepper drivers are setted with proper current, if it is too low motors will lose steps, if the current is too high motors/drivers will heat up a lot.

If the movement with printerface is wrong, you need to calibrate your step/mm

Check whether the speed of the 3D printer is appropriate or not. Also, check the acceleration and jerk of the equipment which causes the 3D printer to lose steps. Also, if stepper drivers are not provided proper current, this too would cause the 3D printed object to be stretched and deformed.

Thank you, I will check that!

Thanks for your answer! I will do those checks!

Do you know how to check the current from the stepper drivers?
