So,basically,this is what happened,that thing actually stick to the board but i remove it,this is the shape of the CROCODILE but is not!!! Please really help me,i m quite a mess here coz i really zero knowledge bout it.
I also try to learn how to calibrate the x y and z axis but seriously,i don't get it how to do it.Then,i try also to learn from other forum but quite hard 4 me to understand it.
Im so sorry for my poor language in English..
From the picture, here is my opinion.
First you need to get your bed level. Right now i see that you're printing directly on top of PCB with kapton tape on it. Well this is not a problem, but PCB is not flat for printing surface. Because of that you might accidentally dig your PCB with your nozzle and damage it. In my opinion you might want to put glass on top of your PCB heatbed and kapton over it. Better to be safe. A spring bed platform might help to level the bed and you dont have to use big clip. Just small clip to clip your PCB and the glass.
Secondly you might need to calibrate your stepper motor, so it move the distance equal to the amount of value you click on the host. I find that this
Calibrationvideo really helpful. It gives the idea how to measure, calculate step/mm and keying in the firmware. You might want to have a look. The method is the same for sprinter or marlin firmware. You just have to key in the calculate value in the firmware.
Cheers.
