Hi!! I'm new using the 3D Printer Geeetech I3 Pro B and I want to know if someone have a full description of calibration steps for this printer. I level the bed with the paper method but there are other things like "Extruder calibration in the firmware with the correct steps per mm of filament", that I don't know how to do, and furthermore how can i know if Belts are taut enough?, the movement of the motors seems correctly, but I don't know if, for little movements and more precision, the belts are taut enough.
I print some simple structures and I have problems with the first layer, the material deposited its not enough, the others layers don't have that problem.
Please help me thank you!
