Now I’m starting to print some parts that need to be as accurate dimensionally as possible, I’ve decided to try calibrating the steps for each axis for the first time.
I’ve been taking measurements from each side of both the x and y axis’ and they don’t match. For instance I set the steps at one side of the printer moving the x or y in one direction and it’s perfect, I then go to the other side of the printer moving it the opposite way and it’s some way off. What I’ve done for now is set the steps at halfway between the calculation for either side and, although neither direction is moving to a hundredth of a milimetre accuracy, it’s at least moving the same distance each way, but a 100mm movement isn’t quite exactly 100mm.
Is this the correct way to do it?
The z axis I calibrated using a 10mm movement and my dial gauge, and that seems to be absolutely spot on.
Another question is, is there a way to raise/lower either end of the y axis? When fine tuning the height of each side of the x axis, ive found the the aluminium plate is actually sitting 0.5mm higher at the back end, which could go some way to explaining the 0.1mm dip I have right across the centre of the bed due to twisting. Or is this normal?
Thanks in advance.
