I am currently using repetier firmware for my kossel. I have gotten my bed level at X, Y, Z, and Center by adjusting the end stop offsets and modifying the delta radius. Now my problem is that in between the towers is not. So travelling between the Z tower and the Y tower (directly opposite X Tower) the nozzel really drags the paper in between the two, and then on between X and Z towers it is actually not dragging at all. Almost every guide I've seen only mentions calibrating these 4 points to level the bed, but after doing so I'm still getting these other errors, so my question is, what do you have to adjust to get the bed level between the towers?
Also, I have a seperate question reguarding steps per mm and diagonal rod. In getting the X, Y dimenions accurate I was initially going off a guide that told me to change the steps per mm to adjust the size using (current steps * expected size) / (actual size) = new steps per mm. Then I've read other guides that say you should be adjusting the diagonal_rod_length in order to get an accuracy in the X, Y dimensions. So I was wondering, what the difference was between those, and if there is a time to use one over the other? Thanks
