Printing Error

Very happy!
My GUS assembled,But encountered a problem ;)
I will deal with G-code after segmentize,Then G code was introduced into repetier-host host。
I found not in the same plane GUS work!
segmentize error? How I need to solve?

Is homing working now? What have done to calibrate the machine? Have you adjusted the steps/mm of each arm? Have you found many sets of machine coordinates for the effector touching in multiple places along the bed?

It is supposed to look like that.

Repetier Host thinks that [0,0,0] is on the bed. The GUS knows that [0,0,0] is about 130mm above the center of the bed.

Segementize does two things
1. It chops long moves into small pieces (by default, no more than 1mm long)
2. It transforms all the coordinates from cartesian (where z=0 for every point on the bed) to spherical (where the values are the lengths of the arms.

When Repetier host plots the coordinating in the g-code file from segmentize, you see a very distorted image of the object handing in mid air. It really is supposed to look like that.

What Nicholas was getting at was that, if you ran segmentize without going through the calibration steps, you stand an evens chance of slamming your extruder into your bed, which will not be good for your nozzle or your bed.

In my case, I have had my GUS assembled for weeks and I am still iterating on the calibration steps.

Good Luck

Homing problem has been solved, can now print. But do not print on a plane

I use 62/mm steps ,This is not right?

62 steps/mm might be right for a 16x microstep controller.

If the value is wrong by as much as .1 step/mm, the bed will be 13 steps away when you move to where GUS thinks the bed is.

You MUST measure your arms and adjust the values of steps/mm for each arm individually.
You need to be certain that when you tell an arm to move 10mm it really does move 10mm.

Thank you, but I'm not in a plane printing

He seems to be printed on an incline of 45 degree.
