It is alive. Although there seem to be some skewing of the z axis. I'm not sure if it is rounding/overflow errors in the firmware or I'm losing steps, our if I have a pulley slipping.

I printed a one cm cube which came out noticeably skewed and about one mm to short. I thought it appeared that it was leaning towards one arm so I made a six pointed star and printed that. Long before the print finished it was obvious which arm is different. It looks to me like arm number one is somehow shorter than the other two arms. Now I need to figure out what to do about it.

i finally got back to working on the gus. I got your version of marlin working . It works very well . Now I have a issue of calibration.

How do you fine tune the calibration? I am getting a dome like movement with one corner of the dome pushed up.

From my experience on kossels it is usually a diagonal rod error which causes this. On the gus which variables can correct it?

thanks
