Missing fine tune option #define DELTA_DIAGONAL_ROD_TRIM_TOWER
-
see http://reprap.org/wiki/Gcodes#M579:_Scale_Cartesian_axes this will do what you want
-
thx for the Link..so i can insert that manually in the config.g? And does it matter that that is for cartesian axes?
-
How did the marlin trim tower command work? If it was andgles between the towers then look at the X, Y, Z switches to M665:

Tony I think it allowed for different length arms on the 3 towers but I could be wrong
-
yes..in marlin you can finetune the arm lengh.
here i found only a trim for arm angle
-
We don't provide individual arm length trimming because getting all the rod lengths the same is one of the easier things to get right on a Delta printer. If your cube dimensions are wrong, it is almost certainly not because the rod lengths are equal within each pair but different between pairs.
You can adjust the scaling of all axes using the M579 command.
The fact that your Z height is too low suggests that your belts are slightly under 2mm pitch or they are very loose.

Hmm..my Z-Height is ok…guess you didnt look at the calibrate STL...its to see misanglement of the XYZ towers...not acalibration cube...so nothing to do with the height. just the XYZ tower
-
Tried it today with the M579 command..hmm doesnt work..its a calibration circle that was a small oval after that..so that command only works in cartesian but not delta printers

I assure you it works on ALL types of printer.

so.. i made that calibration circle..and used this google sheet https://docs.google.com/spreadsheets/d/1HcnZ0aDC2wujHhPHVeYFcPekEpY6Y4wLSMfCxJ18e1o/edit#gid=1292102991 assumed lenght is 60mm
had on X 59,86 Y 59.39 and Z 59.41
had a R 99.275 and Rodlenght 212.782after that print i changes Rodlenght to 211.727
and used M579 X0.725 Y-0.386 Z-0.339
saved with M500 and start to print another circle
Stopped it after first layer because it printed a oval with about 4x6cmchanging the diagonal rod only affects scale in all directions..so the M579 made a oval from a circle.. where did i make the mistake?
