Problem on the value of Z delta print

editux

Good Morning
I have the following problem that I need help solving.
I have a delta printer and I am configuring the duet2 .
With the value of X0 Y0 Z40 or any other value of Z, when I move with for example G1 X-50 Y-50 OR G0 X-50 Y50. value of Z goes down about 5 mm.
I attach my config.g file.

Thank you for your attention.

@editux said in Problem on the value of Z delta print:

With the value of X0 Y0 Z40 or any other value of Z, when I move with for example G1 X-50 Y-50 OR G0 X-50 Y50. value of Z goes down about 5 mm.

Where are you seeing these values?

With a delta, the tower positions all need to move to give XY motion.

How are you commanding movement?

Can you make a video showing what you're seeing?

@Phaedrux These values are entered manually in the console.
The behavior on the model printout is similar.
I attach a video for better perception.
1st phase position X0 Y0 Z40 command after G28
G0/G1 Z40
I use a 40mm profile piece as a comparator.
2nd phase command G0 X-75 Y-75
I place the comparator and verify that the nozzle descended about 5mm.
the same is verified if the command is G0 X-75 Y-75 Z40.
3rd command G0 X0 Y0 and returns to position Z40

I hope I have been clear in my presentation.

How can I make the video available +- 60Mb mpg4

@editux That is because your delta parameters are not perfectly correct.

How did you set them?

Using autocalibration? If so, how many factors did you use in your autocalibration?
By measuring?

@editux as @alankilian says. You need to calibrate your delta printer. See https://docs.duet3d.com/en/User_manual/Tuning/Delta_calibration.

@alankilian Problem solved.
I had indeed calibrated the printer with factor 6. But I hadn't passed the values of M665 and M666 into config.g

Thanks for the tip.
