Getting 'Move out of range' error when doing manual Delta Calibration

Basic Information:

Printer Model: Rebuilt Delta Printer
MCU / Printerboard: SKR MINI E3 V3
klippy.log

This is my first Klipper build, and I’ve been rebuilding a Dreammaker Overlord Pro from the ground up. I’ve been able to get most elements of the build working fine, but when I went to do the Delta Calibration (manual, haven’t been able to mount a probe yet) I got the first point of the probe to work alright, after increasing the negative minimum Z height a good bit to get the print head close enough, but as soon as I hit ‘ACCEPT’ it gives me the error " Move out of range: 0.000 42.750 20.000 [0.000]"
I’m not sure what’s going on here, can anyone give me suggestions of what to check?

The only thing I could think of is that I have some issue with the printer’s build volume, but I’m not sure exactly what.

Also, can someone let me know where in the config you define the Delta’s build volume? The printer I’m building off of had an advertised build volume of 170 mm diameter x 260 mm Z height, but when I put the endstop position at 260 it would always be really far off from the build plate during the manual calibration. Increasing this got it closer, and I was able to get the first point to apply enough force on a shim, but the printer seemed to think it was getting into the negatives, and I had to edit the “minimum_z_position” to be negative for this.

Any help will be much appreciated

Describe your issue:

Your klippy log have following line:

Delta max build radius 35.67mm (moves slowed past 25.79mm and 33.57mm)

So klipper automatically did calculated it.

Your current values for arm_length or delta_radius seems wrong.

Re-read carefully about each parameter.
Linear Delta Kinematics configuration

Why i’m considering them as wrong:
With print radius of 170 your arm have only 206, so if it would go vertical, it can reach only 206-170=+36mm past center point

For example i own fully custom build delta with arm_length=343 and delta_radius=134 this give me 343-134=+200mm past center point

Here is an answer - 170 - it’s diameter - so delta_radius is only half of it.
You should measure it and recalculate it as described in documentation.

The delta_radius was definitely the issue, thank you!
