Have you also checked your config-override,.g ?

Ok, let's work on improving your BLtouch performance.

M558 P9 C"^zprobe.in" H5 F240 T12000

Let's try changing that to this

M558 P9 C"^zprobe.in" H4 F120 T6000 R0.5 A10

It may take slightly longer to perform the G29 but the results should be more accurate.

You should also go through this again and remeasure your trigger height and XY offsets for G31.

@tmeryhew Then you are good to go.

precision piezo is probably the best I've tried, just very stressful... building a 3d printer is already stressful per se, so at the end I decided to just use a high precision switch (the head catches it with magnets). Very happy with it.

Try 500Hz for the fans. That's the default. Valid values go up beyond 30000, so you'll be fine.

For the motors, the ideal current is ~60 to 85% of the rated current for the motor.

So guess what... one of the pins was unseated at the board! Hidden by a wire label.... 🙄

maybe https://duet3d.dozuki.com/Wiki/Connecting_endstop_switches can shed some light on it?

Hi,

Where the extruder ends up depends on the code executed.

The command to move to the end stop leaves that axis, say X, at the location of the end stop, which is typically at or near the min or max limit of the X axis.

On my machine the range of the X axis is -150 to +150, the Y axis from -100 to + 100, the Z axis from 0 to +350.

The X end stop sensor is at the -150 end, the Y end stop sensor is at the +100 end and the Z end stop sensor is at the 0 end.

So if I did nothing but execute the commands to move to the end stops the extruder would end up at -150,+100,0.

However I like to have it end up at 0,0,0 so I have additional "normal" move commands to achieve this.
