I don't understand why this is happening

Home:
Height from bed to nozzle 306.5
G91
G1 Z-100 226.5 -
So it's moved 80mm instead of 100mm. I suspect you are using 16-tooth pulleys, in which case your tower steps/mm should be set to 100 instead of 80.
Thanks to Doug for picking this up.
-
That exactly what I was Suspecting the fact the nozzle was stopping 75mm wish short is around 25% short which would confirm the 16/20 tooth hypothesis
-
I have nothing that tells me what the parameters are, but I have changed the numbers from 80 to 100
That looks so much better, thank you!!!!!
I still need to sort out probing the bed. It looks like the nozzle is about 10 or so above the bed, and I get a message for each probe attempt that says that the probe is already triggered. (Which is what I was expecting based on)
M558 P1 H10 F120 T2400 I1
The last time I took out the I1 at the end of that line, the hot end crashed the bed without triggering. I can physically press up on the nozzle and the physical switch will click and change state.

Dropped the I1.
Homeall Great!
Auto Delta Configuration
Stops about 10mm above bed. Nozzle descends to probe, Does not stop. -
Sorry but I can't help there but if you would like to do the cal semi automatically you could change the probe type to P0 run the autodial routine and follow the on screen prompts

Hi
Thanks. I will try that. I think I need to put the I1 back into M558. I suspect I should rewire the end stop for the Z Probe -

Have you tested the Z probe? See https://duet3d.com/wiki/Test_the_Z_probe.

By default, the metal switch tab is pressed against the little red switch button. The button is pushed in. The light on the board is off
When the nozzle contacts the bed, I hear the click and the light comes on and the metal tab along with the little red button switch are released.
The wiring is to the two outside terminals on the switch.
M558 P1 H10 F120 T2400 I1
When it probes, it reports that it is already triggered.
If I remove the I1 from the end of the M558 Line, the message is that the probe was not triggered, and the probe crashes the bed.
Should I move 1 wire to the center pin from the outside pin and would it matter which wire I moved?

You should be using P4 if you are using the E0 Stop connector for your Z probe.
Increase the X, Y and Z numbers in your G1 S1 X305 Y305 Z305 bed.g file to 400+ to keep from having to double tap the home button when the effector is on the build plate and close to the edge.
Don't forget to add M501 to the end of your config.g to use the settings you save in config-override.
-
Use M558 P4 as number40fan says, and remove the I1.
-
Ok
I removed the I1 from the M558. The nozzle drops down to about 10mm above the bed, and moves to all of the expected locations. It does not move down to contact the bed. I get a message for every probe point that was to be used indicating that the Z probe was already triggered.The value reported for the Z probe is 1000
-
Did you try it with the I1? With DWC open, change the I1 setting and reboot. Then while watching the Z Probe reading the in the top right hand corner, see if it sits at 0 when the Z probe is not touched and goes up when touched (with your hand).
-
With the I1 back in, the probe value is 0
If I touch the hot end to trigger the probe, the value changes to 1000
-
With the I1 back in, the probe value is 0
If I touch the hot end to trigger the probe, the value changes to 1000
That is the correct behaviour. What problem (if any) are you having now?
-
Wow!!!
Fantastic!!!!!! Auto Delta Calibration just completed a perfect cycle. Hot end dropped to about 10mm above be, and then gently touched down at 10 specific points, clicked the switch and moved on!!!
Thanks so much for the support and the help.
Now I can try to calibrate the extruder which is either putting out too much filament, or my layer height settings are off, or…....
