I found the solution "M558 P8 C"^!zprobe.in" R0.4 H5 F300 X0 Y0 Z0" That did it

Thank you Veti,
is good to have someone's else eyes on it and spotting this dumb mistakes, the thermistor is a mistake too. I'll correct them and try again after I upgrade to 2.04RC1, currently I am in 2.03. I'll let you know how it goes. Thank you once more!

I found the solution "M558 P8 C"^!zprobe.in" R0.4 H5 F300 X0 Y0 Z0" That did it

Hi folks,
I updated my delta printer with a Duet WiFi to RRF v3.3 from v2.05, I know a few things changed in the config one of those M558.
I had the piezo working correctly before with M558 P5 I1 R0.4 F300 X0 Y0 Z0.
I changed it to M558 P1 C"zprobe.in" I1 R0.4 H5 F300 X0 Y0 Z0 it does try to probe but I get an "Error: Probe already triggered at start of probing move" I can see under "Z probe" in the dashboard it shows highlighted in red 456 and when I tap the piezo goes down to zero and back up again it does detect the taps.
I have tried changing I1 to I0 in different combinations with P1, 2, 5, and 8 but I can get it to work I still get the same error.
Could you folks guide me on what are the correct settings that I should be using? Thank you all for your help.

Hi T3P3Tony,
l already read both of them, what was weird is that after following instructions setting the Z offset it wouldn't take as I mention I had to Disable Mesh Grid Compensation to make it work and I do not know why, I would have thought it sets correctly every time I run it.

Well I think I figured it out, if I do a "Disable Mesh Grid Compensation" G29 S2 I think it makes it work, I do not understand why that seems to work, I would have thought that Mesh Grid Compensation would have helped not make things break. Could someone please shed some light I am confused.

I am trying to calibrate my Orion Piezo with a Duet WiFi, I am following the instructions here “https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Calibrate_the_Z_probe_trigger_height” for Calibrating the Z probe trigger height however I am unsure what am I doing wrong. After following the instructions I come up with a trigger height of “-0.177 mm” I did entered it in the config.g file do a reboot and when I do a G31 in the console it reports as “G31 Current reading 0, threshold 100, trigger height -0.18, offsets X0.0 Y0.0” all good there. I do an “Auto Delta Calibration” all completes correctly, home the machine and lower the nozzle to the bed to a sheet of paper, I still got 4.04mm to go and the nozzle is already contacting the page snug where I can hardly move it. It does not matter how many times I calibrate with “Auto Delta Calibration” or “Mesh Grid Compensation” still there is too much Z travel, I checked my config-override.g but I do not see a G31 I can only find one in config.g. Could you folks please let me know what am I doing wrong? Thank you!

Found my mistake, it was a syntax mistake looking at the command I realize I entered twice the "S" parameter, the first instance was getting applied duh!

I continue to get this error "Error: Heating fault on heater 1, temperature excursion exceeded 15.0°C" even after PID tuning. I have checked around and it seems the solution should have been to add SX.XX to M307 however I have gone through multiple tries from S0.8 down to S0.01 and repeated "M303 H1 S220" multiple times, also I have replaced the 12V heater once but still overshoots over 15.0° and goes into a fault, after the last M303 that I did I got this results ...

Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 658C.
Auto tune heater 1 completed in 211 sec
Use M307 H1 to see the result, or M500 to save the result in config-override.g
Auto tune phase 3, peak temperature was 251.0
Auto tune phase 2, heater off
Auto tune phase 1, heater on
M303 H1 S220
Auto tuning heater 1 using target temperature 220.0°C and PWM 1.00 - do not leave printer unattended

The line in the config-override.g and config G is M307 H1 A633.7 C148.0 D12.4 S1.00 V12.4 B0 SX.XX (where the X are different combination of values). Could you guys please shed some light on what is wrong? Thank you!

Hi Veti,
It is working now! I do not know exactly what did it since I did everything you suggested, removed first line, added the space and upgraded the FW to 2.04RC1.
Anyhow I thank you for your help

Thank you Veti,
is good to have someone's else eyes on it and spotting this dumb mistakes, the thermistor is a mistake too. I'll correct them and try again after I upgrade to 2.04RC1, currently I am in 2.03. I'll let you know how it goes. Thank you once more!

I apologize for the long post in advance. I am having issues with my new delta build with IR probe/duet Wi-Fi, when I do a delta calibration with 6 peripheral points, 3 halfway points and 6 calibration factors my settings change but not to the correct numbers, case in point the "delta radius" that I have setup to 100mm in M665 after a delta calibration is changed to 128.922mm, if I try to do another delta calibration the effector hits the belts by the towers since is going out of the 100mm radius. Also the homed height in M665 is set at H354.58 that is correct I checked it from Z0 to triggering the end stops at the top however after a delta calibration it changes it to H365.82
Also it varies a lot on where the probe triggers hence I have to keep the height at about 15-20mm any lower and the probe triggers before it starts probing.
If I try to do a mesh calibration the effector retracts from the bed about 50mm and starts to probe from that height even though I have the setting at H15-20mm in M558. Furthermore for some reason the probe triggers from point to point with a lot of height variance, in some points it does not even trigger.
The times that I have been able to get a Heightmap it looks really weird like a cone The edges go really high up past the bed and the point very low under the bed or as of lately the map is showing very low under the bed to the point that I have to zoom out considerably to see it, this happen after it started moving far high from the bed to do the mesh calibration.
I checked the mechanics of the delta and the rods are the same size no play on the magnetic ball joints, towers are squared, I see a little bit of difference in the height of the end switches in the delta calibration but not that much. I have re-done the RepRapFirmware Configuration Tool multiple times but still if is not one thing is another, I am lost and throwing the towel! could you fine gentleman point me in the right direction on what to check? Or what I am doing wrong? I been at it for days and I can’t figure it out time to get help, my configuration files are below. Thank you!
