@dc42 Heyyy, so.... the 5v, 3.3v, and vin voltage lights all work accordingly. I had disconnected everything and have the duet floating in mid air to be absolute 100% nothing is somehow shorting it. The diag led flashes on and turns off almost instantly after. I cannot see anything in any of the sys files to be off. I had reset it just in case, reinstalled the firmware through Bossa but to no avail. I can connect to it in S3D and YAT and thats the only way I can control the printer. The only thing I can think off is there somehow being a short in the ethernet port as it gets a bit warmer to the touch (not sure if its intended this way) the CPU reads 35c on my thermometer and the port reads around 28/30 . Sadly it still seems to not work.
Purchased the board of the Duet3d. Can provide any details on DM's of course.

So after getting my Bl touch issues sorted, got my printer running. Calibration tests etc all showed very good results. When booting up my printer earlier today I got onto DWC before going downstairs for a while. Came back to see it was trying to connect as the connection had been lost. Look over and see that the ethernet lights are off as well as my hotend fan. Take it all apart and cannot see any actual damage to anything. It just seems that the ethernet has stopped. I have it plugged in to my pc with my X,Y drivers and seem to be able to move it no problem. How would i go about replacing the board? Having this issue ontop of a dead driver 0 (forcing me to use my e1 drive for X which I had mentioned in my first post) its just a pain in the bottom having this cripled board

Checked the continuity of my wiring. All seems in check with my wiring BUT somehow it doesn't work. I made a new wiring loom just to test it all out and it seems work. Now why on earth the other loom doesn't work is a mystery.
I did also just cut through the 3.3v logic trace just in case which didn't hurt

@Phaedrux
So Ive changed the H value to H5 and it didn't change a thing sadly
Removed the m98 from my homing files
Reduced the P value to 25
Ive wired my bl touch as shown in this
M401 and M402 do deploy the probe but in DWC it still just shows Z-probe as 0
And finally my BL touch version is V2.0 You can see on the image included what it looks like! AFAIK its genuine, purchased it from amazon and others seem to agree its real.

Only thing I havent done is cut the trace for 3.3v but that shouldnt affect it??

Also its a hypercube evolution if that affects anything

Heyo, got myself a second duet board after using a duet wifi for a year I was hooked.

So apart from issues im having with a shoddy X stepper motor (an issue for another day) I cant get my BL Touch to work. When I first setup my Duet wifi 2 I had issues with it not moving to the locations I wanted but that was a simple fix. I stole my Bl touch from my current machine while waiting for another in the post just to setup my firmware. I can get it to retract and deploy using M280 P64 S10 / S90 but it won't actually trigger. When I go to home my axis all is good on the X and Y but once I reach the Z it goes downhill. I clearly triggers as it retracts but doesnt actually stop the axis. It just keeps on going as well as deploying the probe again and again and again. I did try to follow the documentation but I am a bit lost on it? It seems so much easier on a Wifi 2.
What is the solution to this issue

my config.g is
; Z-Probe
M574 Z1 S2 ; set endstops controlled by probe
M558 P9 H2.5 F120 T5000 ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X15 Y0 Z2.5 ; set Z probe trigger value, offset and trigger height
M557 X15:285 Y35:285 S30 ; define mesh grid

homeall.g
; homeall.g
; called to home all axes

G91 ; relative positioning
G1 Z5 F6000 S2 ; lift Z relative to current position
M98 Pdeployprobe.g ; deploy mechanical Z probe
G1 S1 X-305 Y-305 F1800 ; move quickly to X or Y endstop and stop there (first pass)
G1 S1 X-305 ; home X axis
G1 S1 Y-305 ; home Y axis
G1 X5 Y5 F6000 ; go back a few mm
G1 S1 X-305 F360 ; move slowly to X axis endstop once more (second pass)
G1 S1 Y-305 ; then move slowly to Y axis endstop
G90 ; absolute positioning
G1 X10 Y35 F6000 ; go to first bed probe point and home Z
G30 ; home Z by probing the bed

; Uncomment the following lines to lift Z after probing
;G91 ; relative positioning
;G1 S2 Z5 F100 ; lift Z relative to current position
;G90 ; absolute positioning

M98 Pretractprobe.g ; retract mechanical Z probe

Have created retractprobe.g/deployprobe.g with M280 P64 S10/90

Updated to 2.04 both firmware and DWC

Please help,

Thanks in advance
