Duet 2 Wifi + BLtouch issues on Ender 5 pro

@mitch just out of curiosity, how and where in comparison to your nozzle is your bltouch mounted?
-
@alxndr that is also defined in the config.g I posted. It is in the G31 setting for X and Y offsets.
; Z-Probe M950 S0 C"exp.heater4" ; create servo pin 0 for BLTouch M558 P9 C"zprobe.in+zprobe.mod" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds G31 P500 X-43 Y3 Z2.0431 ; set Z probe trigger value, offset and trigger height M557 X0:180 Y40:195 S40 ; define mesh grid -
@mitch I don't get how we have the same printer and yet we have different values for axis limits.
-
I have a hemera direct drive extruder w/ BLtouch. You have a stock bowden extruder. You just need to go find the limits you have with your BLtouch setup and change the values.
-
If you want to probe 4 points change your M557 from using S40 which is spacing between points to P4 which is probe 4 points and figure out the spacing automatically.
-
@Phaedrux so I did that. But it only probes 3 while saying it can't reach some points.
-
@mitch would you happen to have an example of start and end gcodes that i could look at? im trying to set mine right now. Thanks!
-
@Phaedrux hey again! would you have any suggestions for start and end gcode? this is probably the very last thing i have to do until i can finally print. thanks!

Adjust your M557 grid based on your M208 size and your G31 probe offset.
If it's saying it can't reach a point, it's because it physically can't get the probe there. So move that point further in where the probe can reach.
