@cosmowave that worked to slow down the blower thanks!

@OwenD i think i kinda figured it out i changed a few things in your mesh.g, it still acts odd at the end but it works without crashing the probe now. after the mesh it wants to go to the center of the bed, than dock the probe, than center of the bed, than undock the probe, than probe datum z, than dock the probe.

; set Z = 0 to centre of probe area
; echo "Call deployprobe.g macro"
M401 P0 ; This runs macro file deployprobe
G1 X{var.ProbeCenterX- sensors.probes[0].offsets[0]} Y{var.ProbeCenterY- sensors.probes[0].offsets[1]} Z{sensors.probes[0].diveHeight+5} F600
G30
echo "Mesh probing"
M557 X{var.m557MinX,var.m557MaxX} Y{var.m557MinY,var.m557MaxY} P{var.ProbeNumX,var.ProbeNumY} F9000

@OwenD so I had things working well with your help last using a bl touch I switched to a euclid probe and I started having odd issues all I did was add probe undock at the start and dock at the end. When I run a g29 out of program for the default bed mesh it gets the probe moves to bed center pauses than starts to move to the right rear corner well coming up with the bed driving it into the probe giving it a false trigger that going down to the front left corner and starts to bed mesh as it should. The new probe location is center on x from the nozzle and 35mm behind it on y. This seems to be the last bug I need to fix before I can test run a print. I debuged g28, homez, and my auto teach nozzle offset macro, I just need to fix the auto mesh

@owend changing my bed.g to this seems to have helped

@owend I have a Theory to why it’s crashing. My 3 point bed leveling before the new smaller mesh on my 500x500mm bed is just too much of a difference from the outter most points of the bed level to the new inner smaller point bed mesh. I manually moved the three probe points much closer the the center and the mesh looks quite a bit better as well as flatter with less extreams. My z changed quite a bit with this new bed level as well by almost .45mm.

Is there a way to auto ajust the bed level points to be in the same area of the auto bed mesh?

@owend I’m getting some mix results with the bed mesh either works out great or works out horrible with driving my nozzle right into the bed I don’t know is doing a 3 point axis bed level is messing with the bed mesh or the last z offset probe touch

@norder oooo how would I assign additional cooling for PLA?

@norder no that helps thanks I use both super slicer and prusa slicer depending on my needs. The reason for the question is some Prints like pla use cooling and some times need additional cooling so I turn on the towers, but if I run the print over night since I turn them on from the duet control it will run the fans all night until I turn them off in the morning even though the print took a hour ect…

Just one other question is there a timer macro that could be used at the end so when the print finishes run the fan for 5 minutes than turn off?

@chrishamm what is I wanted to tell it to turn on at a certain layer height? Is that possible?

these are my fan configs in config.g

;;; Fans ;;;

i want to know what do i need to add to the slicer end gcode to turn on and off my:

@owend

sorry one more question so far every time the start code hits your lines the hotend and bed turn off during the mesh than back on after. i tryed moving some things around but it still turns off all heaters during the mesh. here is my full start code
