@Phaedrux i User the probe as endstop.

Is this Configuration correct? :

; Axis Limits
M208 X0 Y0 Z0 S1 ; set axis minima
M208 X300 Y300 Z250 S0 ; set axis maxima

; Endstops
M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop
M574 Z1 S2 ; configure Z-probe endstop for low end on Z

; Z-Probe
M558 P5 C"^!zprobe.in" H5 F300 T15000 ; set Z probe type to switch and the dive height + speeds
G31 X0 Y0 Z-0.05 P250 ; set Z probe trigger value, offset and trigger height
M557 X5:300 Y5:300 S20 ; define mesh grid

Phaedrux

That looks fine, but you must be using G30 in your homeall.g. Also make sure you do NOT have G29 S1 in your config.g

Phaedrux

That looks correct. Now just make sure you have homed the z axis with G28 before creating a heightmap with G29 and the datum error message should go away.

@Phaedrux @arhi @engikeneer

So .. everything works now and it prints well. Thank you all. Now my last question, as I am new to the RRF. How do I start a print now so that a macro is run, the orion tests the bed and then it prints? I don't know which one. g that's coming. or does it have to be in the slicer start g code? if so, how can I tell that he should use a macro?

I'm not really sure what you're asking.

But usually the slicer start gcode would contain at least a T0 to select the first tool, G28 to home all axis, and a G29 S1 to load the mesh. The slicer would also add the bed and hotend temps.

If you wanted to add something to run before any of that, you can add those commands to start.g in the /sys folder which gets run automatically before the sliced gcode file.

@Phaedrux

i try to explain

i want to add,heat to bed and hotend to X celsius(shpuld be print temp), do a makro, prob the bed, start the print.

the printer should do this one ervery print. where i have to add this commands?

Phaedrux

The slicer should be adding the temp commands that you set in the slicer settings.

arhi

@chop here is how I do it.

in slicer put this:

for start script:

M98 P"print_start.g"

for ending script:

M104 S0 ; turn off extruder
M140 S0 ; turn off bed
M106 S0 ; turn off fan
M98 P"print_stop.g"

then make "print_start.g" and "print_stop.g" scripts to put whatever you want in them... for e.g. I have

print_start.g

; no volumetric extrusion
M200 D0

; relative extruder distance
M83

; do not home if already homed
if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed
  G28

; do the wipe 
M98 P"wipe.g"

; use MESH compensation
G29S1

; all currents to 100%
M913 X100 Y100 Z100 

; load default jerk, speed and acceleration values
M98 P"cfg_jerkspeedaccel.g"

; reset baby steps
M290 R0 S0

; reset speed overrides
M221 S100
M220 S100 

; Dynamic Acceleration Adjustment
; M593 Fxxx

; Pressure Advance
; M572 D0 S0.042
M572 D0 S0.03

;M118P0S"MESSAGE: PRINT STARTED"

and my print_stop.g

M104 S0 ; turn off extruder
M140 S0 ; turn off bed
M106 S0 ; turn off fan

M913 X20 Y20 Z25
G91
G0Z10
G90
M913 X100 Y100 Z100

M98 P"wipe.g"

;M118P0S"MESSAGE: PRINT FINISHED"

now those are mine, you adapt to what you want start/stop to do

arhi

note that slicer will heat up the bed and the nozzle before it executes the "start script"

If you want to get some macro commands in even before any of the slicer gcode starts you can use the start.g macro in the /sys folder. It will get executed at the start of a print before anything else.

This can be handy if you want to take conplete control the preheat and homing of the printer before the slicer takes over. With this you can basically have nothing in the slicer start gcode, which makes it easy to use multiple slicers and keep their start gcode changed in only one place.

Any commands you need to be executed after reaching the slicers set temps can be put into a separate macro and called with M98 in the slicer start gcode section.

You can do the same with the slicer end gcode if you simply use M0 in the slicer, since M0 calls stop.g on the Duet. So your end gcode can be customized in stop.g and used on all slicers.

@arhi ah !! Thats what im looking for. Thank you mate.

Would you pls show me your wipe. G. Thats exactley what im trying. Servo deploys brush nozzle Drives oder the brush to clean .

arhi

@chop here's my wipe.g but is machine specific, you will want to make your own

if !move.axes[0].homed || !move.axes[1].homed 
  echo "X and Y axes not homed, aborting the wipe"
  M99

if state.currentTool < 0
  echo "No tool loaded, aborting the wipe"
  M99

if heat.heaters[tools[state.currentTool].heaters[0]].current < 200
  echo "Extruder too cold, no point wiping, aborting the wipe"
  M99

; Drop all motor currents down
M400
