Start / Stop S3D SCRIPT / G-CODE

Re: [S3D users](how do you setup for Duet?)

What and how do users use S3D for the starting script and ending script? Without it the Z-Probe won't work and take into account the mesh bed. Any help / advice is greatly appreciated.

@noblebran

Well for starters in the places in S3D for user code I have

M98 "print_begin.g"

and

M98 "print_end.g"

All the actual code for start/stop is in those two files on the Duet.

Both of these files include calls to macros which I am going to omit for now but you should be able to understand what is going on.

Here is print_begin.g:

; S3D inserts the following before the call to this file
;G90				; absolute XYZ moves
;M83				; relative E   moves
;M106 S0			; fan on to 0 (correct way to do fan off)
;M140 S60			; set bed      temp but don't wait
;M104 S190 T0			; set extruder temp but don't wait
;M98 P"print_begin.g"           ; invokes this file

; select tool and configure based on filament selected

T0				; select tool 0 so extruder commands below will work
M703				; configure selected filament (sets bed/extruder temps, extrusion multiplier)

; check for selected filament

if move.extruders[0].filament = ""
  M291 R"No Filament Selected" P"Cannot Continue" S2 T0
  abort

; check bed heater active temp setting

if heat.heaters[0].active = 0 
  M291 R"Bed Heater Active Temp = 0" P"Cannot Continue" S2 T0
  abort

; check extruder heater active temp setting

if heat.heaters[1].active = 0 
  M291 R"Extruder Heater Active Temp = 0" P"Cannot Continue" S2 T0
  abort

; check if homed - allows homing (OK button) or canceling (CLOSE button)

if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed
  M291 R"Printer has not been homed" P"Home and Continue?" S3 T0

@fcwilt Thank you very much!

@fcwilt I will fully admit I can't follow it. My script for my TLM pre-duet was a few lines. I am lost on how to get it so it doesn't a single probe to get the right height and get up axis.

@fcwilt I am lost on how to get it so it doesn't a single probe to get the right height and get up axis.

I'm sorry but I don't understand the question.

If you are asking about setting the Z=0 datum that happens in the "mesh_comp_map_load.g".

One of the things that you always do before loading the height map is setting the Z=0 datum.

I have it in that file to be sure the height map is loaded correctly.

Here is a simplified version of that file:

M98 P"probe_set_z.g"; set Z=0 Datum

G29 S1              ; load existing height map

M376 H0             ; set bed compensation taper (0 = no taper)

noblebran

@fcwilt said in Start / Stop S3D SCRIPT / G-CODE:

M98 P"probe_set_z.g"; set Z=0 Datum G29 S1 ; load existing height map M376 H0 ; set bed compensation taper (0 = no taper)

I must be really ignorant... I don' have a "mesh_comp_map_load.g"

I must be really ignorant... I don' have a "mesh_comp_map_load.g"

Where you see M98 P"...." that M98 command is executing a file that I created to perform a specific task.

Whenever I have a hunk of code I need to execute from more than one location I place that code in a separate file that I can invoke as needed with M98. That way I don't have any duplicate code appearing in multiple locations.

The common files you are likely to see are:

config.g
homeall.g
homex.g
homey.g
homez.g
bed.g
mesh.g

In addition to these I have 27 other files of my own creation that perform specific tasks.

@fcwilt Okay, thank you for the explanation my friend.

Glad to help.

Do not hesitate to ask any questions you may have - that's how we all learn.

@fcwilt I have no clue or have a start of where I need to go, but am not close to you....

Well let's back up a bit.

What is it you want to do but don't know how to do?

I and others here can provide simple step by step code/instructions to do anything that needs to happen at the start of a print or the end of a print.

Frederick

noblebran

@fcwilt Right now I don't have any code (except old Little Monster Smoothieware code) and I went to print something and the z-probe didn't extend and the height went to low, I did the offset and have done the work to get it all set up, but don't know how to start it and how to end the code. This is all new to me, and it was unexpected. The MKS Base card burnt out so I went with the Duet and have not had the time to do my research like I always like to do. I just don't want to break something in the process.

fcwilt

@noblebran

Have you created the basic files I mentioned and have you installed them on the Duet?

config.g
homeall.g
homex.g
homey.g
homez.g

Frederick

noblebran

@fcwilt Sorry I was in bed and working now. I have done all (not to say they are right or not).

OK lets check those files.

using the </> tag post copy&paste the contents of each file in a separate tag.

The </> tag creates a scrollable region and makes viewing code easy.
