Right way for starting script?
-
There is a gcode that commands a heater or heated bed (different gcodes) to heat and WAIT for temperature. I think you want to use this one.
M190 I think, look on the wiki.

Hi bot
Yeah I figured it out, but now when I start a print with that commands: M190 S50 and M109 S150 for heating it up before probing the bed, the temperature dont rise to the temp for printing (240 PET-G) and as an effect of that the extruder dont extrude anything. I.e. the print starts but it stays on the "Start script" temperatures and dont use the print files temperatures… Dont know what to do... -

You need to do this before M109 otherwise it won't know which heater to heat. If you only have one tool, try putting T0 before M109.

If you use own heating commands in the scripts of S3D then you have to take care of all heating because then S3D does not insert its own heating commands.
So you have to insert the command to heat to print temperature after probing too.
Like M109 S[extruder0_temperature]… -
Hi deckingman & Alex9779
And thanks for reply!
deckingman, the right extruder (T0) heats up ok (as specified in the starting script) to 150c, but when starting to print the object it remains on 150c not 240c (as in the printing-file).
Alex9779, first I tried with S3D but it was a lot of strange behaviour so I used Slic3r, all went well, but as said above, it remains on the start script temp not the object print file temp… I dont want to be forced to adjust the printing temperature in the starting script all the time... -
You do not have to if you use variables as I wrote. The variable I wrote in there is S3D syntax. Slic3r has its own. Also Slic3r does remove its own heating commands if you use at least one in your script.
It was not meant that you insert an actual temperature value there… -
Look here for what is possible in starting scripts for S3D: https://forum.simplify3d.com/viewtopic.php?f=8&t=1959

Ahhh, great link! Really like to work with S3D instead of Slic3r
Thanks Alex9779 , will do some more reading then… again... -
Use the forum post listing all the tips of the day posts. There is one for every tab explaining most of the settings. Some are missing because they have been made with an older version…

@Alex9779 After reading the link you posted I dont quite understand how to make S3D first heat up bed and extruder (using the starting script temperature), then do the probing of the bed, and then take the temperatures from the "printing object" file and start printing the object.
What would the gcode look if I liked to heat up bed and extruder to 50 (bed) & 150 (extruder) do the probing and then start printing with the bed to (60) and extruder to (240) and use the temperatures from the slicer settings (S3D)? If its possible?
Sorry but dont understand using varible?! -
I have found that S3D actually does the start script after the heating cycle and mine has just G32 in the script so when I run a print the bed heats then the hotend then my start script then the rest of the print is executed!

Hi Doug
That´s interesting!! I am not at my printer until tomorrow so have to test that then. But do you have some homing cycle first (in the start script)? Before the G32.. I dont want my extruder, with printing distance to the bed, heating up to 240c and then start printing.. -

M109 S150
G32
M190 S[bed0_temperature]
M109 S[extruder0_temperature] -
Okey, thanks a lot!
With this I specify the printing temp for the "printing file" witch overrides the settings in the slicer?! -
I don't understand the question, sorry. With this you start with heating. Then the bed is probed. When that's finished the head stay at the last probe position and the bed is heated to the temp you set in the temperature tab. Then the same happens for the extruder.
If you want to do the final heating somewhere else insert a G1 command after G32. -
Ok sorry for being unclear.
When you say "temperature tab" do you mean the settings in S3D? -
Yes that's the whole point of using variables in the script. That way you don't have to change the script every time. It takes the values for the specified heater on layer 1. Each heater has an assigned number normally starting with 0 also on the temp tab. That is the number in the variable…

I dont want my extruder, with printing distance to the bed, heating up to 240c and then start printing..My bed.g file has the home in it and then the autocal routines so it is all in the macro.
I have various settings in my S3D Profile for different temps and materials which negates the need to have the temps in the start script I slice using the profile settings I want it waits till first layer temps are reached then runs my Start script and the G32 calls Bed.g macro.

That's right but if you want to move to a specific position before heating like an ooze bucket as I used to have then you can move in the script but S3D does the heating always before your script is executed.
Using those variables disables the automatic heating and you can place it yourself where you want in the startup procedure and do a move first or leveling before heating to the final print temperature…
