About M109 "Ahead of G29" or "Behind G29" Option Setting #9795

Closed xsuper9988 closed 3 years ago

xsuper9988 commented 3 years ago

Is your feature request related to a problem?

Because "25 points" and "Hot End" take a lot of time

Describe the solution you'd like

when i use 25 points ABL and i didnt use Hot Bed I hope M109 "Behind G29" when i finish ABL Hot end is almost done

when i use ABL and i use Hot Bed and The hot bed may warp then i hope wait for Hot bed finish os i hope M109 "Ahead of G29"

Describe alternatives you've considered

NO

Affected users and/or printers

when anyone dont use hot bed

The G29 command is usually added from the StartUp G-Code in your machine settings. It would be helpful if you would post your startup G-code.

fvrmr commented 3 years ago

Hi @xsuper9988 thank you for your request.

Like @GregValiant mentioned a sharing your start gcode would be helpful.

In the settings guide you can find more information about heating befor the start g-code. https://github.com/Ghostkeeper/SettingsGuide/blob/master/resources/articles/machine_settings/machine_start_gcode.md#heating-before-the-start-g-code

d-schmidt commented 3 years ago

@xsuper9988 you can use variables in your "Start GCODE" and do the heating yourself. Cura doesn't add heating when you already did: grafik

d-schmidt commented 3 years ago

Try also heating the bed in you custom start gcode. This feature is not documented, I think, so you have to try. My Cura honors my custom heating: grafik

GregValiant commented 3 years ago

I'm confused. M104 is set Hot End Temperature and M109 is wait for Hot End to reach Temperature. M140 is set Bed Temp and M190 is Wait for Bed to reach Temperature. So: If the bed is off you want ABL with the Hot End off also ("I hope M109 "Behind G29"") M190 S0 ;bed off G29 ;ABL M109 S240 ;wait for hot end to hit 240

if the bed is on you want ABL with both the bed and hot end completely heated ("i hope M109 "Ahead of G29"") M190 S70 ;wait for bed before continuing M109 S240 ;wait for hot end before continuing G29 ;ABL

Is that the kind of thing you are looking for?

d-schmidt commented 3 years ago

I heat my bed before the ABL and then heat the extruder while ABL. Because the extruder temperature doesn't matter for ABL, it shortens print time and leaving the extruder at high temps without printing for long amounts of time isn't good.

If you don't want the bed to heat you probably still need M190 in the start code to trick cura into not adding heating again. I think adding M140 M190 even if you don't want to heat your bed should work. If they are set to 0 they should be skipped.

M140 S0
M190 S0

YES When not using hot bed I can start ABL and HOT END together This can saves time

You can always just open the gcode file and delete them using a good text editor like notepad++, sublime, atom, any ide

So it put the build plate heating commands still before the start g-code. This is expected because your start g-code contains no settings relating to the build plate temperature, only to the nozzle temperature.

Could you try removing the extra spaces from your setting keys? They do not belong there and might be causing this issue.

@Ghostkeeper you still heat the bed twice. I guess you need to use variables for all 4 temperature settings: grafik works for me. Set the bed to 0 in print quality settings.

Thank you I finally confirmed the real problem

@d-schmidt problem is extra spaces

@fvrmr And then please evaluate this Function (About M109 "Ahead of G29" or "Behind G29" Option Setting)

Thank you very much everyone

Ghostkeeper commented 3 years ago

There are a lot of possible start g-codes, necessary for all of the hundreds of printers on the market. We're not going to provide options to automatically generate all sorts of combinations of them. That's why the start g-code is a free-form text field. So we'll reject this feature request.

Cura currently doesn't even generate the G29 itself; that's all in your start g-code.
