Feature request : TIMER to delay printing

[xaho 3]

Hi,

Is there somebody able to add this function in the UM2 software :

A simple TIMER to delay the printing of few hours like some washing-machines, to print peacefully during night after everybody left the office or sleep at home.

Script like :

select PRINT

select Gcode file

select NOW or TIMER

NOW: start printing

TIMER: set time by 30min steps up to 8hrs (with wheel button)

select PRINT when set

 

This is my dream to avoid Arduino and Octoprint

Thanks a lot !

Sounds great - maybe you should also put this as a feature request directly @ github - also for the UMO Marlin FW... :-)

I don't know the answer but this is what I googled:

http://reprap.org/wiki/G-code#G4:_Dwell

Maybe adding that pauses your printer for a specified time. I guess you would like to write a pluging that generates the dwell time in the start code so it waits. Make sure that the hotend does not heatup during the dwell time, you don't want to have a warm hotend for a long time.

Do you know what would be the highest selectable value for that command?

If you need to wait for several hours, you could probably just queue up multiple G4 commands...

Using pronterface you can easily test the command's behavior.

Hey guys you are talking chinese to me ! I'm not at all a developper

What is a Dwell ?

How do you write a plugin ?

How do you queue up ? what is the command G4 ?

Pronterface ?

Ouch !

Github: I don't get how this blog works and is for ?

ok, another attempt: you could use a (mechanical) timer for powering (like the timers used to controll a lamp to switch it on/off on a certain time) the UM at a defined time and switch it of also on a defined time.

With a slight modification of your gcode name it should be possible to automatically start the print on power on but I can´t find the post describing this right now...

Anyone here remember the gcode config??

 

[drayson 75]

found it !!

but in another forum: http://forums.reprap.org/read.php?146,187253

[...] I think if it finds a file on the SD card called auto0.g it will run it automatically. Once it has done that it will look for auto1.g, etc. I have never tried it. [...]

So change the name of the file you´d like to start to auto0.g and power the UM, it should execute it...

Disclaimer :-) I have not tried this - so no guarantee...

Drayson you are a genius !

Brilliant idea, actually I use already a WEMO remote plug (Belkin) to switch it off when print is done + Dlink webcam.

I go look at this forum asap

Thanks !

I was about to try this when I wanted to start the printer when I was already asleep. But then I finished all the parts in time so didn't look into it.

Dwell(G4) should works, either with multiple or just 1.

auto01.g should also work if you have a remote power switch

Both interesting, let us know!

 

[xaho 3]

I've just tried "auto01.g" but the printer starts print directly in the corner without warming up the nozzle ! so nothing come out of course

Any other idea like "auto001.g" but working ?

“auto01.gcode“ do nothing

:(

 

[Titus 170]

what did you put into auto01.g?

You should let that file start your regular file, so it will heat up first etc just like normal.

...

 

Simple explanation - UltiGCode-flavor is not supported during autostart. The reason for your observation is probably the lack of proper start-gcodes.

RepRap-flavor should work better...

@Titus

I simply renamed me file by “auto01.g" is that not correct ? please detail the procedure I'm a beginner

@TinkerGnome

What is RepRap-flavor and UltiGCode-flavor ?? Can you explain or give a solution ?

Thanks

 

[DidierKlein 729]

I replied in the french topic, but was not aware that you were using a UM2

So first thing:

Change GCode flavor from UltiGCode to reprap (machine settings in CURA)

This will add several things in CURA, temperature of the nozzle and bed settings are now in Cura.

This will also add a start.gcode and end.gcode which does the routine that is normally handled by the UM2.

You can probably simply try like that, the start.gcode might need some tweakings if you don't like it

@didier

Thanks I saw it in french side

Ok, I did that and renamed file in auto0.g but the printing begin directly without the purge phase of loss wire (what is the code to add this?)

there is no info on printer display, it looks less complete than UltiGcode start, and freak me out

Too bad UltiGcode can't do this or UM team do not implement this option in CURA or MARLIN !
