Delay to let bed to achieve uniform temperature

[bignordique]

Never hacked G-Code before.

I wish to print multiple objects covering a large part of the printing surface.

The print bed heater is not perfect. In particular, once the middle of the bed reaches
printing temp, it takes a bit longer for the entire surface to reach said temperature.

I can manually turn the bed heaters on and wait, but hey... we've got computers these days
they're good at this sort of thing.

As mentioned above, I'm not familiar with G-Code. I did look at the G-Code and you
can see it turning on the heater, but there is no apparent wait statement.

How are the temperature interlocks implemented? I'm using Pronterface. I don't see any
adjustments for the interlock. Is there some way I can add a static delay of say 5
minutes between when bed temperature is achieved and when printing starts?

Thanks for any help.

Just add that to the start script

The slicer already inserts M190 to heat the bed.

What you want is called Dwell. G4 S300 will wait 5 minutes.

Parameters
Snnn minimum target temperature, waits until heating
Rnnn accurate target temperature, waits until heating and cooling (Marlin)
Example
M190 S60

This will wait until the bed temperature reaches 60 degrees, printing out the temperature of the hot end and the bed every second

Guess the wiki needs updating

M190 does what it says, but that's not what bignordique asked for. He wants to delay the print AFTER it reaches temperature, to give it a chance to even out.
