Idle temperature: hotend + hotbed keep hot X min after print finished

[c310]

Hello!

need some guidance:

it happens that i need to adjust something in the printed sample in CAD immediately after print.

• including at the end

[[language]]
M104 S0  ; Set Hot-end to 0C (off)
M140 S0  ; Set bed to 0C (off)

```leads to almost cold tool and bed in few minutes.

* NOT including these commands leads to always hot bed and tool :)

* including some wait (G226 pause) inside leads to a situation that next print cannot be started until pause is finished

????? what is a correct way to keep tool & bed in standby for 10 min and than go off, at the same time if there is new print - not to wait 10 min and start printing immediately

thank you very much!
