Some suggestions regarding support structure display & camera control

[RA1981]

Hi,

as already mentioned (http://forum.raise3d.com/viewtopic.php?f=3&t=1447), I want to make those suggestions "official" =)

Additionally, I want to suggest an option to keep the nozzle/bed temperature at a given level after the print has finished. I think it would be useful to get the print smoothly off the bed.

Do you mean keep the nozzle and bed temperature still at warm value after printing for a set time?
If refers to print removing, the bed temperature may help. But why need to keep the nozzle temperature?

[RA1981]

Hi Vicky,

yes, keeping bed temperature for better removal of the model. For the nozzle temperature, I doubt that it's good for the nozzle to cool down completely, just to be heaten up again if a new print has to be made. So, the idea was to keep the used nozzle at e.g. 100-120°C.

Do you also have any comments regarding the other suggestions I made in the other topic?

Nozzle heating is much faster than heating bed. So that it should not be a big annoying for next time heating up.

About your another topic, sorry, I may miss it. Will check soon.

Hi Vicky,

yes, nozzle heating is fast, but I wonder if it's good for the nozzle to have hot-cool-hot-... cycles. Keeping the nozzle on a "mid-temperature" might increase the lifetime.

About this I would wonder if always keeping plastic inside at half molten state is good or not.
Not a specialist about high polymer chemistry. Just a guess.

if you keep the filament molten heat will eventually creep up into the isolation tube and make a real mess

Hi Vicky & walshlg,

good hint, didn't think about creeping filament.

..not to mention the general deterioration of the plastics itself! Specially if you keep it over the TG temperature. No good!

yeh I just had to do a complete tear down for an isolation tube clog. Not fun. Caused by bad filament breaking so sitting cooking in hotend all night!! So I give you experimental proof that leaving the hotend on is a BAD idea!
