    it will save 1.5 minute before printing :)

    The bed takes a long time to heat and the nozzle doesn’t take long at all. If the nozzle stays hot for a long time, it will burn the material in the nozzle and can lead to clogs and other issues. On my machine, I wait about 30 seconds for the nozzle to heat as it starts when the bed is 5 degrees from target.

    While there may be more refinement coming, this is about optimal behavior for the system and for reliability.

    mine took ~1.5 mins to heat up the bed to 65 degree then it start heating up the nozzle to 220 degree, in ~1.7 mins mark the bed already 70 degree, whole process took more than 3 mins then start printing.

    guess my bed is harder to heat up……..

    The bed does take a long time to heat up, whereas the nozzle should be fairly quick. As @BHudson says, it could do with refinement.

    During beta, they both heated up at the same time, meaning the head sat there full of stationary hot plastic at 235ºC waiting for the bed to get up to temperature.

    What would be nice to see is some intelligence to maintain the bed and nozzle temperature for a short time rather than instantly turning them off whenever anything stops. However, I guess when a print’s finished you want to start it cooling down as soon (but not as quickly) as possible.

    these timings are perfect information for our wiki …

    @pelgrim I will add info to the Wiki when I have time. Right now I am working on finding new employment, getting my Robox to actually work, writing a service tech manual for Robox, and keeping up with the forums. So the Wiki has fallen to the wayside for me at this point. Once something settles down, I will work on the Wiki also. Feel free to add anything that you think should be added based on my posts here.

    that’s funny, we have exactly the same agenda, with finding a new job also being the top priority.
    Guess we both understand by experience that searching a new job is a huge undertaking.

    Indeed it is. Sorry if I came across as cross.

    Getting a full-time job is a full-time job!

    Any ideas you do have are appreciated, even if they’re just suggestions or outlines for things someone else can write. In the meantime, best of luck to both of you in getting new employment, ideally something more fun that my current work (which involves real estate agent websites in PHP… I have no idea what I did to deserve this!)
