    So the filament load wizard only has pla 190 and abs 230 as options. I want to load a polycarbonate abs which is labeled at 270-290.

    Will the following procedure work?

    Use temperature control at the touch screen to manually raise the temperature to 270, then run the filament load wizard for abs, which should immediately allow me to go to the next step ("press enter when you see filament extruding").

    Also, I am using polycarbonate because I am printing a pipe that needs to be able to withstand a bic lighter for acute intervals of 2-3 seconds. Is this ideal or would another filament perhaps be a better option?

    Temperature deflection is best on PolyCarb (150° Celsius)
    BluPrint is not bad at 110° Celsius

    Look around, but most everything else is less :)
    (ABS is <100, PLA is 65, PET and PETG? Nope, less)

    You can find a couple of nylons that are in the same ballpark.

    @mark tomlinson Thanks. In terms of loading that filament will the procedure I had outlined above work?

    Sure, that would be fine. You could also just do it manually :)

    on the R2 when you go through the wizard there is an option that says create new or something like that because I've added a few. I cant recall if it was a new create or an edit feature that I saved........... R2 is not with me right now so cant check for you

    On the C2 / R2 when you select the Load Filament Wizard there is a '+' icon in the top right corner, there you can add your own.

    Now here is a pretty dumb programming decision. When I load or change filament I don't want to waste time heating the bed also. RoboOS uses the same parameters for pre-heating as it does for filament loading and changing. So if you zero out the bed temps here, the pre-heat wizard has zero for bed temps. And why isn't there a wizard (they like wizards) for just unloading a filament?

    I don't know why I haven't opened a GITHUB issue on this ..... Oh wait, I know, they are ignoring all issues in RoboOS.

    No, they are ignoring the GitHub entirely.
    Token open sauce compliance :)

    It takes extra work to do that sort of thing right and I get that there will be a noticeable 'lag' but it should be updated.

    I opened an issue anyway. I also posted on the Elite FB Group hoping to shame them into following up on open issues.

    Maybe not, that group has Braydons attention at least for now.

    It is something you just need to add to your workflow as a developer (like doing a commit and push to your version control) so maybe they do a little extra work, but ... not a lot

    Umm no it isn't, yes they use the same parameters but the bed temp is ignored for the filament load/change wizards. The bed doesn't heat.
    Which is kinda annoying since it always forces me to manually start the bed heat first...

    Good to know, I changed them all to bed 0°C anyway, so I did not see it.

    It's convenient to have the right temp set since you can then tap Temp->preheat->select material and you're done.

    The PC I have prints nice at 250/90 BTW.

    90°C bed is about as high as I can go without modifying the firmware to wait longer and avoid errors. Of all things not to improve from the R1 series, the choice of bed heater is odd. But that discussion is for another thread.
