    yes I use the heatbed with PEI. You are limited mechanically as to how much usable build area there is on the bed. I asked @Printed Solid to cut them to fit the whole bed so I didnt' have to guess where the full build area is. (the 10x15") and frankly...it looks better :D but build volume is the same ;)

    Both are right. The physical build area is the same, but with better adhesion you need less heated bed to make adhesion work so you end up with more workable build volume.

    Went ahead and ordered a sheet, hopefully it will help with adhesion during the winter.

    Would you still go Mesh with a brand new bed or do you think the UBL would be fine? I'm sure I'd have to relevel after install do either method would be fine.

    All of mine are manually leveled so I'll defer that to someone who still uses autoleveling :)

    I'm not opposed to manual either, but I haven't come across R1 specific instructions. I have seen mention of a business card and thumbscrews

    I dont know that there is much difference between UBL and Mesh. Mesh is what I have so mesh is what I use :D. @WheresWaldo may have a different opinion or bit of advice regarding that.

    Not R1 specific, but the principles are identical across any printer. Takes some time and some shims :)

    Funny, I actually have that bookmarked from a few weeks ago, but I saw no adjustment screws on the R1 bed

    True the beta had them. You either shim the plates at the bed and/or shim under the glass bed between the magnetic mounts.

    Yeah, I just have the four magnets. Of course someone got a little overzealous with the glue so not all of the corners sit the same.

    Where the bed mount to the base of the printer is also a fine place for shims :)
    I only needed that on one of them

    So, quick question in regards to probing the PEI cold and the startup script.
    Right now on the stock bed I always preheat and load my filament before starting, so it probes hot and leaky.
    How do you end up having enough time to load the filament and manually extrude before the print actually happens if the last command is actually the extruder temp? It seems that would only give seconds to load before printing starts.

    Your material should be already loaded prior to starting a print. So...heat up load filament. Cool down, clean off any goobers when cold. Start print

    @Geof - Is the Buildtak Spatula worth the investment over the tool that comes with the machine?

    As I am thinking of finally trying printing with ABS, at what point will the bed temperature lead to the adhesive trying to lift from the bed?

    I dont know, you may want to contact @Printed Solid and ask. I dont print ABS on my Robo R1 series machines, to open and not worth the hassle for me when I have machines that do it very well. I have printed up to 100 C on my Prusa, but I cant guarantee his PEI is the same as Printed Solids.

    I'll have to search through data sheets to get you a number on that, but I can tell you that we've run prints with the bed at 115 with no problem.
