    hello
    on my new print, it wont stick into pre heated bed ( 50c)
    ive used provided glue and spray
    it starts printing ok, but it seems that the heat of bed , dries glue of the bed and the print gets loose.

    please help
    blue PLA provided
    robo r1 plus

    You don't say what isn't sticking to the bed (PLA, ABS, MagicFairy Dust) but assuming PLA it will stay on a cold bed.
    If it is not sticking it is probably the first layer not being pressed down on the bed correctly. Here is what a GOOD first layer looks like (is yours?): https://printedsolid.com/blogs/news/37035715-get-your-prints-to-stick-check-your-skirt

    If not, dial in the Z offset (assuming you are using an R1 or R1+ -- again you didn't say). The Beta is more complicated since it doesn't have autoleveling

    The M565 (startup GCode section) is what sets the Z offset for the slicer. The default is

    M565 Z-1.0

    Which sets it to a 1mm and you need to go more negative (-1.1 for example) to get further from the bed and more positive (-0.9 for example) to get it closer to the bed. If by chance you didn't even put the M565 in your startup GCode block then that is your issue :)

    well, you must make sure that is set in the startup GCode block for whatever slicer you use or the printer will NOT autolevel correctly

    EDIT: and if you are using the small sample blue filament that came with the printer (not on a spool) then throw that away and get some real filament :)

    Here is what I use for startup GCode:

    G28 ; home all axes
    G1 Z5 F5000 ; lift Z by 5mm
    M565 Z-0.6 ; set the offset for auto-leveling mechanism
    G29 ; run auto-level

    Your M565 will be custom, you need to start and -1.0 and run some tests to see where it is perfect.

    Look at the link I sent you.
    That is the screen and the startup block is labeled.
    Anything in there is automatically added to the start of a slice.

    If you need more details you might need to go to the matterhackers forum (they wrote the software) I do not use mattercontrol.

    @Mr Wire only you can make that decision, Mattercontrol I think is the easiest. For now, stick that clump of code @mark tomlinson wrote out for you in the start up gcode sectioin. It doesn't matter what slicer you use, you must have that in there. :D

    Ensure you have the capitals CAPITAL and the spaces in there (copy and paste what he wrote)

    Hello All
    Ive modified the Gcode with very good results
    I had some issue with the first layer, that I think it messed up the total height of the print
    See img
    Any suggestion?
    thanks!

    Still to far away from the bed, when it starts printing the nozzle should be very close to the bed. From that picture, it looks like it's about a half-inch above the bed.

    I have not used MatterControl in a long time, so this may be a long shot, but look at this link: http://wiki.mattercontrol.com/SETTINGS/Printer/Print_Area/Size_and_Coordinates/Z_Offset

    Do you have a number in that box? If so, I believe "said number" will be added to the M565 number you put in the Startup G-Code. Say you have 1.0mm in that box and then you put M565 Z-1.0 in your Startup G-Code, you would actually be 2mm above the bed. Unless 1 cancels the other, which then it'd be best to start a thread on the MatterControl forums.

    Again not 100% sure but if I'm understanding correctly that is your problem. MatterControl tried to make it simple by adding this "feature" but it's actually backwards compared to the Startup G-Code way. So it actually ends up confusing alot of people when they move to a different slicer.
