    heat makes for best adhesion on glass- gluestick will stop it from sticking too good :p

    i honestly love ur enclosure- very clean- if u get a chance- maybe re-print it in pet-g there is some study showing pet-g doesnt hold a flame PLA isnt bad- but ABS is horrible it holds fire so easily

    make sure your voltage on ur drivers are set correctly- your Y axis drive might have been running too high or too low

    i recomend taking out those ugly yellow inserts- and getting huge standoffs printed and mounting all ur electronics on the belly :)

    My 1st try with the gluestick got the print stuck to the glass. I heated the bed to 70 and it came off with force but wasnt ideal.
    Hairspray made a few prints come unstuck half way thru.
    Adhesion to the magnetic mat worked so well, maybe ive stuffed up the z height with the glass.

    Thanks,I like the simple box also, and ill look onto reprinting it with pet-g.

    Looking into dual z upgrade- there are a few cheap($55) kits for cr-10 standard on ebay.. mine is a cr-10 mini.

    i could be wrong but the difference between cr-10 models is bed size and bed height but the aluminium extrusion and steppers are the same
    So a dual z kit for a standard cr-10 should fit my mini CR-10 but i'd have to cut back the lead screw to the same length as the existing one. Unless im missing something?

    use cheap hairspray to help the 1st layer stick to the glass bed. It's what i use and it works well.

    ofcourse, you just need a light spray on the bed. It makes it ever so slightly pourous and tacky for the hot plastic to bond to.
