Posted · Heated bed upgrade, first layer does not stick properly

So I installed the heated bed kit on my ultimaker original.

The problem is that the first layer does not stick properly.

I use colorfab XT

nozzle: 250 °C

heated bed: 70 °C

speed 50 mm/s

Tiny blobs appear where the layer does not stick, at the next layer the nozzle digs into them and sometimes pushes the print off

I use the glue stick and the bed is properly leveled, the cooling fan not turned on at this point

anyone have a clue whats the problem ?

    Turns out the z axis limit switch was bend witch screwed up the home position at the start of printing.

    fixed that, re leveld the bed and it seems to be better now, but still not the way it was with the blue tape

    I can't remember the magic numbers but I think hotter on the bed helps like 80c - 85. Then reduce it some to like 75 after the first layer.

    For me, when printing XT, hairspray really helps. I just spray it on a paper towel with the nozzle up close so it pools a little and then I swipe it over the glass plate.
