I had some black PLA filament that would not stick. After I turned the heat up to 220c then it started to stick to the bed. And of course make sure the bed is probably leveled.

You need to monitor the first layers to see what happens.
It might be a bed leveling issue.

Did you guys got it up and running on the a10? And what speed? Features etc?

A new print head fixed the issue.

New printer head in place the new one is not leaking.
I will order a spare head for next time I have to replace the nozzle..

The new printer head is replaced after some help from vert.. regarding the eccentric nut...

Yes, I did this today The heater cartridge is easy. Unplug the green connector (it just pulls out) then loosen the 2 flathead screws and the wires come out, easy peasy The thermister is a lot more tricky. I did manage to get the connector out in 1 piece, I got it down next to the wheel, then carefu...

as for the fans inside the cage they are meant to be on all the time to keep the upper parts of the print head cool from the heater block.. you would not want your filament turning to mush before it hits the heater block and nozzle... Aaaahh so its meant to be running at all time/always. Good expla...

I have ordered the print head from the geeetech spare part site.
Did you guys manage to replace it without removing the wheels?
I'm still waiting for my part though...

Is this the spare part you mean?
