Hello,
am still new to printing and in testing to find the best setup for nice first layers. I figured that beside
a nicely leveled printing surface its also essential to have enough fillament being extruded at the right
speed to touch the surface and get a chance to stick to it instead to stay attached to the nozzle.
Priming the nozzle at 0,0,0 and using 40% first layer speed enabled me to get my first prints started without
too much first layer detaching. Useing 1 raft layer is also really nice, since it creates a fillament surface on a pathing
where all the fine hair strings drawn sometimes get no chance to interfere by hitting the nozzle, getting stuck and detaching
more parts from the first layer in the further movements. But I cant remove the 1 raft layer from my final object afterwards.
(Off topic: A hint for a good raft layer setup is Welcome)
Since the priming at 0,0,0 causes fillament to be build up and “contaminate” the outside shape of the nozzle, causeing
alot of fine hairs to be drawn towards the print and eventually causing trouble there later. Here my idea for a possible improvement:
Is it possible to do the priming on a predetermined path towards the area where the objects are going to be printed or along the edge
of the printing board surface (x-edge or y-edge). I`d really like to do some testing with such pathing and see if I could keep my
nozzle clean from buildups and therefor less thin hairs of fillament drawn.
Regards Ark.

interference and USB connection issues.
