Layer problems

by SMaric

Hi can't figure out what I need to change to improve this print
210 hot end temp
45mm/s print speed
0.4mm nozzle
0.15mm layer height

this is a test print
2mm base
2mm wall thickness
~50mm tall

tube seems reasonably 'strong' up to the cut-out areas
then is 'strong' again above the cut-out areas
But is very fragile/weak throughout the cut-out area

When printing there was no significant stringing as it traversed the cut-out areas --- so that seems OK

Just cant seem to get smooth layer to layer printing -- can clearly see the 'layer strings'

Hope this makes sense & that someone can provide hints on how to resolve

Thanks

MOSFET boards

by SMaric

2 MOSFET boards have arrived & installed
On power-up the Hot end MOSFET is switched on - even though control board says Hot end OFF
??Does this mean I need to mod the Control Board S/w to invert the drive signal
If so - example please

Nozzle going up after a good G28 and before start printing.

by nicopenna

Hi people, I have this issue: G28 works ok, but when it's going to print after G28 before starts printing the nozzle seems to goes up until the sky, I dont have z_max_endstop so I turnf it of. I've tried with differents versions of cura but the same results. I've check marlin but I cannot understand whats happening. I've checked endstops, probe mounted fix (I have a induction sensor thats trigger oks), also checked the directions and dont know what else....
This is the screen that shows after G28.

Need help finding a replacement part for my A2.

by PaulieGizmo

I'm looking for the piece that the filament runs through that attaches to the back of the cooling fan. I'm not sure what it is called but I have been searching everywhere for this piece. Something snapped inside of it and I am unable to clear it. I need to find either this part or some other hot end that is compatible with my Anet A2. Thank you for any assistance!

E3D V6 Bracket and Turbo Fan Duct Help

by JaycenRigger

Would any of you mind shooting me a link to the E3D bracket you use, and especially if it includes a turbo fan duct?

I wasted a lot of time this weekend trying to print these out of PETG (partially my own fault - crazy winter storm made the basement much colder which totally screwed with my setup). One of the brackets I printed that supposedly mounts to the existing X carriage doesn't mount worth a frig (space left between the carriage and the bracket on the two back screws) and the one turbo fan design I found that was supposed to mate up with 40mm fan for an E3D had the ring too low. My nozzle is actually higher than the part cooling ring.

So, I went through all this trouble to mount this stuff and it's all no bueno.
