settings recommendations for PETG

by SMaric

I have decided to try PETG
Am running the hotend at 240 but am still seeing bad layer adhesion
Have steadily been lowering the print speed -- am now down to around 20mm/sec

Any thoughts on what i'm doing/got wrong

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

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.

endstop Marlin
