Success!

Finally after multiple build iterations and changing directions a few times I'm finally starting to see some successful prints. Thanks DC42 and anyone else who endured my ramblings and stupid questions.

the biggest lesson ive learned is WATCH OUT FOR GARBAGE CHINESE COMPONENTS!!!!!

that has been the biggest hurdle. now that i spent some money and bought a budaschnozzle my printer is extruding reliably and i can actually tweak settings to get what want. Next step is to get rid of the seemecnc knockoff heated plate and find something a little stronger (dont get hot enough for my liking)

biggest issue im fighting at the moment is bed adhesion. I've tried abs slurry and hair spray and its only been marginally effective. I have a roll of kapton tape on its way.

i still have more cleanup to do on the build with hiding wiring and re-routing some of the cables.. and eventually i want to add a paneldue to it...

Congrats!
What motor do you use for the extruder?

its just a short bodied nema 17 stepper....40ozin i believe

I plan to build a delta with extruder directly on the platform too. I would like to achieve about 7g.
Can you post what maximum acceleration you can achieve with your setup?

not sure... im still having adhesion issues even after a successful small print so im still running normal speeds

what would be a good cause for mid layer adhesion issues?



PLA nozzle temp 210c
bed temp 50c

pronterface and slic3r for my software...

anything i should be looking for? anymore info you would like?

What's your retraction settings? With a cooling fan, if you retract to much the filament cools down and blocks the nozzle for a short time.

4mm and i have it lift the head 4mm to help eliminate it from dragging on the print.

extruder ratio is set to 1.2

Try lowering your retraction from the range 0.1 to 0.5mm (not the lifting, that's not an issue I believe), start low and find the sweet spot so your hotend won't leak and your filament won't cool down.
All you want is to release a bit of pressure from your hotend but you don't want the warm filament to cool down.

You might also want to play with lowering retraction speed, that could also be a factor.

will do thanks!

When I get that first suspect is the filament not coming of the spool smoothly. Second check is variation in filament diameter (I use cheep stuff).

ive had too many issues with chinese e3d knockoffs that ive been watching that like a hawk. that hasnt been an issue. the filament is Makerbot filament...the replicator 2x we have at work doesnt like PLA at all and will only print abs reliably. so im using a roll of it in my printer.

ok...this is a quirk thats really bugging me with pronterface. I have it set for circular build platform... and in slic3r my parts are in the middle of the build plate..

pronterface has them out in left field. ive done some internet searching and come to the conclusion that i should be able to update it in the settings... however those areas are gray'ed out and there is no where to adjust...

I had this issue last night using Pronterface for the first time. My XYZ offsets and home positions were not grayed out and I was able to put in an X/Y offset of -75 with X/Y home pos. of 75. This centered my print. Not too helpful for figuring out why you don't have that option, but that is how I solved the offset.
