Welcome to the SeeMeCNC Community

I FINALLY have my printer running consistant!....sort of...

After finding one of the stepper teeth was EVERYTHING and fixing it, now it tweaking things. The print on the left was my first print and it came out ok, but the print on the right was the next print and I got the squigglys. Not sure if it the temp, cuz the first few layers came out somewhat ok.

ALSO---Im noticing a consistent issue where my printer doesnt lay filament for the first 30mm (usually when laying the outer ring) then its starts laying. I even had some extrude before starting a print, but same issue.

What type of filament are you using and what are the temps of your Hot-End and Bed?

PLA, 190 & I only had the bed temp at 35c. My ASSUMPTION was the bed is to prevent curling, so I was playing with the bed temp, but didnt think it would have any affect on the higher layers. Also, I dont have a fan cuz I cant print one, lol. If Seemecnc sold one, I would buy it.

Temps seem good. You should have a fan for PLA, There are some simple fan mounts on Thingiverse that connect to the effector, perhaps you can print good enough just to
print the fan bracket and add a fan to the bracket. I think most accept a 40mm fan. With PLA you could probably print on a cold bed if you used painter tape on the glass.
I would also experiment with the Hot-End temp by raising it by 5 degrees or so and see if that would help with adhesion of the layers.
Here is a fan bracket for a 40mm fan that is kind of crappy but it should be easy to print and may help you print something better.

Where did you get the PLA? I print at about 175C with SeeMeCNC Sky Blue because when I print at higher temperatures it oozes too much. When I checked the temperature, I also had verified with a thermocouple that I was getting a similar temperature (it may have been a few degrees lower on the thermocouple than what the thermistor was reading).

Another thing I've started doing is to manual extrude filament with different temperatures to see where it comes out easy enough that it's not curling up a bunch at the end of the nozzle, but not so fast that it starts oozing a ton.

Try using a Z lift of 1 mm, if the hotend is held up at all you can get weird squiggles.

Are z-lift and hop on move the same thing? Is this offered by all 3 flavors of slicer?



As to the original question... What are you using on your heated bed? Hairspray, blue tape, glue stick, etc... (derp, look at the picture, right!) It looks like your print came unstuck form the bed and was moving around with the hot-end. Was it attached to the bed when you killed the print? I would play with your bed-temp.

Sounds about right, Z-Lift is the Kisslicer variable for moving the hotend up when traveling.

Could you elaborate on this? Mine HAS been sort of curling up and was also starting to affect the print because a piece would stick to the nozzle during a print then pull or deposit itself somewhere else.
