Can anyone tell me why all my prints are turning out like this on my reprap? And how I can fix it?
a) What is a repeal?
b) Looks like you’re underextruding. Calibrate your extruder as per http://richrap.blogspot.de/2012/01/slic3r-is-nicer-part-2-filament-and.html if you have not done so yet.
I meant reprap, stupid autocorrect, thank you I will try that!
What Thomas said, and also check the hotend temperature with an external probe/temp gun. You may not be getting the temperature you think you are getting.
@Shachar_Weis temp guns can read way-off temperatures, especially on shiny aluminum surfaces, like a heater block. A multimeter’s thermocouple will give much more accurate readings.
@Kaiden_Campbell by the way, is it just the first layer or the entire print that looks like this?
@Thomas_Sanladerer its the entire print, it wasn’t doing this a couple weeks ago, it just started
Did you recently switch filament? You should calibrate your extruder like @Thomas_Sanladerer says.
Just chiming in to back up what @Thomas_Sanladerer said about heat guns. Totally useless for measuring even vaguely shiny metal surfaces, been there, tried it, no joy.
I put a rusty old washer on my heat block, you can get a good reading off that. I agree that temp guns are not ideal though. You can get a good temp probe on ebay for ~$15.
@Spencer_Renosis no I haven’t switched filament, I’m gonna try recalibrating it tonight!
Check to make sure your extruder gear isn’t slipping. If it’s not spring loaded, it may have loosened.
Even if your extruder is spring-loaded, make sure the drive gear isn’t slipping on the motor shaft. I believe that connection is generally keyed, but it came loose on my Solidoodle’s extruder with results similar to this.
