ok guys my printers was working great till everything got to thin so i put a new nozzle on and am getting this. using pla. so any advice
It sort of looks like you are underextruding especially since you said you switched nozzles because everything was getting too thin, which also sounds like underextrusion. From that photo, it looks like you might be getting good extrusion sometimes because the lower right portion of that rectangle looks okay. Do you hear any clicking or grinding from your extruder when you are printing? Since you swapped the nozzle I wouldn’t think there would be a clog, unless it is in the cold area (assuming you just swapped the tip). I would probably try the following, in order of difficulty:
- Make sure your x-axis is level. Doing work on the extruder, even just roughly swapping filament can sometimes force it down or up on one side which will make it difficult to level the bed properly. You can just put a bubble level on the linear rail and turn the z-screw manually on either side. I usually start by checking the base as well since your desk or platform my be slightly off level.
- Re-check your bed leveling, especially if you do the above.
- Try bumping your heat up a little (maybe 5-10 degrees). You may be printing at too low of a temp for the filament you are using or maybe your thermistor isn’t reported the right value. Printing a little hotter will help the filament flow more easily. The Monoprice printers default to 195C for PLA (at least mine did) which is usually fine but some filaments like to print a bit hotter.
- Look for problems/obstructions in the filament drive path. You’ll need to remove your filament then take off the extruder fan and heatsink, make sure you don’t let the stepper drop. Check the hobbed gear and make sure it looks clean. Try and slide some filament in through the top of the hot end below where the drive gear normally sits. You shouldn’t feel resistance until it hits the melt zone.
- There’s a possibility something has gotten out of calibration, search for e-steps calibration or PID tuning, but I’d look for mechanical issues first since you said it was working fine before.
Hope that helps.
Looks like a leveling thing to me. If you printed the a leveling braces I’d try that method and then level the whole bed again.
