Hello, I will preface this by admitting I am a novice.
I have just successfully printed the case for an advent calendar, but the little drawers are failing.
The first error happened because of a cantilever, and the print didn’t connect where the finger pull is (no instructions on whether to use support or not)
Fail #2:I enabled support, but it still failed at the end.
Fail #3: I callibrated, cleaned the bed, and laid the print with the finger pull face down (with supports), but it failed in the middle of the print (no photo). This time it didn’t stay stuck to the bed.
Fail #4: I took everything apart to check the connections and screws. All was good. Same as the steps in Fail #3 and I increased bed temp to 65. But it failed because the filament was not even extruding.
I apologize if this has been asked ad nauseam, but tbh I don’t even know what to search because the print is failing at 3 different stages in the print.
PLA
Layer height: 0.2mm
2 wall loops
15% infill (all as per the print recommendations)
I tried tree support and normal support.
If anyone has any ideas or suggestions I would be soooo grateful. Thank you for your time!
Make unhappy buzzing sound then print to the right?
I’m guessing the 2nd choice. Tighten your nozzle at print temperature. Use tweezers to pull the “sock” off the heater once it is hot and give the nozzle a firm but gentle wrench application.
I followed a youtube tutorial and did as you suggested, then calibrated. The same issue happened again. It completed the second pass of the bottom layer, made a funny sound, and then went rogue.
If anyone has any other suggestions, I would greatly appreciate it. I have tried everything I can find online, and nothing works. The print fails each time, but at least now it fails at the same time.
After the second layer, it makes a weird noise, and the extruder prints to the right.
When printing there is some force up against the tip of the nozzle caused by pressure in the pool of liquid plastic. If there is any slack in between the Z motors and the nozzle tip the nozzle can “Float” and print higher than intended. When the nozzle moves over a non-printed area of the bed it drops back down to the correct height. The nozzle then crashes into the side of the last layer (which is taller than intended) causing the X and/or Y stepper motor to loose counts.
Check the screws that hold the heater block to the extruder body. They are well hidden on either side of the nozzle. They are installed pointed straight up.
If they are tight the next thing is the rollers that hold the toolhead. There should be no wiggle between the X rail and the toolhead.
Check for looseness at the both ends of the X rail. If you lift the printhead can the X rail “tip” in the rollers? The toolhead being in front of the rail pulls on the upper rollers and pushes on the lower ones. Lifting the toolhead with your hand reverses the force on all the rollers.
Then check for looseness in the Z axis (up and down) at both ends of the X rail. Are the motors secured down? Do the lead screws move in the couplers? Are the anti backlash nuts tight to their brackets?
