Check this page for all troubleshooting issues related to our 3D printers.
For more information, refer to the troubleshooting suggestions at ALL3DP.com, from which the below items are adapted.
Printing in thin air and no filament is coming out:
Supports are difficult to remove
Underneath overhang is messy
Print stuck to bed
Print not adhering to bed
Corners are not sharp and are lifted
Gaps in the infill
Layer does not line up with the rest of the print
Can see infill through top layer
It’s possible the filament is clogged, scraped, and/or in need of priming. Increase the nozzle temperature to 210 degrees. Move the extruder a few inches above the bed allowing space for filament to extrude. Remove filament. At a 45 degree angle cut off any scraped or scratched up part of the filament using scissors. Insert filament back into extruder (don’t lock it) and by hand push the filament cord down into the nozzle. The filament will then extrude. Keep pushing until you see the filament extruding smoothly and clump free. Lock latch. Restart your print.
Also, make sure your using the provided start G Code. With the right G Code it will the printer to prime the nozzle before starting each print, which will allow filament to extruder immediately upon start.
If the touchscreen on the TAZ Pro Dual Extruder or TAZ Pro S goes blank after inserting the USB drive
If your print fails during calibration or the first few layers of your print and the message "Extruder 1 Filament Error" appear on the touch screen
For Workhorse 1 & 2 as well as Pros 1 & 2
If the printers are working but the quality has become noticeably unsatisfactory, then restore the default factory settings on the printer
To restore default factory settings on one of the Lulzbot Workhorses:
Press in on button>Configuration>Scroll down to Restore Defaults
To restore default factory settings on one of the Lulzbot Pros:
Menu>Advanced Settings>Restore Factory Defaults
Once factory settings have been restored, the pros need to have the runout sensor turned off or they will not print. To do this:
Menu>Advanced Settings>Filament>Runout Sensor>Switch it off>Press back until a pop up asking if you want to save the settings, press yes
If a print fails on a Lulzbot Workhorse due to the print slipping out of place from the print bed, the first fix to try is to auto calibrate, auto home, and clean the nozzle. You will need to allow it to run through each process before you can tell it to do the next one. To do these Processes:
Press in>Motion>Auto Calibrate
Press in>Motion>Auto Home
Press in>Motion>Clean Nozzle
If the above homing, calibration, and cleaning fix does not solve the print slipping, then slice the stl file again and add either a brim or a raft in the bed plate adhesion custom setting. Also, put blue painters tape on the print bed, as smooth and flat as possible.
If a print fails on a Lulzbot Pro, and only a little strand of filament has been extruded, and the screen says Extruder 1 Filament Error, then the run out sensor needs to be turned off. To turn off the run out sensor:
Menu>Advanced Settings>Filament>Runout Sensor>Switch it off>Press back until a pop up asking if you want to save the settings, press yes
