Hi there, I’m a new user of the TAZ Workhorse, it’s my first Lulzbot product along with my first 3D printer. I’m having many issues with the test prints I’ve been trying out. I’m using Inland’s PLA White filament for the test prints.
Stringing - I’ve had pretty bad stringing on all my prints. I’m using Lulzbot Cura 3.6.21, I believe I’m also running the latest firmware on the printer. I run the printing temperature at 205 degrees celsius, build plate at 65 degrees celsius, retraction distance at 7 mm, retraction speed at 25 mm/s, and Outer Wall Wipe Distance at 0, at the suggestion of one of the forum posts.
Jamming, No Extrusion when printing - This comes up at relatively random times, but I think it could be due to heat creep. Almost every jam I’ve cleared, the filament had been chewed away by the hobb. With the most recent jam, re-inserting the filament allowed some filament to ooze out, but when I tried to make another print by itself, it wouldn’t extrude anything out. I’ve periodically checked to make sure that the filament wasn’t being too difficult to pull into the feeder, but sometimes it’ll still not extrude anything even if the filament can move freely.
Print doesn’t bond and parts break near the end of the print. This has been happening specifically to the Benchy test. The initial octo gear test hasn’t broken apart yet, and other prints have had extrusion issues before it gets completed. What usually happens is when the Benchy prints out the cabin, suddenly part of the top of the cabin breaks off and the rest of the print turns into a spaghetti mess. I’m thinking it could possibly be the filament not being hot enough to bond to the rest of the print, bit I’m also worried that the heat from the hotend is creeping to the hobb. Filament is already sometimes leaking out of the hotend slowly whenever the hotend gets hot/ I purge some filament anyways. I’m not sure of that’s normal.
Overall, I’m deeply disappointed with the Workhorse so far. I was hoping it would be a simple plug and use situation, but I’ve been trying to figure out issues with the printer for about a week now. Any help would be appreciated.
