We believe that we recently replaced a .4 nozzle with a .2 nozzle but we do not recall which printer and whether we replaced the .4 nozzle after we ran that job.
Is there an easy way to determine which printer might have the .2 nozzle? Some color coding or marking?
Pull off the tool head cover, look at the left side.
Also, the hardened steel nozzles have a black body, stainless nozzles are gray. The 0.2 nozzle is only available in stainless.
Slice something for 0.4mm and print it. If you’ve got a 0.2mm nozzle, the first layer lines will have gaps because the spacing will be 0.2mm too wide.
