Hi, I have 2 Zortrax M200’s, both provide very different finishes.
The 1st (and oldest) provides stringing:
and when extruding with no nozzle (just to test output) it looks burnt: left
When compared to the newer machine (Right) and it’s finish:
To note, both printers are on same firmware, same file is on both printers
Thanks for your help
temperature problems, check fans if working
try swapping heater&thermocoupler…if nothing change try swapping extruder pcb
when was the last time you replaced the consumable parts such as the hotend or heater&thermocouple? Their approximate lifespan is 350-400 hours (maintenance guide), so they may be already worn-out. As Roby suggested - you can try swapping the parts to check which one is at fault, as well as running the fan test.
Thanks Both, I think the machines have done well over 500 hours
Think I’ll look at some replacement parts!
