I puchased a TAZ 3 a couple of weeks ago, started with nil experience, been learning how to use it and the required software since with some success.
In the last few days I had some drama’s with print quality. First print layer would develop ridges or peaks in the print lines. I went from ok (always improving) print quality to having these problems.
Using the stock L’bot TAZ slicer config’s showed the worst occurance of the ridges… only changes were for ABS filament purchased locally.
Playing with the slicer settings (custom) i did manage to minimise the line peaks, but not eliminate them fully. Once a peak/ridge developes the printer head/nozzle will then follow the ridge and repeat the peak in the next line, thus all subsequent layers would have issues.
After many attempts to improve these issues ( reading the forums, tightening all bolts, trying different filament, different filament settings, removing the extruder to clean, relevelling the bed, resetting all slicer settings etc. changing slicer versions) the extruder heater stopped working during a print.
Can anyone advise where to start looking for a fault with the heater?
I have checked all of the fuses, they seem fine, as do all electrical connections and wires…
Not sure if the extruder has been playing up therfore a possible cause for the printing problems?
I am in Australia, replacement parts from L’bot are at least a week in shipping, but I should be able to source most electronic parts locally.
Really keen to get it up and running again…
