Hello guys (and gals). I just bought a Taz 5 a few weeks back and I’m having a little bit of an issue with the prints. I would say about 50% of the time the print fails. The screen stays on, bed and nozzle heated, but no movement from any stepper. LCD readout says printing still.
I’m printing from an SD card (the one that came with the unit) and have the Taz connected to a voltage stabilized UPS. I’ve used both slic3r and cura to generate the gcodes. Usually it is longer prints that fail, but I have had it fail on the second layer of a small print. Usually I reslice the model and it runs successfully, however on the small print I reran the same gcode and it failed in the exact same location. This leads me to believe that the gcode was bad. Resliced it after that and it completed. I have also had models fail 5 times in a row at different points each time (each time I resliced it and generated new gcode).
The models are all made in FreeCAD and none of them showed any manifold errors. It appears to be an issue with the gcode being generated, but it is intermittent and happens with two different slicers. I never know if the code is good or bad until hours into a very long print, sometimes 90% through. This makes it incredibly frustrating and difficult to diagnose. We use this machine to print plugs for FRP molds, so when a 40 hour print fails at hour 32, it sets us back an entire day or more on each project.
