So, I was following the instructions to update the firmware, however, when I Cura's Automatic Update prompt came up it said my firmware update version was UNKNOWN, so I grabbed the .hex file for the version the latest version from GitHub (probably my mistake), and told it to update. Immediately my Mac USB disconnected and the Cura said the printer was no longer connected. The LEDs went green then red and it stayed in that position for a long time. So, now my Sigma won't boot and when I try to turn it on the right extruder goes left and hits the other extruder and starts making noise. Any chance there is a way to manually update the firmware without Cura? I cannot connect Cura to the machine anymore it won't recognize the Sigma. I am stuck and opened a support ticket with BCN3D. Any advice.
While attempting to hot tighten, I had the parts laid out and plugged in, but not assembled inside the print head when I got the error.
In desperation, I assembled the print head on the printer, and then started up printer. Found Home, raised the print head 60mm and over on the X axis until I could fit the wrench (about 150mm or so). I raised the temperature and no error thus far.
Lesson learned, hot tighten on the TAZ 5 fully assembled.
@badincite depends what they are printed with. I printed all of my hotend mounts using carbon fiber nylon, which is strong enough to take any collision. If the metal ones are inexpensive, I would go with that.
Looks like my bad. Accessed the board and I was plugged into E1 instead of E0. Extruder now feeding but not laying down. Noz =215 bed =75 speed= 50 don't know what to do with z setting .2mm noz gap. stock pla trying to print bengy. nothing sticking. thoughts?? Thanks, Joe
You describe the exact situation I find myself in today. Recognizing your post is nearly 2 years old, I wonder what printer you chose and whether you were satisfied by its performance. Please let us know. I'm ready to pull the trigger on a good printer but would appreciate an objective review.
