I bought myself a TAZ 6 a couple of months ago - but do to house repairs taking my attention, I haven’t been able to get it completely set up until last weekend. It is a very impressive piece of equipment, but I think I need to do a bit of tweaking out of the box to get it to work a bit better.
I have printed 4 Roctopuses with the included nGen filament. Only one of them was successful. The first three all had the same exact problem. They were so stuck to the bed, that I thought that the glass would break before I pulled them off. I was able to get all of them off the bed, but they all lost their arms in the process and one of them almost felt like it welded itself to the glass. It took a lot of convincing to remove them. So, I figured something was wrong and it wasn’t just me. I looked at the roctopus that was included with the TAZ. It too had a broken arm, but more importantly, I noticed that the bottom of my print had a hard shell (no lines) and the sample that came with the unit looked very different (lines diagonally across). I did a Google search and found some posts about the Z-axis not being set correctly from the factory. I looked at the skirt and noticed that it was super flat. Looked in the adv. configuration and found that the Z-axis was around -1.400’ish.
I turned it down to -0.300. The next print’s skirt didn’t stick so well. In fact, the skirt pulled up and was interfering with the actual print. So, I turned it to -0.749 and it seemed to be just right. It adhered well. Finished printing and popped right off with only a few taps of the removal tool. So, my guess is that the Roctopus sample was not printed by the printer that I have or whomever printed the sample, over road the machine configuration with Cura. Either way, I think my machine has some more adjustments that may need to be done.
Which brings me to my new issue. All 4 roctopuses (and the included sample) all appear to have a fine webbing between the tentacles and the bull horns of the hand. It is most noticeable on the hand. It appears to be so much so that it has a peach fuzz hair quality to it. Unfortunately, the sample that came with the printer had that particular arm broken and missing. However, looking at the sample’s tentacles - I am sure that the sample had the same issue. I did some Google searches on this and I found that it may have something to do with retraction settings (sucking it back into the extruder?). I saw an Eiffel tower piece with the same issue but much more excessive than my own test prints.
At the moment, I am using OctoPrint on a Raspberry Pi. I have the ability to hook a laptop to the TAZ directly and use Cura, but I would like to stick to OctoPrint as the webcam, remote control capabilities are a necessity long term.
Does anyone have any suggestions on the webbing issue?
