been looking at your videos for some time, amazing work man! wanted to ask what surface you re using, looks like PEI coated with some adhesion spray or goo, but could be anything and wanted to know for sure
It's smooth PEI. It looks like that for 2 reasons. I sand the PEI with sandpaper to scuff it, to make more valleys for the filament to sink into(like painting on a smooth surface vs one with scratches). Sticks like mad after cleaned with dish soap and a green scrubby. But after some time I am lazy when it starts to not stick again, and put some glue stick for some material that never sticks to anything. That residual glue stick makes a whitish color to the bottom of the print and also on the plate.
I’m so interested too in what PEI is that. It looks a modified sheet with an adhesive Buildtak PEI or something like that. Can you please tell me what kind or brand of PEI do you use please? 🤗 Thank you so much my friend! 🤗
@@MrRocksalt Yes I know it, but im curious because your plate looks good for me. I’ve a VzBot and I don’t get any decent PEI or spring steel plate. Do you scratch the spring steel first and then apply the PEI or something like that? 🧐 Thank you so much for your reply!
@@guzmangomezguerreiro3418 I believe PEI is PEI, unless whomever sells is selling something else! If you have issues with the glue, welcome to the club! I have much better life from the glue with temps
Great print ! Looks like the changes have been very helpful in all areas! Hope you find out about the seam? Would you need to revert to your old settings ?
I think it's just too fast. I pumped up the acceleration on this one and the square corner velocity. I think the previous ones were 7 minutes vs this at 6. Probably overheating, but the top of the model is not as cooling sensitive and still there. I need to make a few changes back to where I had the extruder acceleration set. When I watched the part print, it seemed like there was a stall at each layer change. Maybe that stall was enough to overheat the plastic.
What hotend is that? What's the max flow rate that you're able to push with reliable print quality? I can push my std6 to around 55 with abs before the flow starts to strain and cause defects and I could push it to 70 for benchys
This is Goliath and can flow 92 with 0.4 CHT, I don't care for the print quality with CHT so I use tungsten carbide nozzles and limit my flow to ~65-70 in slicer.

@@guzmangomezguerreiro3418 Gizmodork PEI. A lot has to do with how you prep it.

This thing scares me a lot
