Hello,
I wanted to post a noted which may help newbies to PEI and NGen, like me.
Before I bought my Taz6, I was using Delta printers with Glass or Blue tape. I printed PLA/ABS/TPU and never had any problems with the removal.
I love my Taz6. The auto level is flawless. The materials stick great! But I have had issues getting the NGen to release. NGen is now my favorite printing material. I use glue stick and let the bed cool fully. I have tweaked my Z offset so it is actually almost too high and still was having issues with it releasing. I really had to work at removing the print. I printed the large gear for the extruder and it literally took my half a day to work it off without damaging the bed!
After reviewing the forums and youtube, I tried tapping the print, different tools, isopropyl alcohol. I still struggled. Then, I ran across of post about using a mix of water and 70% alcohol. I let the bed cool to 50 degrees Celsius and spray the print. Come back in 10 minutes and the print is completely loose from the bed. No tools, No Taping. I am amazed. I have adjusted my Z height down further for a smoother bottom and it still works great.
This may be common knowledge but I thought I’d pass it along and hope it helps someone.
