I will try this, but first I found another issue to be resolved. The PIE is lifting in several places, so I need to redo that. I noticed that when I laid down the PEI, there were some air bubbles that I couldn't get out, so that has to be resolved first. I may go back to the old glass and hairspray which has worked for me for years.

I just finshed a new coreXY build and ran some test cubes (20mm cube). I was very impressed with the results. I tried a larger print, but had to change filament before I did (MH PLA 3mm). I started the print and all looked well until I realized that one part of the print had delaminated. This is the first time I've seen delamination with PLA. I stopped the print and found that If I touch any layer with my fingernail, it delaminates with virtually no pressure. The layers don't seem to be bonded at all.

I went back and did the fingernail check on the 20mm cubes and they are solid. The only difference is the new spool of PLA.

The particulars are
3mm PLA white (matter hackers)
extruder temp 185c
bed temp 60c
0.4mm tip
0.3mm layer height
No fan engauged

I am kinda at a loss to figure out what happened. Any suggestions?

I recently received my Titan Aero. The thermistor connector is something I am not familiar with. Can anyone give me a part number or digikey model skew number so I can order the matching connectors?

Can anyone tell me approximately how far below the mounting surface of the titan arrow the tip hangs. I have a machine I built several years ago and would like to use this direct drive extruder, but I am limited on how low the Z can go. At best, it will be close.
