Good recommendations, it's almost the same list of upgrades that I've done to my E3v2. I went with a dual Z-screw upgrade which uses a sync belt instead of a second motor, since I use the stock board and didn't want to run two steppers off the same driver (it should work IIRC, but it seemed annoying if they get out of sync since the printer can't level them individually)
I use it all the time if a model won't come off easily. I grab the blade between two fingers, and then hammer the model from the side with the handle to knock it off the plate :)
Technically the hotend becomes "all metal" with this, as the PTFE-tube does not go all the way down to the nozzle after the upgrade. Best illustration I could find
Hammering the model off is how I lost a quarter inch of glass out of my bed haha thats when I switched to PEI and just flex the plate to remove stuff now. PETG and glass never really got along for me though and I primarily print that on my 3.
Correct it turns it all metal, I just remember being back and forth on what else I needed to buy at that point and really just a good heatbrake does wonders, no larger heat sink or anything at least not until you start changing other stuff up.
Hehe, PETG and glass is a notorious combination, I only printed it a few times but I put covered the bed with blue painter's tape just to be on the safe side. I've never really had any adhesion problems after starting to use Magigoo (which I also never wash off, I just add another layer every few months) but occasionally I get a bit impatient waiting for the bed to cool down.
