I’ll take a look into it. Thanks! I do have a silicone sock over the heater block if that’s what you meant.

Same here. I basically gave up on PETG- which is a shame because I have to spools of it. 🤦🏼‍♂️

I haven’t. That one was from the official benchy website and worked well for me on PLA

@@NerdsWithFriends Did you ever get the issue worked out with printing PETG?

Thanks for all the input! I’ve been using the provided Lotmaxx flavor of cura (cura 4.2) - but I just read a review on Amazon that said cura recently(ish) added the sc-10 as a preset. I am definitely open to swapping over and giving vanilla cura a try- I just assumed they were pretty much the same. I have drifted from their stock setting a bit and I do use magic numbers. What is the benefit of disabling z hop? You’re right! Z hop is set to 1mm.

@@NerdsWithFriends Yeah, the Cura 4.5 has the SC-10 added now, So totally worth giving that a go. Regards the benefit of disabling Z hop, if your retraction stating are not bang on right or you're using something that loves to string like PETG when it "hops" the Z-axis moves up as it retracts and Iv found this can leave a little bit of plastic that can at best leave imperfection on the print and at worse give the nozzle something to hit on the next pass (worth watching print and seeing what happens when it hops easy to spot, nozzle stops moving and it get louder while it lifts the Z 1cm) as it has to perform a retraction and lift the Z 1mm every layer it adds a fair bit of time to the print and is there to fix an issue most people don't have (the nozzle rubbing against a printed top surface and leaving scars on top solid layers), and if you do have that issue then switching the setting to "Z-hop only over printed parts " gives you the best of both worlds, but 1mm is far to hight IMHO, if have a well-calibrated E steps, having it more then say double your layer height would imply you're putting out far too much plastic. So in short Z hop fixes issues you shouldn't have in the first place and adds a lot of time to your print..... I hope that helps, and just ping me if you have any questions! (about to start some PETG prints now, so will let you know how I get on)

Pigeon Print yea- I’m pretty sure my printer rubs the top- bad. I did just by a z-screw backlash nut to hopefully help keep it from drooping.

@@NerdsWithFriends let me knowhow you get on with that! Been having a little struggle with PETG, sticks to well to the bed, and need to dial the retraction, was ruining 4mm at 40mm/s for PLA, but think I'm going to have to bump it up for the evil that is PETG (it's not that bad, just when you got an enclosed printerfor ABS you ever need to really use it, so Im a PETG rookie)

Pigeon Print no luck still. I just ordered some new thermistors- hopefully that will do it.
