Re: esun petg
last I heard that was still the plan (about a week ago when I spoke to him) Im looking forward to seeing this in black
Re: esun petg
Okay so I tested my first spool of eSun PETG (electric blue) last night and suffice to say, it didnt go well. I had the nozzle at 245 and the bed at 110; and treated the glass bed with a few coatings of GlueStick.
The cleaning cycle off the side of the glass usually resulted in a huge mass if sticky stringy goo stuck to the nozzle but I learned quickly to grab it before it did its wipe. After getting though that, I found the nozzle seemed to run its first line of the brim without too much trouble, though as soon as the nozzle got back to the start of the loop, it pretty much grabbed a hold of its own layer and dragged it along for a ride of loop-2. This seems like really stringy stuff, I cant seem to keep it planted on the glass; all it wants to do it drag along behind the nozzle, lol
I can probably post a video if needed, but is this typically a sign of the nozzle [or maybe the bed being] too hot?. Even when resetting the system for another attempt, the stuck-down section of the brims were really never "stuck" with any sort of confidence (a tap of the fingernail and the part pops off, even when cooled).
Any insight welcome
(PS - I did manage a calibration and the modifer at .85 seemed to give me a pretty clean .4mm (which is what its set to)

Re: esun petg
Try 250, make sure you're not printing any faster than 60mm/s max, print the first layer at 50% speed. I have had a few problems with layer adhesion, but it is intermittent. I do find I need to use a heavier coat of gluestick than usual. Try it at 100 bed temp as well; my friend has been printing at 90 and reports no adhesion failures, so maybe too hot is as bad as not hot enough.
It does tend to stick to the nozzle more than PLA or ABS. Make sure you have 200% infill width and don't randomize your infill, to prevent the infill from breaking up, getting stringy and collecting on your nozzle.

Re: esun petg
I actually run the bed 70-80. Never hotter than that. Its just not necessary. I dont know how that works with glue stick though. Maybe you need hotter with that. I use hairspray and it sticks to that like crazy but pops right off after cooldown. Pet requires a first layer to go down perfect so the bed gap needs to be right on the money. First layer cant be squished onto the bed otherwise it will collect all over the nozzle.
Re: esun petg
I just picked up a few extra panes, so I'll set one up for my trusty can of mega-hold and try again at the lower temp. Stay tuned!
Re: esun petg
This is a profile Ive tweaked alot but here are the items I look to double-check before I hit go
245 nozzle
75 bed
.2mm retraction
5mm wipe
125% first layer
50% first layer speed
100% fan after layer 1
3200 mm/min
I'm still having a bit of trouble when I print more than one item tho, keeping those corners stuck down is a pain in the butt. I wish the brim feature extended out passed supports as well.

Re: esun petg
Are all-metal hot ends being used for these PET prints?
Re: esun petg
doesnt need to be all metal. it prints at standard abs temps. 245-255.
