@Eclsnowman yes, I print in PET variants almost exclusively now. I still have an urge to master all aspects. 
+Dale Dunn, for PETG, I print on glass with hair spray. It sticks great. To remove it put the plate in the freezer. The moisture in the air softens the spray and the part shrinks just enough to pop the print loose.
@Rick_Sollie @Eclsnowman , the bottom z axis blocks of the eistathios build have these discs. They still popped loose. Time to finish my enclosure I think. 
Buildtak !
I use 110°+C heat bed, PEI build surface and an enclosure that’s heated to 45°C or higher. I didn’t see how you arrived at an 85°C bed temp figure. I’ve never seen anyone recommend that low of a temp for ABS. I’ve not used a brim in a couple years. I do use a 3 perimeter skirt to make sure the bed is level and the lines are packing well without over packing.
@Jeff_DeMaagd I set my hbp to 100c and it tops out at 85 or so. It’s an old 12v prusa hbp and doesn’t like to get that hot.
Pre MK2? I’m pretty sure MK2 and newer will get up to temp as long as you have sufficient PSU capacity. Have you checked your voltage when the bed is on?
@Jeff_DeMaagd it’s MK2. where should I check the voltage at? I have a 360W PSU but haven’t verified what the sticker says. where should I check the voltage and what amount of drop is acceptable?
I’d say if the drop between bed on and bed off is more than 1 volt, it might be your culprit.
I.e. 11V when bed is on, 12V bed is off.
ive printed abs on elmers magic purple disappearing glus on 100C glass with no problem
lots of good comments here, thought I’d add one more alternative. I print on glass, with this product which is easy to apply.
no enclosure (but need one) for ABS, 100C bed, 230-235 nozzle, 30-40 speed. Warning read instructions. I have literally destroyed my glass by fusing the abs to the glass. So follow directions. the 3d-eez +argas231 looks promising as well
I used to have the heat up problem. Found few problems not heavy enough PSU and then cable not thick enough so voltage drop. After both fixed no problems
Hi Glen. how big is your PSU? what gauge wire worked? I’ve got 8g speaker wire (possible culprit. I have not tested the impedence. it never gets warm to the touch.) and a 360w PSU (also never verified, Amazon special.)
Thanks for all the interest everyone!
Mine is 500watt and I use silicon wire Super thick. I’d use wire designed for 15 to 20 amp for my first printer at 12v. Second printer I switched to 24 volt I can themally shatter glass
@Nathan_Walkner you could be right, but I don’t exactly agree with you. The ABS slurry I have used in the past did not perform at the same level as the wolfbite product. Perhaps I should run some tests sometime, overall I’m happy with the wolfbite product. easy to apply and it works.
Your ambient is wrong. You need 60-65C ambient for ABS. No other way.
