I dont know what I could be doing wrong. Im using ABS 1.75, extruder temp at 260C bed at 70C, 75mmps print speed. Im using abs slurry on glass. What am I missing?

Your flux capacitor is out of whack. Needs to be recalibrated.
What's wrong with the print? TLDR version.
well your printing temps are really high. Black abs should print between 220-240.
I think pet prints higher but you definitely shouldn't be printing abs at 260.
Ok, I'll try it with a lower temp and see if it helps, thanks for the advice
try either 235 or 240 initially.
Different colours print best at different temps. There's no actual ideal temp for all abs filaments. I've got a white abs that prints best at 220.
Ok Im trying the print at 230c etruder and 110 for the bed, Ive been reading allot of people printing with that bed temp
Printing at 230c didnt change anything. Could I have just gotten some junk filament? I also cant get the bed to stay that hot, it will only go to about 89c and wont get any hotter. Maybe time to get a better hot bed
so what's the actual issue. The video just said it was great.
I am confused :-)
the print looks awesome on the table after its done, as soon as you grab the print looks are obviously deceiving. the whole print falls apart. its like none of the layers are attached to each other and are just nice and neatly placed on top of each other.
AH... so delamination?
The quick and dirty solution is Acetone, paint it on or use a vapor bath to melt the layers together, but if it's falling apart immediately, then it could be a temp issue, and you won't get it to an acetone treatment.
Do a search here for "delamination" and you'll find multiple threads on the issue.
Ok thanks, I noticed when I got the bed temp up (used a heat gun with the bed on to assist in heating) to 110c there were parts of the print that were strong and didnt come apart. But the bed I guess cant sustain that level of heat and slowly fell back to 86c (yes I changed the setting for the bed to heat to 110c).
Ok just got the new heatbed in today (original is attached to the bottom side of a 3/16 piece of aluminum) Im going to install it and see if I can get my bed temps up to 110 this time. I'll post the result later tonight and see if the heat bed was the issue
Oh just for reference I ordered the MK2B bed from ebay (the red one) to upgrade from the one that came with the A600 printer from ebay (prusa I3 clone)
Okay, the MK2B bed is soooooooooooooooooo much better than the one that came with the printer. Heat up times are a third of what they were, it gets to 105c with a hesitation. The print came out a little better than before. I think I might have to get a "Enclosure" for the entire printer to keep the print nice and warm, my only worry is all the printed parts on my printer are made from PLA, with the enclosure would I be risking the integrity of these parts? Ive heard they will get "soft". This would be good for my extruder lol
there's now way you should be getting serious delamination with abs at those nozzle temps.
I had the occasional crack - but never anything seriously structural.
And why are the printed parts of your printer pla ?
Did you make it yourself ?
Otherwise that would be pretty weird.
Personally I'd say no 60c wouldn't effect good pla. But parts under mechanical stress, dunno.
Very unusual for a printer to have alot of pla parts though.
What size nozzle and layer height? Your layer height might be too large.
