RE: Some say use PETG settings with ABS
I started my journey with the first MK2 and went through all iterations up to MK2.5. In parallel got first MK3 and went through all iterations up to MK3s+MMU2. So been there, saw that. Current setup is MK3s+MMU2s and MK2.5. Using the most recent firmware and PrusaSlicer.
Based on your answers it's hard to point you in any direction. You need to be more specific:
- Filament diameter: How much and what is the difference in couple inch apart.
- Nozzle: Where did you got it? Which one?
- PTFE tube can be loose or not flush with the heat break. Loading/Unloading will work fine though it's not placed correct. Read the guidelines how the PTFE tube need to seated and fixed in position.
- By clicking I mean during the print. You should hear it once the nozzle got clogged.
- Regular dirt can be blown away with an air can, no need to disassemble the extruder
The fact that PLA is printing fine is nice to hear but no reference to the root cause why you can't print ABS. Again I hardly believe that the issue is somewhere in the extruder or the filament. With the slicer settings you can bypass some hardware issues but in general ABS default settings should print.

Filament measures 1.71, 1.77 and 1.72mm
Don't remember where I purchased the nozzle. (what is the significance of where you purchased?)
PTFE tube will have to read up on this although carried out step during assembly.
No clicking is heard ever.
Have the following next to my printer and use before each and every print except the acetone.
1.) acetone (once a month or more if the activity goes up.)
2.) alcohol
3.) Glue stick
4.) Canned air.
If you can elaborate on how to make sure the PTFE tube is correctly positioned without taking the head apart?
Here is the spool hope it is readable.
RE: Some say use PETG settings with ABS
It's a pretty big range for the filament diameter but as long as you don't exceed 1.8 it should be fine.
If you got a cheap nozzle knock off, this might cause issues. That's why I asked.
If you don't hear any clicking then watch the print when it starts clogging. What's happening in this moment? How do you clean it? Have you made cold pulls like I mentioned before?
Regarding PTFE tube your right. You will need to disassemble the extruder for that.
Before you tear down your extruder, you can try to deactivate retractions and see if that helps.

RE: Some say use PETG settings with ABS
While researching my settings and material noticed something rather odd. The roll of ABS from Hatchbox that I purchased on Amazon is labeled as ABS white 1.75 +-.005. All the spools I see so far on amazon are +-.003. Did I get an old tolerance spec'd roll?
RE: Some say use PETG settings with ABS
Yes, that is a rather large range considering my roll says on it .005 tolerance.
Do you have a trusted nozzle seller that won't break the bank?
What am I looking when it comes to clogging especially since I don't hear clicking?
Disassembling the extruder is the last item I wish to do but will if it is the problem.
Getting the printer reading to try the setting you mentioned: deactivate retractions and see if that helps.
The printer is heating up as we speak BRB.
RE: Some say use PETG settings with ABS
At least it was successful. But it looks like there are some extrusion issues. Can you post your PLA prints?

Pictures need to be bigger!
Import picture by de media on the forum, then you can adjust the picture, and we can see more info in the picture.
Try different temps, higher and lower, see fan settings below.
A small object will not cool down fast enough, activate the cooling fan, set it on 30 - 40%, if you cool to fast the object will be brittle.
If you print more objects, then the abs has time to cool down, and normally no fan is needed, but here you can try 30%.
try to print slower.
making a bridge then a fan is also needed.
Normally a enclosure is needed for abs, but a picture tent(photograph tent), or a big carton box.

Not sure what you mean by "import picture by de media"

Is this for both the nozzle and bed temp?

Understood more objects spreads out the dispensing of filament and allows the first down to cool.
When you say "slower" where do I apply this assuming you are using the Prusa Slicer 2.0?

Yes in process of relocating printer but mean while the room I print in is closed off no minumum drafts but I understand what you are saying herein.
