All ABS's are not equal. We have been printing with ABS for about a Year and have tried 3 different Filaments 2 of which worked well the best was ABS-x from Mitsubishi Chemicals in Holland and sold widely as a own brand in UK by OOznest and 3dfilaprint the next best we found was also made by them. The 3rd filament whos brand name I won't quote was difficult to get to adhere to any surface and when it did stick but after after mm of print height it warped so much that it split along the layer lines.

The other 2 filaments we print on Tufnol (garalite) sheets with a coating of ABS milk (10g of ABS in 100ml Acetone)
On the simplest (Crudest) of all machines an Ender 3 pro but in an enclosure we routinely print ABS pro and ABS norm. without problems.
