ABS printing issues.

The link doesn't work and I cannot see any photos.
Which extruder are you using ?

I have the Qidi X CF-pro and I gave up with the standard extruder and just used the High temp one. I only use ASA but its similar to using ABS I believe.

Prusa slicer gives me better results than the Qidi slicer. I no longer rely on the auto bed leveling but manualy leveled the bed using one of the many public domain layer height STL files available from such as Prusa Printables.
I just shimed the PEI plate up by sticking strips of adhesive aluminium foil to the underside and set the springs to firm.Just kept checking the layer height until I was happy.

Unfortunately my Qidi X CF pro is not very consistent with results, generally more bad than good, several faulty parts have already been replaced.
