Hi all,
I tried to use blower on printing bridge test and see no difference with and without blower. I assume that shrinking could help in that.
What is your experience, does blower help with bridging ABS or not ?

Blowers on ABS are detrimental to bed adhesion. With ABS, you don't need active cooling of the part. Bridging can be adjusted by controlling temperature, extruder flow rate, and print speed.

I have a setup where my blower is easily removed for when I do ABS.
its held on by magnets.

Never use blower with ABS.... cause shrinkage, bed adhesion issues, layer separation.....

its just bad news.
