blobs of slag on stainless 11gauge
(OP)
I am cutting 11gauge ss on a bytronic bystar 4020, 2800watt.
I'm having some difficulty with holes and tight slots, I end up with small hard blobs of steel at the pierce / leadout points
I have an arc leadin and leadout with plenty of length.
I also end up with the blobs in corners (with rad, and withouth) and some on straight lines
here is a pic of the blobs and the parameters

Have you adjusted either your acceleration or braking factor?
It could be too much power, too tight of a rad in the lead in, dynamic factor too low. What is the focus on the head?
RE: blobs of slag on stainless 11gauge
focus is at 6mm
I have played with the acceleration / braking factor - not much has changed,
I tried a straight lead in and the blobs are much smaller but still present.

The pulse size decreased then increased. I repeated the process when I found the smallest pulse hole by stepping the focus by a smaller #. I ended up with a focus position of 60, now this is with a nozzle height of .7mm
According to my manual .7mm above is equal to 7 ticks on the cutting head focus ring.
When I'm cutting 11 gauge stainless with a hk15 nozzle I have my focus set to 2 full revolutions, or 120
so 120 – 7 (.7mm nozzle height) – 53 (head focus position) = 60, which is equal to 6mm, The manual says one turn on the decimal scale corresponds to a variation in height of 6mm ie 1 unit corresponds to 2/10mm
