1XD + DM556 driver

What is the optimal Timing settings for this combo for M569 line?
Works with std setting of 2.7 but want to see what others are using.

Any suggestions for following on my Big Delta

M566  (6000)  ; set maximum instantaneous speed changes (mm/min)
M203  (12000) ; set maximum speeds (mm/min)
M201  (5000)  ; set accelerations (mm/s^2)

M203 set to 27000 seems to be max = 450mm (more than enough for me)

So is there a rule of thumb how M566 and M201 should be set to optimize?

Rule of thumb is to keep jerk low and accelerations high.I would start with jerk 40 and acceleration 4000, then follow one of the many tuning guides out there to fine tune.

According to the DM556T manual that I found at https://www.omc-stepperonline.com/download/DM556T.pdf, the minimum direction setup time is 5us. So I suggest T2.5:2.5:5:0. This assumes that the DM556 has the same timing specifications as the DM556T.

PS - I just found a DM556 manual that also specifies 5us direction setup time.
