Hello!
I have D4V2.5 on the way (D4V2 with KR4 driver) and can't find the info on what level out of 150 does the top of the regulated range (5A) correspond to.
For FW3A that is 130, which corresponds to 2.8A, so for KR4 driver it should be somewhere in 130-150 range, I think.
From the config file for KR4 I see that the default for smooth ramp ceiling is 120, same as for D4V2; I want to set it up to the top of the regulated range. Or this is not advisable?
What's the reasoning for keeping the same default - safety?
Thanks!
Which version? E21A?
No, its pretty clear with E21A - it has no FET, so the top of 5A is level 150.
I ordered the one with SST-20 4000K, so it's regulated up to 5A, then it's combination with FET up to whatever amperage battery can supply.
cfg-noctigon-kr4.h says:
#define MAX_1x7135 120
This means 120/150 is the level you’re looking for. You can also count the leading zeros in PWM2_LEVELS. 
Thanks!
I'm not sufficiently familiar with the source yet :) but I see the logic.
