Rotary Delta Robot 4 axis

Are you sure your drives re in velocity speed mode? Alot of drives come default as step/dir.

You pins and inputs working? Hal configuration menu item. You can check your pins and ignals live.

If linuxcnc starts, dont worry about the LEDs on the card.

Yes I changed P01-01 to "02" P02-15...P02-17 to"00" to disable limitswitch errors. And P02-30 to "01" to Servo On.

mesaflash --device 5i25 --readhmid
What does it return?
How is the 5V side on the 7i77 powered ?

I looked at the manual and it looks like your not connected to analog ref gnd should be pin 44. .

7i77 aout => pin 42 delta servo
7i77 gnd => pin 44 delta servo analog input signal gnd

You have it connected to 13

Also you can try with battery.
