Finally figured out how to set the M569 V so I'm going to test out:
; Stealthchop2
M569 P0 S1 D3 V78 ; Drive 0 goes backwards
M569 P1 S0 D3 V78 ; Drive 1 goes backwards
M569 P2 S0 D3 V111 ; Drive 2 goes backwards
M569 P3 S0 D3 V45 ; Drive 3 (E0)
M569 P4 S0 D3 V45 ; Drive 4 (E1)
M569 P5 S0 D3 V45 ; Drive 5 (E2)
M569 P6 S0 D3 V45 ; Drive 6 (E3)
Drive 6 tpwmthrs 45 (40.6 mm/sec)
Drive 5 tpwmthrs 45 (40.6 mm/sec)
Drive 4 tpwmthrs 45 (40.6 mm/sec)
Drive 3 tpwmthrs 45 (40.6 mm/sec)
Drive 2 tpwmthrs 111 (16.9 mm/sec)
Drive 1 tpwmthrs 78 (120.2 mm/sec)
Drive 0 tpwmthrs 78 (120.2 mm/sec)
