Wantai SS880 drivers with DB25-1205 BOB

01 Mar 2019 21:06 #127459 by hIGGI

I just got Wantai SS880 drivers, 86HBM80-1000-1 motors and DB25-1205 BOB

I wired it in and managed to get it turning in LinuxCNC.

Is there someone actually using this setup, and willing/able to provide best settings for both drivers, wiring and of course settings in linuxcnc configuration?

I am sure i will reach limits of the BOB and will eventually upgrade it to something more advance / faster (Mesa?), but for beginning, i would like to try setup i have now.

Plan is to use these motors in direct drive setup on RF45 clone benchtop milling machine, with double ballnut ballscrews (RM2005)

your bob is limited to

so best to go for stable is 2500 2500 5000 8000 in stepconf wizard
as on a BASE of 100000 Internal take your latency around 25000 up to max 150000

as on a Regular start tuning on 40 VEL 120ACC METRIC
go ut the ACC by 50 on a TEST movement 5mm +-
till it stals out
around 750 Shoudt be the MAX on 800Steps per mm
then set it to 550 ACC
and start Vel UP to the limit around 120mm/sec
reduce to 80 and you are a Fine working setup
