Stepper driver board TB6560-3V2

Mach3 compatible (parallel port) control board

labeled TB6560-3V2 and has no other identifying labels.

  • allows setting of microstepping in 1, 1/2, 1/8, 1/16 by dip switches on each of A B C
  • allows current configuration by dip switch on each of A B C
  • Has 3 x Toshiba TB6560AH0 under the fan/heatsink

  • DIRC - P7
  • CLKD - P8
  • DIRD - P9
  • CLKE - P16
  • DIRE - P17
  • EN - P1

Limit switches/EStop

  • CCOM
  • L10
  • L11
  • L12
  • L13

Port5

  • Gnd
  • En
  • CW
  • CW
  • 5V

Note: not sure if EN here is in or out as doesn't appear to be an output linked to EN - P1 on the parallel port

-------------

Inputs A-C each have their own TB6560 output

Input E is passed out to 'Port 5' breakout which is 5V and isolated for power and probably signals as well..

not sure what happens to Input D...

Moto1 is passed to the relay..

Assume EN is global enable

Limits switches are linked through to P10-13
