MKS CD current amplifier

2pcs*MKS CD

2pcs*4pin cable

Description

42 motor-driver of 3D printer on the market is that the direct primary IC connect  to motor driver IC, the current consumed by each interface will not exceed 2MA.

The MKS Gen motherboard  that we design has signal port  ,which can   output  the signal from motor driver .We suggest using 4988, 8825 etc.  motor driver .

Generally, what 57/86 stepper driver inputs, is  the optical coupling isolation, mainly to  prevent from interference. Each motor driver  has 3 inputs. EN enable port controls motor switch.

PUL pulse port  controls the movement of the motor position or speed, DIR direction interface controls movement direction of the motor.

The driver current of general optical coupling interfaces is around 10MA, one  driver actuates  one motor.

One  driver consumes  most of 30MA control current,  after X, Y, Z, E  connect to four general 57/86 motor driver that will need  100MA current   at work .

It is easy to burn the 3Dprinter IC control board if build connection  directly but for not  enlarge current.

MKS CD expansion board can adjust the flow control signal, to avoid motor drive with optical isolation generate press  on  main IC, therefore , Ramps1.4, MKS Gen and other main board with five large motor drive can  operate  completely without pressure.

Insert MKS CD directly into the driver slot, leads the control signal from the above white card port . Please note the direction of the socket.
