The latest version of the 4 axis driver board TA8435 for stepper motor

This one is with the heatsink and the parallel cable

 

Here are the comparison of the old version and this new version. We have done some modifications on this new board.

How to use the MACH3 software.

图1

Fig1: open the mach3 software , choose the mach3 MILL ---choose ok.

 

 

图2

Fig2: we deploy the mach3 software.

 

图3

Fig3: open the port and pin menu under  the config menu.

 

图4

Fig4:set the standard frenquency in the first circle , this data influence the speed of the motor , and then choose the definition in the second circle to set up the pin.

 

图5

 

Fig5：follow the circle in the figure to set the software.

 

 

 

 

 

 

 

 

图6

Fig6:choose the output signals , follow the circle in the figure to set .

 

 

 

 

 

 

 

 

 

 

图7

Fig7: choose ok and the open the G code that we need to run.

 

图8

 

图9

Fig8:after opening the G code , you will see the red reset , click it and then run the cyclestart.

If need the manuel control , you can use the TAB to control it .
