General Info

1. Precautions

Handling and usage precautions

Warning: ALWAYS Power DOWN and switch OFF before disconnecting STEPPER MOTORS These boards go bang !

2. Sample Configurations

2.1. Blue PCB

 sample configuration for TB6560T3-V5 3 Axis board
 upload:tb6560_v5.gz
 also 
 upload:TB6560.tar.gz 
 revised and updated feb 2013 with thanks to awes
 includes EN and relay set for spindle 
 no limit switches or estop required , this is a base startup configuration 

any problems let me know in this forum thread and i will keep this updated with additional configurations as we come across them http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=49&id=23737

2.2. Configuration troubleshooting

The pin configuration instructions I got with the board were incorrect. So were the ones I found on the net. My board came with a cover which showed the pin settings.

upload:SAVEBASE-3-Axis-CNC-Stepper-Motor-Driver-TB6560-Box-Set-LCD-Display-Handle-Controller.jpg

So in this case:

Pin 2 - X dir

Pin 3 - X Step

Pin 4 - Y dir

Pin 5 - Y step

Pin 6 - Z dir

Pin 7 - Z setp

I set everything else to unused. I was able to test each axis in Stepperconf and they moved as they should, but the machine wouldn't budge when I ran linuxCNC and loaded up some gcode. I went back and added

Pin 1 - Amplifier enable

and everything worked.

3. Moding the Blue Board

3.1. 1th and Easy Step

 Change the Capatitor on the bottom it is Easy even as it is SMD  there is nothing arrond
 there is a 1000pf on the Board change it to 150pf (SMD1206) and get so 100times more feqency (400khz)

3.2. 2nd Step lots of soldering

 Change all Fr304-307 Recivier to Ultrafast UF5401-5408 ones DO201 Types
 No matter what Diodes on your Board are, 3A Ultra Fast ones are Needet  (16 cent eatch reichelt.de -> UF 5408)   
 this will meat the internel diodes,and save the circuit,the UF Diodes are a 1000 times faster then the Fr ones. 
  The Board will give you,with the first and the second modification, at 25k latency 10000steps per Second, SAVE without a loss,Timing same as L297.
  so it is almost good to invest about 5USD into the parts and some 1hr of work.
