4 Axis TB6560 CNC Stepper Motor Driver Board Controller

Note: this board is neither reprappable nor open source, so it's a bit questionable whether it

belongs into this Wiki.

Bogdan stuffed it into the wiki since he's using one or two, and he suggests folk may want to check them out. I think he bought his off of ebay. No one's going to stuff it into the "Official" Electronics any time soon.--Sebastien Bailard 06:07, 11 April 2011 (UTC)

?! Maybe this is for "discussion page" and not for here. Why is it important ifthe board is reprapable or not?! Are sanguino, arduino, pololu driver or any otherof many drivers we use reprappable ?!

Here we go anyways:

NOTE: This stepper driver board is HIGHLY experimental within the reprap community ( less than 3

known users, none 100% satisfied with their configuration yet)

NOTE: When I contacted ebay seller about the faulty driver board (they delayed sending me

replacement) he told he they had received 3 faulty boards at once and were asking which one is

mine

NOTE: During tests I managed to kill 3 different TB6560 drivers (one by just hooking scope to the

output)

NOTE: This board is closed source, which means we'll have oodles of trouble printing it. A reverse

engineered schematic of the 3 axis variant of these boards is available

You can get it on ebay

Users of this family of Chinese boards should be aware that many, if not all, apply power to the

TB6560 in completely the wrong order. The chip spec sheet calls for the 5V logic supply to be

applied and settled before the motor drive voltage is applied. There is a belief in some of the user

community that absence of the logic voltage allows the upper and lower MOSFETs within the

internal H-bridge to both be in a conductive mode simultaneously. There have also been reports

pointing out poor slew rate with some of the opto-isolators fitted to these boards leading to missed

steps and the incomplete isolation provided in that there is a common earth plane between the input

and output.

NOTE: If you want something more reliable, SOC Robotics also has a DB25 style breakout board

(MK4, MK4c, MK5) and TB6560 driver boards that may work in place of this China board with less

problems http://www.socrobotics.com

TIP: the model commonly used appears to be a HY-TB4DV-M.

The 'TB' means it uses the 6560 chip ( TA means the TA8435 chip, which is also used on a similar board). The '4' means the number of channels.The -M and -N boards have different physical layouts, and may be different revisions of the same basic design, not sure?

The pinount in the provided document was wrong (completely) so I traced the pcb for real values

and here they are:

You may find that the fourth stepper driver enable pin is not available on the DB25 connector. If so,

it is on the DB15 at pin 1.

ALTERNATE: In some revisions at least, the enable pin for the fourth driver/channel is *SHARED*

with the enable pin for the third channel ( assuming you wire them in the order XYZE, it means that

your Z and E drivers share their enable line ).

-Also i received aboard this week that had pin 17 inverted for y axis to be enabled. -james

villeneuve (edited 12/6/2010) - if you use a stepper board, be sure to test the configuration out

quickly with a parallel port program. my preference is to test with mach3, it is open source and easy

to configure in windows. it is however not open source. i would use emc2 to test it if you are in linux.

setup example for emc2 is here: http://makeyourbot.blogspot.com/2010/02/making-emc-do-printer-

dance.html mach3 free demo version here (full test but 500 gcode limit)

here:http://www.machsupport.com/downloads.php I am not associated with mach3, and only use it

here for reference. feel free to edit or remove mach3 comments if it is not appropriate. james

another issue, is people need to common both the electronics and the controller to a common gnd.

do this by having pin 25gnd, connect to arduino gnd.

DB15

Pin CNC

1 E-ENABLE

Note: The enable pin's are pulled high so if you do not drive them all drivers are enabled by default.

[ -> not necessarily true. i have found that i need to ensure that they are driven high/low whatever

state is enabled.

also in reprap firmware you need to make it non inverting enabled. reprap gen 3 is inverted for

enabled. these electronics are non inverted for enabled. (james villeneuve) 1/19/2011]

DIP Switches

Current Setting 1 2 Decay Mode Settings 3 4 MicroStep Settings 5 6

100% ON ON FAST ON ON 1 ON ON

75% ON OFF 25% ON OFF 1/2 ON OFF

50% OFF ON 50% OFF ON 1/8 OFF ON

25% OFF OFF SLOW OFF OFF 1/16 OFF OFF

The currently recommended settings for the DIP switches are:

X & Y axis: 25% Current, Slow Decay Mode, No Microstepping ( ie use Microstepping value of 1 )

ie: OFF,OFF,OFF,OFF,ON,ON.

Z: To-be-determined. Currently we believe the required power setting may need to be higher than

X& Ym, but we arent sure. No Microstepping. perhaps: OFF,ON,OFF,OFF,ON,ON.?

Extruder: To-be-determined. No Microstepping.

NOTES: You need to avoid microstepping unless you have the absolute latest firmware, because

with *lots* of microstepping interrupts on all axes, you will get packet loss on the USB-Serial Host

communications. For now, the fix is to avoid microstepping. It makes it easier to debug lost steps,

etc anyway.

Signal waveform and timing:

The attached image seems to imply that there is a requirement to have the "step" pin pulled low

while the direction pin undergoes a change. It also seems to imply that there should be a quiescient

period before and after the change labeled "2C". A is the pulse width, B is the inter-pulse width, and

'C' is the required quiensent time before and after a direction change. The minimum values for A, B,

and C are not known at this time, but may possibly be calculated experimentally. please update the

wiki page if you have more information on this.

I have been fiddeling around with the above driverboard and couldn't get it to work with Mach3.

After looking around on the web, I found out it should work with LinuxCNC.

The settings used for Mach3 are the best to use in LinuxCNC, but leave the "enable" pins out.

Pin 2 = Spindle on

Pin 1 = X direction

Pin 16 = X step

Pin 7 = Y direction

Pin 14 = Y step

Pin 6 = Z direction

Pin 3 = Z step

Pin 8 = A direction

Pin 9 = A step

(Been turning "reverse" on and of to see what this would do, in my case the leds start to burn but

the motor wouldn't run).

I have put all the microswitches on the driverboard to ON.

But I am still fighting with the speed setup of the steppermotors.

(If I have any news, I will post it here.)
