    I bought some from this guy:

    http://stores.ebay.de/Markus-Mechatr...QQftidZ2QQtZkm

    They aren't listed for the moment but you could ask if he can still deliver.

    Regards,

    Hi,

    where can get he PCB to build the board ?

    I have 2 TB6560 here.

    Is a test video or picture available ?

    Best regards
    Chris

    Default My boards

    Here's a picture of my DIY version, it's a double sided PCB.

    I couldn't find an easy way to design the PCB with decent size power tracks so I had to choose between a nice design with connectors etc. or something that should work, I did choose the second option and came up with a very small PCB with connectors for the power input but soldered wires for the motor connections directly on the board.
    I also had to slip the PCB between the pins of the chip.

    These have been used on 3 machines and they work very well, even at 2,5 Amp output only a small heatsink is needed, no active cooling like almost every other chip needs.

    There's also a German guy who made a design, here's the link:

    Luc.

    Hi Luc,

    i know the german guy and i have contact via e-mail.

    The german version is not finished yet. He have some problems.

    Your design is very simple, that´s what i need.

    Is ist possible to get 3 PCB´s of your version ?

    Do you habe a part-list ?

    Thanks a lot.

    Bye

    Hi,

    there are 2 versions of "my design".
    The first one has jumpers for all options (torque and decay control), these have been removed on the lastest version.

    I still have one problem: on the first version the motor is noisy (hissing) and completely silent on the second version, I don't know why:
    PCB design, the different type of current sense resistors I used or the removed option jumpers.

    I don't have pcb's of the second version but have a few of the first one.

    I really need some time to investigate the noise disappearence by swapping components.

    Which motors do you have, output current required? Also wich power supply do you intend to use?

    My design is really simple but needs an optically isolated BOB (designed my own matching these drivers :-) ).

    Are you in a hurry? : I will make a new batch of the second version in the near future but can't say when.

    Regards,
    Luc.

    Hi,

    thanks for the answer.

    I can wait and will check the thread in the next time.

    Bye

    Hi all,
    Good jobs, any news of the latest version?
    1) Does Tb6560AHQ microstepper drive with any step error?
    2) Can Tb6560AHQ work without back emf dumping diode?

    I'm looking forward to your reply.

    Thanks,
    khoo

    Default The Data Sheet shows built in diodes

    The TB6560 data sheet shows built in free-wheeling diodes. It doesn't say if the external diodes are needed or not. Diodes are cheap. I think I would add them just to be safe.

    Cheers,

    Gridley

    I have used the smaller 2Amp parts TA8435 for years on my X1 CNC conversion. No re wheeling diodes needed, parts hardly get hot, motors get hotter. I also have motor hissing on the TA8435 controller but only in the Z axis motor? Very ugly design, all hardwired on vero board no pcb design.

    Just got my 1st prototypes of new opto isolated TB6560HQ quad PCB.
    Made the mistake of designing in SMD current feedback resistors.
    I think I will use though hole resistors for production units.

    Designs are quad versions of my single PCBs, 1.5Amp A3983 and 3Amp TB6560 micro steppers. The A3983 pcb will plug onto the propeller prototype PCB to drive the 17 size baby mill.

    Going to use the Quad TB6560 for a 23 size router design.

    I still have jumpers on mine, need to use them for real to find out what settings work best. Still need a few more parts before I can test these boards. Should know in a week or so how may changes will be needed before designing for production.

    I am open for suggestions.

    Regards

    Finally found some time to continue, I made some new PCB's a while back and used 2 different styles of wirewound resistors. And the hissing is back.

    I just replaced them with the "non hissing ones" without changing anything else and it's dead silent.

    So I need to find non-inductive ones, a quich search at different suppliers wasn't succesfull, they are either too big (3W) or SMD ones wich are just underrated.
    Anyone knows a good supplier?

    You are talking about the newer A version wich can do 1/16 microstepping, I didn't use this one yet.
    I don't have a good setup to test for step error, external diodes are not needed, they are sometimes used on some types of chips to take these currents out of them and thus reduce the chip's heat.
    The TB has a real low RDS and also uses synchronous rectification, these require minimal heatsincking.

    Why is SMD a mistake? Or can't you find the correct value and wattage?

    Luc.
