Shipping list(Per unit):
LV8729 * 1pc
heat sink with sticker * 1pc
Note: Please make sure the connecting direction is right, or it will probably burn the driver chip and controller board. Recommend to do a good job of cooling for the module.
Driver current algorithm and its adjustment:
1. Driver current algorithm: i=Vref/0.5, the default Vref about 0.4V, so the default current 0.8A, and maximum current 1.5A
2. Please DO NOT connect the motors when measuring the voltage, or it’s easy to burn the drive.
3. Please connect both the power supply and the USB for power when measuring the voltage.
4. Minor adjustment for potentiometer driver. Adjust it again after measurement to avoid burning driver by excessive current.
5. To increase the current by rotating the potentiometer clockwise slowly, and anticlockwise to reduce.

  2. S***e

    I have well received the order but it lacks a heatsink.

  3. Customer

    Timely delivery correct. The drivers work fine.

  4. A***r

    everything was fine. Shipping tooks from order to delivery 17days to germany.

  5. F***r

    a very good driver for 3d printer extruder. no more noise. and by adding the tmc2208 on x y z, the prinyer is very quiet.

  6. S***t

    Quick delivery. Thanks.

  7. E***l

    not tested yet but i hope they will work

  8. V***n

    Perfectly. Moskvu for 11 days. Workers. 3D printer now below herb, silent water.

  9. M***k

    Looks good not tested

  10. Y***a

    Thank you very much !

  11. C***o

    Perfect and good furniture state Drivers. It Took a little But arrived safely.

  12. V***n

    Super Service. For: there is no one radiator the driver of sets, connectors for drivers soldered but like the driver got in planting connectors. Bonus put ceramic screwdriver. The absence of a radiator very upset.

  13. N***a

    It look good but warning to most cheap cnc user. This step stick CANNOT replace old stepstick directly because it work at 1/128 step that all of cheap cnc/3d printer that use 8bit cpu cannot send pulse fast enough to operate it. So you have to remove some pin to make it work at 1/64.

  14. J***s

    Order received quickly, time to check is not present. If that would not confirm a review, but don’t think that, there will be something wrong.

  15. Customer

    Fast shipping and compliant

  16. E***v

    All OK, work. The driver is not very much, for Arduino better TMC

  17. C***M

    fast shipping (less than 1 week), well pack, with a screwdriver as gift. highly recommand that store.
