chinese TB6600 drivers

It looks quite promising, but I doubt I'll be getting many as for the 3Nm motors it's better to run them from 75V.

Virtually any modern square stepper will benefit from running at higher voltage.

When we did the X3 CNC conversion back in 2005 we used 2.2Nm, as these were the best we could get at the time and ran them at 72 volts using the 888 drivers set to 2.5 amps.

Real over kill but never had one driver go pop, didn't need a fan either as they never even got warm

What is needed is a source of the high voltage drivers at a reasonable price.

thanks for the input lads, think ill keep it to the recommended 42v then.

Jonathan, not sure if you checked out the link i posted but in the tests that were carried out, the other board examined was the rattm brand one you linked to. and to be honest the reason i chose to buy the haoyu board was due to that comparison

interesting that those tests were only done at 24v, i'd be pleasently surprised to see some sort of reliability at the 36v to 42v range

obviously these would never replace the higher voltage drivers but i see a real appeal for people with a low budget and or small machines (such as the tiny lathe i will be using these on).

a small update.

drivers arrived yesterday while i was away



interestingly, if you look at the picture with the label there is a distinct lack of the expected chinese language but rather a belgian label.
considering it only took 8 consecutive days to arrive (same day dispatch) i think its safe to say the seller has cohorts in belgium which certainly makes it more convenient.

packaging seems sufficient, each unit appears to be sealed in an anti-static bag then cushioned in bubble wrap inside a suitably sized box

no manual or any literature is included with these drives.
the silkscreen on the board is quite self explanatory and the ebay add seems to fill in any gaps.
only time will tell if an electronic simpleton such as myself can coax some life from these boards

now to wait for the breakout board to arrive...
