chinese TB6600 drivers

[jonnydeen]

its been quite a while since ive been on the forum but im now getting back into the cnc swing of things

since there is a distinct lack of information regarding these cheapanese boards i thought i might as well start a thread on them.

in particular the haoyu brand board of which i have ordered 2 to test on a d&m/colne lathe.

for those not in the know the specs are as follows...

TB6600 Features (courtesy of the ebay advertisement)

Output current: IOUT = 5.0 A (absolute maximum ratings, peak, within 100ms) IOUT = 4.5 A (operating range, maximal value)
Packages: HZIP25-1.00F
Built-in input pull-down resistance: 100 kΩ (typ.)
Output monitor pins (ALERT): Maximum of IALERT = 1 mA
Output monitor pins (MO): Maximum of IMO = 1 mA
Equipped with reset and enable pins
Stand by function
Single power supply
Built-in thermal shutdown (TSD) circuit

sounds good for £16.14 a pop eh? but will it live up to expectation?

there is currently an interesting thread on cnczone in which one member has made an interesting camparison between this and another brand of cheapanese tb6600, it makes for some compelling reading

the boards ive ordered should be with me in the next 2 weeks so i shall keep this updated as things progress.

the main data i am most interested in is voltage capability, i plan on testing the units from 12v up to 45v in 5v increments measuring performance as i go

if anyone has any ideas for how or what to test then your welcome to chime in
