I have send you a PM.

Hello,
it has been a long time since my last post, I didn't have the spare time required.
There are still some boards and components available.
PM doesn't work so please contact me using the...
Upgraded TB6600 ????
The TB6600 is rated at 5A max, this one at 4A = 20% downgrade in my book.
It has a completely different chip, the housing of this one is not designed for heat dissipation.
...
Sorry wrong answer. Didn't notice the other replies...
Those could be remarked THB6064H's, these have seperate OSC input's for each channel, one of the decay mode pins is used for an osc input. This could explain why the motor turns strange, actually on...
The schematic is there since the beginning and proves the bad design quality.
Those 330K are useless indeed, shows how well the designer did read the datasheet...
Removing these is difficult...
The schematic for the N2 board is attached at post 5 of this thread and it doesn't have a 74xx14, only transistors.
The N6 looks similar to the N2, you could use my schematic as a guide.
I can only find this info:

Looks like it are 210 oz-in (pag 8).
The 5A/10A would indicate that it are 8 wire motors which can be used in parallel or...
1: This is a problem with your BOB or wiring, the drive should be disabled if the enable input is activated, but can't remember if I checked this.
2: The N2 board is the one I have tested here and...
Agree, I misunderstood because you replied this:
to tinky1233 (I'm probably not the only one who did).
You are using the drive at 24V and 2.5A if I read correct?
This is only 1/3th of the...
Think you made the wrong decision by buying the chinese, they do have inferior components as you said: the electrolytic capacitors will heat up and die soon, open sided connectors, etc..
I think...
This measurement will give a good indication but not a 100% good/bad one.
It's best to do this with all mosfets removed, the shorted ones MUST be removed or the measurement is useless.
To remove...
I'm not sure that the driver chips will be bad, depends on the supply voltage used. Measuring the outputs with a DVM in diode setting might give an indication.
To be sure a scope is needed,...
You said some mosfets are shorted, check if these are shorted to the gate also (they alsmost certainly will be). There's a big chance that the IR chips are gone too.
I would remove all fet's and...
Reason are the stepper drivers.
See this thread: TB6600 drive from EBAY
Good decision...
The chip is quite hot at currents above 2.5Amp and some other components also heat up depending on the supply voltage.
Best solution is a small breeze from a fan to keep...
That are a lot of changes, there won't be much left of the original board.
The 30% torque reduction will indeed be too low for some machines, depends on leadscrew pitch. Better is to do like the...
High time for a quick update, Frie has shipped the board and I found a bit of time to look at it.
The schematic looks the same as the HY-DIV one but I can't verify without dismantling the board,...
The RPM's you are looking for are rather low, you only need that high voltage supply for torque at fast speeds. Your driver + supply setup should have plenty of torque at 60 RPM.
Had a quick...
Sorry for the late reply, family still has priority.
The description or the pictures in the link don't show much.
It could be that the circuitry is the same as the HY-DIV268 but there should be...
Do you have a link to that board? Can't find anything on Ebay with that description.
Strange, somebody told me that the new ones were correct.
1/4th should be SW5 off, SW4 and SW6 on.
You...
Is it HY-DIV186N or HY-DIV286N?
Is the wiring correct? It would be strange that all drives have that particular problem, unless there's a new design or manufacturing flaw in addition to those we...
@ James: I did in another thread but lacked time to reply with details.
@ Bogdanalex:
There's no datasheet for the motor,so it's difficult to give exact settings.
Simple method is to adjust the...
Sorry for the late reply.
The motor heat is caused by the incorrect current setting for the series connection,
20% decay will generate less heat than 80% but this will be marginal.
Did you try...
I can't find a real datasheet for these motors.
Looks like the current setting is to high for series connection.
It would be better to use the half-coil connection and keep the 1.5Amp current...
I can't receive Private Messages here, reason unknow, Admin says everything is fine.....
The email = contact link on my web site should work .
It has been tested recently and works, I usually...
A normal DVM isn't suited for these kind of measurements, they are spec'd for DC and low frequency (50-60Hz AC only).
You could use them to measure the current on the supply input and compare the...
I can't receive private messages here on the zone for an unknow reason.
Project isn't dead.
PM sent to you.
It's impossible to comment without schematics or measurements.
The above is from your first post and seems to indicate the chip temperature: the TB6600 will run a bit cooler in the same...
Looks like the chip is glued to the heatsink (no screws) and I don't see any screws or other fixations between the heatsink and PCB.
Would they really dare to sell a drive with the heatsink glued to...
