I had a similar problem with the TB6600 drivers shutting down on me with voltages above 25vdc. And it was having an issue of drifting just a little each time with back and forth motion. I am replacing it with a drive very similar to the one you replaced yours with. Took me a long time to figure out what was causing the drift, I thought it was the software or settings. But after I fixed the random powering down of the tb6600 with a 35v 2000uf capacitor(one I had on hand, but you could probably use much lower capacitance) at the voltage input terminal of the drive. I eventually used a much smaller driver I had for the 2 amp motord to test the 4 amp motor and had no drifting issues at all. I later heard that this was a common problem with the tb6600 two trees brand, I wish I had known that before I wasted money on it, only 10$. But more so all the time I wasted diagnosing the issue.
I'm no CNC expert but personally I would have wanted to mount those drivers on a metal backing to draw away heat. The wooden "container" is effectively the opposite of a heat sink.
Inside the cheap tb6600 they use, at least on mine, terrible thermal solution with a tiny aluminum plate and a terrible thermal pad. I would have checked that out before buying the more expensive drivers. I replaced the pad with thermal paste and thermal epoxied the aluminum plate the the casing after sanding the paint off and haven’t had a problem.
I just had the same problem. the 6600s worked fine on 3 different aluminum cuts. Then I over powered them trying to cut some steel for the first time. Now the X and Y just randomly shut off after a couple minutes. Looks like I need to do the same upgrade.
Hey Brandon, thanks for the video! Any idea if those new drivers work well on a Workbee CNC kit machine too? I'm experiencing some issues using TB6600. Even a brand new driver shut down without a reason. It appears to be faulty. Thanks man! 🙂
The linked DM556T drivers are not available currently. I couldn't find any WhiteSheets for the either. That said Amazon instead are recommending " HQ-HQ Stepper Motor Driver,DM556 2-Phase Stepper Motor Driver 42/57 Stepping Motor Driver " at $25 each. Could these be an equally qualified replacement ?
Emm! What motor you were using with those TB6600 drivers? are those Nema 17? I'm guessing you tried to pull a tractor with motorcycle engine. Edit: forgot to ask what is the voltage you are using to drive those?
You could probably do it with an arduino and the GRBL software installed into it using UGS as the interface for controlling the motors, though it may only support 3 axis(x,y,z). But you may have to write your own program for it with maybe a serial input to the arduino for the "manual" controls.

I know, that was the plan; however they don't even get warm.I don't see a need for it.
Precisely and if they do get warm a simple 120mm fan on them will do the trick (cut a hole in the wood so the fan can blow on the heatsink).

Why would you mute the sound on second driver test
Why would you mount drivers heatsinks u against wall of enclosure?
Hi, Can I ask there are DM556 and DM556T which one is better ( or what deferent )
I have no issues with my TB6600 drivers running 425 ounce nema 23's with a 20v power supply

Im sure glad I did.

sounds like a short

Great, there goes my plans for the CNC lathe and plasma cutter. The $25 ones are lower amperage, looks like the closest alternative is the $65 ones.
Oh no :(
Hey dude what software you using marlin or something another?... Did you just swap tb6600 with new drivers without changing config in software?
Mach3
Had to update the steps, or calibrate. Otherwise no issue.
Can make a tutorial how to build CNC and it's controller with Ardunio
Muito bom parabéns 👏👏

So that's where THX got their intro sound from.
thats prerty funny
HI BRANDON HAVE YOU VIDEO TUTORIAL HOW YOU BUILT THIS CNC MACHINE
Somewhat - th-cam.com/video/tYsvz9_Pg3Y/w-d-xo.html
Was it a kit with rails and leadscrews?
No, by themselves.
I have seen them sold like that though.
Can you help me with wiring DM 556T? My cnc dont work ,can i send you pictures to look at if you have time?
yeah sure. Email is in my "about" section
@@BrandonsGarage ok , ty
I am sorry but there is no email adress ... pay pal and pantreon ist just in about section...
Is it possible to control 20 devices at once?
Each driver is for 1 motor
@@nikonastrougkakos159
It is also 20 motors, 20 drivers, I want to control all of them manually, running in reverse
You could probably do it with an arduino and the GRBL software installed into it using UGS as the interface for controlling the motors, though it may only support 3 axis(x,y,z). But you may have to write your own program for it with maybe a serial input to the arduino for the "manual" controls.
you said the motor is 200 ppr as most are, but the lowest setting on the 556 is 400 ppr, how did you set that up ?
just tell the software that it should give 400 ppr..
(with the drivers 400 ppr setting, the motor uses 1/2 microstepping)
Time to clean up the mess.
So you’re telling us X failed with no load!?
yes
What lead screws are better^
Start CNC and cheap drivers say "AIR RAID!!!!"
Pretty much!
You seem to be talking to your self
