CNC Motor Drivers; TB6600 vs. DM556T

[@artisticmike]

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.

Why would you mute the sound on second driver test Why would you mount drivers heatsinks u against wall of enclosure?

[@bpushkin3457]

Hi, Can I ask there are DM556 and DM556T which one is better ( or what deferent )

[@rhiantaylor3446]

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.

[@BrandonsGarage]

I know, that was the plan; however they don't even get warm.I don't see a need for it.

[@thebeststooge]

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).

I have no issues with my TB6600 drivers running 425 ounce nema 23's with a 20v power supply

[@marklongenberger461]

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.

[@cani77]

Radiators have a function, stifling the airflow by placing them against a surface that stifles them is strange or curious. This test is conclusive. For compensate a bad installation : use larger (and more expensive) modules.

[@paulksycki]

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.

[@BrandonsGarage]

Im sure glad I did.

[@bobsort]

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?

[@overlycranked8674]

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 ?

[@BrandonsGarage]

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.

[@thecrazylooser7]

Oh no :(

[@francescomioli]

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! 🙂

[@joeygonzo]

sounds like a short

[@matejgalesic5982]

Hey dude what software you using marlin or something another?... Did you just swap tb6600 with new drivers without changing config in software?

[@BrandonsGarage]

Mach3 Had to update the steps, or calibrate. Otherwise no issue.

[@ThomasShue]

Was it a kit with rails and leadscrews?

[@BrandonsGarage]

No, by themselves. I have seen them sold like that though.

[@salehmohamed1981]

Is it possible to control 20 devices at once?

[@nikonastrougkakos159]

Each driver is for 1 motor

[@salehmohamed1981]

@@nikonastrougkakos159 It is also 20 motors, 20 drivers, I want to control all of them manually, running in reverse

[@artisticmike]

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.

[@Auslander86]

Can you help me with wiring DM 556T? My cnc dont work ,can i send you pictures to look at if you have time?

[@BrandonsGarage]

yeah sure. Email is in my "about" section

[@Auslander86]

[@Auslander86]

I am sorry but there is no email adress ... pay pal and pantreon ist just in about section...

[@madbrit5053]

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 ?

[@winandd8649]

just tell the software that it should give 400 ppr.. (with the drivers 400 ppr setting, the motor uses 1/2 microstepping)

[@JowfeStudio]

HI BRANDON HAVE YOU VIDEO TUTORIAL HOW YOU BUILT THIS CNC MACHINE

[@BrandonsGarage]

Somewhat - kzbin.info/www/bejne/qorWp61vlLWaabs

[@ivangamer8022]

What lead screws are better^

[@nikhilmuchandi214]

Can make a tutorial how to build CNC and it's controller with Ardunio

[@cognisant307]

So that's where THX got their intro sound from.

[@BrandonsGarage]

thats prerty funny

[@Artnovetor]

Muito bom parabéns 👏👏

[@3dtek678]

So you’re telling us X failed with no load!?

[@BrandonsGarage]

yes

[@ratbagley]

Time to clean up the mess.

[@gsshopprojects1772]

Start CNC and cheap drivers say "AIR RAID!!!!"

[@BrandonsGarage]

Pretty much!
