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.
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 ?
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! 🙂
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.
