Hi Thanks again for your help. I now have power to stepper motors but they will not run, they sound stalled or trying to run to fast so do not rotate
Do you have any idea ??

Most likely happening because your motor tuning in mach3 is set for the Gecko drives and these cheaper TB-based drives cannot handle the same tuning setup. Try backing off the velocity and Acceleration by 50% and try again. When you have it working stable then slowly increase them one at a time until they start to stall again then back off again by 10%.
-use common sense, if you lack it, there is no software to help that.

Why'd you get the P, O, S, TB6600?.

Hope you didn't pay too much.
Should've saved yourself aggro and just gone with 542 or 556.
You get what you pay for.

As I've said numerous times before, TB6600 are OK drivers, yet you seem to want to say they're rubbish at every opportunity.
They are by no means a high performance driver, but they're a reasonable basic stepper driver.
It was the older TB6560 which was well known for failing, but that was mostly down to people trying to run them on too high a voltage. If you actually ran them within their operating voltage range, they were an OK driver.
Not every application needs maximum voltage or performance.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

Do you have a 12-24v power supply plugged into the middle 2 screw terminals on the right hand side?.
If not, that is your problem. Inputs are powered by this. Only the outputs use the 5v power.
They are 2 separate circuits.
Around a 2Amp supply should be plenty.
Missing out this power supply is a common problem.Last edited by dazp1976; 11-04-2022 at 05:03 PM.
