Dear gurus, I would like to ask for your advice. Which drivers would you recommend purchasing? Which ...

The tb6600 driver can be used with confidence, and we have a lot of users using it. If lost steps occurs during processing, change the pulse level polarity in ddcsv.

Thank you for your willingness to help Nikolay. I found a post on this forum, where Alessio upload ...

I know people who have a machine running these drivers.
And it works well. But the controller there is not DDCSV.
By the way, I was mistaken. These drivers are digital. But they do not have a connector for tuning through a computer.
But if there is a great desire, you can get everything to work.
You can try to conduct the last experiment, before they throw it away.
Step division 1/8. # 416 = 7000. There are two jumpers inside the driver, J1 and J3. J1 must be opened and J3 closed.
Parameters # 418- # 421 = LOW.
Disconnect the motors from the machine, put the disks on their shafts. The diameter of the disks is equal to the diameter of the motor housing. Disks can be made from anything.
For example, from plywood or plastic. On the disks and on the body you draw serifs. On them you will determine if the motor loses its steps.
Speed is not more than 5000 mm / min.
And you try to run test programs.
Based on the results, sign off.

Thank you for your willingness to help Nikolay. I found a post on this forum, where Alessio uploaded pictures of that driver and said that he couldn't start it at all. Thereby, I really do not feel like having "sex" with them

I would like to hear people's recommendations on which drivers work the best with the controller DDCSV2.1

I would be in your place, I bought a normal digital drivers (your drivers are analog).
They now cost very cheaply for Aliexpress.
But if you want to "sex" with those drivers that you have, you first need to understand what part is to blame for skipping steps. Drivers, motors or mechanics.
It is necessary to disconnect the motors from the machine.
If the steps are still lost, it is advisable to get somewhere known to the serviceable motor, which does not exactly lose steps and check with it.
If this does not help, you need to understand the steps are lost when changing direction, or while moving in one direction.
To do this, you need to create special test programs.
When you give this information - I'll tell you what to do next.

Dear gurus, I would like to ask for your advice. Which drivers would you recommend purchasing? Which ones will work properly without any extra dance with tambourines. I have some sort of noname 4A drivers on the TB6600 chip (you can find lots of those on eBay for £5-6) but I still cannot make those drivers work without skipping steps. Does anyone have experience in working with DM542 drivers? Please share your knowledge.

All of machine parts are second hand ; stepper motors (nema 34 with encoder) , vfd , screws +nuts , ...

Then take any Leadshine driver with the encoder.
Lichuan drivers are copies of Leadshine. Kind of like Adidas and Abibas :-)
You can take the driver without the encoder. The motor encoder is not necessary to connect.
Everything should work if the drivers are not defective.
Do not think about it that much.

Dear nikolay / ytliu
Please, I need your helps.I will order Leadshine HBS86H cloosed loop step drive ...

Your problem is that you think too much.
And you complicate the task too much.
You have an NC machine tool of an amateur class. Why do you need a stepper motor with an encoder?
Why such a powerful driver?
I do not know what country you are from. Maybe there you have all the millionaires and you just do not know where to spend money?
If I'm wrong and you are not a millionaire, buy cheap drivers, like DM556.
To him buy ordinary cheap stepper motors for 3 amperes.
Everything will work. I guarantee this.
Unless, of course, you do not sell defective parts :-)
If I'm not mistaken, and you're a millionaire, buy brushless servo motors.
They will be in all respects better than stepper motors with an encoder.

Dear nikolay / ytliu
Please, I need your helps.I will order Leadshine HBS86H cloosed loop step driver. Do you have any
experience for this driver? In the manual of driver, there are some technical notes. But, I don't want a problem like step lose. DDCSV 2.1 and HSB86H driver matching perfectly ?

-  power supply capacity? Which one is the good for the controller? In the table ;  60VDC 10mA  / 100VDC 16mA
-  In the manual, PUL/DIR notes: "Double pulse mode (CW/CCW) Software configuable" ? is it a problem for ddcsv 2.1? You are talking  a problem about CCW/CW.
-  R=0 if VCC=5 , I am not sure, Should I add resistor between controller-driver  or remove series resistor (101=100 ohm) form controller? or nothing.

I will be pleased if you help me

Looking forward to your results. In addition, I have completed the logic design, the test results ...

Excuse me Ytliu.
I confess, I doubted your ability to solve the problem.
But your abilities, as always, exceed all expectations.

In any case, I will bring the digital delay line to practical implementation.
If you, for whatever reason, fail, the digital delay line will be a temporary solution to the problem.
