Hi all,
here is the final result,
i'm not happy at all about how i positioned the spindle switch! :bang: It should be much lower.
Never mind, the next will be much better than this one......... :ddb:

Question:

Has anyone used and calibrated the Backlash parameters #437 to #445?

If so do they work?

Someone in another forum try, he said they works great for him, but honestly i do not use them as i do not have backlash in my axis.

You may not be able to measure it, but trust me you DO have backlash  :lol:

I do agree with you, but as i changed the ballscrew for the C0 grade, even if my backlash is 0.004 (and should be less as the ballscrews are pre-charged) i cannot measure it as my caliper do only 0,01..... so i do not have backlash

Hum.........
After all of the uploading, downloading and all the rest of the jazz, I seem to have lost the parameters that I setup the DDCSV1 with.....

I have at least one image of the firmware contents, does anyone know which file contains the actual settings (like steps per mm, etc) and how - if possible - I can use this to replace the default numbers.

Otherwise I will have to start again from zero which is *not* my Sunday evening plan.... :(

The file is called "settings"  and you have to reset all the parameters,  as is not a text file,  so.....  Take your time and input all parameters again,  and then, I strongly recommend you to make a copy of it...

I think there is a textfile called UserVar that is supposed to be another way of entering parameters, how the hell it works or what the format is I have no Idea. this is from the information Sheet, such as it is.

3.4.1Parameter loading method

 "This file is a text file with an expanded-name of set. The users can modify all the parameter
and all the parameter can be modified in the parameter list. We will provide a demo of set file
and the client can only modify the corresponding item in this demo. Pay special attention that
each parameter item has the only corresponding parameter mark. This parameter mark canít be
modified or deleted."

 hope this is of some use
Backup, then Backup the Backup then Backup again

We never figured out how this was supposed to work. Unfortunately. I might think about writing a quick and ready program for altering the settings file on a PC. Might be worth it. Especially if it would give some contextual help and possibly some converters. I was just thinking, why not a PHP program so people could use it online  :scratch:

Why not?  A php would be better I think

A PHP program would be an excellent idea - massively less tedious than 'step, step, step, step, ' 'enter', 'up arrow', 'enter' for each yes/no choice!

Great, so PHP it'll be.
I'll work on it when I find some spare time.

Hi All and welcome,
I'm a​n old beginner from Hu​n​gary. ​ :)

I just have this ​controller, version: 2016-06-10-80NOR

I would like use it with TB6560 3ax. stepper driver, but I can't find, where can I decrease
500KHz (200ns) pulse to 30KHz (33.333ns)  due to no this option anymore.

How could I solve this problem?

Thanks for your help.

Hi, and welcome,
First of everything have a look at this one, is very interesting about your driverr


http://www.glyn.de/data/glyn/media/doc/TB6560AHQ-E_en_090324.pdf


This can give you an idea of your stepper controller to start.


The only parameter you can adjust on the controller, version: 2016-06-10-80NOR is in the setting page, line 416 "delay between step and direction" "xxxxxxns"
Hope that can help a bit
Regards

Old Zozo,
a question for you, where did you get the 33.333 conversion of the 30KHz in ns(p) p=period?
Because my conversion is totally different, so maybe something is wrong? Or the decimal point is in the wrong place?
For the avoid of doubt, check this one:
https://www.unitjuggler.com/convert-frequency-from-kHz-to-ns(p).html?val=200
Anyway, the division is 1/Freq,   EXP: 1/8000000(8MHz)=125ns
so, 30 KHz are 33333.3333ns. am i wrong?
Regards

Hi Merlin, you are right, of course.   I was wrong, I wrote microsec, no ns  :bang:

Thanks.  (Hungarians uses decimal point this way: 33.333,333   English uses 33333.333)

I looked at my TB6560 driver, the OSC capacitor a small SMD part, unfortunately I can't change it.
I'll try some parameter later yet.

I'm not happier. I tried everything.
Stepper motors are very loud, they runs irregular, noisily, jarring.
You can hear.

https://drive.google.com/file/d/0B92KqmQ4Au7naVRnSEU0M1BQQnc/view?usp=sharing

After 10 minutes motors are hot, with half current setting.
When they are standby,  all vacillate.

What I tried:

TB6560: http://www.osservatoriobassano.org/TCS2015/3%20Axis%20TB6560%203.5A%20Stepper%20Motor%20Driver%20Board%20Manual.pdf

-half, 1/8, 1/16 step
-decay mode slow to fast



DDCSV1.1: 
-time between DIR and Pulse  300 to 1500
-pulse signal LOW an HI

I have no more idea.
Perhaps software down-grade...

Hi,
I give you my opinion, but just take it as an advise, nothing more...
The controller board you are using is manifactured for a Mach3 use, as is using a parallel port, and is tuned for the latency and other problem that the parallel port connected to a PC have in real time running.
Your new controller is much much faster and have nothing to do with this board :palm:
You need to use separate stepper driver for each axis, and you can find them really cheap on ebay if you want to start with an entry model.
I would suggest you to buy a good one once and forever, so your system is then matched as it should be, quiet and running cool.
Then get rid of the parallel port once and forever, as this is the pourpouse to buy that kind of controller...
I will make a short video of mine running with digital stepper driver http://www.ebay.co.uk/itm/EU-Stock-4PCS-DM556D-Digital-Stepper-Motor-Driver-50VDC-5-6A-For-CNC-Router-/142190444856 (those are mine, but you dont need that much, you can find digital ones and much much cheaper.


Those one are perfect  http://www.ebay.co.uk/itm/CNC-2DM542-Microstep-Stepper-Motor-Driver-4-2A-Controller-24-48V-DC-Nema17-23-34/251117211299


i am happy with that and no missing steps or heating or noise, strong holding torque and auto-tuning firmware..... just have a look if you have time.
Once you have built the controller it will work even for future machines if you upgrade the chassis.
Any comment is fully apreciated as usual
Regards
