Thanks for the kind words. Unfortunately my controller has not yet risen from the dead. :(
I have now tried almost everything I can. The last resort would be desoldering the flash chip, externally programming it and then resoldering it. I don't think I can do that...

How can i create two folders in the controller just to put my two differents settings for two machines?

Well this is an interesting idea. I could in principle make an utility that checks the keypad on boot.
If one key is pressed, it loads the first config otherwise the other one.
Would that work for you? Of course I can only make it, when my controller ever decides to live again...

I read more back, so I just updated my controller for the first time.
From Ver: 2016-06-10-80 to your new version

It's all right, I'll try it soon. I had problems with G3 code earlier, I hope... not anymore .

Thank you very much for your advice and helpfulness.

Glad you found it useful :beer:
I hope your problems will be fixed now.

old Zozo:
Unfortunately I still have problem with my controller.

If I make a bigger diameter pocket (e.g. diameter 17mm), everything is right.
But when I mill smaller pocket (e.g. diameter 10mm), tool steps down on a stairs.
G-codes is right, of course. (see the photo)

Which parameter need I modify?

- minimum log radius of 4axis mode is 5mm (I think, it uses only 4th axis)
- time duration between DIR and PULSE 5000 ns ( written by manual of DM556D driver)
- feedrate not to high (X and Y600 mm/min, Z 50mm/min)
- acceleration 100m/s^2
- interpolation period 0.005 s - perhaps it is small? I don't know...

Part of G-codes of diameter 10mm pocket is here:

N405 X-31.5 Y13.
N410 G01 Z1. F50.
N415 Z-2.
N420 G03 X-33.5 I-1. F600.
N425 X-29. I2.25
N430 X-36. I-3.5
N435 X-29. I3.5
N440 G01 X-29.5 Z-1.95
N445 G00 Z5.
N450 X-31.5
N455 G01 Z-1. F50.
N460 Z-4.
N465 G03 X-33.5 I-1. F600.
N470 X-29. I2.25
N475 X-36. I-3.5
N480 X-29. I3.5
N485 G01 X-29.5 Z-3.95
N490 G00 Z5.
N495 X-31.5
N500 G01 Z-3. F50.
etc. (same as above, only Z steps down)

:( :( :(
Benedikt, I'm so sorry yours controller... I'm sure, you can fix it.
You know, God takes mistake, too. :)

PPRINT:
old Zozo....I am using the Leadshine Easy Servos on my rig....which says to use the 5000ns DIR/Pulse like your DM556D. I tried that setting and it sounded like a freight train crashing. I do not have the parameters in front of me right now....but I want to say I am closer to 500.

I have not tried interpolating a small bore yet to see if I am having similar problems. I will be working with the machine in the morning and will give that try.

I just read your code before I was going to hit post. I noticed you are using I,J,K for your arc moves. I was not able to get arcs to work predictably with anything other than R's. I hate using R for an arc move...but I will stick with it for now. Maybe here soon I can adjust my post to try all of the IJK combinations to see if it works for me.

old Zozo:
Hi Rob, thanks for your answer and help. I will try decrease duration between DIR and PULSE.

I've read about R type arcs somewhere, there was written, not to good idea to use it.
So I never tried.

old Zozo:
I tested again. Nothing changed. What I tried to change:

-time duration (Dir/Puls)
-interpolation period
-acceleration

I see in the display,
when the tool finished the spiral movement, Y axis steps minus 0.2 mm.
-but why?
This is the 0.2 mm stairs.

Could somebody runs my gcodes? Not machining, only in controller.

When gcodes run out, you need to see last coordinates.
Correct coordinates are : X-29.5 Y13

My controller has false values, X-29.5 and Y11.8 !

Thanks, Zoli
