DDSCV1.1 3 and 4 axis offline motion controller

[Will_D]

So how is parameter #115 dealt with (I am beginning to think the manual is telling lies) ?

It is mentioned in the 2.1 manual here:
http://www.nvcnc.net/pdf/NVCNC_DDCSV2_EN.pdf

There are also a couple of new parameters there as well.

[/ranton] HOWEVER why in the name of Babbage does the version 2.1 manual still use screen shots of an ancient 1.1 version that does not even show the Machine co-ordinates? Are they taking the piss out of us!!

Ah thats better

Having read this thread from end to end (ignoring a lot of the ranting and raving) I have a serious question about tool probing.

I have seen the video showing probing working as expecetd (!!)

It is not working for me.

I have tried to understand the parameters involved:

Parameter #68 Has 3 value 0 Disabled, 1: Mode 1, 2: Mode 2. Anyone have a definition of what these mean?

Parameter #69 Thickness: Ok I understand this one (But I though there was a reference to the controller measuring the tool sensor height)

Parameter #70 Signal Level: Again OK

Parameter #71 Initial Tool Position: If set to 1 machine heads off to Machine Home (as set in MACH workspace) If set to 0 nothing happens in X and Y.

Params #72, 73, 74 Define offsets from the Machine Home if #71 == 1

Parameter #75 sets the retract distance after probing. Understood but as probing doesn't work ...

Todays experiment:

Fit a simple touch plate and wire it in.

Confirm that if #68 == 0 nothing happens.

Set #68 to 1 and 2 and see what happens!

In either mode 1 or 2 state, On starting the probe cycles, it descends slowly, touches the touch plate, pauses and then retracts in the Z+ direction very slowly and then it never stops!!

Totally different behavious to the video where after the contact and brief pause the tool quickly rises to the retract distance.

Please help what am I doing wrong?

So I have been looking at probe.nc as installed

Attached is the original version (with Chinese comments)

Unbelievably I managed to translate the Chinese!!

https://www.google.ie/search?q=chine...hrome&ie=UTF-8

Attatched is the English version

No wonder the spindle rise to infinity and beyond: "G91 G01 Z1000 F5"

@Boyan and Benedikt: Is this the same file as on your working system??

[Will_D]

As it was such fun translating the Chinese I decided to have a go at slib.nc.

If this is actually used by the controller (as I'm sure the probe.nc is used) then it shows that the controller can handle very sofisticate g-code and a simple sert of language constructions/data variables/trig functions/macro calls etc.

Attatched is the translation with a bit of re-formatting

Where you able to get the probe function to work?
It works for me until I clip on to the tool.
Just touching the 2 probe leads together seems to work, but when I clip either lead on the tool it just goes down and stops/binds up.

[Will_D]

No not yet!!

[Will_D]

oops this attachment attacher is crap compared to SMF

Thing this is the right one

Hey buddy.

Just an idea, as I've recently got my setup working along with the touch probe, but do you have the polarity of the touch probe wired up correctly?
From memory the ground pin needs to go to the croc clip which clips to your router bit and the positive to the isolated touch puck which sits on the material surface

If you have it the other way around, as the spindle is grounded, connecting a positive wire to it would confuse things.

Thanks for the reply.

I have tried with the probe wired both ways.

It worked with an earlier version of firmware, but I can't seem to get it to work with the Xmas version of the firmware I downloaded from MadModder. https://madmodder.net/index.php?acti...0;attach=39115.

From my understanding of the manual the probe signal is PROBE terminal to +12V-I.

I don't see how it can work that way with the +12V-I connected to the tool. (grounded out) But like I said, I've tried it both ways.

I have also tried PROBE to Ground. (didn't work)

The only way I see that it could work would be if tool was isolated from ground.

That right there is your answer!
The guy who is modifying the code has broken something and has not yet fixed it.
I can't see a version list with faults and fixes so you can know what is good in any given version, it's a Crap Shoot!
