Hey Alex.
Just wanted to thank you for this post, as I was struggling to get my Huanyang VFD to run at the speed I am setting from Aspire.
I managed to get it turning on and off at the start and finish of a job all ok, but the speed setting didn't work and it just ran to max.
Connecting the DCM and ACM together via a simple wire fixed it, so thank you.

Not strange logic really (for once!) It makes sense if you think that some controllers have separate power supplies for analogue and digital outputs. For example, this allows you to use the DC output from the VFD to supply the analogue output circuitry in the controller. A lot of cheaper BOBs only have a 5V supply for the digital side of things and need an external supply of 12V or so for the analogue output. And after all, it just needs an extra wire to make it all work with a common ground! The info is on the circuit diagram, although it doesn't leap out at you and I don't think that there is anything specific about it in the HY manual text.

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??Last edited by Will_D; 07-02-2018 at 01:57 PM.
