DDSCV1.1 3 and 4 axis offline motion controller

[Will_D]

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?
