Beginner: CNC Z-Probe

[GS76]

Hi all,

I require assistance with connecting the following CNC X-probe to KFlop/KStep.

Any assistance would be much appreciated.

Thank you.

Hi GS76,

From the wiki:

It shows a Konnect Input used but a KStep Opto Input could be used instead. See KStep's Optically isolated Inputs described here. Opto Anode would correspond to Konnect's Common0.

Thank you, Tom,

So in accordance with this link below, I could use "JP33" and the pin 8 and then choose an unused pin between 9 and 24. Is that correct?

How would I activate it with KMotion to set "0" in the Z-axis?

What c code can be used to assist with this operation?

Any assistance would be much appreciated.

Yes

There are many approaches to "set 0". Global offsets, Fixture offsets, Tool offsets, etc. It depends on how your machine is configured and what your work flow consists of. Will you be setting the Tool Length? Will you be setting the Stock origin? Top? Bottom?

The simplest might be to set the Z DRO to zero with (from KFLOPtoPCCmdExamples.c):

DoPCFloat(PC_COMM_SET_Z, 0.0);

Or to some offset value based on touch plate thickness or such.

Thank you Tom,

I will have a think about this, but I appreciate the information.

Would I include that c code in the initialisation c code?

Hi GS76,

No, you would create a separate C Program to perform the probe and set the z. Configure an MCode Action to execute/wait/sync the program. Then put the MCode into the GCode wherever you want to do a Probe Operation. Or you could configure a User Button Action to execute the program and push the button whenever you wish to do a probe.

Makes sense.

Thank you.
