here is a guide to help sort out probe setup with Acorn CNC12
Note: on the next CNC12 release the Acorn setup Wizard will automatically take care of all of this buy simply answering a few questions, but for now you have to answer the question here and fill in the parameter settings yourself.

1. Probe installed ?
a. If not, set parameter 11 to 0 or do nothing.
b. If so, what input is the probe installed on? Set parameter 11 to that input number.

2. What type of input is it?
a. If it closes when the probe is tripped then parameter 11 should be a positive value.
b. If it opens when the probe is tripped then parameter 11 should be a negative value.

3. Does the probe have a detect signal installed?
a. If it doesn’t, then set parameter 18 to 0.
b. If it does, what input is it installed on? Set parameter 18 to that input number.

4. What type of input is it?
a. If it closes when the probe is connected then parameter 18 should be a positive value.
b. If it opens when the probe is connected then parameter 18 should be a negative value.

5. Tool touch-off device installed?
a. If not, set parameter 44 to 0 or do nothing.
b. If so, what input is the tool touch-off device installed on? Set parameter 44 to that input.

6. What type of input is it?
a. If it closes when the tool touch-off device is tripped then parameter 44 should be a positive value.
b. If it opens when the tool touch-off device is tripped then parameter 44 should be a negative value.

7. Does the tool touch-off device have a detect signal installed?
a. If it doesn’t, then set parameter 257 to 0.
b. If it does, what input is it installed on? Set parameter 257 to that input.

8. What type of input is it?
a. If it closes when the tool touch-off device is connected then parameter 257 should be a positive value.
b. If it opens when the tool touch-off device is connected then parameter 257 should be a negative value.

9. Using tool touch-off device to set the Z Reference?
a. If not, then do nothing.
b. If so, then add 2 to parameter 43.

10. height of the tool touch-off automatically taken into account when measuring tools?
a. If not, then do nothing.
b. If so, then add 1 to parameter 43 value. And set parameter 71 to the height of the tool touch off device.

Note: Probe detect signal cannot be the same input as the tool touch-off device but that the probe tripped signal can be the same as the tool touch-off tripped signal as long as both signals are using the same NO or NC logic. Thanks.

Can you provide a picture and or a link to the manual?

This will add the tool info from Fusion360 onto the first line and the 2nd line does have the tool diameter and Tool Height Offset from the CNC12 Tool library so you can compare if the info matches.

The prompt in CNC12 looks like this:
