Wiring a Corner finder and height control

[Ger21]

Thanks firetrappe fpr helping to sort this out. I think we've got all our answers now.

But shouldn't it rise 3 mm. To get the plate out and then drop 19 mm to Z 0 when goto zero is pressed or am I grasping this thing all wrong?

(16+3=19. Go to zero -19 in the positive direction)

No, the Clearance Plane is not an offset amount. It's the Z level where all rapids are performed at, in Work Coordinates. The manual explains in a little more detail on what it should be set to (Page 11). It MUST be a larger value than the plate thickness. If your fixed plate is higher than your movable plate, the Clearance plane needs to be higher than that plate as well.

for starters my plate thickness is not 16mm! i cut a 5mm pocket where it sits on the corner of the workpiece!! so in actual fact it is 11mm!!

And now we know why the Material Offset was not set correctly.

Strangely enough that worked!

Not strange at all had you followed the instructions in the manual.

however, when i press "go to zero" the tool plunges into the material around 0.2mm

Because your plate is probably 10.8mm thick. Do you have a caliper or micrometer you can measure it with? Also, with such a large plate, it's important that it's perfectly flat, and is lying on a perfectly flat surface.

shall i use the "offset" to counter act that?

NO!!! If your plate thickness value is set correctly, your Z zero will be set correctly. Trust me, this works for thousands of other users.

Read the manual for an explanation of what the Material Offset can be used for.
