Versaprobe

Hello,
im using qtdragon and i have trouble when trying to measure the tool height after i manually change the tool.

this is my process:
i start the machine and after i insert a tool (i zero the tool (G54) on the top of my workpiece) and i enter in the MDI field "T6 M6" so its moving to my individual tool change position and after i have to hit "ok" when i changed the new tool. So after this step the machine is moving to the automatic tool measure position what i configure. Its going down and hit the switch then coming up a bit and then with a slower speed going down again to measure.
After this i get a message about my "probe height", "block height", and "touch result". Usually i get 78mm for touch result.(same tool)

So after this when i try to zero my machine in MDI G54 g0 x0 y0 z0 its not going completly down. In G54 its everthying 0 but if i check the absolute coordinate, showing -78, so still 78mm missing what is the same value like the touch result.

I dont know how to solve this problem. I tried and i read a lot but i didnt find anything yet.

Ah and in the versa probe menu im struggeling to set the right "probe hit" and "block hit" hight.
I always measured with my tool inside. I read i have to calculate from down (from the table) so for example i measure with absolute coordinate and i touch the top and i read the abs coordinate (z -->  -140). My maximum z travel is 240. So basically i made 240-140 and the result i gave in versa probe "block hit". then with the "probe hight" i made the same but with different result.

thank you if you read all and i hope someone can light me up.
 

Sounds as if you have the same or similar problem as I and a few others.

You can see the thread  Inconsistent values from Versaprobe  and see if that's what you are encountering.

The probe height and block height are read-only and set based on 3d probe and tool touch off values.

 

so the versaprobe i can use only with the 3d probe correctly?
