Hi,  
I was trying to find the solution in any way, that’s why I also tried to use all of the baseplate surfaces and all of the bolts surfaces. It didn’t work and I forgot to turn back to the only surfaces that are touching eachother before sending it here, sorry.  
The problem is, that even with that change it doesn’t work. I was looking through the forum to find similar problems and I found one ([Reaction forces - #5 by Gunnar](https://prepomax.discourse.group/t/reaction-forces/1631/5)) but it didn’t work out for me. The forces still don’t appear as they should and I don’t know why.  
The updated file: [Baseplate\_connection.pmx](https://prepomax.discourse.group/uploads/short-url/63Yw5gTsImzJBjquMXG8aoFsjyz.pmx) (6.6 MB)  
Thank you for trying to help me.
