My z axis plate had a small bent in the middle. I disassemble it and lay it down on a straight clean surface. I was able to clearly see the bent and the plate had a play from its one edge to the other because of the bent. Even checked it with a machinist square.
So i decided to make a new z axis plate more rigid without any bents. I visited a guy who has a water jet machine, took him my old z axis plate and told him to copy it.
Next day the new z plate was ready. More rigid and thicker by 2mm. I removed any rust from it and painted it silver. So here it is:
I replaced some m5 screws and put longer because the new plate is 2mm thicker. Now its better and i dont need to reinforce the sides of the plate(as i was going to do). Previous plate was playing back and forth if i was putting some force with my hand when it was on the SO3. The new one is hardly moving by hand. What do you think about it?
I hope to get more accuracy and better results with the new one.
