So I spent months trying to figure out why my machine was cutting along and every time it moved to another cut, the Z would creep up. My .75 cut would be a .69 cut by the end.
I research all the forums, make sure your belts are tight, make sure your pully set screws are in on the flat spot, level your table, skim your waste board. Been there done that. Then for some reason some one hinted at removing a spring from one side. Oh my gosh it was like heaven just opened up and it started cutting great.
So I have emailed Carbide and got a few answer but not on this issue about the spring. I wanted to bring it to every body attention to save you the pain I was having.
*Yes make sure your belts are tight,
*Yes make sure your pulley set screws are in with lock tight on the flat end of the motor. By the way I received mine with set screws falling out.
*Yes make sure your roller wheels are not spinning and giving good tension on the rails
*Yes have a good sharp bit, If you don’t and use an old one you may get some creep
So Question is:
I am using 1 spring at the moment, is the a problem using 1 spring?
Is there a solution from Carbite about this?
All I can think is the new spring coming with the Shapeoko are too strong and they need to get a lighter spring.
So I am opening the discussion up to the public. This about drove me made because of the Z creep. I was about to buy another CNC machine because this was driving me crazy.
Hopefully Carbide will see this and make comments.
Oh yea, I did a simple circle test, with 2 springs and 1 spring, let the picture speak for it self
