So, I’ve read a thread on here about axis perpendicularity and have attempted to employ those methods of adjustment (loosening the bottom/tightening the top and vice versa) with the 2.5" screws to no avail. (Its also possible I’m not doing it correctly based on my interpretation of the post)
I’m included a couple photos: 1 of the scrap piece of ply I manually faced with a 1" bit and 2 photos of trying to show the variance of the router to the rails along the y axis (lower toward -y and/or higher toward +y).
The photo of the scrap shows the two halves. The whole piece was faced along the x axis. The right half only faced along the y axis (after the initial x axis operation).
Am I being too picky at this point given the nature of the machine and it’s makeup or is there something I can do to fix this?
EDIT: Should also mention I’m using the new burly 660 mount.
EDIT: Added another photo. Definitely not the bit as my 1/4" flat endmill has the same issues. =(
-You are using a giant bit and that magnifies the problem.
-I have a blurb in the FAQ’s, if you have issues use it for a bit to break it in, then take it apart and try again. I think everyone gets it the second time.
-You can shim the 660 mount (I use layers of tape) instead of adjusting the bolts.
-You are not showing any pictures of you actual build so I can look for any obvious errors.
Where do you suggest placing the tape/shim? Inside the collar of the tool holder or between the tool holder and mount?
Also, I’ve added a few photos of the build in case I missed something obvious. Not sure exactly what to show you pictures of at this point. (The router is out of the holder because I put tape inside the bottom collar and it snapped the the bottom mount - weird - , so I have to reprint)
Depends on how you need to move it. It is only effective on the machine side of the mount. Just have a good look at it and it should make sense. I also have a tool on thingiverse to make this easier.
The perpendicularity tester? Yeah, I printed/used it and it’s definitely showing the bits tilting forward (toward -Y).
So… in my case where the top of the 660 is leaning toward -y, the tape should go between the 660 tool holder and the tool holder mount or in between the tool holder mount and one of the z axis conduit pieces? I just want to clarify what you mean by machine side of the mount
