Possible tram issue after flipping spindle mount on Shapeoko 5.1 Pro

Hey everyone,

I think I may have created a tram issue on my Shapeoko 5.1 Pro and wanted to get some advice before I go too far chasing the wrong problem.

I’ve been working with J Tech to develop a custom smoke boot for my laser setup. As part of that, I flipped the spindle mount 180° to make room for the design. Mechanically everything still mounts up and runs fine, and I did a quick test to confirm nothing was obviously off.

However, it just hit me that by flipping the mount, I likely lost whatever factory tram alignment I had since I don’t really have a precise way to reattach it in the exact same orientation relative to the X-axis.

Last night I started noticing some inconsistencies in my cuts/carving (slight unevenness that I hadn’t seen before), and now I’m wondering if that’s due to the spindle being out of tram.

So a few questions:

  • Is flipping the mount enough to realistically throw tram out on these machines?
  • What’s the best way to re-tram the spindle on the 5.1 Pro without specialized equipment?
  • Would you recommend a tramming arm/sweep indicator, or are there simpler reliable methods?
  • Anything specific to watch out for on this machine when adjusting?

Appreciate any guidance. I’m still dialing things in and trying to build good habits early.

Thanks!

Unless you’re looking for sub-thousandths tolerances, I think one of these is plenty good enough…

You can even make one by bending a rod, or a couple dowels & a stick of wood.

I use one of these.
