Micro-tramming Adjustment?

[adamfenn28 (Adam Fenn)]

Where are the tramming adjustment on the Elite machine? My spindle is a little bit out of square with my wasteboard and I can feel small ridges in the wasteboard after flattening. I’d love to adjust that to be spot on.

Thanks!

Front to back ridges, i don’t know, maybe they want you to loosen one screw then tighten the opposite side, and do to both sides…

But the left to right, just loosen 3 screw on the z20, and put a square down tighten another screw and use a tram mechanism of your choice

The product description says “Micro-tramming”, which makes me think there’s a more elegant method for making these adjustments. I’d like to use a dial indicator on a tramming arm to really get it spot on. I think that will require more precise adjustment than loosing the screws, moving it manually (coarsely) and then re-tightening the screws.

Tramming - Front To Back

There are a few methods to tram your machine. Loosening some z mount bolts, using 123 blocks, tram arms, folded pieces of tin foil, are all methods that can have acceptable outcomes. Left to right tram is relatively easy to correct. Front to back is a bit harder. There is a unique benefit of buying a Onefinity CNC machine is that every Onefinity machine has built in front to back tramming bolts on the X axis. These allow for tilt of the z slider front to back. There are 4 bolts on each foo…

I think left to right the only thing to do is what i saud.
Put a square up to it and you’ll get it pretty close then fine tune from there

Hey Adam,

the tramming front to back of the Z assembly can be done either this way:

• Tramming - Front To Back

or like some forum members described, by loosening the Z assembly bolts and placing some layers of small aluminium foil pieces between the Z assembly and the X carriage block.

The tramming of left to right of Z assembly can be done this way:

• Tramming your Onefinity and Laying out a gridline on your Spoilboard – Youtube

By the way, the official tramming the router thread of this forum, that you could have found with the search function, is:

To my knowledge (please correct me if I’m wrong) there is no special Elite tramming:

I used 123 blocks under the z after loosening the bolts, then i switched to the dial indicators, it was within .002 thou frt to back left to right. I never could micro tram it. I ended up loosening the x axis blocks and i think it was .010 shims in my case to get it right. I buy amazon feeler gauges and just use them for shimming, blocks and tramming arms shown below. Slow and tedious process, butwell worth it. The problem I have now is I’m reluctant to ever move the z axis

Thanks for your help. This is what I needed. I searched the Elite forum, since I was looking for information on the Elite’s micro tramming feature. I didn’t realize it wasn’t specific to the Elite.

Hey Adam,

which is not surprising, they didn’t advertize the Onefinity Original Series with it, it was just to be found in the forum.

Thanks CNC people. I’m squared away now.
