This has probably been discussed before but....Just added 4 more z axis roller guides to my PRT, 1 1/2" above and below the standard locations as found in the new PRT's- The machine is now much quieter, the Z movement more precise and now have no waterlines when cutting 1 3/4 material multiple pass. This is great bang for the buck and takes only a couple of hours to do - would recommend this mod to anyone with and older machine.
