Tighten the Centerline Slides

Before You Begin

Safety: Stop the machine, follow the site lockout/tagout procedure, verify that hazardous energy is controlled, and release or secure stored mechanical and pneumatic energy before opening a panel, removing a guard, or adjusting components. Electrical work must be performed by a qualified technician.

Warning: Before entering the saw make sure you have engaged the emergency stop with the key and take it with you as well. Always lock out, tag out the machine during maintenance in accordance with all local and/or company policies.

The purpose of this article is to explain how to tighten the centerline slide enough so that vibration does not allow it to move during setup while allowing it to move during normal operation.

1. Tighten the set screw evenly 1/4 turn. This will add a little drag to the axis. Too tight and the axis cannot run properly. Manually move the centerline up and down a few times to confirm it does not stall while moving. If it stalls the bolts are too tight.

1. Run the saw for a few hours or up to a day.
2. Verify its properly tightened by going to the check screen and then choosing the “Axis Stats” button
3. To check for slipping look at the Rerun column. Compare the ratio of Rerun to the Setups column. Too many reruns indicate a slipping issue. (Ignore this for the carriage axis).

If the “Rerun” column is higher on one axis than the rest then it needs to be tightened more. See the image below.

Confirm the Result

After restoring the machine through the approved startup procedure, confirm that the position or count changes in the correct direction, returns consistently, and reaches the commanded value without an encoder, calibration, or overrun warning.

If the issue remains, record the exact on-screen message, affected component, indicator-light state, and the last change made. Provide those details to Enventek Technical Support; do not repeatedly recalibrate or replace parts without identifying the cause.
