Removing the incremental encoder

Removing the scale

► Place the new scale on a clean work surface.

► Attach the double-sided adhesive tape to the back of the new scale. The surface to be fixed down

must be clean and free of grease.

1. Head plate - front view

2. Incremental encoder

3. 3 x fastening screws

► Loosen the three screws (3) fastening the incremen

tal encoder (2) of the X axis and carefully lift off the

incremental encoder.

► Temporarily fasten the incremental encoder in a suit

able position.

► Mark the original position (1) of the scale (2) with a

scribing iron. This ensures that the new scale can be

fixed in the exact position to the right and left end

stop.

CAUTION!

Do not damage the gantry.

Make sure that the gantry coating is not damaged.

► Carefully lever the scale upwards on one side with

the scriber and then gently extract the scale.

► Remove any adhesive residues with ethanol. The

surface to be fixed down must be clean and free of

grease.

NOTICE

Cover strip on scale

► A cover strip protects the front of the scale. Remove this cover strip AFTER installation.

Installing the scale

► Insert the new scale behind the head plate.

► Attach the new scale exactly to the lay-on edge on the gantry.

► Pull part of the cover strip off the adhesive strip and place the front end of the scale on the marked

position. The scale must be positioned at the lay-on edge.

► Now pull away the cover strip "bit by bit" and firmly fix the scale (to about halfway along the gantry).

► Move the head plate so that you can fix the rest of the scale.

► Press the scale down with a soft, clean cloth.

► Carefully pull off the cover strip.

► Use ethanol to wipe the scale and remove any adhesive residues or dirt.

► Fit the incremental encoder. This procedure is described in Chapter "Replacing the X Axis Incremen

tal Encoder".
