* When SPINDLE UNIT is connected :

Z Unit moves between the coordinate (0, 0,-2410) and (6096, 4064, 0) at the maximum speed by revolving

the Spindle.

* When SCAN UNIT is connected :

Z Unit starts sensing between the coordinate (0, 0,-2410) and (6096, 4064, 0).

< How to Check Firmware Version >

Firmware version can be checked by pressing the STANBY key for 5 seconds after turning on the machine.

LED blinks and indicate the version.

For example with ver.1.8, LED blinks slowly for 1 time and quickly for 8 times.

5 Loosen the two screws on the LEFT FRAME shown in the

picture, and find the position where the load is less than 0.5kg

(5N) by adjusting the ADJUSTMENT SCREW.

ADJUSTMENT SCREW

Tighten up the ADJUSTMENT SCREW.

Measure the load by pulling the Z UNIT with the TENSION

GAUGE (ST-001) as shown in the picture.

If the load is less than 500gf (5N), adjustment is not necessary.

If the load is more than 500gf (5N), repeat the step 5 and 6

until it becomes less than 500gf (5N).

Adjust the position of the RIGHT SHAFT by putting the FEELER GAUGE (ST-030) and make it parallel to

the LEFT SHAFT.

If the two Z SHAFTS are not parallel to each other, the load prevents the smooth movement of the Z SLIDER

and cause motor stall.

This adjustment is necessary to carry out after replacing the ASS'Y,BASE Z SLIDE.

Software Operating System Overview

Windows driver Windows This is necessary when sending data to MDX-20/15 from a

Windows-based program.

MODELA programs

The Windows versions of MODELA Player, MODELA 3D

DESIGN, and MODELA 3D TEXT cannot be set up separately.

For the Mac OS version, there is only MODELA Player.

MODELA PlayerWindows

Mac OS

Windows

This sets the required parameters for cutting solid objects and

sends the cutting data to MDX-20/15.

This can import not only solid objects created with 3D problems

from Roland DG, but also solid objects created using other

commercially available 3D programs via DXF or STL.

MODELA 3D DESIGN

This lets you choose a basic shape such as a cylinder or sphere,

and modify it to create a 3D object.

You can intuitively create solid objects with smooth curves.

You can use MDX-20/15 to cut solid objects and save data in

3D DXF files.

MODELA 3D TEXT Windows

This adds thickness to text to create 3D characters. It's also

possible to edit text to make it bold, italic, or the like. You can

put a box around text with just a single click - a handy feature

when making nameplates.

You can use MDX-20/15 to cut 3D text and save data in 3D

DXF files.

Virtual MODELA Windows

This simulates tool movement before performing cutting with

MDX-20/15.

You can use it to check the finished shape as well as things like

whether the cutting depth is suitable and how much time cutting

will take. This can reduce loss for cutting materials and time.

Dr. Engrave Windows

This is used to design plates and send the engraving data to MDX-

20/15.

You can make large numbers of plates with the same design

with high efficiency. You can use the TrueType fonts registered

in Windows as the font style for text. You can even make stroke

fonts from TrueType fonts.

Because you can the outline of an image and convert it to line

segments, it's also possible to include logos for companies or

organizations in the plates you make.

When performing surfacing, set the depth-direction reference point to the highest location on the workpiece.

At the MODELA Player [Options] menu, click [Layout ...].

The slanted-line area is the surfacing range.

Click [Start] to begin surfacing. When surfac-ing finishes, the plane that has been surfacedis set to the depth-direction reference point.

To change the surfacing range, deselect this.You can change the size by dragging the solidsquares around the slanted-line area. You canalso change the size by entering values in the[Width] and [Length] text boxes.

Enter the surfacing depth.This sets the depth from the depth referencepoint.
