Introduction17IntroductionDMC software created by MB "Cognitio" working under trademark Direct Machining Control isdedicated to be a single control center for your laser machine. You can design your motion path forpositioning stages and galvo scanners, control laser parameters as well as other devices like powermeters, motorized objective lens turrets, I/Os, serial port devices and others.All this is done without using G-code. And by skipping the G-code conversion step, everything canbe done quickly and visually.You are welcome to blast your creativity with DMC, because adapting, fixing, changing and creatingthings is easier than ever.Main features of DMC:Direct hardware controlWYSIWYG (What You See Is What You Get) window for machining preview.Support for both: positioning stages and galvo scanners.Support for stitching (infinite field of view) with galvo scanners and stages.Import of CAD files (DXF, DWG, STL, Gerber).Special GUI for a specific task-optimized machine.Ability to write plug-ins to support your hardware. 2015 Direct Machining Control

16DMC User ManualSelect a command with left mouse click on it.Move command up/down or delete it with buttons on the top of Recipe Window.Some of commands act as a parent commands and have child commands belonging to them (e.g.Cycle is a parent command and all commands included in the cycle are child commands to Cycle).Parent command has a triangle symbol to it, which allows to expand or subtract view of childcommands. Child commands are also indented to right. There might be several layers of Parent Child relations, with one child command being parent command for others.To make command a child command, move it up/down below the parent command until it has rightindent.3.3Command WindowSettings of the selected command are displayed in this window.Com m and w indow w ith tabs 2015 Direct Machining Control

224DMC User ManualConfiguration and Set UpDMC configuration is available at File Settings.4.1Positioning StagesTo configure positioning stages, firstly, enable and configure appropriate motion controller (A3200from Aerotech or ACS).Positioning stages can be configured in File Settings Hardware Positioning Stages.Positioning Stages Settings WindowYou can enable axis by checking Enable box.Generic settings for stages:Axis letter (name).Acceleration Mode allows to select whether stage acceleration cure will be linear (evenacceleration) or sinusoidal (slower start and end with steeper increase of acceleration in themiddle).Max acceleration for jump sets maximum acceleration for jump (no laser firing) mode in mm/s 2Default acceleration for jump sets a default jump acceleration value which is used for jumpmotions.Max speed sets maximum available speed for that axis in mm/s. If higher value is entered in therecipe an error message will be provided.Default jump speed sets a default value in recipes for jump speed in mm/s.Min/Max position sets the limits of the axis travel. both positions can be positive, negative or zero.Value is set in mm. 2015 Direct Machining Control

Configuration and Set Up23Invert axis direction inverts coordinate direction comparing to hardware settings. E.g. if in controllersettings coordinate increases when moving from left to right, with Invert direction checked it willincrease moving right to left.Home offset sets a new Home position. After homing axes go to a location defined by offset andsets it as 0;0 coordinates.Relative motion before homing moves stages a defined distance before homing action.Home priority sets homing priority for each axis. Axes will be homed starting with priority no. 1and then moving down the list. In some configurations different homing priorities are necessary toavoid crashes, e.g. lowering Z axis to not damage focusing lens. 2015 Direct Machining Control

Configuration and Set Up25SettingsController Type: set the controller you are using (RTC4/5 or virtual controller).RTC Card Number: select number of RTC card if more than one is used.Laser Mode: set the laser mode.Field Settings:o SWAP XY Axes, changes X axis to Y and vice versa.o Invert X, Y direction inverts axis direction (changes positive values to negative and vice versa)o bits/mm sets your field size / resolution.o Size X,Y, sets field size in X and Y directions.o Offset X,Y, offsets 0;0 position by set values.o Scale X,Y,o Field Rotation, rotates field around 0;0 position.Select Lens Correction File sets a lens correction file to use for this scanner.Default Speed:o Default Mark Speed sets a default motion speed when laser is on.o Default Jump Speed sets default motion speed when laser is off.Delays. See Controller card manual for galvo scanner delay information.VarioSCAN Settingso Check Enable VarioSCAN to enable it.o Min Coordinate sets a minimum VarioSCAN coordinate.o Max Coordinate sets a maximum VarioSCAN coordinate.o Invert Z Direction inverts axis direction for VarioSCAN (changes positive values to negative andvice versa).RTC5 sets specific RTC5 settings. 2015 Direct Machining Control

Select camera device from drop-down menu. If your camera is not found, check if it is not used bysome other software. DMC supports all cameras with DirectShow drivers and cameras from IDS(uEye), Basler, Mightex manufacturers.3. Enter camera name, that will be seen in the commands and Ribbon menu.4. Select whether to see a cross in the view center.5. Click Connect to connect to camera.Next go to Calibration tab to setup Calibration settings:1. Check camera view, and mark Flip and Rotate checkboxes to adjust camera view to match yourcoordinate system.2. If distance from camera center to laser is known enter it in Camera to Laser Offset.3. If View Size (mm per pixel) parameters are known enter them as well.4. If Camera to Laser Offset and View Size parameters are not known, follow calibration procedure. 2015 Direct Machining Control

Main Principles633Main PrinciplesRecipe creation in DMC is both: feature rich and simple at the same time.For simple recipes, such as common marking tasks, you can either import CAD file or draw objectsby hand with simple geometrical tools like circle, line, arc, rectangle. Each tool when used becomesa command in Recipe window. For better precision you can set parameters such as position andsize in Command window.Motion paths (trajectories) for stages and galvoscanners are created w ith Geom etry toolsFor more advanced tasks recipe may be created in a high level logical programming way with RecipeFlow commands. You can import CAD files or add geometrical objects, set parameters for each.You can also easily repeat the path by adding cycle command. For more flexibility and automationVariables can be used for values of the parameters, that can be changed during the flow of therecipe.Add Recipe Flow com m ands to create com plex and flexible recipesAll the commands in the recipe are executed in the order top to down.Some of commands act as a parent commands and have child commands belonging to them (e.g.Cycle is a parent command and all commands included in the cycle are child commands to Cycle).Parent command has a triangle symbol to it, which allows to expand or subtract view of childcommands. Child commands are also indented to right. There might be several layers of Parent Child relations, with one child command being parent command for others. 2015 Direct Machining Control
