2 01 General information about SW 1.1SW SETUP AND INSTALLATION 1) To start using the updated screen set Purelogic THC Control 2.0, it is necessary to install the latest updated versions of plug-ins THC ( or higher + PLCM ( or higher. The latest plug-in versions are always available for downloading at Important To avoid problems with compatibility and cutting parameters, it is not recommended to use version PLCM with version THC or higher. PLCM can be used with versions lower than THC For detailed description of the plug-in installation procedure see operation manuals of the respective devices. 2) After installation of the above mentioned versions of plug-ins and connection of devices it is necessary to load Mach3 with new preset profile PLTHC.xml and screen set (file PLTHC.set in root folder of installed Mach3) and enable plug-in THC in settings Mach3 ([Config] -> [Config Plugins]), then restart Mach3 (Fig. 1.1). If you use you own xml- profile in your work, then you can load the new screen set version into it using menu options [View] [Load Screens]. In this case before you start you need to manually copy all files with.m1s extension from folder %MACH3%\purelogic\ Mach3Macros\ to folder %MACH3%\macros\%PROFILENAME%\, where %MACH3% is the path to root folder Mach3 (by default C:\Mach3), %PROFILENAME% name of the profile you use (for example, PLPlasma). 3) Once plug-ins are installed successfully, menu Mach3 PlugIn Control will contain options «PLCM control» and «THC control». 8 (800)

3 THC Control 2.0. Plasma Cutting System Control Software It is necessary to select one of PLCM controllers connected to the system in PLCM control settings, and then to check and set the controller settings, if required (Fig. 1. 2). Fig Mach3 plug-in enable screen After setup of PLCM controller proceed accordingly with controller THC ([PlugIn Control] [THC Control]) (Fig. 1. 3). Rev

5 THC Control 2.0. Plasma Cutting System Control Software 1.2 THE MAIN CHANGES AFTER PREVIOUS VERSION 1) User interface has been reworked completely based on clients requests and touch input support. Now it is divided into four screens according to machine operator operating procedure logic: Screen 1 (Fig. 1. 4) is designed for preliminary preparation of the machine for operation coordinate system parameters setting, preparation of parking location, etc. Screen 2 (Fig. 1. 5) is used for setting the cutting parameters, depending on the material being used. Screen 3 (Fig. 1. 6) is designed for loading control program (Gcode) and for correcting it. Screen 4 (Fig. 1. 7) is designed for monitoring the machine operation during G-code execution. It can be used to promptly adjust the torch movement parameters and monitor G-code progress. 2) Now it is possible to set any point within the machine operation desk as a parking location. The torch can be moved to the parking location for replacement of consumable materials or blank. 3) Now it is possible to «set over» the operator s coordinate system to align it based on the nearest side of the sheet blank. 4) Now it is possible to immediately save cutting process settings from user interface. Not the user can conveniently operate settings not only in the plug-in window. 5) Now the values of all parameters present in the screen can be set individually for each process. 6) Now the values of parameters «Минимальная скорость для регулирования» («Minimum rate for adjustment») and «Скорость регулирования Z» («Rate for Z adjustment») are set not as percentage of the maximum feed rate value, but in m/min. Rev

8 7) Two new cutting modes using gas-oxygen torch are added: adjustment using THC Up/THC Down signals and adjustment using a stand-alone device controlling Z axis. 8) The ТНС plug-in interface has been reworked taking into account the introduced changes, now it is possible to search by process names. 1.3 FEATURES OF UPDATE If you have a library of cutting process settings used with the legacy version of screen set, then it is recommended to make a backup copy of PLPlasma.dat settings file from root folder Mach3 before the update. Once the update is installed, it is necessary to check and change settings of all cutting processes available in the library. Due to peculiarities of Mach3 architecture, values of some parameters may be lost with migration from the legacy screen set to the new one and vice versa (low adjustment limit, high adjustment limit, etc.). In addition, it will be necessary to change adjustment settings (see item 6 of updates). 02 Setup of processes When «Настройки» («Options») button is pressed, parameter library window opens (Fig. 2. 1), where you can fill in all cutting parameters and save them under a definite name. To select a particular cutting process, highlight it in the list and press «Выбрать» («Select») button, after which all parameters from this window will be copied into the main MACH3 window (window «Установка параметров реза» («Seting the cutting parameters»). Thus, all settings of cutting process are located in the same place. As in addition to plasma cutting mode which was available in the first version of the screen set the software 8 (800)

9 THC Control 2.0. Plasma Cutting System Control Software supports 2 new gas-oxygen cutting modes additionally, the operator shall set a particular type of cutting process for each of the parameter sets. The default process type is «Плазменная резка» («Plasma cutting»). The further text contains the full list of available cutting parameters for all three types of the process with brief explanation of their values. 2.1 PLASMA CUTTING The appearance of plasma cutting process settings is shown in Fig Cutting rate depends on metal type and parameters of equipment being used. It is set in mm/min. As a rule, the value of this parameter is set according to cutting table contained in the used equipment operator manual. Burning-through height: the required value of torch Z coordinate before ignition of the jet is set in mm. Burning-through dwell time: burning-through dwell time (in seconds) for which the torch will stay with burning jet over the material at «Высота прожига» (Burning-through) height is set in seconds. Important For correct operation of this option it is necessary to select the checkbox near «G04 Dwell in ms» option in menu Mach3 Config- >General Config. Operating height: height in millimetres to which the torch will move upon «Burning-through dwell time». Height of «Smart burning-through»: The «Умный прожиг» («Smart burning-through) option allows decreasing wear of consumable materials when plasma cutting mode is used by reducing contamination of the protective screen with molten metal spatter during sheet blank burning-through. The «Smart burning through» operating principle is based on the fact that the electric arc can elongate significantly if it has been ignited already, and no arc breaking occurs in this case. It is necessary to arrive at the burning-through location, descend to the required height and activate the plasma torch. Rev

Fig Plasma cutting process settings Once the arc ignites consistently, and plasma machine switches on Arc OK signal, the plasma torch may be somewhat lifted to a safer height, and wait for completion of burning-through. Then it is allowed to descend to the cutting height again. By this time there is a hole in the material already, and plasma torch blows all metal spatter through it downwards. It is difficult to ensure such a behaviour in Mach3 software due to the fact that the time of Z axis up and down movement during «Smart burning through» is unknown, so it is impossible to wait for the required burning-through time precisely. No additional setup of Mach3 or G-code generation programs is required for use of «Smart burningthrough» option. G-code remains unchanged. Only one additional entry field appears with the height of Smart burning-through specified in millimetres. 8 (800)

11 THC Control 2.0. Plasma Cutting System Control Software If this value is not equal to zero, then the controller will lift the plasma torch to the specified height once Arc OK signal appears. In this case it will record the burning-through time starting from Arc OK signal time. If the burning-through time is over during lifting, then lifting will be stopped, and G-code execution will resume. The Smart burningthrough option operation is illustrated in Fig Overlap processing height: the torch overlap processing height in mi llimetres (G00). Search rate: torch lowering rate during search of material. It is set in mm/min. Search radius: if an ignition is carried out at the distance les than specified radius from the latest material search location, then the current Z coordinate is considered to be correct, and no additional search is required (see Fig. 2 3). Ignition will be carried out without any metal search. This value may be set to zero so that to carry out search before each ignition. Nozzle height: the value which shall be assigned to coordinate Z immediately after the material search. If touch is performed by the nozzle, then it shall be zero value. If some other sensor is used, then, evidently, at actuation time the nozzle is at some height above metal, this height depending on the installed nozzle. This is the height which shall be specified in this field (se Fig. 2. 4). Desired voltage: Desired value of voltage in the arc shall be set in accordance with cutting tables contained in the used equipment operator manual. If zero value is specified as the desired voltage, then immediately after adjustment delay the controller records the current arc voltage and will maintain it till the end of cutting. Rev

12 Fig. 2.2 Operating principle of Smart Burning Fig. 2.3 Search radius Minimum adjustment rate: in Mach3 it is known as «AntiDive». It sets minimum required torch speed in XY plane to enable adjustment. As mentioned previously, Mach3 decelerates the torch in turns, which results in growth of arc voltage and, consequently, possible lowering of the torch. To avoid it, the minimum limit of speed at which adjustment will be performed is introduced. If the current speed drops below this threshold, adjustment will be locked until the torch accelerates again. 8 (800)

14 Minimum adjustment rate: in Mach3 it is known as «AntiDive». It sets minimum required torch speed in XY plane to enable adjustment. As mentioned previously, Mach3 decelerates the torch in turns, which results in growth of arc voltage and, consequently, possible lowering of the torch. To avoid it, the minimum limit of speed at which adjustment will be performed is introduced. If the current speed drops below this threshold, adjustment will be locked until the torch accelerates again. Important In the new screen set this parameter is set in mm/min, in legacy screen set it is set as percentage of maximum current feed rate (cutting rate) in XY plane. Low adjustment limit: minimum value of Z axis coordinates range during adjustment. High adjustment limit: maximum value of Z axis coordinates range during adjustment. Both parameters are set in mm. The parameter operation is illustrated in Fig Z adjustment rate: it is set in mm/min. Too high rate may result in omission of steps or axis jitter, while too low rate may result in slowness in surface monitoring. The parameter depends on material curvature and selected feed, so it is selected experimentally for each cutting mode. Important In the new screen set it is set in mm/min, and in the legacy one it is set as percentage of the maximum rate value Motor tuning on Z. Output voltage ratio: it is only used with LV input and sets the plasma machine output 8 (800)

For this screen set operation mode it is supposed that the user has implemented the following control diagram: Z axis is controlled by Mach3 software (through PLCM series movement controller or from LPT directly); Correction of position on Z axis with enabled adjustment is carried out via reading of UP and DOWN inputs (if UP input is active, then Mach3 sends command for moving the axis up, and if DOWN input is active, then the command for moving the axis down is sent. If the adjustment button is off, then UP/DOWN inputs are ignored). Movement along Z axis is only possible at active input ARC_OK (THC ON on tab Ports & Pins). To set up config, proceed as follows: Rev

16 1) On tab [Config]-[Ports&Pins]-[Output Signals] assign the preheating control output to Output3, and Z axis adjustment output to Output5. Specify the appropriate port and pins. 2) On tab [Config]-[Ports&Pins]-[Input Signals] enable inputs of signals «THC ON», «THC UP», «THC DOWN» and specify the respective port and pins (see Fig. 2. 7). The appearance of parameter library window in gas cutting mode with adjustable Z axis is illustrated in Fig Heating duration: The time necessary for preliminary heating of the metal to be cut before start of cutting, that is the time from heating flame valve opening till feed of cutting oxygen jet. Values of other parameters are described in item GAS CUTTING WITH STAND-ALONE AXIS Z MODULE IMPORTANT TO AVOID ACCIDENTS DURING GAS-OXYGEN CUTTING EQUIPMENT OPERATION, IT IS NECESSARY TO USE SAFETY HARDWARE (SAFETY GAS VALVES, DEVICES FOR CONTROLLING GAS-OXYGEN MIXTURE COMPOSITION IN IGNITION MODE, ETC.) For this screen set operation mode it is supposed that the user has implemented the following control diagram: Z axis control is assigned to an external controller (complete device which independently implements functions of maintaining a gap between the operating tool and the blank without involvement of Mach3); UP/DOWN inputs and THC ON (ARC OK) are not involved; 8 (800)

18 Mach3 Z axis can be controlled in «manual» mode using «Перемещение вверх» («Up Movement») and «Перемещение вниз» («Down Movement») outputs (once the button is pressed on the screen set, Mach3 activates the respective output. A stand-alone controller reads such an event and moves the axis until the button in the screen set is pressed again, and the input is deactivated). Pressing «Регулирование» («Adjustment») button activates the respective output, the stand-alone Z axis controller recognizes the event and switches over to maintaining the gap in automatic mode without involvement of Mach3. To use this mode, on tab [Config]- [Ports&Pins]-[Output Signals] activate the respective outputs Output4, Output6 and specify the port and pins (see Fig. 2. 9). The appearance of parameter library window in gas cutting mode with external Z axis is illustrated in Fig For detailed description of parameters see items 2. 1 and 2. 2 of this Manual. 03 Operation program start and stop display and control area This area is located at the top of the screen. It includes a group of cutting process controls (buttons, fields and indicators). The composition of the displayed controls depends on the selected cutting mode. 3.1 PLASMA CUTTING The appearance of the operation program start and stop display and control area in plasma cutting mode is shown in Fig (800)

[Поиск базы и обнуление координат] (Datum search and zeroing of coordinates) starting a macro searching zero values of machine coordinates. To use the macro, end sensors must be available on axes, and they must be set up in options of Mach3 ([Config] [Ports & Pins]). 4.2 «ПАРКОВКА» («PARKING») SCREEN AREA Parking is displacement of the torch according to coordinates preset by the operator. It is most often used for the torch maintenance (replacement of consumables, nozzle cleaning, blank replacement). Fig. 4 illustrates the appearance and composition of the parking area controls. 3.

25 THC Control 2.0. Plasma Cutting System Control Software 4.3 «ВЫРАВНИВАНИЕ СИСТЕМЫ КООРДИНАТ» («COORDINATE SYSTEM ALIGNMENT») FIELD If a sheet blank is located not in parallel with the operating coordinate system axis, the user may align the machine operator coordinate system based on one of the blank sides (Fig. 4. 4) in XY coordinate plane. The system is able to determine the necessary coordinate axes rotation angle based on two points located along a side of the blank. In this case the coordinate system will be aligned based on the coordinate system axis nearest to the blank side, i.e. the coordinate system will be rotated within ±45 of its initial position. The alignment procedure is described below: 1) Set zero alignment point, moving the torch in manual mode to the point nearest to the machine datum on the selected side of the sheet blank and pressing [Нулевая точка выравнивания] (Zero alignment point) button. 2) Move the torch to a point far from the machine datum on the same side of the sheet blank. The greater is the distance between the two points on the selected sheet side, the more precise will be the determined necessary coordinate system rotation angle. Press [Выравнивание системы координат] (Coordinate system alignment) button to calculate the coordinate system rotation angle and align the system. In this case the X and Y coordinate values will change their colour to red in the respective fields. 3) To cancel the coordinate system alignment on the sheet blank, press [Отмена выравнивания] (Cancel alignment) button. 4.4 FIELD «ВВОД G-КОДА» (G-CODE ENTRY) This screen area (Fig. 4. 5) contains a manual G-code entry line and [Ручное управление] (Manual control) button for enabling the manual torch movement mode using cursor keys (jogging mode).
