How the controllers work...

The controller consists of a main control box and optional operator control panel.  In special purpose applications, custom firmware can be stored in Eprom or Flash memory. In profile cutting applications, the TekMOV firmware is used for control, and permits the operator to select jobs to cut, adjust speeds, jog the position of the machine, set origins etc. from the control panel on the machine. 

  • The jobs which the machine will cut are stored as files on a PC, and are sent to the controller when needed via the TEKMOV "DNC" (Direct Numerical Control) plot spooling program during cutting.
  • The  number of jobs that can be stored is limited only by the hard disk space on the computer.
  • The plot files are made in Industry Standard HPGL - ll language, which is supported by all leading software programs.  This rich control language contains commands needed to fully control all aspects of work done in profile cutting, including 3D profiling.
  • The firmware of the controller is configured by the TEKMOV Windows '95-98  Plot Spooling program, and stored in Flash Memory.  All aspects of the configuration such as resolutions, speeds, accelerations relay switching etc. are set from the user friendly setup menus on the host computer. 

The firmware has features to support the specific needs of each type of profile cutting machine.  Click the links below to see details on features for each type of profile cutting machine.

Controller Hardware Features
Large Graphic LCD Screen, Backlit for easy viewing in bad lighting conditions.
Membrane Key Switches sealed from harsh environments
5 Speed joystick for ease of positioning, gives much better controllability than push buttons.
Firmware is stored in Flash Eprom, for easy updating.
New versions of firmware can be sent via email, floppy diskette or retrieved from FTP site.
5 User Defined Relays
RS-232 Serial link between computer and machine eliminates need for special interface cards
Graphics / DNC link Host Computer can be up to 200 meters from the machine with the use of inexpensive serial line driver / isolator cards
TekMOV Controller Firmware Features
Easy to Learn
Online Help gives the operators and technicians access to the entire Owners Manual on screen.
Open Architecture system, using Industry Standard HPGL 2 and G Code Instruction Set
2D, 21/2D, and 3D plot files fully supported
3D Profiling Software allows both AutoCarve and sweep-pass style 3D profiling
Interactive Plot Spooler (DNC Link) allows you to store as many cutting jobs as you like on your graphics computer, and sends them to the controller when needed
100% error free DNC ( Direct Numerical Control ) style communications link
Plot files saved on Disk. Plotting a file from the graphics program to the hard disk
saves download time, and frees up the program to continue working without delay
Job Storage capacity limited only by hard disk space
When the job is being cut, it is sent to the controller transparently in the background
while other applications are running
Multiple machines can be controlled from one host computer
Units can be set up as mm or Inches
Motion Error Detection stops motion when following error of servos exceeds user specified set point. This safeguards against troubles caused by dull toolbits, stalled spindles, crashing into clamps cutting too fast etc. Saves material
Multiple Origins, up to 8 Origins can be stored on the system, allowing quick changeover to different jigs for production work
Origin Lock prevents Operators inadvertently changing origin during operation
Tool Offset Support so that pen and spindle or multiple spindles can cut from same origin
Digitizing Support for tracing objects on the table
Diagnostics Features
Comprehensive On-Board-Diagnostics allows the encoders, amplifiers, overtravel switches and relays, serial communication, to be tested one at a time for easy machine commissioning and maintenance
Easy Plot File Diagnosis. The plot file language is industry standard HPGL,
and can be imported to graphics programs such as Cadlink, and viewed
Machine Control Features
Homing sequence during power-up establishes the reference origin of the machine
Homing Sequence on Power up allows software squaring of dual drive gantry
Crashproof System Can't jog out of bounds
Jogging override during homing allows manual override to speed up initialization process
Job Origin is stored on Hard disk, allowing job restart after power failure. Automatic Power Failure Recovery.
Ultimate Jogging Control with user definable High and Low Speed ranges, 1/10 speed scaling function for accurate positioning
X and Y Axis can be jogged together or one at a time
X and Y Axis Job origin can be set together or one at a time
Spindle Position Readout on Operator Console allows you to know where the spindle is during jogging
2 decimal place position readout on Z axis for precise depth control
User Defined Park Location allows gantry to be moved out of the way for loading and unloading with the press of one button
On-The-Fly XY Cutting Speed can be adjusted while cutting.
Speed can be locked after adjustment, or free to read next speed command
Z Axis speed can be adjusted
Rapid Plunge Z Axis above material
Job can be paused and resumed during cutting
Searching within a Job
Search Function allows re-cutting of shapes
Simply push Search button, and move from shape to shape with the joystick
The machine can search through a job so that when it is started,
it can continue from any desired point
- search by shape
- search by change of depth
- search by vector within a shape
- search by nearest point to spindle (Proximity Restart)
Job Management
Jobs are selected from Operator Interface, using Windows 95 Long Filename format
Job files can be stored in sub directories on the hard disk, making it easy to keep them organized
Jobs can be deleted from the Operator interface
Scrolling Job List sorts jobs by name or date, making for fast selection
Utilities
Job elapsed time is displayed, allowing job chargable time to be calculated easily
Spindle Operation Time is logged
Minor and Major Service Interval warnings shown on Operator Interface panel when timed out
User definable maintenance intervals - Operator is prompted to service machine
