    How to prepare photoplotter: 3.1 photoplotter software installation connect photoplotter with pc via usb cable supplied with the photoplotter. Usb connector is located on the back side of the photoplotter. The photoplotter does not need to be powered at this moment. Computer will detect new connecte...

    Auto/manual switch: position of auto/manual switch has impact against laser head behaviour. Auto ‐ laser head moves to its starting position (left side of the drum) manual ‐laser head moves 1 cm to the right only before first data plotting, check the auto/manual switch and set it to auto position. W...

    3.4 run photoplotter before you start plotting, make sure that drum is in its initial position (white arrow on the left side of the drum should be aligned with white arrow on the top of the left holder of the drum). After you prepared your data for plotting on connected pc using photoplotter softwar...

    Viewmate directory contains program viewmate. This program is made by pentalogix (lavenir) and is a free of charge addition to the photoplotter software. It allows to view gerber files and to convert aperture files made in various pcb layout systems into one common file format (lavenir‘s format of a...

    Please note, that plotted image is in plotting area rotated by 270 degree (or –90 degree) and mirrored from some programming reasons. It means, x axis of the grey plotting area represents y axis of the film loaded in photoplotter (drum circumference), while y axis of the grey plotting area represent...

    Aperture files can have various formats, depending on software where it was created. This program uses lavenir‘s format as a standard. Beside lavenir‘s format (.Env) can this program read directly several other formats like cam350, isocam, gc‐cam – other formats must be converted to one of them. The...

    This method is used when there is a problem with aperture file conversion, or user does not have any aperture file generated by pcb design software, etc. Please note, that loaded aperture file is always tied to loaded and active associated gerber file. If gerber file is deleted (edit – delete board ...

    Gerb2bitmap commands overview: icons (from left): job job‐new starts a new plotting project – default situation when starting this program. Job‐open opens project file previously saved by command job‐save or save as. Job‐save /save as saves the current plotting project as it is in this program under...

    Tools‐panelize drill panelises drill for penalized film (only). The original excellon drill file (.Drl) has to be selected, as well as a new (panelised) drill file name has to be specified. If offset between panelised gerber data and panelised drill data is required, then this can be also specified....

    Program run_photo_usb this program controls connected photoplotter. Reads in bitmap files in fpf (proprietary photoplotter format) and standard bmp format, allows to calibrate photoplotter, pre‐set values for intensity of laser light and to set output parameters for plotting (plot resolution, negati...

    Selected file is loaded into program by ok button. Loading may take some time, depending on file size. If loaded file size is smaller than 14 mb, than its image is displayed, otherwise a message „file is too big to display, but plotting will be ok“ is displayed..

    Please note, that loaded image does not need to appear correctly in both axis, usually it is compressed in vertical direction to save space on the screen. You can drag bottom side of the dialog window to make image look right, but keep in mind, that this image is here displayed only for your informa...

    Setup ‐setup table opens dialog window for plotter setup – here it is possible to define adjusted drum diameter, measured inaccuracy values in both screw axis and drum rotation (circumference) directions as well as plot angle error used for an automatic correction. This setup is unique for each phot...

    Tools ‐generate test grid generates test plot file in shape of 10 mm line grid of specified dimensions (drum circumference and drum axis direction) and defined line thickness. This plot file will be automatically plotted with resolution 1016 dpi. Test plot can be used as a check plot, where plotter ...

    Tools – plot light bar will plot several small images in one row, where every image is plotted with different intensity of light according to preset parameters. Light intensity starts with value entered in field initial lighton the first image. Light intensity automatically increases with every next...

    How to work with program run_photo_usb: use file ‐open (or use f3) to read in an input file, either fpf or bmp. If you select fpf bitmap, image will be previewed as you browse across a list of fpf file in given directory. Also information on its resolution is displayed, as well as overall image size...

    5. Brief, step by step guide for photoplotter software: 5.1 load gerber file(s) into gerb2bitmap program. If you load gerber file in standard format (rs274‐d), it may be necessary to set parameters (units, data format, colours, ….). To load gerber data use job‐ import master gerber or an icon. Loade...

    5.4 load bitmap file (.Fpf) generated in program gerb2bmp into program run_photo_usb by command file‐open. Selected file is shown in preview window, displays the overall image dimension (note that displayed image dimension is 10 mm larger on all sides) and any user note created when bitmap file was ...

    A) if overall dimension in drum circumference direction is wrong linearly (all or almost all grids in this direction are little bit smaller or bigger), change drum diameter in run_photo_usb program under setup‐setup table. If dimension is smaller, decrease diameter value, if dimension is bigger, inc...
