YES! thanks, i was flailing trying to find how to get that, have been using inkscape for a year or so on windows but never been able to cut direct. Thanks again.

oh the highs and the lows its nearly as good as charlie! my cutter is not doing anything, tried a few things i found online but no joy, found a test - write a plot file name it hpgl save it on the desktop and send it by >>> $ cat Desktop/hpgl > dev/ttyUSBO which returns>>> bash: /dev/ttyUSBO: Permission denied tried it with sudo but still the same ........any ideas?

Make sure your USB to serial cable is plugged in properly After you plug it in run dmesg

check for a line like this: FTDI USB Serial Device converter now attached to ttyUSB0 The USB device is numbered so they go ttyUSB0 ttyUSB1 ttyUSB2 etc You will probably need sudo and your cat command should work but you need a leading backslash before dev and make sure you are using a zero and not the capital letter O

sudo cat Desktop/hpgl > /dev/ttyUSB0

What actual cutter are you using - do you know the device name and model? The serial communications settings may need to be changed (baud rate, parity etc)

my cutter is a mimaki CG60SR assumed the baud rate is default 9600 but have sent an email to them as i cant find it in spec, also think i will need to chang it to HGPL as this seems to be standard but was going to try first with MKGL which is factory default. ran dmesg and got >>>>> a [12200.004360] ===>rtl8192se_link_change():ieee->iw_mode is 2 [12200.060339] =====>rtl8192_set_chan()====ch:1

WLAN_CAPABILITY_SHORT_PREAMBLE Which didnt seem to do anything. Im off to solfest till monday so if you think of anything over the week end let me know. And big thanks for your time.

so are you connecting to your cutter with a USB -> Serial cable or a Serial -> Serial cable? If its usb the device will be /dev/ttyUSB0 but if its serial then the device will be /dev/ttyS0 (probably - may be /dev/ttyS1) I don't see any USB cable connection messages in your dmesg - your wifi card is being a bit noisy :-)

Its USB to USB and I was the same - unable to see any refrence to usb port. The wi fi is fine working 100%, I was going to try install my printer thru the the USB conection to see if it throws up any errors. My USB pen drive works fine thru the usb socket btw.

So it the USB is not a serial connection but more like a USB printer connection. I think you need a linux driver for the cutter...and there doesn't seem to be one... Inkcut says it supports the CG-60ST - but it has parallel and serial connectors....in fact all the supported cutters have serial or printer connections....

thats a bit of a pain, so looks like my only option is to try a lap top with a serial or parallel port? or find a driver? how do drivers work would i need one built for Ubuntu to work with any generic HPGL plotter or does it need to be made for both Ubuntu and mimaki hardware. Have also looked at this but is usb>serial, this but is for 3d -GCode - also tux plot seems to be popular but i cant see anything about usb, serial etc.........
