Cut large file in 2 parts?

[wf2ste 11]

When I try and cut a very detailed file the plotter gets half way through then just goes crazy up and down the vinyl. Is there a way I can split it into two jobs?

Yes, you can split a file in two (or more) pieces. It's basically 'tiling'.

If lack of memory is the cause of the issue you mention, it could solve the problem.

 

Just know that you will have to make them separate files and align and connect them to install.

 

If you mean to 'continue' a cut with a second file, I don't know of a way to complete the first half of the

image (file "A") then have the plotter start from the end of that cut and run "file B" to complete the series.

 

It may help to flush the memory between cuts by turning the plotter off then back on.

Have you double checked that it's not a static issue? Often static can freak out your cutter too. Also a lot of members have ran serial ports to certain cutters to get better performance. I wouldn't automatically assume it's a memory issue (not saying it isn't)

Usually memory will cause it to completely stop in the middle of a cut wouldn't it? Erratic movements sounds more like static, or corrupted file (stray nodes).

My value cutters have done the same thing in the past.

If not static, and without knowing your cutter, or cable: be sure the com port on the computer is set to hardware. Then be sure the com port on your software is set to hardware. Both of these settings are in the same area as baud rate, etc. (these are recommendations for the MH series)

My opintion, your computer is sending file, overloading the memory in the cutter. (Flow control). When set to hardware you (i think) will hav bi directional communication ( best done thru RS232 and or keyspan adaptor). This way the file can stop being sent when memory is full- then continue. These machines can send signals back and forth to the software.

Example- in hardware setting - cutter sends RTS (request to send). Then the cutter says CTs (clear to send). The computer is the master end- the cutter is the slave end.

Here is a link IF this topic interests you Pretty dry LOL.

Sorry here are some more details on what I run with,

 

MT871 run with a serial to usb adapter (Not keyspan) on windows 8

 

I do have a keyspan but when I have used this in the past I was having touble cutting things right. I am as we speak testing the Keyspan again.

 

Are these settings ok or does the baud need to be different?

Update - I managed to cut the files with the keyspan, Thanks for all your help
