Nice work stimpy!

Just an FYI too..
You may have noticed that there is a new firmware (release V5). This came out to address an issue where if there are still samples present in the lasershark and the output is turned out before they are finished, they will not be cleared and may unintentionally be displayed when a new layer is being printed.

I suspect this update may cause issues with Creative Workshop due to an algorithm change however Steve should be able to quickly make a patch by reviewing my latest commits to the lasershark_3dp code.

Yeah already use latest firmware v5

Only problem we got is on win7 64bit.

There are some problems when we use the lasershark on win7 64bit the blanking is not working good i will put 2 links from movie made win7 64bit.
First link is with only connected the lasershark on the computer with win7 64bit.
Second link is with lasershark and webcam that is standing on with win7 64bit.

If it works fine with 32 and not 64, this is going to be a host-side issue vs a lasershark issue.

Hi Jeff, I am also testing Lasershark with CW and I am having some issues - artifacts during scanning.
In this video entire working area is being scanned and several times the galvos are performing some undesired movements - you can also hear it in the video:

During these issues the D1 LED goes brighter than usual.

Do you have any idea what might go wrong? Thank you for any help.

Hi Daniel,

Pardon the delay, I missed the board email message that said there was a new post.

D1 is the USR2 LED. This toggles on or off whenever a sample packet is received. If it remains off or appears "brighter" it is because the computer has momentarily stopped sending data to the LaserShark.

Debugging this is going to be extremely difficult due to the number of components involved.

A first step would be to identify if what you THINK is being sent to the LaserShark is correct. Has anyone analyzed the output of the scanning algorithm to determine if it is correct? Furthermore if you repeat the same scan, are the artifacts in the exact same spots?
