If you have a program that can slice a 3d model into layer images, you could make a script based off of using lasershark_stdin_displayimage.c.

Hi,

yes I have emailed them some days ago and they wrote back that Creation Workshop is not currently compatible with Lasershark.

That is a great pity.

Does anyone have any idea how I can use the board for a SLA printer without first having to teach myself programming. Or does anyone still have the Plugins for the old CW Versions? It would be a great help.

Thanks

I am unable to download these files.

Are these your files or someone else's? If the latter, where did you find these links?

Hi

1. Starting with the ascii interface (lasershark_stdin) is perfectly fine for prototyping, it was intended to allow an easy start for prototyping.
If you send X and Y values, yes, it will make the galvo motors move to those positions. You can read more about the lines that you must send by reviewing the lasershark_hostapp code.

Specifically:
lasershark_stdin_circlemaker
lasershark_stdin_displayimage

And perhaps most useful for learning the protocol:
lasershark_stdin_input_example.txt
This file will tell you the format of commands to send (i.e. how to set rates, move galvos, and turn lasers on/off)

2. The galvo amplifiers require differential analog signals. The differential input voltage provided is what designates what position the galvos move to. A differential value of -10v will make the galvo rotate to it's fullest extent in one direction and a differential value of 10v will make the galvo rotate to it's fullest extent in the other direction. A differential value of 0v will make it move to a centered position.
The amount of rotation will depend on how much you change the voltage from one point to another. In the case of the LaserShark there are 4096 "steps" divided in the case of your galvos by 30 degrees. This means each "step" under ideal circumstances will correspond with a 0.00732421875 degree change. Note that in reality you will never achieve this small/consistent an angle change due to various imperfections related to each component in any galvo system.

3. It will require you to develop software but yes? Others have already done this to varying degrees. Unfortunately their works are closed source :(

Can you please clarify your question? I'm not sure what you are asking for

hi jeffrey nelson

Thank you for your reply and you cleared my previous points related to lasershark board there are few more things i want to ask about the firmware and hardware of lasershark board and galvo amplifiers:-

1. i am making my own custom host application for my client for SLA uv printer by using
    uart interface(i know its slow soon ll update to better interface) for now and my question
    is if i send X&Y axis values to lasershark board will that make galvo motors move
    according to values ?

2. i am asking this question for my knowledge only the galvo i bought from ebay they dnt
    provide much information regarding there galvo amplifiers they dnt provide any manual
    for there amplifier so for beginners its very difficult to understand the concept of galvo
    amplifiers the only  information i know is galvo amplifiers take +5-5 to +10-10 analog
    input and its factory setting 15   but what type of  signals(sine wave,triangle
    wave,square wave..?) they take and how much degree or galvo shaft will move according
    the signal we will give to galvo amplifier how can we calculate this according the pulse ?

3. can i use lasershark board for sla uv printer ?

Hi VitoB,

Creation Workshop is software developed by another company (Envision Labs). If you go to their website (www.envisionlabs.com) it suggests everything has moved to a new home (and maybe company?) of DataTree3D.

Have you tried talking with this company?
