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 jeffrey nelson

my name is Jaspreet i am interested in one of your product "lasershark board". i am working on one of my client project which is "stereolithography uv printer" i know little about galvo motor through which we can achieve speed for SLA uv printer i been searching online and reading blogs and lot of people prefer your board to control galvo motors because its open source n custom.

 For starting to understand galvos i purchased cheap Chinese galvo motors which comes with laser projector (10k to 20k speed & 8bit or 12bit DAC) please check attached pics and files and i have few questions regarding lasershark board :

Questions:

1.is it possible lasershark board can control these Chinese galvo motor and galvo drive ?

2.do i need separate lasershark board for X&Y motor or one board can handle both X&Y
   motors?

3. is this board is just plug n play wires according to settings of hardware and software or i
   need to do some kind of programming to setup for galvo motors only not for stepper
   motors ?

4.do you have any windows application to run your lasershark board ?

5.according to your website new version of lasershark board 2.1a is available in your store,
   do u have its latest firmware 2.1a opensource also ? in case of any custom programming
   needed in future ?

6.can you tell me what else galvo motor  brands can lasershark board support accept
   Chinese laser galvos for example brands like (cambridgetechnology,SCANLAB,Thorlabs )?
   please suggest less expensive galvo motor n drive.

7. do u have any firmware which follow XY2-100 protocol ?

this is the link for chinese laser projector i bought from ebay incase link required :
