lasershark 2.1 no galvo movement

<< < (3/3)

Macpod:
The 5v rail readings sound fine. I don't think I would bother with another computer. The lack of 12/-12v is concern. Try probing that again and if that still reads low perhaps it's time to consider sending it to me for further diagnostics (email me and we will set that up)

jpilarski:
I think I got it working. I rewired my power supply, amp/drivers, etc and it now moves just fine. Thanks for your help. I have another issues however. I am trying to work in a 3dsoftware package called rhino/grasshopper. I've made an interface that samples the onscreen geometry into points and formats the points for the laser shark into the proper string. I then send the formated strings via serial through a paired virtual com port. I use the following command to grab the streaming points COPY COM2 CON | lasershark_stdin.exe. This seems to work or at least the shark launches and in the cmd I see the strings but it doesn't move. We also tried the same process but with a udp sender and receiver but the same thing happens. There are no errors in the prompt and I can quit the command with cntrl-c as expected. Basically I need some means of realtime playback. Do you have any ideas or thoughts.

Macpod:
To keep discussions logically separated I'll respond to you in the other thread you created.
