3D Printers / First test run

« on: July 28, 2018, 06:36:08 PM »

Hi,

I tried a test run today and faced some difficulties as follows:

1.  I tried to test the setup by piping the Lasershark_stdin_circlemaker.exe to Laseshark_stdin.exe but I get an abnormal movement of the galvos and after a couple of minutes the galvos are starting to heat up.

2.  Also, in the Lasershark_stdin_input_example.txt file, it's given the format of the input is

S=X,Y,A,B,C,INTL_A here the TTL controls are last two parameters but when I try to run input the png file and run the lasershark_stdin_displayimage.exe I get the X,Y,0,0,0,1 the last 3 parameters are same no matter what. Can you me some insight on how to achieve TTL control? the laser is always on and the laser being projected is different.

3. No control for C parameter, when I write the flag -c it says illegal parameter.

I am attaching photos for your reference, thank you

3D Printers / LaserShark Wiring Questions

« on: June 25, 2018, 05:53:54 PM »

Hi Guys,

I am new to SLA technology. I am quite comfortable with FDM and Gantry type 3D printers, but when it comes to Laser Galvo SLA I am finding it a bit difficult.

I recently purchased the LaserShark board from Jeff and I am ready to start my project on SLA 3D printer.

The Components I purchased are:
1. LaserShark DAC board
2. Laser Galvo 20kpps
3. Laser Module with Driver

I am not worried about the Z-axis motion of the bed. I am looking to generate the layers as of now as my first priority. If any other components are required to make this work, please provide me with some insights.

I am attaching the pictures below for your reference and this is just a temporary wiring to depict my understanding once I know its correct I will proceed with the further steps with proper fixing of wires and jacks.

Thanks
