That is all you need to do! Forget about the 24V or 5V, it is not used for limited switch u...

Re: Samples from T9 DSP controller

FAQ: http://www.lightobject.info/viewforum.php?f=75 You don't want to run the XY without testing the limit switches at all. Usually how I did was to move the laser head to the center of gantry then power it up. That way I have time to test the X,Y limit momentary by hand. Should any one of the limit...

Re: Lightobject new DSP laser controller card

I don't know.

I think with your electronic knowledge you can test it and figure it out

When the output is "off", there is 5V appears on the output terminal. When it is 'On', it dropped to "0v" in respect to the Gnd

I don't have those detail info from the manufacturer and I have no problem to use the out out to control an IO board or driven a SSR.The output is 5V that's all I know. The current should be 10mA or less and itis better to drive a SSR but not a relay I really don't see the difficulty to use it to dr...

By my rough calculation; 2*pi*r with following parameters: 1.8' degree motor, 8 micro-stepping, motor gear diameter 10mm, I think e...

Not even a simple drawing like a square box under LaserCad? Can't you download the drawing direct to the controller? We ran the LaserCad in so many different perform as I didn't see anything like yours. Check the cable connection in both CN1 and CN2. It one of the cable gotmlise, you could moves the...
