Hi all,
I'm having problems connecting my DSP board version 2, to the Laser power supply too. If laser PS is disconnected from DSP I can fire the laser with the red Test Pushbutton on PS but if PS is plugged into DSP as outlined in installation direction, the laser fires continuously at 10 MA whenever the machine is powered up, and there's no control over the laser at all.
I'm using an interconnection diagram with the page entitled ' 4. Power supply connection ' I had to send my DSP to Marco at Lightobject, in order to get it configured, and he assured me that it was functioning properly with his laser PS.
He mentioned there are 2 versions of laser PS; analog control and PWM control. Marco suggested I move the J5 jumper from 1-2 position to 2-3 position for PWM control. J5 is located next to LP-1 terminal block.
I moved the jumper but there's no change in condition. I wrote to King at Thunderlaser, his laser PS looks identical to mine, and he sent me a diagram with a connection between either TTL low or TTH high, DSP to PS, identical to the drawing in thiis post.
Has anyone tried this single connection, and did it work OK?
What position should the J5 jumper be in if I'm using the same sort of PS as King at Thunderlaser?
Does anyone have any documentation available for this DSP board?
The Thunderlaser diagram shows 2 ( safety ) switches wired in, one for water, and the other for cover interlock. Do the switches open on a fault or close?
In other words, if the lid is opened, does the lid switch go open contact?
My K40 machine has neither water or lid interlock switches, so I suppose it wire right through.
If anyone needs pictures of what I've got, I can upload whatever you require,
regards,
Denis
