Hey Guys.
Been a while I posted something interesting.
Been busy more than a bit.
I like to share a new experience I had with a CNC Engraver.
This one was brand new. Owner bought from China and shipped via DHL and cost a lot. Well more than I can buy one.
Problem was he can never get this to run. No matter what. All it does is spindle motor run. Obviously it was controlled manually. So motor Runs. Other than it was useless. He came to me when he ran out of options.
So I checked. The software does not run, meaning no change in axis control. Owner tried with Win7 and XP and all tht.
I found two problems after banging my head for two days. A DC to DC controller on the PCB was dead plus the Y axis IC. Good thing I bought those to build my CNC.
The DC to DC controller was one thing I cannot get here, so I compromised. I added an extra winding to the Tx ( good thing it was a toroid ). Made a 7805 regulator and replaced the IC.
Re installed win7 and Mach 3 and studied the LPT pin out on PCB. Had to change the Reset pin. And bingo it started to work.
Managed to to do a sample from the installation CD
But I had to admit building a CNC is one thing. And to Engrave is another whole ball game.
Still learning how to Engrave and do proper tool path. This is tough.
Managed to destroy a sample tool bit... forgot to start the spindle.
And still learning the Drawing Software.....Man this is not the same as repairing a CNC !!!!
PS. I always thought drawing and sending to CNC was the easiest part As like draw in corel and sent to printer. I was dumber than I thought. Eh!
