Hi All;
It's been a while since I updated my buildlog, so I thought today was a good day to do it. Since the last post, I received my LO-X7 DSP controller. After a few false starts I finally figured it out and got it up to the point it will run the test program. I was originally trying to use the Laser/interface board that I had used for the Mach3 testing. My intent was to just use it for the stepper drivers and use all of the control circuitry from the new DSP. After changing the Schmidt trigger from a 74HC7014 to a 74HC14 I got the motors running but I could never sort out the limit switches. After messing around with it for a couple of weeks I ordered three 2m415 Stepper Drivers from Marco. After hooking these up to the new DSP everything worked as expected. I still don't know why I couldn't get the other board to work. It seemed so simple at the time
I pretty much finished up all of the wiring this afternoon and I think I am ready to order the Laser tube and Laser Power Supply.
I was pretty much able to fine tune my Manufacturing and User parameters in LaserCad. I think I am ready to see if I can get CorelDraw loaded and working with LaserCad. The version of CorelDraw I have is version 11, which is pretty old. (Circa 2002/2003.)
If anyone has any comments pro or con about using something this old I would appreciate hearing from you.
I have attached a few pictures showing the wiring compartment as it is at the moment. As I said I don't have the HV power supply yet. As always any comments are welcome.
Regards,
Dick
