General Mach Discussion / Quick Mach 3 digitizing probe question
« on: November 30, 2012, 06:58:25 PM »
Hi,
Could someone with Mach 3 digitizing probe experience give a newbie a hand?

I have a CNC Shark Pro that I have recently converted over to Mach 3. The old software I was using utilizes a "touch, and drag horizontally across the surface" method that seems to want to hang my probe up ion the work surface in areas. I've had this happen quite a few times and have luckily caught it before expensive damage ensued. I have 2 different probes and the same has happened with both of them. Needless to say, having to babysit a 10 hour probing session is tough enough but when it hangs up on the surface 6-7 hours into the operation and you lose your whole scan from doing an emergency stop....well, it tries your abilities to suppress the tool throwing reflex!  :D

Does Mach 3 probe in the method I described above or can it do the pin probing where it lowers, touches the object, raises back up, moves over and repeats? I've seen videos of machines doing this and I think it would be a better method for my application. I'm just trying to get as informed a possible and I think this would allow me to start the cycle and go do other things in the shop. I'm out of toothpicks necessary to keep my eyelids propped open and I really need to cut back on coffee.  ;D

Thank you for your help!!!

General Mach Discussion / Need break out board suggestions
« on: March 16, 2012, 01:38:30 PM »
Hi, I have a CNC Shark Pro with a Xylotex 3525 3 axis board and an ncPod. The current set-up isn't Mach 3 friendly even with the firmware and driver changes and I'm wanting to get away from the ncPod altogether and put a break out board in it's place, which should add quite a bit of attachment capability and allow me to run my digitizing probe, add an E-Stop, a jog controller, etc. The Xylotex has a DB25 connector for input so I would need a break out with DB25 for interfacing with my computer and output to the Xylotex (DB25 on both ends, essentially).

Could someone make a low cost suggestion? I recently lost my job and trying to make a few bucks on the side (and possibly go fulltime) with the machine. I've seen the CNC4PC boards in the $100 range and they look very nice but I was hoping to find something much cheaper to get me back on my feet. I see all of the $30 boards on ebay but nothing has a DB25 output that will plug directly into the Xylotex. I am a novice so if there is a method of connectivity that I'm not aware of that would be essentially plug and play I would appreciate the guidance.

I would GREATLY APPRECIATE if a someone could help a brother out.

Thank you and God Bless!!!!
Chris
