JH,
    Wow man you are simply getting WAY too good at this stuff.  You need to start a build a CNC machining center class or something....haha I would be in the front row dude!!  Nice looking machine you have there. I have seen a couple of them come and go for good prices but knew nothing about them.  Good luck on this build, I doubt you will need it. Peace

Pete

Thanks Pete !  It's a beast, got the Y axis moving today ...  It's been 2 steps forward and 1 step back on this project.

ATC Carousel Update
« Reply #52 on: October 17, 2011, 12:39:22 PM »
The ATC Carousel circuit was constructed and installed into the machine.  Wrote some test macros to verify that Mach3 can rotate the carousel in both directions using the DIR and ON/OFF control lines.

The INDEX switch has been added and a new flag was tack welded to the rotating motor plate.  I made the flag long enough to indicate that the entire range is a valid INDEX position while allowing the motor to decelerate and stop from both directions.  The HOME switch has been mounted but the HOME flag needs to be constructed and attached.  Once the sensors are installed, the BP412 Carousel Code will be modified to support 24 positions and tested.

Thanks
JH

JH are you using Modbus and a VB script to enact tool changes? Or?
Thanks!

Yes, VB script for the logic and error handling.  I plan to use both PP I/O and some ModBus I/O for this DM4800 project.  Any I/O will work as long as you can write a macro to access the hardware.

I have attached my M6Start Macro that I used on a BridgePort 412.  I plan to use this and modify it for the DM4800.  

If it works for you, then I'll take credit, if it doesn't work, I didn't write it :)

Thanks,
JH

Many Thanks! I have so much to learn. It is overwhelming. Having a hard time even picking a place to start on my machine.

Hi Wayne can you check if it's stuck in manual mode. Might be a bad start switch or auto/manual switch. Or a feed hold switch stuck on?

Faulty contacts on switches are a good place to start...if it's been sat idle for some months the contacts can corrode with the damp..or the switch contacts simply wear out on older machines. You can usually check them in the diagnostics screen.
