Did you get te configure all the functions?  Spinlde Control, Safety Charge Pump, Coolant Pump?

Thanks,

Yes,

The board is fully assembled. It is for 4 axis only.  Yes, you will attach the steppers to this board.  If you need 6 axis, take a look at this board http://www.cnc4pc.com/Store/osc/product_info.php?cPath=33&products_id=45. The picture is from the first version of this board.  We are currently shipping revision 3 of this board.  Take a look at the new picture.

Thanks,

Arturo Duncan

Rceebuilder,

Did you check your output pins? And motor output?  Do this under Conifg / Pins&Ports. You might have that pin used for a motor, spindle, or safety charge pump.  Those are the things I can think will generate a series of steps.

Rceebuilder,

If sometimes you have 2 volts on pin 17, then maybe you a safety chege pum enabled. Check your output pins. 4.45 is a hi, 2 looks like an average from a pulse train, that could come from a safety charge pump, which by default comes configured in mach on pin 17.

John,

That will work, but you would still need to add a turret lock a couple of sensors.  The turret could loose position while cutting and you would never know, causing a serious safety issue.  If you mounted an encoder or use servo and read the encoder position you could monitor the turret position at all times.

From my experience an adding a mechanical lock using a solenoid pneumatic valve and pneumatic piston will do.  The sensor for the turret home and turret lock are a MUST.

Your proposed solution will imply major mechanical reforms for Brian’s small machine that already has a tool changer.

Brian,

I have a new board that has built in most of the electronics hardware you would need for a project like this.  Saving lots of bucks, time, and making it pretty simple to do (Isn’t this mach is about?).   This I the board bengt used http://www.cnc4pc.com/Multifunction_CNC_Board.htm.  He was one of “beta” testers. 

If you would like to consider using it in this project I would gladly send one for testing.  This is new board I can use all the feedback I can get.   I also have a bidirectional breakout board for the second parallel port and inexpensive optical sensors that could also send and you will find very useful reading the index pulse, home positions of the axes and tool turret. 

I have Hardinge HC lathe that I converted and use it mostly for testing.  I run the 8 post tool turret with a macro that you help me with.  I added an index pulse on the turret for homing on start up and a sensor on the turret lock.  So the machine will not start until the turret is securely locked. 

With that setup I run an automatic bar feeder and still have enough inputs to read back the encoder’s position of the axes servos.

Please confirm if you want to consider testing this board.

This new board comes with many of the features of the other boards that I have been offering.  I believe users will find they will save time and reduced wiring as it already comes with many built in features.  It is also great for use in systems that are already in place since it comes with a DB25 connector for output. 

Check out the board at:

http://www.cnc4pc.com/Multifunction_CNC_Board.htm

The features of this board are:
• Fully optoisolated
• Built-in Safety Charge Pump.
• Built-in Variable Speed Control.
•Built-in 10 amp AC Solid State Relay.
• Built-in 8 amp Solid State Relay with NO and NC positions.
• All pins can be used in a concurrent manner.
• Buffered outputs.
• Status LEDs on all inputs and output connections.
• Has an extra DB25 female connection for output.
• Output pins 1, 2, 3, 4, 5, 6, 7, 8, 9, 14, 16, 17.
• Input pins 10, 11, 12, 13, 15.
• Input and output pins with close by ground connections.
• Easy installation of an On/Off switch. You can control the card externally.
• All TTL 5VDC signals.
• Works directly with popular CNC hardware and software.
• Screw-On connections for all terminals.

Benergy,

A macropump is a marcro that runs under mach in a loop manner.  It is running all the time.

I am away from you machine now and do not have access to the macro, but I did it following the guidelines in the wiki for making a pendant using a modio.  All the procedures are the same, it is just that inputs pins are not set to port 0, but to the actual port you are going to use.

Enclosed find the link. http://www.machsupport.com/MachCustomizeWiki/index.php?title=Touch_Screen_and_panel_controls_using_ModIO
