Hi, Happy-Grizzly

Post your DXF, Use the REPLY button and Additional Options button.

On the left side of LCAM, Projects Tab you can move the Chains cut order around and move them to a different layer.

Did you Clean and Optimize on the right side first.

Hi, Travis

You Should Not have 5 volts on the Outer Shell, It's a Gnd/Shield, Pin's 18 through 25 are also Gnd/Returns pin's.

On the Printer Port connector on your Computer the outer shell and pin's 18 through 25 all come together as Ground's.

That's why your BOB board is Shorting Out Everything.

Pin's 1 through 9, 14, 16, 17, are output's used by Mach to send 0 volts or 5 volts to your BOB/motors/turn on and off things.

Pin's 10 through 13 & 15, are input's used by Mach to see, 0 volts or 5 volts from your BOB/system/limits, E-stop switches, speed pulses and such.

Thanks, Chip

General Mach Discussion / Re: My first servo conversion, Tuning advice needed.

Hi, John

Make sure when you use the arrow keys that you set the Program Run screen, Feed-rate to above the value in Motor Tuning, Velocity setting and that your Slow Jog Rate is set to 100%.

Shift + Arrow keys & MDI G00 moves by-pass the feed-rate value and Jog % settings.

Re-Start & Motors Re-Tuning is required after kernel speed changes.

Just Some Thought's, Chip

General Mach Discussion / Re: Stepper motor Encoders

« on: June 07, 2008, 02:27:56 AM »

Hi, Roger

Mach doesn't have a active feedback system, It relies on your servos or steppers to move to the correct position by the settings in motor tuning Steps Per value, There is a board that will halt mach if the steppers get out of position to far that uses encoders , But dose not correct for the error.

You may need to adjust your Acceleration and Velocity down if your losing steps and increase your Step/Dir Pulse to 5 to give your stepper controls more time to see Machs step Pulses.

What are your Steps Per values for each axis ?

Hope this Helps, Chip

Hi, Travis

Check to see if you have 5 volts on any of these pins, 18 - 25, With your cable/BOB not connected to your computer.

Thy should all be Gnd.- 0 - Return pins and should be 0 volts, Check the connector metal housing also.

Hood, What is "Gnd.- Zero" ?, Answer:  eB oT ecalP daB A
