CNC Bender v11-20091201

Type of Upgrade: FLEXIBILITY The changes in this version are changes to CNC Bender for better flexibility.

NEW- Logic Allows Push Buttons to Toggle States

CNC Bender now allows logic to make a physical momentary push-button into a toggle switch. For example, push the button to switch a state on, then push it again to switch the state off. For example, it is possible to use logic in the Constant Run processlist to switch a End Cycle ON and OFF using a push button. It is also possible to illuminate the button according to the current End Cycle state.

ENHANCED- Edge Triggerized [IF] Parameters Optimization

Edge triggers now reset properly when repeating the same inputs in multiple [IF] and [IFNOT] commands in the list of commands. If an edge triggerized input is true in an IF line, then the edge trigger is CLEARED - UNLESS the entire set of logic in that parameter line returns FALSE as a whole. In that case the edge trigger is set back to TRUE (it is SET). This allows for same edge triggered input to be used in several different [IF] and [IFNOT] blocks in the same processlist.

ENHANCED- Internal Offset of Axes to Prevent Accidental Negative Motion

I2T servo modules choose an absolute move DIRECTION based on whether the axis is in the negative region or positive region. When the axis is in the negative region, the axis chooses to move in reverse to the absolute position. This behavior creates a problem where an axis that should only move one direction away from zero, may move in the wrong direction if it is starting in the negative region. To overcome this possibility, we no longer allow these axes to get anywhere near true zero in position internally.

The main.axislist file now has the new property "Zero Position Is Offset To". Set this value to the new internal offset for zero. Zero Position Is Offset To=1000 Follow These Guidelines To Set The Zero Position Offset: For any axis that has a rollover value of 10000 or greater, we will use 1000 mm as the new internal datum. For any axis that has a rollover value of 360 (like the bend arm), we will default to 10 degrees as the new internal datum. Immediately after the home process is completed for each axis, it is also necessary to reset the axes after home to the same value used in the main.axislist file. In the HOME processlist, each axis that uses a Zero Position offset that is not greater than ZERO, should also use a Reset Position comdef like this: [display] HOME PROCESS - Home Bend Axis HomeBendAxis= vel0:20.0, cto:60000 [display] HOME PROCESS - Assign new Bend Zero ResetBendArmPosition = pos0:10 Axes that can go in either direction without colliding with the machine - like the ROTATE axis, can safely use a ZERO offset. (Don't bother to offset the internal zero position.)
