ENHANCED- Internal Offset of Axis Datums Prevents Unexpected Negative Motion
I2T servo modules choose an absolute move DIRECTION based on whether the axis starts 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
[display] HOME PROCESS - Home Bend Axis HomeBendAxis= vel0:20.0, cto:60000 [display] HOME PROCESS - Assign new Bend Zero ResetBendArmPosition = pos0:10

CHANGE- Remove Obsolete Properties from the Main.axislist
These properties are removed from the main.axislist because they are obsolete:
If any of this properties are left in the main.axislist file, they will be ignored from this version forward. |
CHANGE- CNC Processor Does Not Check for Collision Errors During Home Process
The CNC Processor no longer checks for collision errors during the home process. This allows CNC Bender the necessary flexibility for different situations in which the bender may find itself during the home process. |
