Get/SetParam() Vars
From MachCustomizeWiki
Here is a word list for the GetParam( String ) and SetParam( String ) in VB
"ZMachine" = Z Mach Positions (G53 Coordinates)
"XMachine" = X Mach Positions (G53 Coordinates)
"YMachine" = Y Mach Positions (G53 Coordinates)
"Encoder1" = X Encoder Position
"Encoder2" = Y Encoder Position
"Encoder3" = Z Encoder Position
"Encoder4" = A Encoder Position
"MPG1" = MPG1’s count
"MPG2" = MPG2’s count
"MPG3" = MPG3’s count
"XScale" = X Axis Scale
"YScale" = Y Axis Scale
"ZScale" = Z Axis Scale
"AScale" = A Axis Scale
"BScale" = B Axis Scale
"CScale" = C Axis Scale
"FeedRate" = Feedrate that is active
"Units" = 0 or 1 for mm or inch
"StepsPerAxisX" = X Steps per unit from the motor tuning page
"StepsPerAxisY" = Y Steps per unit from the motor tuning page
"StepsPerAxisZ" = Z Steps per unit from the motor tuning page
"StepsPerAxisA" = A Steps per unit from the motor tuning page
"StepsPerAxisB" = B Steps per unit from the motor tuning page
"StepsPerAxisC" = C Steps per unit from the motor tuning page
"VelocitiesX" = X MaxVel from motor tuning page (SetParam as units/second. Mach will multiply X60 for display in motor tuning as units/minute.)
"VelocitiesY"= Y MaxVel from motor tuning page (SetParam as units/second. Mach will multiply X60 for display in motor tuning as units/minute.)
"VelocitiesZ" = Z MaxVel from motor tuning page (SetParam as units/second. Mach will multiply X60 for display in motor tuning as units/minute.)
"VelocitiesA" = A MaxVel from motor tuning page
"VelocitiesB" = B MaxVel from motor tuning page
"VelocitiesC" = C MaxVel from motor tuning page
"AccelerationX" = X Max Accel from motor tuning page
"AccelerationY" = Y Max Accel from motor tuning page
"AccelerationZ" = Z Max Accel from motor tuning page
"AccelerationA" = A Max Accel from motor tuning page
"AccelerationB" = B Max Accel from motor tuning page
"AccelerationC" = C Max Accel from motor tuning page
"SpindleSpeed" = Active Spindle speed
"ZInhibitOn" = 1/0 for Z inhibit on/ off
"ZInhibitDepth" = Max depth of Zinhibit
"SafeZ" = Safe Z height
"XDRO" = X Position
"YDRO" = Y Position;
"ZDRO" = Z Position;
"ADRO" = A Position;
"BDRO" = B Position;
"CDRO" = C Position;
"XRefPer" = X % speed for homing
"YRefPer" = Y % speed for homing
"ZRefPer" = Z % speed for homing
"ARefPer" = A % speed for homing
"BRefPer" = B % speed for homing
"CRefPer" = C % speed for homing
"RPMOverRide" = SetParam("RPMOverRide", 1) will allow you to write to OEMDRO39(True Spindle Speed) from the modbus. If set to "0" will read True spindle as usual.
