#### LK Direct tab

Machine Options dialog box - LK Direct tab

The LK Direct tab provides specific settings for your LKRS232 interface.

LK 2000 - If the controller is an LK2000 type then this option needs to be selected.

LK 3000 - If the controller is an LK3000 type then this option needs to be selected. You must also select the LK2000 if you select the LK3000 option.

Micron Drive - If this controller is a Micron Drive, then this option need to be selected. Note: The Micron Drive controller never uses GPIB communications.

GPIB - Select this option if your controller uses the GPIB protocol to communicate.

PH9 - Select this option if you are using a PH9.

SETPT - If you find that the machine will not register hits then you may want to select this option.

Homing Velocity - This value sets the homing speed. If the machine drives to the limits before reaching the home position then you should decrease this value, turn the controller off, and try again. It should reach the limits and then find the home position for each axis if this value is correctly set. Default is 1.

Move Speed - This value sets the overall move speed. If you find the move speed is too fast even when you set it to a slow speed inside of PC-DMIS then you should decrease this value. Default is 1.00000

Wait for prehit - This value should be left at 0.

Move buffer - The number of moves that can be sent to the controller buffer at one time. Some machines will give errors if we send too many moves in advance so reducing this will help. Decreasing this value will however reduce the system performance, if for example we set it to 1 then we will only send the next move command when the machine has finished the previous one, this will cause the machine to pause between moves as each command is sent.

No start button - If there is no Master Start button on the controller (or jog box) then you should select this option.

Auto speed optimization - Certain LK controllers support Auto Speed Optimization, a controller feature that will drive each axis at its maximum independent speed for each move. If you know that your controller supports this then you can select this option.

Caution: These values should only be changed by a trained technician. Altering these values may give an undesired result.
