Page 189 - KNK Groove with MTC User Manual

 The calibration is nothing more than determining how far away, from the tip of the blade, the alignment pin is
located. It can vary slightly from one Groove to the next. Note that you will want to use the same blade
holder with all of your PNC applications, as the distance can also change with larger or smaller diameter
holders.

 The distance is measured in mm in an X direction and in a Y direction:

Tip of blade

X Offset
Location of pin

Y Offset

 This calibration only needs to be done one time, for a given blade holder, and then you can record this
calibration in case you ever need to install MTC on a new computer or you have to reformat the hard drive
on your current computer. The units are in mm which are easier to measure in very small distances.

 The KNK plug-in has a set of default calibration numbers which will be somewhat close to your final
numbers, but not exactly the same. To access these numbers, click on the tiny wrench icon:
Click on the wrench to open the
calibration window Alignment Pin Offset Default Values

 The process involves performing and repeating a PNC to see how much you need to adjust the X and Y
values in order to get perfect results. And you SHOULD be able to get perfect PNC’s! : )

9.03 PNC Procedure Part 1: Setting Up and Printing

 What do you need before you begin a PNC?
 First, you need an image to print, a printer, the alignment pin, and the blade holder you plan to use for
all of your PNC’s. The diameter of the blade holder will impact the calibration.
 You need to be well rested! You don’t want to start learning the PNC process when you are tired,
stressed, or in a hurry. Mastering a PNC comes when you have the time to repeat it about 4 times in a
row. At that point, you will not only have repeated the process enough times to feel very comfortable
with the order of the steps, but you’ll have your calibration perfected and then be ready to do future
PNC’s quickly and with ease.

IMPORTANT: Do not use high speeds when performing very precise PNC’s, including the following

calibration. Set both the Cut Speed (v) to 200 and the Up Speed to 200 (Refer to Section 1.05).

 While it is possible to do PNC’s in either portrait or landscape mode, it is highly recommended that you
select the same orientation you typically use for your other cutting in MTC. If you prefer to work in portrait,
please skip to the Portrait Mode Option section following the Landscape Mode Option section.
