Enter your measured line width (see above) as the bit diameter under bit settings.
Set the feed rate to around 80 ipm. there is practically no resistance from the pen or marker, so technically, you could go as fast as the rapid feed rate of the x carve (314 ipm). But the faster you go, the more dried out the marker can act. So start around 80 ipm and adjust.
Plunge rate: IF YOUR X-CARVE IS STOCK, IT MAXES OUT AT 19 IPM. if you have an aftermarket Z axis and have adjusted your setting, a faster plunge rate will help avoid bleed dots where the pen sits down on the paper.
Set your Depth per pass deeper than your pen engagement to keep it at 1 pass. Typical pen engagement is 0.03" so set it to 0.06"
FINDING YOUR BIT DIAMETER
I'll be adding more to this as I create content.
Last, go to Machine->Advanced to adjust the step over to 80%. If you don't, you'll have a ton of overlap and darker spots. you may want this more or less. you will want to play with the settings to find what looks best to you. This only affects the spots you tell it to fill.
Next set the size of the paper or area which you want to draw.
The most important tip here is setting the Thickness of material to 0.06" so when you set the depth of the carve (pen engagement) to 0.03", it shows up as a darker gray and you can see it.

X-CARVE PEN TOOL TIPS
All you need to do is draw a line on a piece of paper with the writing device you plan to use. then measure the width as best you can with a calipers. use this dimension as the bit diameter.
