Hi all! This may have been covered in the past, but after spending an hour searching about and finding nothing here, I thought the subject was worth a fresh new thread. . . After a few months and hundreds of hours of dutiful drawing on my handy-dandy Portege M200, (awesome art tool!), my hand-eye-stylus awareness (for lack of a better term), is now pretty sharp, and I've been finding that the standard Wacom driver doesn't offer the kind of fine-tuning I want with regard to pressure sensitivity. And so, after digging around I found the following website which offered some instructions on how to get into the guts of the Wacom settings and tweak it to my own personal satisfaction. (As opposed to that of the Wacom engineering staff.) You can look at the original website. . . http://junkyardsam.blogspot.com/2009/02/wacom-cintiq-driver-manual-adjustment.html I'll repeat and adjust the relevant steps here. . . (The fellow who posted was doing so for a Cintiq. It's a little different for a Tablet PC) --The following steps assume that you have the latest Wacom driver for Tablet PCs installed on your system enabling pen pressure support. 1. Open up the Wacom Properties window from the control panel or start menu, set the pressure sensitivity slider to the middle and close the panel again. This isn't vital, but it puts you on the same page as these instructions. The Wacom Properties window needs to be closed for the next steps to work. 2. Go to Settings > Control Panel > Adminstrative Tools > Services. Highlight TabletServicePen, right-click and STOP the service. --This turns off your pen, so you'll need a mouse plugged in to continue navigation. The reason you turn this off is so that you can edit the Wacom driver settings while they are not engaged. You'll turn them back on after you're done tinkering, so keep the Services window open. 3. Navigate to the Pen_Tablet.dat file. . . C:\Documents and Settings\Administrator\Application Data\WTablet\Pen_Tablet.dat It may be in a different place depending on how you have your version of Windows set up, but you'll find it eventually because if you have the Wacom driver installed, then it's there someplace. Also, you'll need to set Windows so that hidden files are visible. It might be a good idea to back up this file in case things go horribly wrong, though Wacom's driver will generate it again automatically, so it's no biggie. It IS handy to have a copy with the settings all at the base line for handy reference while you're doing this next part. . . 4. Open up the Pen_Tablet.dat file in a text editor. Scroll down to the following line. . . (It's within the first 50 lines of the document). "PressureCurveControlPoint 20 0 127 127 254 254" (If you followed step 1, then the numbers you find will match those above.) --If your stylus has an eraser, then you'll see this same line appear twice, (perhaps with different numbers). You need the second one. The first refers to the Eraser button. The way you know this is that the line five up reads, ButtonName tip (As opposed to ButtonName eraser) 5. The numbers. . . There are three pairs representing the bottom, middle and top of the pressure curve. Here's what they mean. . . 20 0 = You have to apply 21 units of pressure to the nib to get an output of 1. Anything less and the Tablet registers a zero output. It's best to leave a bit of a buffer like this so as to avoid un-intended clicks. Wacom's default settings on this end of the curve seem to work well. 127 127 = This is the middle of the pressure curve. You apply 127 units of pressure to get an output of 127. 256 256 = This is the top of the pressure curve. You apply 256 units of pressure to get an output of 256. Pretty simple. Now you know enough to experiment. --My current preferred pressure settings are the following. . . "PressureCurveControlPoint 38 0 200 70 254 254" This simulates a nice firm nib but with a little more flex to it than the Wacom Properties menu allows for, as well as a faster drop off when I lift my hand, (preventing too-long 'ink' trails). --I also changed the two lines ahead of this setting to the following figures... "UpperPressureThreshold 38" "LowerPressureThreshold 36" I'm not entirely clear as to what these do, but it's what the Wacom driver automatically sets them at when its native pressure adjustment bar in the Wacom Preferences window is set to one space from the maximum, (where I normally worked at before I started tinkering), so I felt I shouldn't argue too much with it. Perhaps somebody has a little more insight into what these numbers do. In any case, none of these settings appear to be mission-critical; meaning, you can tinker with them with no fear of crashing your computer. Your pen will simply act funny. Restarting the Wacom driver and pulling the pressure slider left or right will reset everything to the default values. It's all reasonably fool-proof. 6. Save the Pen_Tablet.dat file with your changes and re-start TabletServicePen in the Services window. Then re-start Photoshop (if you're using that program for your drawing), to have the changes take effect. Then test out the responsiveness of your stylus. If you want to make further changes, just turn off TabletServicePen again, and head back to your text editor. That's it! I hope this has been useful to those of you who haven't already figured this stuff out. It has allowed a more snug fit with my personal style of drawing. Cheers!
