sparkness 1 Posted December 9, 2008 I just purchased a laserpoint 24 and I wanted to cut some gaskets so I wanted to make sure the cutter is on the money. The manuals are vague as to how to use the X_Scale, Y_Scale settings Using a plotter pen, cut (print) a test rectangle to the cutter. I printed 20" x 1" in both X and Y direction on 17 x 22 paper measure the rectangle. Mine measured 19.930" in the X direction and 19.980" in the Y. I used a stanley tape measure and magnifying visor to read read the measurement as close as possible. take the cutter off line press the mode button and get to X_Scale and Y_Scale and record your default values. (my values X=25795, Y=25858) add or subtract and make tests and measure again. Repeat, adding or subtracting accordingly In my case I started adding increments of 10 and reprinting till it was on the money my final values X=25860, Y=25878 so from what I extrapolated my cutter was off by .070" in 20" in the X direction and .020" in 20" the Y direction this equates to .042" per foot in the X direction and .012" in the Y direction. I cut a 5.00" by 5.00" square and measured it with dial calipers it was DOBA give or take a thou (DOBA=Dead On Balls Accurate) Note: scale adjustments can be made in software as well Share this post Link to post Share on other sites

sparkness 1 Posted December 9, 2008 The paper was 22" x 17" and the printed rectangle was 1" x 20" . I orientated the paper accordingly Share this post Link to post Share on other sites

Pistonpump 6 Posted December 12, 2008 SO if I Understand this correctly this has nothing to due with contour cutting? Just to make sure what is on the screen (size) is what is actually cut? George Share this post Link to post Share on other sites

MecH 0 Posted February 1, 2009 how did you get a 20 inch rectangle to fit on a 17 inch piece of paper? bb LMAO...sry, had to share that I just spit Dr. Pepper all over my keyboard when i read that.....I had just gotten through reading what felt like a trig lesson and then cutme had to go and throw logic into it LOL.... Now if you will excuse me, I have a LCD to clean off. Share this post Link to post Share on other sites

sarconastic 29 Posted March 25, 2009 I am so glad I stumbled across this article. I just got LP last week. I have been trying to get my offset to work so everything closed and the corners look right. I was having a problem with the insides of small letters mostly. and on circles they were closing but a little rough. Once I read this article I adjusted my X from the default 25795 to 25805, it was short around 1/32, I had to adjust my Y axis from the default 25878 to 25718, it was long by over a 1/16". Made these adjustments, got my Offset dialed in at .12 my corners are nice and sharp, and my circles are tight. Everything is copacetic as it should be. I learned a long time ago, when I worked as a CNC Maintenance Technician on huge CNC controlled machines, that if the machine is not setup correctly, then you will be limited in quality by those settings. Same goes with these machines. After I set everything up, I went back and cut a couple graphics I had done before that were a little tough to weed. 10X easier when the Cutter is doing it right. Thanks for the info here. Kevin Share this post Link to post Share on other sites
OutlawCustom 0 Posted April 7, 2009 Just want to throw my own THANKS! in here since I was finally able to slow down long enough and register! The LP24 is my first cutter and your post about calibrating it helped to solve a -world- of pesky problems. I can't say how much I ultimately wound up adjusting the LP off of "factory settings" but it was fairly substantial (I worked in units of 10, then 5). I also wound up changing the blade offset from .25 to .15 and gave it a little wipe of silicone lubricant in the process (I saw that mentioned in another post and decided it couldn't hurt since the thing -does- turn a LOT when cutting). I think I finally have the blade depth where it belongs, too, since it's cutting the vinyl (Oracal 651) pretty much perfectly and not really scoring the paper backing anymore. One change I made to your technique was to set my software (Flexi) to Metric then use the plotter pen to draw a 10cm square. Working in metric is super easy for so many things (I -hate- fractions... decimals are so much simpler!) and since most rulers have a Metric side I had everything I needed to do the job. It took about 6 adjustments to get the system dialed in to where it needed to be (X was short and Y was long). I don't have calipers to check the final (cut) product, but I did just do a set of keyhole graphics for a friend's car and the circle was perfect and the end result made him extremely happy. I also have virtually no mis-cuts and very tight, square corners now, even on fairly small text. Thanks again for sharing your experience - you saved me a LOT of grief!

Junkman 0 Posted April 9, 2009 I do a lot of work on motorcycles and small engines and I never thought of making gaskets with the cutter. For the prices the dealers chage for these things I may never buy another one again, I can buy a roll of gasket material for what one gasket costs. Thanks for the great idea and the setup info.

routesmith 0 Posted August 5, 2009 Is there some central database of motorcycle gasket .eps repository somewhere, or I guess its just a buy once, scan, then cut as much as you like? Wayne Share this post Link to post Share on other sites

LOBO 0 Posted August 6, 2009 having trouble testing the LP... im following the noobie tutorial.. made the 100x150 mm rectangle... hit cutter....... what appears is the 150x100mm rec ... but inside another bigger triange.. the other is 187x160... the only other change is the .25 blade offset recommended.... what happened... the inside rec measured 100x150.... need some help Doc1.pdf Doc1.pdf Share this post Link to post Share on other sites
CRD 9 Posted August 6, 2009 If the 100x150 is correct size do not bother the larger triangle. I think in SB you have something switched on that makes the extra square. Paco Share this post Link to post Share on other sites
