kainth.c.s 53 Posted June 26, 2018 Hi I have a 600 mm Creation PCUT 630 vinyl cutter. I put up a new blade yesterday as the previous one was damaged. I had to put up an aftermarket blade I got from EBAY as the supplier had them out of stock and I had some urgent work to do. I ran the blade on following setting Press: 86 Speed:40 (small text was to be cut) I found that the edges are not coming up square. Please have a look at the attached picture. The word CARBON is a mess. Is it the problem with the knife offset or may be because of new blade it was going deep into the vinyl? Do we need to adjust the knife offset every time we change the blade please? Please share some inputs Regards Share this post Link to post Share on other sites
Dakotagrafx 7,297 Posted June 26, 2018 when you do the test cut from the plotter are the corners square ? if not offset issue. pretty hard to diagnose thru app tape Share this post Link to post Share on other sites
Cal 393 Posted June 27, 2018 Are the new blades the same degree angle as the old one? 1 Share this post Link to post Share on other sites

Do I need to increase the offset or decrease it. I am currently running it on 0.25 Share this post Link to post Share on other sites

darcshadow 1,625 Posted June 27, 2018 You also mentioned the blade was going deep, reset your blade depth following Mz. Skeeter's instructions found all over the place on these forums including a sticking in the instructions section. 2 Share this post Link to post Share on other sites
kainth.c.s 53 Posted June 28, 2018 Just of curiosity, can I run a cemented carbide blade on this cutter(creation Pcut ct630)? the original onea that I got with cutter were Tungsten steel I guess and I have a cemented carbide blade with me. Share this post Link to post Share on other sites
Wildgoose 4,200 Posted June 28, 2018 As long as the blade is the correct size I don't think composition will matter. Share this post Link to post Share on other sites
kainth.c.s 53 Posted June 28, 2018 Thanks. I cut a rectangle with rounded corners yesterday and found the start and the end points are different. I guess this is an offest related issue. Right???? Share this post Link to post Share on other sites
Dakotagrafx 7,297 Posted June 28, 2018 I couldn't tell offset from something that big - so no idea from what you posted. I would think if an offset issue it would be showing on the corners of that triangle more than anything else. did you zoom in close on that part of your vector image to check for errors> 1 Share this post Link to post Share on other sites
darcshadow 1,625 Posted July 2, 2018 Offset affects corner sharpness, start and stop points not matching up is a tracking issue or a file issue. 3 1 Share this post Link to post Share on other sites

The catch is, when I did it for the second time, it came up perfect!!!!! 1 Share this post Link to post Share on other sites

I ran a P-Cut for several years. You are just experiencing tracking problems that are sort of the way it goes with that level of machine. The erroneous spot looks to be the start and stop point of that outer line. Share this post Link to post Share on other sites
