kainth.c.s 53 Posted January 6, 2016 Hello fellas I recently did some strips for a car for covering some old paint damage using Creation PCUT CT0630 I noticed that while cutting the strips the cutter knife didn't finish at the same place thus giving a tail on one side( see attached). Any ideas wherein I am going wrong please??? These strips are 11 mm wide and 1800 mm long. Also I noticed that the sheet starts to deviate when cutting the length of the strip, I mean the width is not uniform as if the sheet is slipping out of the rollers My operated settings are as follows: Speed 50 Press: 118 Offset:0.02 Regards C.S.Kainth Share this post Link to post Share on other sites
Wildgoose 4,200 Posted January 6, 2016 Do you have any overcut set? I used to run about the same overcut as the offset number if I remember my setting from the P-Cut days. Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted January 6, 2016 Do you just have the zero in the wrong place? metric should be 0.25mm offset as a starting point. . This is Metric 0.25mm This is inches 0.00984252 same equivalent... Being in the US I use Flexi in inches Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted January 6, 2016 This is your first post way back when you signed up to the forum.. stating you are using Flexi, You have your offset at Inches Knife offset : 0.009 in So why are you now at 0.02? 0.51mm =0.02007874 in What do your test cuts look like? USB cable as connection port WIN XP SP03 Press: 118 units Speed: 40 units (due to small decal size) Blade 45 deg standard vinyl Blade (1.5 mm shank dia 23 mm length) Knife offset : 0.009 in Flexi 10 Basic version. The cut is otherwise fine.The blade sticks out of the holder by 0.5 mm. Please help as this issue is driving me insane.

KYSIGN 233 Posted January 6, 2016 Tracking can be an issue at that length. Prefeeding the material can help sometimes. Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted January 6, 2016 So your doing 11 mm = 0.43inches 1800mm = 70.87 inches Hard to do on a value cutter. Like KYSIGN said. Share this post Link to post Share on other sites
busterbay 326 Posted January 6, 2016 I usually run my cutters at .45 . Turn the feed speed down and pre-unroll. I know I wouldn't cut that on my SC as it becomes inaccurate after 36". My Titan I would. Share this post Link to post Share on other sites
kainth.c.s 53 Posted January 8, 2016 Mz SKEETERSorry my mistake yes it is 0.2 KYSIGNI couldn't get the term PREFEEDING. I usually leave about 100 mm on the front end to start. Is this something you mean by prefeeding WildgooseNo my friend I do not have any overcut set on the parameters Regards SINGH Share this post Link to post Share on other sites
kainth.c.s 53 Posted January 8, 2016 Mz SKEETER Buddy this overcut thing occurs only at the finishing corner, so I am thinking it is not the offset issue What your opinion buddy? Regards SINGH Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted January 8, 2016 Prefeeding is to run the vinyl manually thru the vinyl cutter and back with the arrows on your machine the entire amount of your order, And make sure the tracking is nice and straight.. You should have slack of over 1800mm vinyl pulled from your roll for this order. Higher end cutters, can prefeed the vinyl automatically. a certain amount.

Wildgoose 4,200 Posted January 8, 2016 I just re-read your original and see how long you are trying to cut and agree with the others it's most likely a tracking issue. I would say with a value cutter you are probably lucky to get as close as you did! Ha ha! One option you might try on simple things like that strip is use the feature that I think flexi has that lets you cut in increments as you go. So I don't use flexi and can't tell you where to find the setting but it will cut everything within a user defined distance, lets say 12 inches, before moving along to the next 12 inches and so on until it gets to the end as is complete. It will allow longer runs on a cheaper cutter. If you don't have this you might try SignCut Pro (they have a 7 day free demo). This feature doesn't work as well with complicated designs like or lots of small text because the budget cutters aren't accurate enough to come back and connect all those connection points but for long simple stuff it can save your bacon.

GraphxNMore 282 Posted January 8, 2016 Is it when finishing EVERY cut, or just that one? Could be the file. Share this post Link to post Share on other sites
kainth.c.s 53 Posted January 8, 2016 Mz SKEETER Thanks for the info my friend. Wildgoose Sure my friend I will have a lookout on this feature. Is it available on basic version or pro? Morever I am doubtful that cutting long lengths in increments may render start and stop marks on the vinyl strip. Can you or anyone who has used this feature put some light on this? Eazy No my friend it is not the file issue as I made the file in dxf and checked by importing in flexisign and exporting it back to dxf It did at the finishing of every long strip.

kainth.c.s 53 Posted January 8, 2016 Mz SKEETER Wildgoose Eazy Please have a look at the job I was talking about. The red strips at the bottom drove me crazy Is it ok to have a liitle shift in the other axis when cutting long lengths as well? I carefully checked and found the width was exactly 10 mm at the start and it changed to 12 mm at the other end. It was as if the vinyl was slipping from the rollers. I used AVERY 900 SUPERCAST Hi gloss vinyl for this job Regards Singh +61426141448 +61410060124 Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted January 8, 2016 That is tracking problems,,,we asked you if you were prefeeding your vinyl.. You never answered.. It will be very hard for a value cutter to cut straight at those lengths. The vinyl has to be perfectly straight and never shift from top to bottom.. That is why we buy Graphtec and Roland vinyl cutters. They are much more accurate with tracking. Try Optimize cutting order in Flexi. Also make sure your pinch rollers are placed the same amount in from each side of the vinyl. Share this post Link to post Share on other sites
Wildgoose 4,200 Posted January 9, 2016 Skeeter- I thought flexi had step-by-step cutting? No? Kainth- if you can't find a step-by-step function in your current software I strongly urge you to try out SignCut Pro for the free week the next time you have a pinstripe job. I had a 36"x 96" sign that had a large partial oval 3/4" wide stripe with a flat bottom that covered the entire expanse. So there was two 8ft long cuts that had to match up for the stripe to look accurate and the only way my old P-Cut got it done was with the step-by-step. You are definitely experiencing tracking issues and there is nothing much you can do about that on the machine. They just aren't built for it. The step-by-step feature in SIgnCut just tackles a little at a time which is defined by you so I would do a foot at a time and see the results. Those stripes look really good in the pic. Maybe up close there are some inconsistencies. Share this post Link to post Share on other sites
MZ SKEETER 4,708 Posted January 9, 2016 My Flexistarter has Optimize Cutting order and you choose the distance, then advance on. But I use Tile. It does not cut through the tiles,, It just cuts everything in the first tile, then next tile and so forth and advances on to the end. First tile photo I only used a few tiles. 2nd photo, I used more tiles,,That can be changed to suit the design..The black lines are not cut thru. And you want a little overcut.

kainth.c.s 53 Posted January 9, 2016 Mz SKEETER Buddy I did check by prefeeding the vinyl before cutting. At prefeeding, it goes fine but it overshoots when cutting in actual. I am much more convinced that it is the tracking problem at such length. I will keep all the checks you said and if it doesn't work may be I have to shift to some good machine.

kainth.c.s 53 Posted January 9, 2016 Wildgoose Sure I will give the step by step cutting thing a try otherwise if things don't work out, I will have to shift to Sign cut pro. Thanks a lot for the inputs Regards Kainth Share this post Link to post Share on other sites
