Jimbobz 0 Posted April 13, 2019 Hi I have set my cutter up and and having problems It seems to be wondering off and not closing cuts I have checked the belt tension blade off set which has closed the lines slightly but still has the lines kicking off it’s changed blade holder twice still no distance after 3 days of reading forums and trying to sort this out i have hit a dead end I have attached picture design is with coral draw 2018 cutting software signcut pro 2 many help would be great these are suppose to be circles Share this post Link to post Share on other sites
Dakotagrafx 7,297 Posted April 13, 2019 what plotter are you using? how did you set your blade exposure? - too much exposure puts the point of the blade farther from the center point on a drag knife plotter and why it is important to use the least amount of blade possible on small detail Looks live very very small cuts so adjustments have to be spot on and a servo motor cutter would be best for that small Share this post Link to post Share on other sites
Jimbobz 0 Posted April 13, 2019 I am using a cutter call pixmax only had it a week before that I have a Seiki and had that 2 years with no problem this only started since I got new cutter when the old one gave up it is small cut around 10mm in total and the circles are around 2mm i did blade offset through signcut and fitted the blade as normal with new Roland blade and adjusted with force to get the cut right Share this post Link to post Share on other sites
Dakotagrafx 7,297 Posted April 13, 2019 blade exposure is the big factor not mentioned in your reply here is skeeters instructions:To start with, you should set your blade depth correctly, by taking the blade holder out of the machine, and firmly cut across a piece of scrap vinyl, you will be cutting. You should only be cutting the vinyl and barely a mark on wax paper backing, Adjust blade to get there, Then put the blade holder back in machine, and use the force of the machine to get there, same results, only cutting the vinyl and barely a mark in wax paper backing. You should just barely see and feel the blade tip out of the blade holder. Share this post Link to post Share on other sites
Jimbobz 0 Posted April 13, 2019 This is wot I have done it is more the fact that it is going off course where it is kicking out here is a new picture since I changed ofset i have got the ofset at 0.47 which seems height but this is best result I can get Share this post Link to post Share on other sites
Dakotagrafx 7,297 Posted April 13, 2019 a drag knife plotter drops the blade and pulls it into position like a caster wheel - looks like where the blade drops and not going past - understanding what offset is and setting correctly not based on a particular project is the way to set it - the offset affects how the corners are handled - I don't remember any plotter I have used being outside of the .22-.3 range - so wondering if you are trying to correct a problem with the wrong setting. use the least blade exposure possible . . . .and then set your offset using the test pattern that almost all plotter have in their menu Share this post Link to post Share on other sites
haumana 1,220 Posted April 13, 2019 .47 is kind of a big offset. set your blade depth correctly. slow the machine way down for those tiny 2mm circles. 1 Share this post Link to post Share on other sites
Wildgoose 4,200 Posted April 16, 2019 Test your blade offset on a perfect square. We can't tell from the pics whether the text is supposed to be somewhat rounded or not. I think most of the rolland style blades are going to me more in the 0.35mm range. Your pics show some definitive off-tracking. Those multiple copies weeding boxes don't line up very well and they should be. That can be a result of a lot of things. One being too much blade exposure, poor traction on the pinch rollers (but I we recommend not adjusting them without severe care), too much pressure and too much speed or a combination of all or parts of the above. 1 Share this post Link to post Share on other sites
