Graphtech Condition 2 skewing

Recommended Posts

Good day to all,

Machine: Graphtech plotter  FC8600-130  64"

Trying to find a solution when i send my projects normally 50"w by 60"h  registration marks made with Ai Plugin, I assign condition 1 and condition 2 in CuttingMaster3 normally and it cuts well except when condition 2 starts...sometimes the first line cuts good but going up it begins to skew upwards each line it changes more eventually damaging the first cut.

All wheels are in their respective position with medium pressure.

One solution ive found without problem is sending condition 1 separate from condition 2  so each one sseparately works perfect... but for speed i want to send both at the same time. What could be the problem...a fix besides sending separate cuts  Any input would be appreciated.

Thanks

I was looking at the pinch roller adjustment in my user manual and it is best to have the 2 outside pinch rollers with more pressure than the inside pinch rollers. There is a page in the user manual for how your pinch rollers should be.  And I don't know if you knew it,  but you can get FREE  Graphtec ProStudio software from Graphtec for that vinyl cutter.  It is over $1000 software, like Flexisignpro..    I only use Flexi software with my Graphtecs.   Also, you don't state how you set your blade depth.  Hopefully blade depth is not dragging on your vinyl.

cutmaster is a plug in - graphtec pro studio is just like full fledged flexisign pro except it doesn't have the RIP feature for our wide format solvent printers - so like comparing grub hub to a 5 star restaurant

skeeter - you ever cut with pressure that high? I usually run 11-15 depending on material - think at 20 I could cut leather.   messing with pressure roller tension has never made things better in the thousands of post I have read - - - - it only causes more problems - will wait to hear from others

Never!!  does your blade even have a tip on it anymore. or anything left of the blade? :blink:  I am usually at around 10-11 with a new blade, Most ever 13 with about a blade  9-10 months old.  Is that a foreign measurement?

I used 15 once with some thick reflective on a over used blade - - -

Did you ever try the GraphtecProStudio software that we gave you the form for?  Much better than what your using.  Are you sure that you don't have gouges in your cutting strip now? You should be able to see if the blade is damaged, compare it to a new blade.

On the newer Graphtecs, It's just a matter of how far you push the lever down. They have steps on them.  Graphtec even has a chart for it in the user manual for 2, 3 and 4 pinch rollers. That is why I told him that.

Hello B)

 

This is an example of what happens

Top line is sending it with condition one and bottom line is the correct one that doesnt skew when i send it alone. btw it improved changing the force to 15 but the last line got messed up (see the pic)

 

 

 

 

Not sure if you can see thats the lenght i been using for condition 2....Blade looks fine

What has Graphtec tech support told you as far as help?    Your welcome.   Are you in the USA?   If not, the US Graphtec cutters are different.  They are Graphtec America.

Well no matter what your cutting you have to set the blade depth correctly. and it's not just by looking at the blade.  This is how you set it correctly. 

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.

Hello

wanted to give an update about the "problem" i was having.:D

Looking on the condition settings i found the distance adjust  x: being 0.45% and y:0%

I changed x to 0% and it has fixed the skew problem 

gotta be careful when editing those settings 

thanks all for sharing
