Thank you, Sue! I am grateful for the wealth of posts that were posted here. I guess I have not explained myself well enough and people don't understand what I want

You asked the question on why the material would be wasted, so I replied to you with a legitimate answer..

Probably because I don't want to cut the roll into sheets.

It's called nesting in the industry; you can get more parts out of a single 24 ft long sheet than two 12 ft sheets, depending on the part dimensions. If one part is 13 feet, neither sheet can be used and is why longer steel lengths are better (in this case magnet material).

The material is expensive and the market doesn't support high margins, just the way it is. Honestly, the prefeed would function perfectly if there were more than two options. If it didn't have that ramp up acceleration it wouldn't trigger an error. I don't see why I can't set the pre feed speed in cm/s.

Cutting the material would be a waste of material for subsequent jobs where the cut line would've fell onto the next sheet, which potentially means a loss of 280mm of material. The roll should be kept continuous to not waste the material. The geometry of the stock rollers is what causes unnecessary drag, they should be mounted up higher so that the material feeds in a planar manner and not angular (the departure angle of the roll). Most jobs would be 560x560 but I may occasionally get odd ball jobs from customers that need to be 560mm in width by whatever length they specify. Hopefully you understand..

I was thinking that more rollers increases the amount of pulling weight and more traction, since the weight is spread out over four rollers. I already built a smooth melamine outfeed table that mounts to the stand and that turned out nice.

I wanted to utilize that feature. I think the media stocker rollers are mounted too low and the pulling angle creates drag that it has to fight against.

WV. Do you think having more push rollers would stop the 'media too heavy' error from occurring when I do the pre feed? The error occurs even with the pre feed speed set to slow. It prefeeds fine at first and then as it accelerates it triggers the error; if there were a way to disable that acceleration/ramp up for pre feeding, that would solve my issue.

There's not a dealer close to me.

The force is currently at 28 and speed set at 2cm/s with acceleration of 1. I've heard that people have problems with tangential emulation, so I didn't think to try using that since it's not a true tangential machine and I don't think I need it, as all of the DXFs have corner radii and never sharp transition corners. I uninstalled Sure Cuts a Lot since it's not very good software and am using the Illustrator and Cutting Master 4 plugin, which allows me to use the plotter on the network and is awesome! DXFs seem to be importing fine into Illustrator for now. Still curious on how the push roller assemblies are installed so I can keep that as a last resort. None of the service manuals mention it.

Would it be a bad idea to cut the magnet with the 3M wax paper side facing the blade? I would get more traction with the grit rollers biting into the magnet material, but the swiveling blade may 'gum up' as it cuts through the 3M acrylic adhesive? Just wondering. Thanks for your input!

The Graphtec service manual for the FC8000 doesn't even show how to change out the push roller assemblies.

I'm having trouble locating the post where someone installed the extra rollers; I could've swore I found it on other forum before while doing my initial research of plotters.

Does it look hard to install/take off the rollers? The square bar looks like it runs through both sides of the machine and it looks like it needs to be taken out.
