    So I am having problems with the right side cutting all the way through. The left side is perfectly weedable.
    I can have pressure all the way up and it still wont cut through. I have replaced pen holder and strip.
    I have paid close attention to the belt for the motor and everything seems consistent all the way through.
    Any other ideas?

    I know you replace the strip. But when there is no material on the machine. Does it feel like it is higher on the right side than the left? It's pretty easy to tell you just take a piece of vinyl and try to run it through. See if it hits the cutting strip on one side but not the other.

    Sometimes glue residue or something else could be under the Strip, and even if it is a new one, if it's not installed perfect, it would cause even issues.

    Is the plotter sitting terrifically unlevel?
    How long has it been doing this? How wide is the material this is happening to? Only 48" or even on 24"? Are all of the rollers set to the same tension(this doesn't seem to have any impact, but worth a look)? Do you have the bladeholder in the proper position, and minimal blade sticking out?

    Completely level.
    About 2 or 3 weeks. Plotter is 2 or 3 years old. All sizes. 18"-48". All same tension, I assume. Never messed with them since a tech hooked everything up. bladeholder and blade is good.
    I was cutting some 3M EG with laminate the other day, had pressure ALL the way up, and blade sticking out extra far and it still didnt cut through. I had to finish them on the other FC we have.

    I guess I should mention one of the roller assemblies are "loose" meaning even with handle up, you can still move it.
    But that has been loose for a while now and this problem is more recent.

    So try taking 24", and just use two of the rollers (or 3 if you have 4 total rollers), leave the extra roller just like it would be on wider material, then try to plot something within that 24" region. If it cuts fine, I'd wager the roller not holding the material down is just as detrimental as the cutting strip being raised up, especially on thicker materials.

    On the back side of the Plotter you have a lever for Each Roller.
    Make sure all are Down. ( sorry I forget what they are called)

    If one or two is in the Mid or Up position you will have issues.

    If all levers are down, then get it serviced.
    A Service call is $300 or $400 so what, that Graphtec is your Race Horse.

    I had what sounds like exactly the same problem and found that I was putting the blade holder into the tool holder incorrectly so that the "flange" wasn't holding it down. Hard to explain. It should have been common sense, I guess, but I was following the user manual directions. I think the directions are misleading and/or incomplete on that point. SO, if you're a "read-the-directions" type person like I am, maybe this could also be your problem ;-)

    I used to have an employee that could never get the knife put back in right. He'd pen a pattern, then I'd go run 10' of translucent vinyl, only to throw it away because 75% was not actually cut through, because the f*cking kife just got pushed upward at one point.
    I don't think that's the issue here if it's consistently not cutting one side, but worth a look!

    I have gotten to the point where i think this is an electrical issue. Nothing else makes sense. So, I had this bright idea to do a factory reset. It didnt help :(
    Im wondering if its the mother board

    So, I just fixed the problem. Its weird though...
    All i did was move the pen to the other slot in the holder and brought the blade out a tad. Its cutting like it should. At least with thin black vinyl.

    Like the left side is still cut fine, right side is unweedable? Or it does not want to read registration marks?

    Yes. I have to move the needle back into the proper place on the holder or it cuts off. In doing so, the right side still wont weed. Exact same spot. Every. Time. Blows my mind.
    I have a tech coming next week with my new printer.. i am going to get him to check it out.

    I think you can put the blade in the other slot, and just adjust the offset appropriately. That or selecting the different tool position under the condition>assign tool> then change it to tool 3
