The rubber coating that was replaced on the drum has seams resulting in uneven spots. Tried to rub them down. Each of the slightly worn drum ends for the axle rod may not be flush and true either. Rod rolls without wobbling. Not much can be done, although wrapping a drum with Saran Wrap came to mind. It is what it is.
You're right about that. Your only option, IMO, is to purchase a replacement drum or forget about using the SuperSprint for cutting.
The plotter speed had been 100%, but by slowing down in device settings to 25 or even 16% the blade cuts in the intermediate vinyl are going thru to the carrier alot better. Some horizontal cuts are going all the way through
Slowing the plotter down will not result in changing the fact that you are attempting to cut evenly on an uneven surface.
The 24" plotter you mention Fred, is it the Tempo 600 friction plotter? Any good? Seen one for about $1800 with Omega CS.
I was referencing the typical cost for any name brand 24" plotter such as a Gerber, Summa, Roland or Graphtec. The last time I heard a price for a Gerber 15" drum was about ten years ago and it was in the $800 to $900 range. My guess is that at this point it is well over $1,000 and is approaching the cost of the brands mentioned for an entire new plotter.
How does your friction adapter work?
It worked by adding two silicon rubber rollers to replace the one bail roller and the ability to add a downward force on them sufficient to make full contact with the vinyl. The last manufacture of a Scrappy™ was in 1992 and the last unit was sold in 1994.
