Hey everyone, thank you for the responses! I'm sorry that I didn't respond right away. I thought that I had set this thread up so I can see the responses, but clearly I didn't. And I have been busy doing other tasks for the company, but I'll try to respond to everyone that has replied to this post.
Yes, both pinchers are on the the roller, at least to the best of my ability. The right one clicked when I placed it in the correct space. It's the left side I'm having difficulties with because in order to fit the width of material in, the left one when it clicks in is too far to the left for the material. I'll include some better pictures that should appear at the bottom of the post.
Would I be able to check that in the Summacut Control program or the GoSign program? Or would be on the machine itself? I apologize for not knowing how to do this!
The right pincher as far as I know is in the right spot as I heard a little click when I moved it, but I have a funny feeling the scanner on the right side of the machine may be out. I talked to one of the owners and apparently he thinks that as well. Even when I put the longer length material (around 28') and put it through the GoSign program, it'll put the job slightly to the left and won't use the material as effectively. I'll have to call Summacut and see what they can do to help.
I'll check the blade and see if there's any gunk build-up, but I also could be using too much force. It was set to 150 gr, tried it on a job and it wasn't strong enough only for me to go up to 160 gr, which was probably the problem lol. So I'm going to set the gr to 155 gr and see what happens. It's a pretty thick vinyl, so that part is going to take me a bit to figure out what the best cutting pressure is.
I'll have to look into the machine control and see if I can play with the width! I had no idea the machine could do that, but that's why I'm a newbie lol.
When it comes to the third pincher, I'll see if we can either get one, or there could be a third pincher lying around somewhere. As you mentioned it's a pretty thick vinyl, and it might help keep the material from moving around all over the place.
Thank you guys so much for your responses and advice!
