There are many things that can cause communication issues between a cutting plotter and computer. We want you to check a few settings in SignCut first. Check so your settings matches the image below here. Now try to cut again. If it still cuts a diagonal line please go through the steps below to troubleshoot further.
Memory buffer
Your cutter has a built-in memory which processes the data before cutting it out after receiving it from SignCut. Sometimes this memory gets full if the machine doesn't clear it properly. This sometimes makes the cutter stop or start doing random cuts. If the cutter manages to empty the space it then goes back to cut the new data but the cut has been destroyed. We have a setting in SignCut that in some cases solve this. If you click Cutter in the settings menu in SignCut and then set curve resolution to around 50% it will make the amount of data sent to the cutter smaller. This will not effect the cutting result. What it does is that it removes unnecessary nodes in the file.
Communication loss
Depending on if you have a desktop or a laptop computer there are a few things to think of.
Desktop - Make sure the cutter is connected to the back of the cutter as those USB slots have a higher amperage which makes the connection with the cutter more stable.
Laptop - Make sure the cutter is not connected to a USB 3.0 slot. Many cutters do not have support for it and it effects the connection between the cutter and computer.
USB-chip or USB-driver
Make sure you have the latest USB-driver for your cutting plotter and that it is compatible with your operating system. Normally you get the proper driver together with your cutting plotter on a CD or the reseller has it available on their website for download. If you can't find it you can always ask us and we will try to help you locate it.
If none of this steps removed the communication issues you are experiencing then we recommend you to use a more stable connection between your cutter and computer then the USB-connection.
We recommend you to use a serial cable with a serial to USB adapter with an FTDI-chip in the adapter since it is a more reliable USB-chip. We've tested it with good results. FTDI serial to USB adapters are available online at Ebay and Amazon and also in some local hardware stores.
We recommend you to not get an adapter with an USB chip that uses the Prolific driver as it isn't as reliable. If you want to check if you have found a good adapter you can consult one of our agents in our livechat.
