Thanks for the reply Robert. I have your feeder mod on my ultimaker 2 extended, its awesome!
There really should be some ability to speed it up if the system resources are there though. I understand when its slow on an old PC but im running a 5960x 8 core cpu at 4.4GHz with 32Gb of ram and a 1200MB/s ssd.. imagine what it could be like if it used those resources.
