Eddy. I'm not sure if If it's running at its designed optimum as I have not had time to test it. I ran some code to cut a sign from 6mm mdf last night. Like the photo of the one I have posted here before. It seemed to not miss any steps it cut very clean and quite fast. The sign was about 10inch long and 5inch tall. It had no problems and took about 20 mins, but I only have the plunge set at 1mm so it took 7 trips to complete the final cut out. but that was planed and expected. If you let to know who I should test its performance I will gladly carry that out for you.
