I thought I had everything working; however, in my first test run, each axis moved a lot slower than expected. I'm using Estlcam to generate my gcode, which produces a .tap file that I load into OpenBuild CONTROL to drive my Blackbox. In Estlcam, I created a custom needle cutter tool to cut foamcore. I set the feed speed to 9mm/sec. But when I did a dry run of the gcode it took 30 sec to move 10mm. I suspect something missing in my setup of Estlcam. In looking at the gcode, I didn't see $4=1 anywhere, is this supposed to be in all my gcode? I'm not sure exactly what this command does or if it is the cause of my problem.
