the max velocity for the latest scope picture is 8 and the DAC scale is 8.89 the machine was moving at 400 ipm with the original control 8 is the result of many attempts up/down to cause a difference in the feedback I just happened to stop with 8 as the number. This would be 480 ipm. I don't necessarily expect the machine to do this but it should be capable of doing VERY close to 480 ipm.
