It sounds like maybe you are trying to run the compressor at a speed so that it provides the desired pressure and volume without using an accumulator tank. This means running the compressor at low RPM and high torque continuously. Have you checked that you can do this? My guess is that you'd

Hi Peter; It looks as if the inavailability of the high voltage op-amp I was going to use will make me use just a part of the a/d range of a 7i76D first 4 inputs. And, the relative lack of data for the MAP sensor I have two of, might be a limitation too. The data is sparse, but what has me

[Emc-users] Why not have a trivkins setup with a slave axis

2022-04-15 Thread Marius
Hi Just wondering why is it not possible to have a standard three axis trivkins setup with a possibility to slave a stepgen to any one of the axis. So it is not part of the kinematics just slaved to the command signal of any axis? It is done in Mach3 and I have installed many machines that
