Hello everyone, I made a project with MK3-ET Ethernet connected control card. But I have a very small problem. Even when I send a one-line command like G1 Z10 F10, it stops very briefly in DRO for 2-3 seconds. When this pause occurs, the units/min part changes constantly. However, if I do not select the control card when I start Mach3 and continue with No Device, there is no pause and the units/min part remains constant.
I tried on a more powerful computer and different Mach3 versions, the result is the same. Right now I am only testing with the control card and power supply, I do not think there is any interference.
Does the motion ‘stutter’? I wouldn’t pay too much attention to what the display is doing. The commands sent to the Mach3 controller card are buffered and therefore decoupled from the rendering on your computer. All of the motion control is performed on the controller board itself and should be continuous (at least a buffer’s worth of commands).
Thank you for your help. I tried different versions of the control card plugin yesterday. The stutter and pause on the Mach3 screen differ depending on the plugin version. I get the same result on the Mach3 screen whether the version that stutter or not. It leaves a mark, although it is not very noticeable at 5mm intervals.
