      After Further Testing, It still Does the Same thing, But Not Every Time. If you have any other ideas

        Combined Movement on this CoreXY Duet 3 Expansion 1XD Boards Driving Nema 23 Closed Loop Stepper Motors Seem to be the Issue.
        This is Fine:

        G1 X100
        G1 Y100
        

        This Does not work:

        G1 X100 Y100

            Firmware 3.2.2: G1 X100 Y100 Moves about Half X and Y. While Printing, It Layer Shifts Continuously on the same Layer.

            But This Works Fine For some reason:

            G1 X100
            G1 Y100
            

            Firmware 3.3Beta1 The Machine Refuses to Home. It wont Recognize X or Y on the Expansion 1XD Boards. (Both 1XD Boards were also Upgraded to 3.3Beta1)

              In the Image, The Printer is Continuously Layer Shifting Mid Layer In a Diagonal Fashion. These are Nema 23 Closed Loop Stepper Motors, Driven from 2 Duet 3 Expansion 1XD Boards for X and Y On a CoreXY Machine. Have to Use 3.2.2 Firmware Because 3.3Beta1 Will Not Home.

                Layer shifts when using external drivers are a sign that the M569 T parameters are not right. Don't just guess, get the specifications for minimum step time, minimum step interval, minimum direction-to-step setup time, and minimum direction-to-step hold time needed by the drivers.

                I'll reply regarding the homing issue in your other thread.

                    I took it right from the Wiki Page.

                    "b This is setting T0:0:0:0 this allows the firmware to generate short pulses. in measurement these where no shorter than 0.7ns."

                    But I also Tried Removing it aswell, Leaving the Default.
                    "On the EXP1XD board the default is T2.6:2.6:2.6:2.6"

                    When I get home later tonight, Ill play around with Timing and see what happens.

                      @Toastinator you need to look at the datasheet for your drivers to determine the timing required. I suspect it will be higher than the 1XD defaults as well

                      Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is

                        The Datasheet I was given does not Mention any Required Timing. It just says it accepts from 0-200Khz Pulse Frequency.

                        JSS57P2N Instruction manual

                        After Changing Timing to T5:5:5:5 and T10:10:10:10, It Seams to Move Fine, But there is Some Type Of error Accumulating. (Or somthing else, lol)

                        Yesterday, I was Getting Homing Errors. Today Without Changing Anything, Its Homing Fine, But Not waiting for the Hotend to Heatup before Moving. And Look at this Picture of a No Infill Cube. The Infill Filled in Slightly Wavy at the Bottom.
