DWC Connection Instability

[SonnyD1]

Does anybody have any idea why my DWC keep losing connection? It doesn't interrupt the print at all. It just disconnects and then reconnects for no reason.

@SonnyD1 in DWC, try changing the number of AJAX from 2 to 4

[SonnyD1]

@jay_s_uk Ok I made that change. I'll let you know if the issue continues.

[SonnyD1]

@jay_s_uk Yea it's lookin like that did the trick. Thank you.!

@SonnyD1 upgrading your PanelDue firmware to 3.5.1 may help too.
