@droftarts Thx, that was is. I really thought i had the right firmware. After updating it works instantly.
I do have now the end stop plug in not working anymore;
Failed to start plugin
Loading chunk EndstopsMonitor failed.
(missing: http://192.168.178.96/js/EndstopsMonitor.0416dadf.js)
But i only used it when setting up the machine. Now i'm going to be busy with the Input shaping plugin. Wish me luck and thanks for the help.
