Hello,
I have a K2 Plus - No issues since the purchase (july25).
Since the last firmeware upgrade , I have a cocktail of issues ( jan26).
Firmeware version : 1.1.4.11
Is it possible to roll back the firmeware to old version ?
Anyone have the same issues since the upgrade ?

Exemple :
Sometimes I also get this message. In my case, simply resending the file solves the problem. But I also have another error. Every time I turn on the printer, I get the code AC0123. All these strange things started happening after the update.
Same for me. Could not finish any print. Printer just stuck at random points middle printing. Constant memory overflow from “master-server” process. And mcu just could not process commands on the go. System lod is exceeding 26 and free memory like 13Mb at stop point.
I was able to start normal printing on the latest firmware (1.1.4.11) after swapping X and Y motor pins (step and dir) in motor_control.cfg:
And if after that you still have issues with homing on X and Y axis you could try to add at the end of printer.cfg file this lines:
[motor_control]
x_param_stall_pos_err_rad: 0.016
y_param_stall_pos_err_rad: 0.016
This decreases stall position sensitivity and motors moves further to home position despite of some resistance.
