Cura 4.1 generates wrong gcode command causing the printer to stop printing

[BenMens]

I have a stl that prints fine using Cura 4.0. When using Cura 4.1 the printer stops at layer 50. In the gcode I see a strange value that I marked bold below.

G1 F17987547480000 Z5.2

Hi @BenMens ,

We're aware of this issue. Printers that don't have a value set for maximum z speed get the maximum speed possible, light speed. Needless to say, this confuses some printers that didn't anticipate for relativistic speeds.

For now you can work around this by manually setting the maximum z speed or disable z hop or adjust the profile of your printer.

This has been fixed for 4.2 (and it's a duplicate of https://github.com/Ultimaker/Cura/issues/5753)
