Cura 4.8.0 ignores hotend temperature settings

Dear community,

 

Once the G-code, generated by Cura 4.8, sent to 3D-printer (Lerdge-based custom made), it ignores hotend temperature. What might be the problem?

Have you been able to print anything?  Within your gcode file should be an M104 and/or M109 to set the hot end temperature.  M109 is "wait for hot end" to get to temperature and the M104 merely sets the temp.  They need to be before any gcode lines with an "E" extrusion.  What firmware is the printer running?
