Custom start gcode

Hi folks...

I am looking for some gcode guidance.

On my Mk3 I had a custom start gcode which did essentially two things..

1- chirped when the print was initiated

2-Only heated the hot end up to 140c prior to bed leveling to prevent errors and mess

3-heated the bed up and then waited for a pinda temp (obviously not needed for the mk4)

4-perfomed bed level

5-heated the hotend to first layer temp

6-chirped

7-purge line

8-moved on to print gcode

 

I am trying to do something similar with the mk4.  To included the chirp at beginning and at print start as well as only heat the hotend to 140c until just before purge.

Unfortunately I am struggling with the order of things.
I am wondering if changing the underlined values to 144 : 140 will accomplish the no ooze I am looking for...

M104 T0 S{((filament_notes[0]=~/.*HT_MBL10.*/) ? (first_layer_temperature[0] - 10) : (filament_type[0] == "PC" or filament_type[0] == "PA") ? (first_layer_temperature[0] - 25) : (filament_type[0] == "FLEX") ? 210 : (filament_type[0]=~/.*PET.*/) ? 175 : 170)} ; set extruder temp for bed leveling

M109 T0 R{((filament_notes[0]=~/.*HT_MBL10.*/) ? (first_layer_temperature[0] - 10) : (filament_type[0] == "PC" or filament_type[0] == "PA") ? (first_layer_temperature[0] - 25) : (filament_type[0] == "FLEX") ? 210 : (filament_type[0]=~/.*PET.*/) ? 175 : 170)} ; wait for temp

Also, the chirp command "M300 S40 P10 ; chirp" elicits no sound.  Maybe the buddy board has no speaker?

 

Thanks in advance!

Yes, the suggested temperature changes will work. And as for chirping, the MK4 chirps very quietly, almost inaudibly. People have complained about it to the developers several times, but they probably have a guy with ears like a bat who can hear the grass growing and thinks other people can hear that way too.

I have good hearing for my age (over 50) and I able to hear my MK4 quite well. On the other hand I print in quite room. For some noisy workshop MK4 should have much louder buzzer IMO.

I agree with you. The fact that the printer beeps is a sign that it requires the attention of the operator because some error has occurred. Therefore, IMHO, the printer should roar pretty loudly to attract the operator. If someone has good hearing, they have the option to turn down the volume.
