How long do you Pre heat for MINDA  

RE: How long do you Pre heat for MINDA

This is the start G-code that works for me, 80 seconds in the middle of the bed:

G90 ; use absolute coordinates
M83 ; extruder relative mode
;added for better Z axis control
G28 ; home all
G1 X100 Y100 F4000
G1 Z1.5 F50 ; park position
;end of added section
M104 S170 ; set extruder temp for bed leveling
M140 S[first_layer_bed_temperature] ; set bed temp
M109 R170 ; wait for bed leveling temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
;added
G4 S80; wait 80 secs when heated up
;end of added section
G28 ; home all without mesh bed level
G29 ; mesh bed leveling 
M104 S[first_layer_temperature] ; set extruder temp
G92 E0.0
G1 Y-2.0 X179 F2400
G1 Z3 F720
M109 S[first_layer_temperature] ; wait for extruder temp

; intro line
G1 X170 F1000
G1 Z0.2 F720
G1 X110.0 E8.0 F900
G1 X40.0 E10.0 F700
G92 E0.0

M221 S95 ; set flow

I've seen some using a longer preheat. I'm thinking that the MINDAs vary in temperature sensitivity. Some don't need a heat up at all. Some need a longer heat up. For some, this does not work no matter how long they preheat.

I used to for around 80 seconds, but now I print from printer cooled down instead, and get pretty consistent results.

I've made a note of the cold and hot live Z value. It works pretty good most of the time.
