Initial heat-up runaway protection temperature_control.bed.runaway_heating_timeout
this only allow maximum of 255 sec, anything above 255 wont work. my bed definitely take longer than 255s to reach desire temperature.
if i set 600, the bed will heat up like about 30-40sec and HALT.
firmware limitation?? bug??

This is a firmware limitation. Do it by steps : M190 S20 then M190 S40 then M190 S60 etc, that should work.

3

Add in every gcode till it reached target temperature?

4

I’m not sure I understand

5

I’m using cura2.1 as my slicer and copy the gcode to printer via sdcard. I’m not quite sure how to do the m190 s20, m190 s40 as u suggested.:blush:

6

google for “cura startscript M190”

7

i cant edit m190 in cura2.1 …dafault m190 will be the first command

@Rene_Jurack ​ can u give me some guide on how to add m190 to cura2.1 slicer? Or point me to the right site?
I can edit the gcode manually but it is possible to add in to my cura?
Cura seem to auto add m190 s{print_bed_temperature}, I can’t add anything before that auto generated m190
