@Slashee_the_Cow But the machine doesn't hold temperature with M190 🤔. The M109 in the start gcode does keep the temperature though? Is it because makerbot didn't write the firmware correctly? Also, is there a way to change the M190 that Cura generates?

@JoshofAllTrades Cura adds some g-code before the "Starting G-code" ;Generated with Cura_SteamEngine 5.5.0 T0 M190 S100 M104 S230 M104 S230 M116 M82 ;absolute extrusion mode The command M190 does heat the bed to the material temp in the cura setting, but that command does not hold the temperature. Does anyone know how to change the code generated by Cura?

Hello @MariMakes, By any chance do you know how to change the default Cura generated code for the MakerBot flavor? I also have a MakerBot Replicator 2X, but the code generated by Cura isn't using the (correct?) G-code that the machine use. ;MakerBot Desktop Output M136 (enable build) M73 P0 G162 X Y F2000(home XY axes maximum) G161 Z F900(home Z axis minimum) G92 X0 Y0 Z-5 A0 B0 (set Z to -5) G1 Z0.0 F900(move Z to '0') G161 Z F100(home Z axis minimum) M132 X Y Z A B (Recall stored home offsets for XYZAB axis) G92 X152 Y72 Z0 A0 B0 G1 X-112 Y-73 Z150 F3300.0 (move to waiting position) G130 X20 Y20 A20 B20 (Lower stepper Vrefs while heating) M109 S110 T0 M134 T0 M135 T0 M104 S230 T0 M133 T0 G130 X127 Y127 A127 B127 (Set Stepper motor Vref to defaults) -------------------line-break--------------------- ;FLAVOR:Makerbot ;TIME:2777 ;MINX:96.3 ;MINY:52.795 ;MINZ:0.3 ;MAXX:150.7 ;MAXY:94.497 ;MAXZ:38.3 ;TARGET_MACHINE.NAME:Unknown ;Generated with Cura_SteamEngine 5.5.0 T0 M190 S100 M104 S230 M104 S230 M116 M82 ;absolute extrusion mode ;begin the cura start G-code in the machine setting M136 ;(enable build) M73 P0 ;homing G162 X Y F35 ;(home XY axes maximum) G161 Z F15 ;(home Z axis minimum) G92 X0 Y0 Z-5 A0 B0 ;(set Z to -5) G1 Z0.0 F15 ;(move Z to '0') G161 Z F2 ;(home Z axis minimum) M132 X Y Z A B ;(Recall stored home offsets for XYZAB axis) ;move to start posistion G92 X152 Y72 Z0 A0 B0 G1 X-112 Y-73 Z150 F55 ;(move to waiting position) ;G130 X20 Y20 A20 B20 ;(Lower stepper Vrefs while heating) The Cura generated G-code uses M190 S100 which doesn't keep the bed heated after the temperature is reached. On the other hand, the original MakerBot slicer uses M109 S110 which does keep the bed heated at the set temperature. The M190 g-code is generated by Cura so I have no way of changing it. Currently the machine does: Heats the bed to 100C with M190 Heats the nozzle to 230C with M104 while the bed is cooling due to not keeping the temperature runs the start G-code, which I added the M109 to heat the bed again and keep the temperature goes on with the sliced g-code Any help is appreciated, Arthur

Hi, Just a Makerbot Replicator 2X, but there was some issue with the setting in cura. I used the printer profile found on cura for the replicator (not 2x version) then changed the start and end code to the gcode I got from exporting the gcode from the MakerBot Desktop. The issue I got is the bed heating up to the cura set temp then it will start heating the extruder while not keeping the bed temp. Then the machine starts the start G-code in the cura machine setting. Since I did use "M109 S110 T0" the bed did get to the bed temp needed for ABS, but is there a way to keep the bed at the cura bed temp? The G-code flavor is "Makerbot" if that is important. I went in the definition folder in cura to change the metadata of "r1" to "r2x" so there probably isn't an issue there. Thanks in advance if anyone knows.
