Replicator 2 with HBP - Preheats bed always. SOLVED

I have a replicator 2 with a HBP installed.

The issue I have is when ever I go to print it heats the build plate up to what ever the preheat settings in the firmware are, Instead of S3D controlling the temperature I have to change it in the preheat settings on the control panel of the bot itself.

I know this must be just a setting somewhere so any help would be appreciated.

Re: Replicator 2 with HBP - Preheats bed always.

Go to Tools > FIrmware Configuration, and under the X3G tab, make sure you have Replicator 2 with HBP selected. In your FFF Settings, add a temperature controller in the Temperature tab, and make sure the type is heated build platform.
Then in your starting G-Code, find where it says:

M104 S[extruder1_temperature] T0
M133 T0 ; stabilize extruder temperature


and insert this line above it:

M140 S[bed0_temperature] T0
M134 T0 ; stabilize bed temperature


If you dont want to set up the profile yourself, I have included one.

Thank you for the reply. The actual problem was in the firmware settings of the bot itself.

Utilities > General Settings > Override GcTemp OFF

Mine was ON which causes the bot to ignore the G-Code temperatures and use the ones in the preheat menu.

Re: Replicator 2 with HBP Settings

For those just starting out trying to setup S3D with a Replicator 2 and HBP...

Racked my brain for a while on this so let me give my settings for any new people who have this setup.

First setup your bot using

HELP > Configuration Assistant > Makerbot Replicator 2

then...

Tools > Firmware Configuration
X3G Tab > Machine Profile > Replicator 2 with HBP
Toolhead has Heated Build Platform > A checked


then...

Main Window > Processes > Add
Temperature Tab
Add Temperature Controller
Name it something like: Heated Build Platform
Temperature Identifier: 0
Temperature Controller Type: Heated Build Platform
Set temperature by double clicking existing temperature under Per-Layer Temperature Setpoints.


Now this one is personal preference... By default S3D heats your build plate up before it moves your extruder to its starting point. If that does not bother you then ignore the next step.

While still in your processes tab...

Scripts Tab
Starting G-Code Tab


Look for

M104 S[extruder0_temperature] T0
M133 T0 ; stabilize extruder temperature


Then the line before it add the following...

M140 S[bed0_temperature] T0 ; heat build platform
M134 T0 ; stabalize build platform temperature


So after you add that it should look like...

...
M126 S[fan_speed_pwm]
M140 S[bed0_temperature] T0 ; heat build platform
M134 T0 ; stabalize build platform temperature
M104 S[extruder0_temperature] T0
M133 T0 ; stabilize extruder temperature
G130 X127 Y127 Z40 A127 B127 ; default stepper Vrefs
...


Ending G-Code Tab

Look for...

M104 S0 T0 ; cool down extruder

After that line add

M140 S0 T0 ; cool down heated build platform

So it should look like...

...
G1 Z155 F1000 ; send Z axis to bottom of machine
M104 S0 T0 ; cool down extruder
M140 S0 T0 ; cool down heated build platform
M127 ; stop blower fan
...


Thats it you should be all set.
