I cannot get simplify 3d to make the heated bed stay heated during printing.

It heats up just fine before printing, but as soo as the head starts to move, the HPB no longer heats. It must be a software problem, because the “preset temperature” dissapears from the LCD screen, just the actual (dropping) temperature remains.

I’m using a replicator2 and just installed the HPB. Oh, when using the printers’ preheat function everything works fine as well…

Hello, this is a Problem that Simplify has for a while now. You have to do several settings to activate the HBP. A year ago there was just one checkbox to activate. I will email you a file, please just import that to simplify. This should set your profile correctly for future prints.

Best regards

Edit your process then goto G-code -> firmware type chose Makerbot/sailfish, then under GPX profile choose Replicator2 with HBP.

I forget if I had to add the heated build plate to the Temperature tab at this point but have a look and if you dont see one there add it.

I did that already. Added it to the temperature tab too. But to no avail. It will heat up the HBP but as soo as the actual printing starts it stops heating.

Got your file and will try it out this evening.

If you do not want to use the file, most probably this is the problem:

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.

I just copied that from another thread.

Simplify somehow doesn’t do that automated at setup anymore. So even if you select Replicator 2 with HBP you have to add these lines by yourself.

Odd, worked for me.

I also done it with a custom profile in Firmware config with the GPX config set to rep2 with HBP.

Does HBP show up on the advanced process setting? If your using a rep2 profile if may keep it from being active. If so, choose a 2X configuration and then select Right extruded only. From experience I native that sometimes the HBP temp goes back to 0. But I just keep an eye on it before making x3g files. Hope this helps. I have a year experience with simplify3D.

Ive got the Replicator 2X and does the same thing…no problem in Makerbot Desktop…

Simplify 3d support sent me an fff file. Been working just fine with that. Thank you to all that replied and helped ! Oh, and totally happy with the HPB !
