Simplify3D User Forum

Hi all,

I have a Wanhao 4s printer, in Simplify's3D have set temperatures for bed and extruder, but these are not taking over at my printer.
Set for example the first layer temp to 220C and after layer5 to 200. I can only adjust the temp at the control panel of my printer in preheat settings. So I have to change that everytime I change from filament or layer height settings.
Before Simplify3D I used Repg and the Gcode temp settings were send to the printer. What am I doing wrong?

Why don't you post your factory file (file --> save factory file). Then we can verify you are using the correct settings.

If you export the x3g and gcode files from your settings, you will see the appropriate temperature commands in the file. Open the gcode file in a text editor and look for the "M104 S220 T0" on layer 1 and then "M104 S200 T0" on layer 5. Those commands then get converted into binary format for the x3g file. I also checked that using a hex editor, and it also contains the appropriate temperature commands. So the software is creating the right files with the correct commands in them.

Now, how your printer chooses to respond to those commands is another matter. For example, I believe your firmware allows you to override the temperatures from the x3g file using the settings from the LCD panel. This way you can print the same file 5 times, but adjust the temperature using the LCD panel without having to create a new file each time. Nice feature, but it will disable any temperature commands in the x3g file. So you should verify that you have that option disabled in your firmware.

Thanx Joe, I found the setting in the firmware. GCtemp override set to off.
Fixed the problem! Thanks for your great help and quick response!

Only some extruder related problems to solve and I'm off

just wanted to say thanks for the question and answers. I was having the same problem. Found this thread quickly and solved it. I had never had a problem with the default override with other software, so it would have taken me a long while to figure that one out. THANKS!

I'm having the same problem. The "enter" or "M" key on my Replicator 2 stopped working so I can't execute anything at all from the lcd. So I connected to the USB port so I could load the .x3g from the sdcard and just print. I plan to disconnect from the machine once it starts the job and pull the USB out of the bot because I was advised to do so. I can't set the temp, the software doesn't set it. I can not navigate through my firmware on my bot because I can't hit the "enter" key to proceed through the menues. Is there something I can do? I don't have a way to change the firmware settings unless it can be done in software over the USB connection. If it's at all possible, I'd like to extract the gcode from the .x3g, change the line for the temp, then put it back together so I don't have to manually change anything. Can that be done if nothing else?

Sounds like you need to get a new LCD panel

I'm not sure how you can disable the firmware temperature override without it. You might be able to reset the EEPROM and completely reflash the firmware, but I'm still not sure how you would do some of those things without the LCD...

Have a search on YouTube how to solve this problem. It is probably a grounding issue. You have to scratch some green or blue protection material from the print where the nuts make contact with the frame. Had this also, but then with strange symbols in the LCD

Hi ,

I am having the same issue with Makerbot Z18, the gcode is correct and shows the change in temperature, but the machine doesn't take it, is there any way to fix this?

Thanks
