Slic3r seems to revert to defaults every time I start a prin

[pappahymen]

I have completed my construction of the Rostock Max as per the manual and have followed it to the letter for the software setup as well but I cant get Slic3r to work properly. I am trying to do my first print the calibration cube but every time I hit start job, the printer drops the extruder temp to 200 degrees and wont start printing until it hits there. I have tried many times to create profiles and configurations as per the instructions but I haven't been able to. I have them set up but on the Slic3r page or Repetier the configurations are grayed out and I cant select anything. Anyone had a similar experience? I tried to uninstall Repetier and re-install it but that has not helped. Any assistance would be greatly appreciated.

Look at the generated gcode file. The header looks like this for Slic3r generated code:

Code: Select all

Notice where it sets the temp on the 2nd code line "M104 235". If you are not seeing the values you set, then you might not be overwriting the original file? Report back.

cheers,

Thanks for the reply. I checked the g code and it is definitely overwriting with 200. I am including the G code as well as A screen shot because I cant select the print setting, printer settings or the extruder 1 settings as they are grayed out.

Run Slic3r freestanding and save to a different file name to make sure you are actually writing the updated file. I seem to recall that when you tweak Slic3r parameters in Repetier Host you need to save or reload or something. Maybe someone here will remember, I've been slicing in KISSlicer so I've forgotten all that!

I opened the Slic3r independently and changed the settings and exported the gcode. I opened it up and it still says 200 degrees. I think I will try another slicing program. Hopefully it will work better than this.

Now that's odd! I'd verify the new temp values and shutdown and relaunch slicr. You do know that you need to click the little disk button to save a configuration correct? Try saving it with a new name too.

Ok it seems like renaming everything again and exporting the gcode worked this time. I will test this and hopefully I am able to print something finally. I will follow up with my results.
Thanks again.

Can you post a screen shot of the Slic3r configuration window that shows the filament temperature?

I was finally able to print after exporting the independently generated G code. Now all I have to do is fine tune the printer to get rid of some problem areas with the printing. Thanks for all the help. But that will have to wait as I have to leave the country for a few days.
