the M2 is at the shop about a mile from home. i use Octopi and can monitor the printing via the webcam which watches what's going on. I use VNC so can watch it from home. If there is a problem, I can shut down the print, which then does a soft shutdown on the printer. my 20 hour print has about 4 ho...

thank you sooooo much.

I'm using the MakerGear Forum recommended PETG setup for Simplify3D with my M2/E. The printer is not enclosed and the ambient temperature in the shop is 75F. Setup above calls for turning fan on after printing the first layer, using 87C for bed and 247C for extruder. I'm used to getting a little lif...

I agree that reducing heat may cause the extruder not to be able to melt filament quickly enough to keep up. a ducgted fan does eem a good fix. keep us up on what you are doing.

best,

Thanks for posting on this. at the faster speeds, would you think that reducing extruder temperature a bit would be constructive?

thanks TomR. I look forward to discovering where I've messed up my settings so thing take too long to print. more to follow.

HI TomR, Did you seal the PetG part of the mask, and if so with what? Also,in full knowledge of the imposition of asking this, is it possible/easy to share the first part of your g-conde with us? Simplify3D gcode contains all of the settings in the first several page equivalents. Having this informa...

Hi TomR,
this looks like a much better design than what I did. What did you slice it with, and print?
thanks for alerting us to this.

i printed the straight from the box Montana Doc mask. Of course it didn't fit well. I think I can make a much better fit by varying the scale in three axes, not forgetting to also adjust the scale of the "grille." I fussed with the settings to print PETG but it still took 5 1/2 hours to print the ma...

Jeff, I should add that my choice of PETG is not for its efficacy, to use a medical term of art, but because it's what's in the printer and I have (finally) a setup which produces consistent quality. PLA could be a better choice. If they lock down St Petersburg, I may not be able to get back to the ...
