I would like to find a model or a g-code file that would produce some goos testing for filament types.
I have tried some temp towers that don’t seem to be changing temps during model production. Worthless!
I would like to be able to plug in a g-code that would ramp up temps, or make adjustments to test out filament types. PLA, PLA+, and PETG.
If you’re downloading an stl and slicing it with Luban, it won’t change temperatures at the layers. That’s up to the slicer, and Luban doesn’t have that feature. If you’re downloading gcode, you can open the file and verify that it is changing the temp by searching for M104 and M109 (set nozzle temp and wait nozzle temp respectively). Here’s what I see in the Temp tower I downloaded from the forums:
I got those files from xchrisd’s 3D Print Guide, section 4. If you want to do it yourself, you’ll have to edit the gcode to manually insert the M104/M109 commands at the appropriate layers. I’m sure there are temp tower generators online somewhere, but I haven’t tried any.
Or at least I used to, now I make my own because there’s bridging issues and layer slowdown problems I was experiencing. Simplify3D has an easy way of changing settings at certain heights, and so does Cura using the ChangeAtZ script
Follow Brent’s advice and go deeper down the rabbit hole, that site is brilliant.
Here, I keep needing to recreate these, theres a PETG from 270 to 205 (mine spaghetti’d at 210 on fast) for the snapmaker 2, A350, it’s in the center of my bed so shout if you want me to move it for a smaller machine.
Then there’s a PLA tower 230-190 for the Snapmaker original. gcodes.zip (3.2 MB)
