So I am running into the occasion issue of stringing from the filament shaping that gets clogged in the Y splitter. Pretty sure this is due to the temp I am running the filament at but thought I would ask, anyone have any recommendations for preventing stringing so I dont go wasting a bunch of time on idea's that might not work at all?
Thanks
There are two basic types of strings. One is thin flat wispy strings caused by the filament being too cold against the side of the PTFE tubes.... the other is round thinning strings caused by the temperature being too high. When you're changing the filament, it's pretty easy to adjust the temperatures for them (either at the individual filament level) or directly within the Tool Change GCode itself. You can use the M109 gcode to raise or lower the temperature and you can use the R parameter to make sure it waits until that temperature is reached. So for example, M109 R200 waits for the temp to reach 200 (regardless if it was higher or lower) For Example: M109 R180 ; cura or prusaslicer - lowers temp to 180, waits for it to get there You can also use the M109 {temp variable} parameter of the slicer to restore the printing temperature... this {temp variable} will change depending on which slicer you're using... but for Cura it's: "{material_print_temperature}" and for PrusaSlicer it's: "[temperature_0]" (where 0 can be replaced with the extruder tool number.
Like this: M109 {material_print_temperature} ; cura (restoring active extruder) - or - M109 [temperatrue_3] ; prusa slicer restoring extruder T3 Bill
Cool, thanks for the tip. Im running some Jessie PLA (usually I run inland) and im noticing that the green color seems to string at the temp I use compared to the other colors I have feeding in so I might have to tinker with changing the temp values for just that extruder and see if it helps.
Edit: FYI, Im also using prusa slicer btw.
