Help with stringing after calibrating flow

Recommended Posts

Posted · Help with stringing after calibrating flow

I've been trying to dial in my Cura from over extrusion issues. I checked my E steps, and found it was under by a few mm, Corrected that. Now I've been printing a calibration cube trying to get my wall thickness right. For whatever reason, It didn't reach the right thickness until my flow rate was around 40%. That seems crazy to me. A side effect of getting the flow rate going that low is now I have a lot of stringing. More than I've ever had an issue with before. I have tried to adjust my retraction distance and speed but I haven't noticed any changing in the stringing. I also dropped my print temp down in an attempt to fix that. I'm sort of at a loss without starting from 0 and trying to re-calibrate it all. Not that I would be surprised. 40% flow rate seems insane to me. If anyone can offer advise I would appreciate it.

 

Printer is a Maker Select v2 Microswiss .4 nozzle

 

Current default settings except for .2: flow rate% 40 Retraction 1.4mm Retraction Speed 40mm/s Print speed 60mm/s

 

Printing with Solutech PLA 190 Hot end

 

I'll provide any more information I can if it will help

I don't know your printer, but a flow of 40% is not normal. So I guess you have done a mistake with your E steps and it is too high. Because when you set a lower flow, you basically reduce the E steps more less again from the software.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
