pausing hot end during retract

[fast204 0]

Hello all. new to the 3d printing world for the most part so excuse me if I sound like a complete noob. The question I have is about pausing while retracting. I downloaded the newest version of cura last night and ran a simple print to dial in a new printer. What I am seeing is that the hot end stops during retractions, it did not do this before I started using the newer version. what setting am I missing?? any help would be great.

Thanks

You mean it cools down?  What do you mean it "stops".  Do you mean the feeder (the cold end) stops?

 

Maybe you should show a 5 second video of what you are talking about because I'm not following your description.

 

Also please post what kind of printer this is (it's okay if it's not an Ultimaker).

Sorry. Should have been more specific. The x y axis pauses for a split second while the retraction takes place then continues like normal.

Yeah that's normal.  If you want to reduce the pauses then increase the acceleration (and maybe speed) of your retraction.  How far do you retract?  Typically 1mm for head mounted feeder and 5mm for bowden printers.

 

If you can double the acceleration on the stepper then you can shorten that pause quite a bit.  I've gotten it so fast the retraction is basically just a click.

that seems to be the ticket, I completely overlooked the retraction distance. it was set at 6.5mm retraction at a speed of 45

I have the same problem as fast204. Im new to 3d printing, and I don't know how to adjust retraction acceleration. 

 

How do you adjust retraction acceleration?

 

Thank you
