Printing race car style...

[DaHai8 74]

You know how race cars go really fast on the straightaways and then slow down to go around curves? The tighter the curve, the slower they go...

It would be sweet, I think, if Cura could do the same in slicing. I think it would really improve prints.

Some sort of 'speed factor', or deceleration rate to be applied to curves that slowed the print based in the tightness of the curve. Then resumed full speed on the straightaways.

I know: nice idea / hard to do...

Just a thought.

Cheers.

Hi there,

I think it already does this. That is, the Marlin firmware does it. But I also think it happens too fast for us to see/notice it.

I am not expert. I am sure someone wiser than I can answer with more certainty.

Like krys said, the firmware does this for you. I don't know what printer you have but for the Ultimakers you can change the acceleration and jerk settings to change how aggressively/smoothly the head moves.

Hmmm...

Printing at 50mm/s circles of 5mm dia, the print head spins around like a crazed tornado!

So my screw holes are not the greatest.

My settings are as follows:

 

Accel: 300Vxy-Jerk: 20Vz-jerk: 0000.40Ve-jerk: 5

 

Its a Prusa I3 style printer: Aurora A3

Any suggestions on settings to where to read up more about this?

Maybe I need a firmware upgrade as well? I know it Marlin, but I think its really old because it won't reply with the firmware version and Tune / Flow doesn't seem to do anthing.

I've been hesitant to change it before for fear of screwing things up..

P.S. I "jerked" around with my settings and set the xy jerk to 12. That seems to make it calmer around corners. But I also set my Accel to 500 and now I can't set it back down to 300! :(

Maybe 500 will be ok....
