Amazing speed of TinyG Ultimaker!

Recommended Posts

Posted · Amazing speed of TinyG Ultimaker!

This is the video on youtube.

 

With TinyG driver, motion can reach 50,000mm/min! Unbelievable, I'm thinking whether could I modify my Ultimaker with TinyG firmware...

Sometimes it's fun to just do stuff for... fun ;) Also, I don't think it's bullshit. Try changing the max acceleration/jerk/etc and then move the printhead around, it gets pretty scary.

I just think maybe the TinyG can help me to get a great improvement in printing speed, but also I doubt how to keep an acceptable printing quality is a problem...

Hmm well the video says accel increased to value of 50,000mm/min sq.

Which is actually more or less identical to standard accel of around 900mm/sec sq, just multipled by

60 to make into minuites for some reason....

Dont know what the standard "jerk" is set to....

(Apologies for 1st post, I violated the golden rule of internet forums "never post messages after drinking")

I think the default is 3000mm/s^2. And I've printed with 9000mm/s^2.

At the video I'm not seeing "amazing speeds" compared to anything that Marlin can do. If you want "fool around", enter the motion menu, set acceleration from 3000 to 9000, set the speed on the main menu to 999%, play a bit with the maximum feedrate setting (also in motion) and then tweak the jerk setting so you won't miss steps. Marlin has no issue achieving these "amazing speeds" at all.
