Cura 2.3.1- Over ride the 150 mm/s limit

[lasakro 0]

In which file can I find the 150 mm/s speed limit so that I can increase it?

Afaik there's no limit but just a friendly warning in orange. The speed settings are hidden by default, go preferences to unhide it.

Then how do I get the completion clock to correctly calculate and remove the orange over 150 mm/s? I have not timed a print over 150 but I will tonight.

Well I don't know what's your machine, system or anything else (since you didn't post it) so I don't know how can I help you on that. For speed settings, you can pretty much anything your machine can handle. Speed is finite, as much as you can't extrude 150 mm/s of material without a big loose in quality.

It will be interesting to see your results of your timing against the Cura estimate.

The thing to note is that printing 3x faster isn't going to result in printing in 1/3 of the time.

I can change the print speed in Cura and all the other Speed settings, and the estimate print time does go down but not a lot as there are other factors that affect the time as well:

Jerk

Acceleration

First Layer Print Speeds

Retraction Distance and Speed

Combing

Rafts, Brims, Supports, etc.

Z-movements

If the Cura estimates are way off from the actual print times (> +-10%), take a close look at Jerk and Accelerations settings in your printer compared to those in Cura. Matching those up will help close that time gap.
