A website estimates print time accurately from speed/acceleration/jerk
-
Shen - ran another test today. Your app predicted a print time of 2 hours and 10 seconds. Actual time taken was 2 hours and 14 seconds. Pretty darn good!
Good to know. The actual time always seems 5% slower than the predicted time. So I applied a 1.05 factor to the time estimation, the result became very accurate after that.

Cant wait to see this integrated into the web interface. This with a realtime gcode visualizer will bring it up to par with Simplify3D

Great work. Always wondered why the slicers didn't implement a feature like this. Having this in the interface would be awesome. I'd love to see a estimated column in the files section so I can have a quick look to see how long time it would use to print a certain item.

that is a great idea +1

yes, the idea is great, but…
everytime you go into the files folder the duet has to transfer the complete gcode to the web interface, so that it can calculate and display the estimated print time. If you have several large (>10MB) files, it can take some time. Are you sure, you will wait every time several 10s of seconds for the page to load?I think a button for every file you can click and the print time will be calculated and displayed in the column will be better,
All things have pros and cons.

I have it in mind to have the firmware run gcode files in simulation mode when the printer is otherwise idle, so that it can build up a database of how long each file will take to print. But that won't happen until I have converted the firmware to use an RTOS, which in turn means that it won't be implemented for the Duet 0.6 or 0.8.5.
DWC already maintains a cache of data about gcode files on the SD card. So a facility whereby you can ask DWC for a print time estimate and it runs this program to generate one would work quite well, because the result could be added to the cached file information.

Just checking this (the page is awesome!) I'm not quite sure about what parameter goes where…
Maximum Speed: M203 ; Set maximum speeds (mm/min)
Print Acceleration: M201 ; Set accelerations (mm/s^2)
Travel Acceleration: M201 ; Set accelerations (mm/s^2)
Jerk: M566 maybe??Can someone confirm?
Regards

Indeed.
I tested this calculator for several models I printed, with print time from 30[min] to 4[hours] depending on the model, and the results were very accurate, within +-1[min] which could be the time of hotend heating.
So, thanks for the great tool.
I hope it will be implemented in DWC. -
In my case is not accurate, that's why I'm asking if the values I'm using are the right ones… the jerk (is M566 then?) seems not to be OK, it failed in a 6h print in more than 1h... :S

The unit used in config.g is different from the unit used in the tool.
For maximum speed(M203) and Jerk(M566) the unit is mm/min in the config.g file, but mm/s for the tool. You need to divide the values for M203 and M566 by 60. If you still have problems, you can upload your gcode so I can take a look. -
Makes sense, I will check and let you know
Thanks!
