New RepRapFirmware release 1.00k for Duet electronics February 22, 2015 02:21PM |
I've released RepRapFirmware 1.00k-dc42 at [github.com]. The major new features in this release are:
1. When a print is paused, you can use a G1 command with the R1 parameter to make the head go back to the pause location, optionally with XYZ offsets. The main application of this is in the resume macro file, to allow you to reverse a filament retraction after moving the head back. For example:
File pause.g:
File resume.g:
2. The calculation of the estimated time to completion of the print, which was previously done in the web interface, is now done by the firmware. This means that it is not only available to the web interface, but is also available to (and displayed by) PanelDue.
The three estimates are based on the proportion of the file processed, the proportion of the total filament consumed, and the proportion of the object height completed. The filament-based estimate is usually the most accurate, and the height-based estimate the least accurate (because it depends so much on the shape of the object).
3. The number of moves buffered is varied dynamically, depending on how long the already-queues moves will take. This means that changes to the speed factor and extrusion factors take effect much more quickly than they sometimes used to, for example when printing infill for a large object.

File pause.g:
G91 ; relative mode G1 Z3 E-5 F200 ; move head up 3mm and retract 5mm of filament G90 ; absolute mode G1 X-5 Y0 F5000 ; move head to park position M106 S0 ; fan off
File resume.g:
G1 R1 Z3 F5000 ; move head to 3mm above paused position G1 R1 E5 F200 ; move head down to paused position and reverse the retraction
