MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Does anybody has this stuttering movements when printing small curved or round objects?
I just upgraded from stock firmware to Marlin 1.10 RC8 with "ensure smooth movement" option enabled.
And prints look much better now.https://imageshack.com/i/plAdeJITj
Left is the new firmware, right the geeetech original firmware.
Both prints used the same gcode file with 65 mm/s.
For me the work to configure the new version was worth it.
Looks like a substantial difference.. How much work is there to configure the firmware as you've done?
hmm, how much work / time is it?
I think I spent a couple of hours, at least 6 or 8.
Because it's my first firmware upgrade to a newer version.
I started readinghttp://marlinfw.org/docs/configuration/configuration.html
to understand what does each parameter do.
Then I tried to compare configuration.h and configuration_adv.h from the RC build with the original Geeetech ones using WinMerge.
But Geeetech moved some Parameters to a differnent place (maybe for easier Setup).
That made it hard to compare the file with this tool.
Then I searched the Parameters from the original Firmware in the new RC build to find out where are different values set and decided what will be the values in the new Firmware.
At the end I stepped through the new Firmware (configuration.h and configuration_adv.h) like described inhttp://marlinfw.org/docs/configuration/configuration.html
to figure out what to with the new Features.
Some parameters were renamed in the new RC, in the old Firmware were some erros which don't have any effect in the old Firmware but in the new Firmware (Geeetech declared 2 different LCD Displays, ...).
You have to use a newer version of arduino IDE (at least 1.6.8) for compiling and uploading the new firmware build.
I did not check the auto leveling Feature yet, because my printer is good calibrated at the moment.
Marlin 1.10 RC8 has a bit different handling for auto leveling.http://marlinfw.org/meta/features/
I plan to try the new linear advanced Extrusion algorythm in the future.
It's a good experience and I learned a lot about what the printer does.
