So I noticed that when I first start my printer up and run my extruder it goes unreasonably fast. I looked in the config file and here are the settings for the extruder:
Extruder module configuration
extruder_module_enable true # Whether to activate the extruder module at all. All configuration is ignored if false
extruder_steps_per_mm 174.87 # Steps per mm for extruder stepper
extruder_default_feed_rate 400 # Default rate ( mm/minute ) for moves where only the extruder moves
extruder_acceleration 3000 # Acceleration in mm/sec^2 only used for retracts
extruder_max_speed 100 # mm/sec NOTE only used for retracts
I have tried changing the numbers for default feed rate and max speed but it doesn’t seem to make any difference when I try running the extruder. Has anyone else had a similar problem? and any suggestions for things to try?
The software we are using is matter control (hopefully that answers your question) and they do have a extruder speed but it doesn’t seem to make a difference. I have just been using the G code terminal to pass a g code that sets the feed rate for the extruder.
extruder_default_feed_rate is not currently a valid config option, the default_feed_rate is used in the old config system, the new config syntax would be…
extruder.hotend.default_feed_rate
to set the default feedrate for an extruder. and does in fact seem to be missing. However note that the extruder default feedrate will only ever be used directly after a reset and if no Fxxx parameter has been used.
I recommend you update you config to the new config syntax for extruders as the old config will soon be deprecated.
I have the same problem after first start.
With Octoprint I send:
G91
G1 E5 F10
And the extruder is much too fast. Usually I need it to change the filament.
I switched between different edge branches. And on all it is the same.
Then I switched to the master branch and there it is working. I am able to set the extruder feed rate.
I did some more tests.
It is not only a issue after first start. Even after a print or after a movement of the axis with extruding.
During one of the axis is moving the F parameter is working like it has to. Something like G1 E5 X100 F100.
But without a movment of one of the axis x, y or z the F parameter is ignored by the smoothie.
There is no difference in the moving speed of the extruder between for example G1 E5 F10 or G1 E5 F100.
The extruder is always turning too fast.
We talked with some more people and I guess that it is actually a bug in smoothieware’s software and hopefully they are working on it so the default speed command will start working.
I think the same.
I had using Marlin and Repetier before on Ramps.
And there was it working like expected.
Even if you switch to the master branch of smoothie it ist working too.
But not on edge.
