Wizard extrudes much less than 100mm during test extrusion #7
Comments
Seconded; Except mine extrudes none. PrintRun extrudes fine. Win7 64, JRE32, pypy included in package ...I'm not smart enough to get Alpha4 working yet... |
@frollard Have you made sure that PrintRun is not already connected to your Ultimaker when you make the test extrusion? There must be no active connection to your Ultimaker when you click the button for the test extrusion. |
Correct, only skeinpypy running... |
The problem is in the test extrusion. It completely ignores the given "steps per E" setting. The released version also has the problem that it closes the connection to the printer before the extrusion is done, which can cause the extrusion to stop. Both problems should be fixed now, but I'll have a good test with them before I close this. |
Sounds wonderful! sub-section of the problem - now if the test works, that is great, but does the rest of the skeining use the number from the tests? I found even if I changed the number manually, the output gcode still wouldn't allow the extruder to run remotely fast enough to print (about 10-20% of the required speed), regardless of the steps value. |
Check the resulting GCode, there should be an M92 Exxx in the final gcode, right at the top. The number should also have been saved in the preferences.ini file. |
Current (same as I was using before) version has no M92 values anywhere in the gcode file. Forgive my extreme ignorance; I'm new to github and python - which files should I replace to get the newest version? ;TYPE:CUSTOM |
You should replace all files in the SkeinPyPy folder. But the file that is causing this is SkeinPyPy/fabmetheus_utilities/settings.py |
BAM. ;TYPE:CUSTOM I was 'save link as' on the files and of course that links to the page describing the changes; once I pulled the zip file and used that everything is glorious! Now I just need a 'reasonable hour' to go to the shop where the maker is and see if it will print! This took skeining a sphere from 6 minutes to 35 seconds! You (and other collaborators) are truly heroes! |
So, to further the ORIGINAL issue; the bot prints correctly with the number 890ish...BUT, that still only 'test' extrudes 25mm. To get it up to the correct length it wants a number 3000-6000, which gives a full 100mm, but then when printing it goes ape-poop and tries to extrude way faster than usual! The wizard still needs some tweaking; --900 extrudes about 25mm at a SLOW speed |
Odd. I ask for an extrusion at 300mm/s, which should be quite fast. The wizard does: |
Good call; max it could do in that time was 50mm... To be as clear as possible, there was a definitive SPEED difference too when I used it, it extruded for about 3-5 seconds each time. When I up the number it extrudes for the same amount of time but it just comes out faster. |
I tested this before the Beta4 release, and now it worked flawlessly for me. |
On my machine the first run wizard extrudes more like 25mm of filament instead of 100mm (measured by removing the bowden cable from the extruder and starting the filament level with the top of the extruder, extruding the filament, and then measuring from the top of the extruded filament down to the top of the extruder).
Using PrintRun to extrude 100mm of filament works fine.
I'm using my branch, which should be equivalent to your branch at this point in time.
