Today I want to talk about something that can happen while printing, axis skips. Here's some of the most common reasons why you may see axis skips in your prints and how to address them:
There is nothing more frustrating than print failure from the binding that occurs when your filament get tangled. Nothing. It happened to me recently and I was so bummed because the print was coming along really well. I was being a little lax about my filament management with a brand new spool (the filament already seems like it wanted to jump off). Want to reduce the risk? Filament management is key to avoiding this type of mess. Being cognizant of how filament is stored, strapping down the loose end and stacking upright can also help keep tangles from even starting. Sometimes they are unavoidable, perhaps the roll was spooled poorly.
Filament age & quality
Not all filaments are the manufactured the same and it does degrade over time. For some tips, we have an article that addresses some of the issues regarding print quality due to filament.
Bed adhesion issues
Prints lifting or shifting. This happened to me recently too (I do a lot of printing) and made me less than happy. In my case the print was thin and narrow, it just didn't have enough base to stay on the bed. It just peeled off and was sliding around, but not before confusing me for a minute. Sometimes there's enough lift in the print that the extruder will just bounce off of or drag over causing an axis skip, jump and hop. We have some suggestions to help avoid this by making your prints stay put.
Print speeds are too fast. If you are printing something at full speeds on too intricate a pathway you're going to see skipping. Slowing down the rate at which you are printing can help you prevent this. In fact, if you want to know more on making adjustments to your print settings, we have a full article on adjusting Cura settings. But you can also adjust the speed in Octoprint manually using the terminal interface by using the M220 S___ command during printing. The number that "S" represents is a percentage of the full speed. So M220 S100 is 100% speed according to the generated gcode file. While M220 S50 is 50% speed, cutting the travel time down by half.
Okay, that's it for today. :-)
