Making headway.
Added 2019-04-26 14:37:41 +0000 UTCCustom prusa is of course exhibiting the same issues a regular prusa has which is some minor uneven extrusion but using the 0.9 degree motors on the x and y have completely eliminated vertical banding as it should. π€
Switching to geared extruders like the BMG sure do help this. As my research continues on this I've found that duet had a long conversation about how prusa implemented Linearity correction to help with this.
In the end the conversation turned into one of pure direct drive vs geared where geared eliminated this issue by further reducing inconsistencies caused by the way trinamics drivers interpolate movement.
Basically they too found that gearing from a BMG or Titan reduced this issue and was common to printers using direct drive and trinamics drivers.
I built the custom Bear using a stock Bear extruder which is why I'm seeing test good print quality but still seeing the small issue with Linearity. I could attempt to tune this in Marlin but then it's not universal.
So do I switch to the Bondtech extruder? Do I try something else????
I do have one more bondtech extruder I could put on this and I also have other crazy gadgets I could try so why not. I'm going to finish up my last test print here and try using the bondtech extruder I have but will cut my microstepping to 1/16 from 1/32 so it's running at 415 microsteps. It will completely eliminate the 602 and make it print super pretty.
