So, I dont have a photo for this. but hear me out because I swear this is a THING. So I've been getting random print quality at times. And this often noticible ticking noise from my z-axis, as though its stuck between layers. Looking over it.. if the z-steps per mm is 1600, or 0.000625mm per step. Then when doing the math, it seems like i should be able to print at .2mm perfectly right? But it seems iffy how it starts outputting filament. And I was wondering if theres a connection between this ticking in my z axis, and what feels like over compressed layers. Is there something that comes to mind to help diagnose this? I get some realy poor prints, and then realy good prints at seemingly random intervals.
Yeah I was starting to put 3 in 1 oil on them to see if that would help last night. Also forcing the bed down by hand after the first few layers. Im thinking since the z is not under a constant downforce from a pair of springs, the grease I had in there may have caked up and prevented it from settling between layer prints? Set the voltage back when I built it, should be ok, Gonna try cleaning off as much lithium grease there is, put more 3-in1- on it, and then tram it up and down a bunch to get it worked out a bit. Has anyone made upgrades that use any kind of constant spring force to push the axis down into place? I remember my Taz 2 had that in a way.
If your guide rods are reasonably straight, the linear bearings decent, and you've trammed the system, gravity is all you should need.
Cleaning up the grease and tramming it up and down a bit using oil seems to have helped clean it up. Now looking at constant texturing on the ouside. some ringing, some elephant footing..
Elephant footing is purely about the height of your first layer. If you push the bed closer to the nozzle than the layer height, the foot will appear.
Yeah I've managed to change the layer offset height. Little bit of footing but its much much better. Printed a test cube in vase mode at .05mm, complete success!
