So I have received my other printer and I have been greatly impressed with the quality and the ability to print right after I assembled it. I had one problem and it was with bearing that were too tight. Once I fixed that I have been printing nonstop with no errors. The following are printed using Cura slicer with the default setting and the other slicer software with the basic setting. The Silver is the other PLA while the purple is the MakerTech PLA.
Thank you
Also it seems like I will have some spare parts and if any has a "quality" idea for them besides stick them.......... I would like to see and or hear it.
Thank you for the forums.
Very tiny adjustments of the two eccentric guides for the X-axis build plate was my issue. Agree, at either extreme of the build base it is tight and does vibrate if too tight. The build base for mine is very slightly bent on the far right side, I (as carefully as I could) tried straightening/bending it out and did get a little better.
Trick for me, was to adjust those guides just the tiny, tiny, tiniest little turn each separately and watch with a bright light directly above the plate, with a a straight edge (white paper worked well for me) and watch the shadow while moving X-axis 10-100mm each direction, to see if it moved side to side - I think I posted a video of what was happening somewhere in the forums.
At first it would definitely shift .5-2mm as it would change from left to right direction... move +10, then move -10 observe the shift... slightly move first eccentric, repeat with second eccentric.
While I had things working well, I changed out the couple and the lead-screw nut on my Z-Axis and I can no longer get Z-wobble under control. I shouldn't have touched it, since then - I've tried going back to exactly what I had and multiple other iterations and I cannot get rid of the 8mm Z-axis wobble showing up. I THINK I got really lucky just putting the lead-screw nut in the hole of the gantry when everything was working great - and now I can't get it back in the right spot of something. Grrrr. I have some new nuts to try - brass are bad, and the plastic ones seem to vary greatly...
Should have left it alone once I got everything tuned. Except for that 8mm wobble though, everything else still works great on the unit. Good first layers (putting spacers in between the build plate and base plate helped a LOT here, especially in the middle around 150mm mark. Is tight enough in there that I didn't need screws/glue. That got the build surface straighter instead of warping up from the center to all the corners. I'll post about that at some point, just too busy.
Could u point out which bearing was too tight and what was the symptoms of that?
I cannot get rid of the X wobble... if i adjust the exentric guides so there is no wobble in the plate then at the extremums it wont run smootly and starts to "jitter"... when i adjust the exentrics during the printing i get smooth sailin but i can see how the plate wobbles at extremums and i cannot find the sweetspot where they both are minimum :(
So... what was the question around "Reason to stay with Axis?" about? Personally... we also have a factory assembled Prusa i3 MK3S that my wife primarily uses, and we have a Prusa Mini that just arrived and we'll be setting up this weekend - light assembly needed. Also have one of the JD Maker Artist D Independent Dual Extruder Pro's from Kickstarter, that hopefully ships in January and isn't a massive hoax. : -)
That said, the Axis is still getting used, and my reason is that I've learned a ton about 3D printing with it, and still have fun continuing to see how much better I can make it with each thing I read or learn. That's my reason.
