Long story short, I created a bunch of parts to make the entire moving end of the printer very rigid to help with small detailed prints.
Sort of a long write up so I did it in PDF format. Browser kept losing my drafts

The issue with having a bearing on the inside is that when you print at the base of the tower, the arms will hit the bearing. The arms will be 90º straight down at that point, which means everything under that pivot point needs to clear the moving arms.TwoTone wrote:Just curious after seeing this and some other custom carriers(Skates)
Since the weight is pulling inward, wouldn't it make more sense to have the bearings on the rear and front of the towers vs. the sides?
So the inside bearing could be above the arm and the other two would be in the rearHobby Creek wrote:The issue with having a bearing on the inside is that when you print at the base of the tower, the arms will hit the bearing.

I was originally just going to switch to carbon arms, then one thing led to the next and before you know it, I tore the whole printer apartDeltaCon wrote:Nice write-up. It all looks so simple when you see this, but I am always very hesitant to make such large mods myself. For me a safer route is through the well known SeeMe or TrickLaser upgrades. But this really looks RTM!
I did just what you said TwoTone. Works very nicely. http://forum.seemecnc.com/viewtopic.php ... 740#p95089TwoTone wrote:Just curious after seeing this and some other custom carriers(Skates)
