In order to move my spools further from the printer, and to also solve feed issues to the tool head, I am working on designing a simple buffer that can separate feeding the printer vs feeding the toolhead. I have found there is just too much resistance for the toolhead to handle it on its own. it messes with everything from flow and TAP readings.

The design is to keep the buffer full, and use a contact switch to read once it is full. When the switch releases, run the second extruder to feed into the buffer again.

I took apart my extruder today to see how its going, and it not going well.

So it looks like a bearing was missing on the idler axle here, and it caused some uneven torsion that ended up cutting a notch into it. I ordered up some replacement parts, and found that the original parts I got were really sub par. The new hardware has much better teeth on the filament contact. We’ll see how things go.

I was playing around with vase mode and some simple threads. Came up a nice cheap coin tube.

To get rid of more slop in z homing, I’m going to try the CNC tap.
