Of course I realize no one is reading any of this stuff and I'm just talking to myself. That said, I need to keep a record so why not.
Been busy with lots of personal stuff for a long time now and finally I realize I need to put some mental energy towards things I want to actually work on. So I cleaned up my office and resurrected my 3D printer. I found out ( I think ) why my Y-axis was shifting all over the place when I last stopped using it.
The motor for the Y axis has a gear on it that was split by the torque of one of the screws keeping it clamped to the motor post. The more I tightened the post on one side the more it pushed the other one away - resulting in pretty much a constant weak tension. I took away one of the screws so the single screw would force the entire post to be used as a backing - which allowed it to be clamped more - resulting in no more slipping.
I also struggled with the extruder as it wouldn't suck in the purple PLA like it should. Took the extruder apart and found an old piece of orange sticking out of the top - I think the new purple was unable to get enough force directly on the old orange to push it through and enter the channel itself. I removed the old orange after heating it up outside of the chassis then put it all back together.
Was able to heat the bed up to 60deg celcius (that seems strangely hot to me). I do remember trying to use PLA but having trouble heating the bed up to a high enough temp.
I ran a test of the hollow box and got the best results I had ever received in the past. Even the bridging at the top was improved.
The whole point of this exercise was getting the printer operational so I can use it on the ITC project. It had been my goal to print out a new gun design better molded to my needs. This is a good start.
