So, this morning.. I had a problem when my Eris suddenly started to air-print. As soon as I noticed, I quickly cancelled the print and then tried unloading the filament using the provided gcode macro. But then, I noticed that the filament was slipping, and was not getting pulled back properly.
After a close observation, I diagnosed the problem to be a loose hobbled bolt. Sometimes it was spinning around the shaft, hence the filament was not getting pulled or pushed properly.
I then removed the clear front-cover, turned the hobbled-bolt to make sure that the set-screw was right above the flat-part of the shaft, removed the screw, put some blue loctite, and screwed it back in. The bolt and bearing alignment appeared to look OK. Then waited for about 10mins, for the loctite to set, and loaded the filament, and it's all good now. Hope it stays that way.
Also, I have been noticing some squeaking, when the carriages move up and down, and at the ball-joints as well. So, got some PTFE silicone grease from a Tamiya kit, and carefully applied a (very) little bit on each of the 12 ball-joints and the 6 vertical rods. Sounds a lot better, and smoother now.
Finally, the fan-shroud housing the LED (facing towards the front of the Eris) had developed a small gap, with the top black part. Since, the part-cooling effectiveness is already quite low, this small gap was leaking some of the air, meant to cool the printed part. I tried to press them together, but there was still a gap. The bottom and top black parts on the other sides are flush, with no gap. So, I cut a small piece of PVC Electrical Tape (Black) and sealed that gap. Since, nothing should get hot here, I guess I'm good.
Anyone else have had the above issue with the EZ-Struder, and the other two problems I've noticed? Perhaps you've had more creative solutions than I could come up with.
Meanwhile, this unit is exactly one week old, and has a total print time of about 35hours.
