A3S V1 - Must Tighten Screw for Leveling Position 1 to the Maximum Amount, and Z Degreasing
I have community firmware for board and for LCD.
Problems I can solve myself (probably)
1. I plan to tune the drivers, but print quality is usually excellent after using the "baby-" feature of the community board firmware and LCD firmware. I got the printer from eBay AS-IS, and after a long time I realized that the z stop connector was not connected. It may have been pulled out due to all of the cables being loose inside, but I'm not sure why they were loose. The printer was returned to a store. I re-routed the wires and fastened the wire tie-downs. I plan to get improved wiring to the stepper motor and add a drag chain, with PTFE tube to make it move better as recommended--If you know the length of drag chain to get such as on Amazon, let me know (I asked JGAURORA tech support just now). I plan to eliminate the need for babying by using mesh leveling. If you have any concerns about the above, let me know. I hope I haven't damaged or pushed my z stop sensor downward by jamming it so many times!
2. I assume the better bearings (linked from https://jgaurorawiki.com/essentials) work on my version of the A3S, so I plan to replace the stock bearings.
The problems that remain:
3. For the rear left (position 1 for leveling), I have to tighten the screw all the way down--the other 3 seem to level fine. The bed is slightly bowed upward in the middle, but I suppose I can tighten the other 3 then use mesh leveling to compensate for that purposeful extra tweak downward. However, I cannot get the rear left one any lower. It is tightened as much as I possibly can tighten it just to make paper fit between it and the bed. The bed assembly is seated in the gantry as tightly as possible. Are there any concerns, or should I just leave it and do the above (make others extra low then use mesh leveling)? Should I get a shorter spring and live with it?
4. As I said, I plan to tune the drivers. After running the z up and down many times, it started moving smoothly, but I'll replace the gummy grease (it stutters occasionally, and on jogging only if moving in 10mm increments--it seemed to start after changing to community firmware). I have wax&grease remover but it will be really messy using brushes or paper towels in place (I don't plan to disassemble)--I can try rags or old socks. If you have any tips for removing the stock grease let me know.
