Ensure all bearings are rolling on cheapskate!

I know it seems obvious but My last few prints had really poor quality even after re-calibrating like 10 times. I was under the assumption that it had something to do with my new dual hot-end setup but it reality it wasn't. The top cam bearing on my x-axis came a little loose (as they tend to do after time). I ended up snugging it up during a print and the difference is honestly night and day.... So when your prints start looking like the sand at low tide do yourself a favor and check your bearings

Nice job, and great reminder!

Now, get that warping under control!!!

I still have to assemble mine the rest of the way, but here is what I found out.

My eccentric spacers on the right side of my rails were not all touching. Loosening the tension roller (the outside of the rail) and then adjusting the eccentric spacers (right side of the rail) so that it did not let me twist the back of the arm mount resulted in it not having an twist when grabbing the side of the arm mount. I then tightened the tension roller (outside of the printer with the screws on the inside of the printer) until it was tight, but even and then loosened them up some until there was no friction and I could flick the arm mount up with my finger and it would easily fall back down. You have to be careful to get the right and left screw for the tension roller tightened equally though or there will be problems. Essentially, tighten the screws on the sides of the rail before you tighten the screws that face the inside of the printer and make sure each set of screws are tightened equally and you should be fine.

I hope to see the arms and bearings in real action by Saturday.
