Page 132, of Assembly Manual is wrong.

Hello,
Okay, I've been kept out of the shop for a few weeks due to excessive heat. But, I followed the instructions but, went by the pictures. The 18 gauge wire, is the one axis that has only four wires in it, and the picture shows the 18 gauge wire going to the stepping motor. It doesn't that much current. I was working on quick disconnects, and shortening up wire and repinning plugs to the motors. Most of the motors have way more wire than they need on them, and I'm just shoring things up. Then I realized, the picture was wrong. I've got 8 wires, that include the wires for the stepping motor at 22 AWG. Four 22 AWG, and four Peek and Layer fan wires. Those four are by written instruction by gauge to be used for the filament/ezstruder. But, in the images, it's wrong. First, I trimmed it to place the stepping ezstruder motor, then I realized, I was following the pictures, and this was probably why somebody else was complaining about their hot end not heating up. The wire couldn't carry enough current and was probably getting hot trying to heat up the hot end with wire that couldn't carry enough current. I'm just happy that I went to the extra trouble to cable lacing, trimming down my cable lengths to avoid the resistance of the longer wire, and basically replacing my male and female plugs after measuring and shortening the wires.
This room, almost gets as hot as the inside of car, and that has been fixed.
I think that the main overwhelming problem with the Assembly Manual, is the little details you miss. I've missed it for this long. But, every image of a melamine part, needs to include Top in the view, or bottom, so that the pieces are all turned the same way. I can see that there's a top down, middle up kind of layout of the instructions. When you look at an image, you want them to be aligned with holding the page right side up, and looking at the front of the machine. But, it's not just front to back, the top is the top, even if all you'd see is the bottom of a piece of melamine.
The picture, and wire gauge, and even axis is wrong in the image for the motor you're going to wire. If they follow this picture, the gauge of wire they'll be using is too small to carry enough current to the hot end.

On page 143, in your revised manual. I assumed that bottom of the triangle was the front of the machine but, I put that in upside down. I do that with the next piece of melamine, and it fixes itself by being a mirror image. I can reach the ezstruder from the left hand side from the front of the machine that way. It works being left handed like I am.
