Page 132, of Assembly Manual is wrong.

[Flavored Coffee]

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.

Put the shotgun down, @geneb, I'm sure he means well.

geneb I would just like to thank you for such a wonderful manual. I printed out three, one for quick reference, one to sit next to the "thinker" in the bathroom and one for my son. My nine year old son has been shlepping the 279 page monster to school so he can read it at recess. Not sure if you got paid to write it, but it was one of the leading reasons I chose to purchase a R Max 2. Thank you for making it fun to read and not just another set of "stereo instructions".

You're quite welcome! I'm glad you like it.

It's up to 280 pages now. I posted an update over the weekend.

Geneb, I will say thanks also for doing the updates, I have seen plenty of manuals that are never updated and that can make life very difficult when dealing with a technical item, so thanks!!

You're quite welcome!

Updating frequently can be a double-edged sword. People would start building the machine based on a manual revision they downloaded when they ordered, only to get caught by a correction or clarification in an update that happened the day before their kit arrived.

I try to keep the manual revision post updated with the current upload date & revision number.

I just finished my build. I was rather impressed by the part checklists, confused by the tiny electrical diagrams, and mystified by the complete lack of instructions.

I was thrilled to find them online, but felt that Rostock should have enclosed a sheet of paper with a web address to the files at a minimum. The system comes with an SD card, the electronic file could have easily been installed on there before shipment. Also, how about some ABS? Just enough to print the parts in the book. I purchased my printer from Matter Hackers, they suggested I buy a roll of filament and suggested PLA or ABS. PLA seems easier so I purchased that, only to find out I needed ABS before I could even think or printing PLA.

Obviously this isn't a complaint at Geneb. The only things I would suggest are:
1. Add the list of optional items as part of the standard list and just mark them as "(optional)"
2. When I got to the electronics section, it wasn't clear that the section i had to wade through the current section and that electronics specific to my machine would come later.
3. When the printer build is done, before boot up, a note telling me that the two smaller fans were to be installed later would have been good.

Nothing big, just little suggestions to help other noobs not make the same mistakes I did.

Thanks again Geneb... couldn't have gotten this done without you!

Another thanks from me to Geneb for helping me get my machine built!

You're welcome! (all of you! )
