Hello, First of all, i have very very limited knowledge of programming/coding etc and i am unsure if this is the correct forum to ask this.

I am doing the part works www.3dprinter-collection.com.

I am up to a stage where i can print things out, however, i cannot get the printer to connect to my PC(Win10). It connects to my friends laptop(Win10) fine, but i can't rely on borrowing that all the time, and as the printer works while connected to the laptop, my conclusion is that my PC has a driver issue.

The printer uses the "Sangunio W/ ATmega1284p 16mhz"

Each time i plug it into my computer, windows says "USB Device not recognised" and under device manager it lists it under the name of "Unknown USB Device (Device Descriptor Request Failed)"

As far as i know, it is a driver problem because, as i said it works fine with a friends laptop.

so i was wondering and hoping that i could find some decent help in this forum, as Eaglemoss support "helpfully" suggested i uninstall the reinstall the printer software, which didn't work.

Nobody have any ideas?

Well, i had a look at the drivers on the laptop, copy and pasted all the driver files onto my computer but i think there is more to installing drivers than c/p some files.

I have no idea about 3D printers. I read up on it a little

 

http://reprap.org/wiki/Microcontroller_firmware_installation

 

https://www.safaribooksonline.com/library/view/3d-printing-with/9781782169888/apas02.html  <--- this link sounds like it would help you and says you can sign up for 10 days free, no idea if its legitimate or not

 

 

Did this thing come with a set of drivers? I would uninstall anything related to it on your PC then re install the drivers. Copy/paste doesn't work.

The good news is that you need no knowledge of coding or programming to install a printer, the bad news is that you do at least need to read the quick start guide !

 

First go to the manufacturer's web-site and download the latest drivers for your model of printer for Win 10 and save them to somewhere you can find them again. Then go into 'Control panel - Programs and features' and uninstall everything you can find relating to the printer and the printer drivers. There is no need to uninstall any of the software you use for generating designs.

 

Then go to the quick install guide. If you don't have a copy, download it from the manufacturer's site. Then check the installation sequence and follow it. I don't have any personal experience of 3D printers but there are two or three members in an electronics group I am a member of who do, but printers are notoriously fussy about the sequence in which they are connected and installed. As I have said elsewhere, it is one of few areas where I always read the manual first !

I built the thing, week by week, part by part, i've read every word in every issue, and followed every intstruction. Still get "Unknown USB Device (Device Descriptor Request Failed)"

It has just occurred to me. This post is #8 in this topic and you still haven't told us the make and model of this printer !

 

If you provide this information it is possible we can look at the manual ourselves and see if there is some little fact you have overlooked.

When a problem comes along... you must Wiki. Wiki-t it good!"

 

Can't connect to the Melzi (FTDI driver problem)

There has been an issue where a FTDI driver update, pushed out through Microsoft update, disables Melzi controllers that have a non-genuine FTDI chip. This chip is used for USB communication, so the board may look like it's working (LED flashing) but doesn't show up correctly, and Arduino IDE/Pronterface can't connect to it.

This thread describes the problem in detail: http://hackaday.com/2014/10/24/ftdi-screws-up-backs-down/

Diplomatti, you must try living up to your name and be more diplomatic. I asked for the make and model of this printer not the name of the magazine you are subscribing to, of which I was well aware. I am willing to google a known printer type to find its manual, I am not willing to buy a subscription to this magazine.

 

There is a considerable number of 3-D printers on the market ranging in price from £UK 100+ to £UK 100K+. which one is yours ?

Thank you for that. I have had a look at the manual for this printer and it seems that the USB port needs to be specified, p19 refers, and para 2 on p40. I assume you have a copy of the manual, but this is the URL in case you don't.

Can't specify ports when my computer doesn't recognize the printer. This is what happens https://youtu.be/YMR2gjKX0SI. I don't get near the stage to use the software.

Didn't the shopper where you bought the printer give you the video?
