mferrand,
I assume you've done all of this:
1. Go to the MakerGear website, to the Instructions tab and select the "M2 Assembled" item. (Opens this page:
http://www.makergear.com/pages/m2-assembled )
2. Scroll down to the Windows Driver item, click the word "Driver", which downloads the file
http://cdn.shopify.com/s/files/1/0030/7 ... er.zip?920 (RAMBo_USBdriver.zip).
3. Went to the folder where that file was downloaded and opened it and extracted / copied out the two files:
* Rambo.CAT
* Rambo.INF
4. Plugged the cable from the M2 (with NO intervening USB hub) directly into your PC. THIS IS IMPORTANT. Many people have reported that they cannot talk to their M2 through a USB hub (for whatever reason...??? ).
5. Directed Windows to the folder containing the INF and CAT files extracted above.
6. Let Vista do its thing, resulting in a COM port showing up in your list of ports (often seems to show up as COM3).
7. Opened up S3D and its Machine Control Panel (MCP), then hit the "Refresh" button to refresh the list of ports.
8. Checked the baud rate. (Try both the highest ones: 115,200 and the 230k or whatever it is. I forget which of them works... not at my printer and not using my printing notebook right now...)
9. Selected the new port and clicked "Connect".
10. Tried this with every COM port and baud rate combination, just to be sure.
11. e-mailed S3D tech support for assistance. (Actually, this should be #1...)
As a last resort, install Linux (Ubuntu, Mint, Zorin, whatever) ---- no driver required. (Not in a virtual machine --- S3D checks for this and the license won't work in a VM...)
