I was updating from an original SD2 to the new Marlin FW and was a few steps away from pulling my hair out. The Baud rate thing I figured might be somewhere in the instructions.

250000 is the default baud rate the SD is supposed  to run at.. I guess I should have looked at your previous posts... I see you mention you set it at 115K... oh well smile

Yea, my bad.  Somehow my firmware had 115200 set, and I needed them to be in sync.  I've updated the firmware and am on board with 250000, pun intended.

Thanks for setting me straight.

I decided to try other things than the driver.  I re-flashed the SD firmware: no improvement.

In idle desperation, I decided to try all the baud rate options.  At a baud rate of 250000, communication was established!  I don't know why that baud rate, but since it works, I'm using it!

Of course, because I re-flashed the SD firmware I have to recalibrate everything.  That is made worse because some of the settings in the RH files, as downloaded from SD's website, are wildly off.  For Christ's sake, the filament diameter was set to 3mm!!  But, at least it's working again!!

Thanks to everyone for helping!

That technique shouldn't be required.  Fortunately I will go home again in several weeks and my regular computer should still function ok.

Before this this thread dies, I would like to thank all that have tried to help.

I'm not talking nanosecond, but I'm saying within a second of hitting reset. I keep one hand on the mouse to click repetier connect, one on my sanguinololu reset button (gray button on the controller).

I need to do this for my setup, but the thing is that the error I have when I don't do this is just that repetier has 7 commands waiting forever.

And, have you tried uninstalling and reinstalling repetier?

Oh, well, there are a good amount of ways to incorrectly install the drivers. Recently windows has been trying to autoinstall arduino drivers, which is new in the last two months for them to do so, but it never does it correctly.

What is the port that is "correctly" working called? Is it called Serial USB comm or just USB comm port?  The first is I believe what it should be.

Can you uninstall them? Then reinstall by choosing to install files from a local location, and "have disk" and then direct it to the folder in arduino with the .inf files.


I've installed from local location, as administrator, from administrator account.  I've run the installer from FTDIchip.com both by running it after download (run not save), downloaded, saved, and then run.  I've used the installer from SD.  I've tried both the new driver (Aug 1 2013) and the one dated July 2013.

I've tried a different USB cable.

In device manager, it shows as "USB Serial Port (Com6)" and it indicates all is working as it should.  In Devices and Printers is shows as a mouse.  That shouldn't be a problem as I've run other FTDI adapters OK that have been shown as mouse.

I'm completely stumped!

everything is listed as usb , you can't tell one from the other. that's why i HAVE to try all of them.
that's just how windows xp rolls, plus it was too slow to slice anything... so i stopped using it.

Me too!

I'm pretty sure the problem is with the driver installation.  I just can't think of any way to install it that I haven't tried.

I have installed the serial driver and RH per Solidoodle's web site.

you mean USB driver?
you might not be connecting to the correct port... when i switched from win7 to winXP, I have to try every single port until I got the correct port... there are about 20 ports from RH's port list.

For the record, you should go into device manager of windows. Under the "ports" section you can see a "serial usb" device, and that's your printer. Next time you won't need to try all of the ports smile

You can also look at what ports are available before you plug in the printer, and then look at what ports are available after you plug in the printer and refresh. The new one is the printer! smile
