Is this a good sign or bad sign? Problems talking to machine I knew this is where i'd start to struggle! I can assemble bits of metal but making a computer talk to it would always be a challenge! Story so far: * 2 different Macs, 1 PC running Vista. Using Vista as stuggled to find others talking about Mac issues. * Battled with drivers for USB TTL and getting software to recognise COM port but I think I have sorted that. * Several installs and uninstalls of Java including v5 & 6 * Have a few lights flashing on the USB TTL cable and the motherboard which is more than i had a few days back. But now a cry for help please!! I'm looking for confirmation that the PC is talking to the machine. I cannot achieve this myself as all I can do is try to jog the axes using the reprap software but nowt happens. Does the stuff below show any promise?!

Sounds like we are at similar point in our RepRap development!

Just to close out my experience of this, it is exactly the same as yours .... software incompatiblity. It is a minefield and not for the feint hearted or none techies like me!

So much so, that I have spent 2 WHOLE DAYS trying to flash the software .... using 3 different computers!

One thing RepRap teaches ....... is patience!

Enjoy

PS my advice to any potential RepRap'rs of tomorrow, either have oodles or patience or a degree in Computing!]]> mattuwattu RepRap Host Mon, 25 Apr 2011 17:53:03 -0400 https://reprap.org/forum/read.php?12,64777,72406#msg-72406 Re: Is this a good sign or bad sign?

A) I now know how to flash the software
B) The bug has disappeared so I confirm it was the cause of the problem]]> Matthieu RepRap Host Wed, 02 Feb 2011 17:00:00 -0500 https://reprap.org/forum/read.php?12,64777,72401#msg-72401 Re: Is this a good sign or bad sign?

I have the same issue here with the following twist, which kinda confirm Traumflug idea (and kinda not).

Last month I was able to have my reprap move and extrude kinda properly, with an about-6-months-old firmware and software, except that I was not able to extrude at a correct speed. So, I went on looking at the preference options, which were not up to date with the wiki.

So I downloaded the latest host software, made a few tests last week without solving my issues, but at least the reprap was still moving, extruding etc.

Today without further changes in the software I get the same error message as mattuwattu and the reprap is not moving.

So yes, changing the host software was probably a cause of the issue, yet I don't understand why the new software was working last week and not today.

And now I need to learn how to flash the firmware...]]> Matthieu RepRap Host Wed, 02 Feb 2011 16:04:40 -0500 https://reprap.org/forum/read.php?12,64777,64807#msg-64807 Re: Is this a good sign or bad sign?
