Hmm… Does your CTC have a usb dongle which you need to buy print time with? There’s some CTCs out there with that and they’re totally locked down, you can’t change the firmware on them.

It didn’t come with anything like that as far as I can see.
I’ll see what I can do, I have some time to try some more now. I usually have my brother to hand though to help with the button pushing.
We were trying for 2 or 3 hours yesterday with no progress.
I have been trying for another hour or so and still no dice. On the verge of giving up, I have no idea how it can be a timing problem any more, I have tried every which way possible.
Hi there,
Sorry to hear that things aren’t going that well for you. If we are to presume that it is hardly a timing issue by now, then it could still be possible that you’d be experiencing the same troubles I did in the beginning, in spite of me using linux - meaning, it could be that ReplicatorG isn’t actually communicating properly with your printer at all.
In my case, as stated below, while running Replicatorg-0040r33-Sailfish-linux.tgz from the command line, I would get the /dev/ttyACM0 device discovered but when pressing Upload for the firmware part, I got an error specific to linux claiming that lib-usb 0.4.1 could not be found. Without this library working, it made total sense to me to first fix that and then deal with timings.
My point is, if by some reason your system has an issue with the USB communication somehow specific to the printer and along the lines of what happened with me, that might be it.
Unfortunately I don’t have any other alternative besides suggesting you’d get an Ubuntu 14.04.3 LTS like I have and use it to replicate my steps. At least by that point and running ReplicatorG off of the command line, we might get some hints as to what is happening, either bad timing or USB communication all the way.
If no other solution is presented, I’d be willing to guide you with this if you decide to do it - you can reach me directly through my Hub and we’d take it from there.
Are you able to post the terminal output as you do the upload/reset routine?
Hi, it seems that all is ok in terms of USB there, so if you rule out the reset button pressing, I think we’ve hit a dead end with this one, unless anyone else has any suggestions. 
Thank you for all the help, it was much appreciated, its a shame in the end it didn’t turn out well. I think I will try and get a replacement printer and see if another does the job. If not, then I don’t have a clue…
