Hmm, that's going to make it tricky, then. The Melzi uses an FTDi chip for USB to serial. No idea if it has flow control. Looks like a specific version of Pronterface for Ormerod will be needed.

This firmware with the Pronterface fix is working great for me.
Does this binary also include your previous Network Fixes ?, My Network connection with this seems to have gone back to the
works sometimes stage with lots of Network connection error code -10.

Having said that the improvement in USB speed is great, SD upload over USB is about 12 times faster
With the various mechanical electrical and software issues it did seem at one point that the Ormerod was going
to have been a bit of a lemon, but having now got most of the mechanical issues patched/sorted and the firmware
starting to come together it's actually looking quite good.
Printed my first 2 'useful' parts today (Servo mounts for a CNC mill) this was about my 9000th attempt (only slight exageration)
they are fairly large (185mm * 90mm * 20mm) and the gcode is just over 3 gig. So attempts so far had suffered from almost all
of the issues (fan cooling, X runnoer bearing, head droop, z runner wobble and it took about 15 mins each time to upload gcode)
With a new fan cover, new Z runner, new hot end mount block, new fan (orig one seized for some reason!!), new 12 volt PSU (not an ATX)
and this firmware upload of code was less than 1 min, printing went well, took 5 hours but I have the speeds set rather conservatively
and the part came out great :-)
At last it feels like the Ormerod may become a useful tool.
Still some work, I think I will be making an aluminium bed and need to do something about the X axis (the taped on hacksaw blade is
a bit too much of a bodge to last) but closer :-)

Hopefully you've taken some load off RRP for them to focus on other improvements

Haha, I've been sitting on a beach in the Caribbean, counting piles of money, drinking Mojitos, while being fanned by dusky maidens, while dc42 does all the work, all this time!

* "Hardware" (mechanical build/ Duet board) developments/ revisions since the first build (like a release history)
* same for Software (yes I know it's @ github but you have to skim through the history)
* Improvement pool with suggestions from RRP/ community regarding hardware/ software
* Sticky FAQ (mechanical build, hardware, software)

@ dc I thought I'd uploaded the pic before I came home - I've added it now to the 60micron thread - the surface finish to the eye is somewhere between fine silk and satin, and I'm ery pleased

On the pausing issue, I've never had satisfactory recovery from pausing (not tried it much), and it's always been delayed - the main problem on trying to resume a paused print for me (which may be a repetier issue) is that extrusion becomes flaky, retraction works fine, but extrusion just jitters, so I won't miss that! if I need to do an emergency stop I cut power on the atx, which is 100% reliable and instant, though I then have to start from scratch... maybe a hardware interrupt (Markus implied he's working on a control panel earlier - a button for pause would be good) could be a more general (and host-independent) solution?, though I guess the firmware would have to store a big buffer of commands if it didn't tell the host it was stalled...
