Wow it was late last night and my post got mangled - I made the change to Teacup and didnt change Replicatorg at all... It seems easier to change teacup
See the edits above so you can actually read the post.... sorry everyone
I put a pull request to triffid_Hunter so hopefully it gets merged back into the main branch soon.

I found one thing that was creating issues for me in the stock replicatorg - whenever I printed or opened the control panel replicatorg locked up. it seems whenever replicatorg grabs a temperature reading it expects it in the form:
M105
ok
T:bla B:bla =this needs to be on its own line
Before Teacup would print out "ok T:bla B:bla" which replicatorg cannot parse (the parser is a little ha

So I got my machine working with Teacup (and only teacup)! It prints objects and no longer freezes! I am super happy
I put up some pics and descriptions here
The Knot was the first successful print I made. So far all my custom electronics and extruder are working wonderfully! Special thanks to Triffid_Hunter who helped me hunt down strange issues in the firmware.

So my wierd freezing problem has been narrowed down to the following:
When DDA_step sometimes fires it will write a value of zero to the timer
R Pos: 525,2606,1565,0,200,3,0 //last two are function calling settimer and value put into settimer
R Dst: 525,2663,1565,0,2300
So while it still needs to move in the Y direction - it instead calls setTimer(0) which turns off the next interrupt.

So I get an OK - and then the machine sends an Xoff command - and never sends Xon again - causing transmission to get frozen....
After this happens - the machine is frozen - and will not respond to commands again unless I reset
Edit: Looks like it is usually freezing after exiting a Z axis move to the next layer.
Edit2: Tried this with send.py on my linux box and shortly after it gets sent the

Hi - I have another problem which is proving difficult for me to debug. I made the test knot in repsnapper and exported gcode - however after building the second base layer my machine freezes. I am using realterm with Xon Xoff flow control compiled into the firmware. And it seems that after sending a bunch of commands in a row it causing the machine to freeze and not respond to a command properl

Yeah - I started off using a 168 and was using 1 temp and 1 heater with bang bang control and still had bad issues with resets - However I did not try the no acceleration mode - which does not make for a happy printer anyways.... I had to quickly make up a board last night with a smt atmega368 I happened to have laying around to make progress - - perhaps we should mention that it works on 328's

You might want to check to make sure the firmware is reliable on a 168 even if it fits in flash - the most recent version I tried - initially with a 168 - after a few commands the chip would reset itself - I think due to stack running out of any additional memory - once I moved to a 328 the problem went away.

I am loving the teacup firmware so far - and almost to the point where I can print
I have a minor issue in the firmware - I am running my own custom electronics and in mendel.c the SPI init comes after setting up stepper pins. I wired a stepper to the MISO pin and I have to comment out the spi init so that MISO does not turn into an input. Perhaps moving the SPI gpio init stuff before the steppe

Hi, I have some very nice industrial bipolar stepper drives, they accept a 5V open collector input that is optoisolated.
They are rated 24V to 40V input, with adjustable micro stepping at 1/2 1/10 all the way up to 1/100
They have adjustable current limits from 1A to 4A in half amp increments.
I am looking to sell 4 new drives in antistatic wrap for around $200.
I will guarantee them for 30 D
