ok so I've investigated this some more and I think the issue is in Sailfish
The gode looks fine verified using Rap3d Visual code editor.
at the poiint where the model switches to the second...
ive attached the g-code file
Folks, Ive been trying dual printing for a change.... but hitting some issues.
I'm running Saolfish firmware and S3D as the slicer.
managed to calibrate the tool offset by hand since Sf seems to...
Folks,
Thought I'd share my findings on the CTC Dual...
I finally have good consistant results from this puppy but I needed to make several essential modifications.
Essential mods/fixes
Glass...
try rotating the model 45 degrees and print, see what the error is then.
I think new gears will improve things for you.
I agree 100% about the bearings.
I switched to oil impregnated brass bearings and found that it was hard to get good free motion in the x and y carridges.
The brass bearings have a much tighter...
nope, ctc uses 17 tooth gears.
But I guess you could switch to 16 or 20 and re-align the steps per mm in software... but easier to just get 17t gears.
If anyone is having the " my circles are not round" issue on their CTC.. here is what I went throught to fix it.
it can be caused by Y axis backlash... i.e. the y axis travel is not 100% the same...
This http://www.thingiverse.com/thing:1071695 works great... best tensioner out there
Looks like a good method, thanks for the link. I'll try this also.
Nice one, ill give it a try later.
My prints are 2% smaller on the y axis, so I assume one just needs to modify the step/MM by 2%.
I let you know how it goes.

Got a small problem... my test 20mmx 20mm cube is comming out 20mm (x) by 19.7mm (y)
I thought it was belt tension so I re-did the belts but got the exact same result.
Can the offset be...
Regarding GPX, I use Windows 7 64 bit. GPX still runs on it just fine.
But I had some issues getting it going at the start.
My solution was to use slic3r "post processing script" to define the...
Sailfish gets my vote.
Just last night I noticed my print was overheating and I was able to adjust the head temp (downward) during the print and saved the model from failure.
Print speed can be...
Nice job.
I'd remove the yellow sticker on the front, will make it look cleaner.
If your carefull you can just slacken off the side screws at the top/side, even take some out, the wood is flexable. This will allow you to make enough space to get the rods out using the open...
Got my CTC last week,
Is it cheap... Yes.
Does it print ... Yes
Does it need mods .., oh yes
But to be fair for £270 and free shipping what do folks expect.
Mine had a faulty heat bed,...
ok.. feeling stupid...
RTFM Ray !
I entered the bed size alright... but I ignored the "Oirigin" inputs... I incorrectly assumed these should be the front left.
But obvioulsy the 0,0, is in the...
update.. I frigged it by adding extruder offset of x=113 and y=75
but i have the feeling this is not the best way to correct it...
ahem... OP here... :o
I erased the EEPROM but the offset is still there..
So do I need to re-flash again after EEPROM erase?
FYI, I'am creating the .x3g code using the start/end G-codes...
as title.... I've upgraded to Sailfish
Managed to get GPX running with Slic3r, thats fine.
but my prints are not starting in the middle of the bed,
instead they start to the top right (as I...
Ok, thanks.
I've examined the PCB layout and have come to the conclusion that there is no substancial temp offset between the chip and terminal blocks... though it's not a good design cooling...
Not sure I follow, isn't the hot end already shorted out?
Interesting article here

The thermocouple measures difference not absolute temp.
There is a hot junction (measurement end) and a...
