Does anyone have a better design for the layer cooling fan duct?
Seems that the outlet on the standard one is just too far away to be fully affective. I notice it most on overhangs with slight warping of the layers. A better cooling fan duct should help I believe.
Unfortunately I'm not adept enough at CAD to be able to design something myself.

Found this one out there somewhere...yeggi I think. It's still an arse to print. It seems to fit a 'little' better.

Has anyone found an aluminum extruder mount for this thing? I know it was mentioned very early in this forum (first page) but haven't seen anything on it since. I see there is one on flea-bay for $27 but that seems a bit high for what it is.
Also, I was looking at this...any thoughts?

I was lucky to get the aluminium version of the attached stl from Leo (had to pay for it) as the printed part in the kit arrived split. That only took about 10 emails. I haven't been able to find it yet but will post if I find it. There's some similar on aliexpress but it depends how much you feel like paying I guess.
Seems like our close friends have Migbot printers back in stock....the drop kicks couldn't lie straight on a plank.
cheers

Thanks mate but I have already found that one. Was hoping for something that would either be closer and more direct on the print layer or encircle the nozzle and blow from different directions. I have found many for other printers but nothing seems to exist for the Migbot. Shame as its one of the few things now that seems to let me down.

This one could probably be edited pretty easily to fit. Blows from 3 directions

Oops! Released the magic smoke this morning, going to order a board with separate stepper drivers. I don't really know how the smoke got out, I was in the middle of a 2 1/2 hour print and the X axis stopped working? Maybe it got over heated? I don't have cooling in place to the board. I tried another stepper plugged into the X port and no movement. Dang it, had it printing pretty well too.

Ordered an Azteeg X3, anyone know if the Migbot LCD controller will work with the Azteeg X3? Everything else is very well documented. I'm in the process of drawing up my own version of the Prusa style printer and the Azteeg will go on it. I'll be using parts from Open Builds.com and some parts cut on my CNC machine.

So, the fact that my MKS-Base V1.3 controller took a dump, is driving me nuts. I can't figure out what happened. I don't see any physically burnt components and I didn't smell any magic smoke. I read on the Wiki page that there is a recoverable fuse on these boards, anyone know where it is? Also, I want to check the voltage at the X axis, do I just put the red probe on the current pot screw and the black probe on ground (USB housing)??

Anyone have a problem with width changing when going to .1mm prints? So I have been printing fine with .3, .2. Decided to try a .1 layer height on a test cube with the same settings and for some reason it is about 10% bigger in the x y direction. z seems about the same. Not sure what happened, because we're not talking about a small discrepancy, its a big change. Overall the prints are clean, but this new width threw me for a loop. attached some pics.
.2mm on the left, .1 on the right.

Anyone else get an email from someone named Caferlin from China TL Maker Electornics Co,.Limited promoting the site [www.aliexpress.com] for 3d printers?
Looks like they are now selling the Migbots under a different name

Is anyone else having with Windows 10? I knew I shouldnt have upgraded.
I upgraded my laptop to Win10 and the only issue so far is there are no good drivers for my Intel graphics card yet. That seems to have affected Cura a bit where if I have multiple items loaded I can no longer select individual pieces to move them around. I believe its something to do with the color depth bit setting in Windows based on some Googling, but because the drivers are not working so I can't test out anything to be sure.
I have not tested printing with the USB as I assume that will have the same issues as Windows 8/8.1 - sticking with the SD Card, which seems to work better for me anyways.

SOS, have a quick question, as now my old prusa can't read any program and also have a cracking sound is it normal? anyone experience this before? is it because of problem with motherboard? as i'm able to move the axis no issue.
Not reading programs how? Sd Card, USB?
Where do you hear the "cracking" noise coming from?

Not touching it until atleast Sp1 comes out.
What are you having an issue with?
It wont connect. It sees the printer, but can't connect. Pronterface is doing weird things. Upon doing more research, it is a known issue with USB serial drivers.

So the whole j-head jammed up. Took it all apart and saw that the spring mount on the extruder is cracked. is there an all metal replacement available?

Was looking at those. Would love to find someone in the US so I can get it quicker. Thanx though.
You could always upload the the printer parts to shapeways, sculpteo or another service and get fast shipping. Not sure what their turnaround time it. Obviously just a temp fix printed in abs until you can get a metal one, but could be an option.
Usually though I find the epacket delivery from china pretty quick though.

veaceonee, I believe the reason it broke was that it was printed standing up. You can see how it split at the layers. This part is 100 times stronger if you print it lying down, with the large flat side facing the print plate. Also, make sure you use the proper temperature and print it at 200um. I attached a version we modified to make feeding the filament easier. You will need to enable supports for the bottom of the part. The holes should not need support.
