Quoteansisl guys I need help! I'm having no luck with proximity sensor (sn04-p) - it is not stopping Z. Its connected to Z- (Z+ empty), light is coming on upon proximity, sensor outlet is giving out voltage once in proximity, BUT G29 isn't registering it I did reflash with Marlin found at the start of this thread. Also tried feeding it 12v from board and using resistors for sensor output to reduby steaneb - Prusa i3 and variants
For those having trouble with prints not centre on the bed have a look at the offset settings in Marlin for the bed sensor and nozzle. I had the same trouble, and noticed the offset amounts were damn close to the distance the prints were off-centre. Reduced the offset and prints are now centre. Not sure if that's the right way to do it, but it works for me. From what I can see it has only moved tby steaneb - Prusa i3 and variants
Quoteansisl Hi guys! I've also just finished assembling this printer. Got two problems :/ 1. imo my proximity sensor is faulty - light comes up then it's close to plate but it never stops the Z motor :/ ('old' Z endstop does when using with G29). I've tested it from a quite safe height with different aluminum 'targets' - it just keeps going down. I did shorten its original cable quite much but Iby steaneb - Prusa i3 and variants

Quotejbehan 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? JB.

QuoteIBaz 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...yegby steaneb - Prusa i3 and variants
Quoterejaak i don't know if this will help, but, i finally was able to get my prints centered in cura by adding "G92 X-15 Y120" right before the M117 command in the start gcode. for some reason in Repetier Host, its "G92 X-18 Y120". dead nuts center.

Quoteveaceonee QuotegatorNic Interesting, maybe some shady buisness going on over at 3dprintersonline.com. Where I bought mine. Several days ago there were 43 reviews, with several new ones being one or two star. Those have since disappeared, along with others. There is only 26 reviews now. I mean there is still a couple 1 stars up there, but 17 review difference is quite a bit. No shit theby steaneb - Prusa i3 and variants
QuoteUkemaxxer Quotemagiske @Ukemaxxer I belive that dumping the FW is a bit overkill since it's = Marlin. And as long as you keep an updated Configuration.h, you should always be good. It was more just to keep a backup of the original in case I needed to reinstall it. I've been sent some later code from a migbot contact in Canada. Uke, are you able to upload the new version?

QuoteInvictus I'm assuming your proximity sensor is mounted correctly (the one in the picture is upside down). The instructions included with the printer that tell you to mount the proximity sensor 2mm higher than the extruder tip don't match the Z probe offset in the firmware. The probe should actually be < 1mm higher than the tip of the extruder. Here's how I got mine properly setup: Do aby steaneb - Prusa i3 and variants
Quotemagiske Just ordered one. Looks good for the price. And tinkering to get it to work "perfect" is part of the fun Just noticed this post. Be keen to see how it goes.by steaneb - Prusa i3 and variants
Quotemagiske Where did you find the extruder frame in aluminium ?? Contact the guys from and they should put you onto the wholesaler/ dealer. Apparently the dealer also stocks other parts, but I've never been able to get a list out of him. If you do manage I wouldn't mind a copy.by steaneb - Prusa i3 and variants
Managed to finally get the stl files for the printed parts. If yours arrived with missing and deformed parts as mine did, you'll probably want a copy. FYI the extruder stepper frame is available in aluminium and is worth having to contact the dealer to get one. Cost was around $8USD.by steaneb - Prusa i3 and variants
Quoteevetanlm This is the Sensor they have send together but the issue is, can't sense the glass plate. maker will only say alu plate is nicer. The sensor has a range of 2mm. The thinnest I've seen the glass is 3mm. You will probably have to find the model with a longer range. I've seen this type with a 5mm range.by steaneb - Prusa i3 and variants
Quotejcabrer You know how the old saying goes: "You get what you pay for." The Migbot Prusa i3 is one of those ridiculously inexpensive 3DPs coming from China. It has a few good things going for it. Technical support is not one of them There is no B.O.M. per se. Only some PDFs and images to guide you in the assembly process.
