Hey guys, I have got my migbot all set up and printing pretty good at this point, bed centered in firmware, auto-leveling running properly. Just one issue everything is printing mirror image from what it should be, if I print something with text on it it comes out completely backwards. Any ideas what the issue might be? I can say that all my stepper plug wires are in the same order, all plugs on the board are black, green, blue. red. all plugs on the steppers are black, blue, green, red. so I'm kinda lost

No I have not, I have just been circumventing it by mirroring in the slicer, but I would not like to rely on this and actually get it resolved for real.

I would appreciate input about the bed leveling problem I am having (or think I am having). After bed leveling today the first layer in the middle of the bed was OK. The 1st layer on the right side of the bed was so tight that the extruder motor started clicking. I killed the print and issued a G28, it was OK. I checked the distance between the Y-axis rods and the X-axis rods and they were different from side to side. I adjusted them to be the same distance. Issued G28 and adjusted the nozzle tip to be 0.1mm above the bed. Restated the print and after the bed leveling was complete the 1st layer is spot on. The X-axis was out of level about 5mm from side to side.
Does this mean that bed leveling will not compensate for an X-axis that is not parallel to the Y-axis?
Has anyone else observed this behavior?
Any suggestions on preventing this? The printer had just finished a 17 hour print job which went without a hitch.
I have wired the Z-axis stepper motors in series because I had problems with missing steps when they were wired in parallel.

Hello All,
I have the Prusa I3 kit and after a few set backs (Missing Hardware - Bad SD Card) .... I finally have everything together except 1 thing
I purchase the Auto Leveling kit sensor with this kit but I do not know where to wire it to?
Can someone advise the correct slot to install the OMKQN Sensor to?
Thank you,
J

It plugs into your z- endstop. Also replaces said endstop.

Alittle loss here. I think I am on the last step of getting my printer to work (been busy with work so couldnt touch it)
I have the sensor package. I havent leveled the bed yet with it. I mean, when I level the bed, do I need to set any offsets? How do I know what they are?
Wish there was a more simplified step by step for the whole thing. And maybe I am just flustered too.

I am having a recurring problem with the hot end. The Throat continues to become loose. I have replaced the grub screw. I tighten it and use medium thread lock compound but it still gets loose. When it gets loose it starts hitting the object being printed and will knock it off, or the nozzle will hang inside an object and the printer skips steps on the X Y axis. The entire hot end has fallen out and made a big mess, it was hanging by the wires.
How are you keeping the grub screw tight?

I replaced the whole setup with [www.ebay.com] The hotend screws right into it.

How did you secure it in the extruder frame?

Hi All,
Just wondering what lubricant you are using on the slides and Z-axis threaded rods?
Thanks,
Michael

For the Z-axis I use this [www.amazon.com]
For the X and Y I use 3-in-1 oil. One drop and then move the bearings over that, Then take a towel and remove the remaining oil from the rods.
Use a toothpick to apply the Moly Plate. Lower the Z-axis and apply a touch above the Z-axis bearing and raise and lower the axis several times to spread it on the threaded rod. Once that is spread move the axis up midway and repeat. raise the axis fully and wipe any excess off the threaded rod. The Moly Plate goes a long way. The threaded rod will be black from the Moly Plate. I like Moly Plate because it does not attract dust.

Thanks. We're in a dusty environment so I need something which doesn't attract the dust. I can get 3-in-1 locally, but not Moly Plate. By the looks of it, it's a regular molybdenum disulfide grease so I should be able to find a local equivalent. What sort of consistency does it have? (I can't find an NLGI rating for it in their datasheet; see [en.wikipedia.org] for equivalent consistencies) Cheers, M.
