I'm implementing auto bed level function to my old printer.
But I'm stuck in setting z probe offset.

I've done every procedure of the +Thomas Sanladerer 's video, but I got more than 1mm gap from the bed after I finished setting. That gap is not proper value, I think, can be adjusted by slicer's z-offset option.

Here are the log from G29 leveling procedure.
-------------------------------------------------------------------------------------
12:45:16.301 : Bed x: 10.00 y: 30.00 z: 0.37
12:45:21.681 : Bed x: 140.00 y: 30.00 z: 0.96
12:45:26.821 : Bed x: 140.00 y: 120.00 z: 0.88
12:45:32.539 : Bed x: 10.00 y: 120.00 z: 0.11
12:45:32.545 : Eqn coefficients: a: 0.01 b: -0.00 d: 0.32
12:45:32.547 : planeNormal x: -0.01 y: 0.00 z: 1.00
12:45:32.549 : echo:endstops hit:  Z:0.11
--------------------------------------------------------------------------------------------
And 
Z_PROBE_OFFSET_FROM_EXTRUDER -0.7

I don't think the result what I've got is normal.
What am I missing.

And one more question,
What's the 'z value' means from G29 or G30 probe?
I want make things more clear.

Thanks.

+Peter Hertel I don't think that issue relevant with mine.
The problem I have is that I can adjust z-offset no matter how I change Z_PROBE_OFFSET_FROM_EXTRUDER value in firmware(at least, it seems like that). It has always about 1mm gap between nozzle and bed.

How does nozzle size affects bridging capabilities? My printer came has a 0.35mm nozzle, and it only recently struck me that this could be affecting my bridging, which I never really got that great. Perhaps bridging would work better with a bigger nozzle, like 0.5mm? It seems to make sense - the thicker extrusions should be stronger. But has anyone tested? (I use Slic3r.)

I started out with a .35mm nozzle but as time went by i moved to a .5 and even a .7mm nozzle. I did this primarily to reduce print times . I have never had trouble with bridging reasonable spans but i would have to say a larger diameter nozzle may improve performance.

Well not 3D printing in the conventional sense ....
This designer believes we can balance mass production with nature by growing and pruning trees into furniture on a large scale.

I see. I guess that's a valid reason to want to go back to the smooth rod. I had a little trouble on my Y axis but that's been worked out for some time now. I personally haven't noticed a difference. Everyone has their preference though.

Cool model but color choice is a little bit cheesy though ;)

Stratasys wants a closed eco system for their printers.  I guess MakerBot might not be very open for very long since Stratasys bought it.

at least with printers you can choose not to buy the annoying ones.  with cars it's a consortium of all makers (there are no open source cars that i know of)

Just tried out Slic3r 1.2.9 stable over 1.1.7 stable and for some reason I'm getting over extrusion on the perimeter , so as I went back to 1.1.7 issue cured.

Any idea's what I may be missing?

I have downloaded 1.2.9 and had issues as well of prints start in the middle of the bed menus overlapping and such. Didn't had a chance to look over the settings, but I hope that I will have time to play around with in later this week. Back to 1.1.7 as well :(

Considering building a Delta Printer as my second printer. Which of the Delta printers would you receommend to build that has some good info & help. I have access to 30mm x 30mm Aluminium Extrusions. Don't have access to the 20mm x 20mm extrutions.
Would like your opinion ?   #Deltaprinter   #3Dprining   #RepRap   #3Dprint

I am using a spiderbot and am very happy with it. I don't know if the design is open source...

1st attempt at a critical piece pulled the tape off the glass. In desperation, I'm trying gorilla glue. Spread a modest layer with a blade and quick dried with a heat gun. Started print while (unheated) bed was still warm. No shrinking/curling so far.

Question is: What are the chances I'll get this off tomorrow morning when it's finished???

I have tried Painter tape, the problem is getting the print off at the end. Always have to replace the tape, even if the print is printed with a cold bed.

I have a commission to print an Auryn medallion from the never ending story. I've found an open source stl file, but it lacks the scale texture.

Is there a software or trick out there that would allow me to add some snake scale texture to a section of a print?

Quick question. My one printer has been printing for over 2 years without trouble. (At least not this) it prints and after a random time the fans spin down for a few secconds spins up. Anf then the print continues but it will be misaligned. I suspect its the ramps board fuse thats resetting. But I cant help thinking its the psu. Anyone seen this.

I'm thrilled from the mechanical quality. Looks like it's definitely a quality product.

Hello,

I'm having a lot of trouble getting a good first layer on my printer. It was working for a while but then I messed up the three leveling screws under the bed and now I can't get it quite  right again no matter how many times I try the trick with shoving a piece of paper under the nozzle and tightening until it bites.

Do you guys have any advice? Also, is there any place I could pay to come out and level it for me?

The first line of filament should be a little bit squished by the nozzle. It shouldn't be so squished that each lie overlaps each other, but it shouldn't be too beady either.

Today I modified the firmware of the #OpenBeam #KosselPro for the #E3Dv6 end effector and was able to print a calibration part. I had a lot of trouble with wobbeling due to the cracked arm mount points. Also the screws came loose all the time. I published the design on github. To all KP owners: Please download, build and improve it!!!

I just uploaded to Youmagine #PowerCode design, this 3D printer is a variation of the Prusa I3 some advantages, Spain already has a long way.
The PowerCode is a varitaion of the Prusa I3 to implement certain avantages.

I was recently asked to make 500 whistles for a local college to sell. My concern is the safety of the plastic. I always print with Toner Plastics PLA and would like to stick with it if possible but I don't want any issues with illess. Any suggestions or can I stay with PLA?
