My smartrap build and easy Z offset adjustment June 01, 2014 01:57AM |
Wow! Why haven't I seen this forum before? I could have gotten help and ideas while I was building my poor man's smartrap. Please check it out here.
My smartrap won't win any beauty pageant but it prints!
Anyway, I just want to share this little piece of information especially to those having a hard time fine tuning their z offset.
I'm not sure if the hole on the arm stopper was meant for this but I found it to be a very effective way to fine tune the z offset without changing any firmware configuration or slicer settings. You still need to get the offset to be within the 1.5mm range first. After that, all it takes is a turn of the screw to adjust the z-offset

That hole was originally meant for a small screwdriver or allen wrench to asjusta grub screw in the arm, but I guess this way works too.

Oh. That explains why there is a hole in the arm, too.
Well, it's a happy accident then.

Thanks for the M555 tip but since my smartrap is not tethered to my PC, the screw method is my friend
I agree that change is constant so our smartrap will never be finished because I'm pretty sure that we will always find a way to improve or customize it.
Print! Print! Print! Hahaha

Don't you care about fan blowing on your prints?
I shared this with duranza on this thread but I'm wondering why there's not too many people here caring about fan blowing on their prints.
Don't you even have a need?
Well, I did and here's what I came up with. I'm redirecting about a third of the fan's airflow toward the print. This is so that I don't have to use two fans (one for cold end, and the other for the print) and keep the carriage light.
Does anyone have a better idea I could try? I'm willing to try even a two fan configuration if it will allow me to print something like batman ears well.

I use only a 30mm fan for the hotend that is running full speed and powered directly from the 12 volt supply, and if needed for cooling prints I use a separate fan on a stand that I can place where I need it and run it from the automatic fan pins on the RAMPS board.
Not all prints need a fan on the prints and being as the SmartRap is a little hard to mount a big fan on for cooling the prints, I find this is the best option (for now)

Aaah... we have the same idea of hitting two birds with one stone.
I might have tried it if it was for a j-head.
On a separate note, I wonder if Serge will move his stuff from thingiverse to youmagine. You know, after the makerbot was accused of stealing the designs of people.

I would agree with that, anyone wondered why I haven't put anything up on thingiverse? The parent company is out to do us all, trying to patent our ideas and stop us using them. Real corrupt ideas in my book, I wont support them in any way.

for the moment i don't touch the fan speed,
i'm just put this deflector on my smartrap after the third layer !
(but i'm quite sur it can be controled with marlin)

OK, my fan is way to close.
I'm jumping between Slicer and Cura every now and then, i like the simplicity of Cura.
I have played with the Fan speed settings though i'm sure the fan is just to close
You can also print a cowl for the fan so that the breeze is directed to where you need it.
I have done that on a few of my i3 machines and it works well.
The photo shows two 80mm fans and they follow the printed part as it is being printed. Also the creed LEDs follow the part as well.
