New to 3d printing with smartrap need some help Hello all, I have built the version 4.7 and have everything set up, but I'm having trouble extruding. I'm using this hot end with no luck [url=http://www.ebay.com/itm/Low-Cost-Assembled-hotend-0-4mm-nozzle-for-1-75mm-ABS-PLA-bowden-extruder-/331199179895]hot end i'm using[/url].

i'm experimenting with this but when the arm is half way then it already struggles a bit and when the arm is fully extended then the slide tends to block / get stuck

However when I just press manually then it seems to be working just right.

So when the arm is extended the x bends enough to make an angle that gives enough force to get the slide stuck on the friction.

I had the same problem initially but found it easier to lubricate the slider and X-end with silicon spray.
Made it slippery as hell and haven´t had any blocks/stuck since.
I use the J-Head MK5 and my design of the slider but it should be irrelevant in the design.

Hey Talle, can you take a picture of your actual hot end slide. I would like to see how it turned out.

I use Vaseline to make it slide better, but silicon spray works wonders too..]]> duranza Smart_Rap Tue, 12 Aug 2014 13:03:35 -0400 https://reprap.org/forum/read.php?344,365849,393954#msg-393954 Re: New to 3d printing with smartrap need some help https://reprap.org/forum/read.php?344,365849,393954#msg-393954

[attachment 38168 z-probe.jpg]

but there ate a few big fat buts.

if there is PVA glue on the buildplate then that prevends the nozzle from making contact
OR
PLA on the nozzle, that's also an insulator.

Now im not sure if the hot nozzle pushes the PVA and PLA enough away to make contact.

So yes it should be possible, but i'm not sure if this is 100% reliable. And if the buildplate is metal then why not use an inductive probe... unfortunately the cheap ones are bigger then the hotend itself]]> BackEMF Smart_Rap Sun, 10 Aug 2014 21:29:12 -0400 https://reprap.org/forum/read.php?344,365849,393438#msg-393438 Re: New to 3d printing with smartrap need some help https://reprap.org/forum/read.php?344,365849,393438#msg-393438

This resulted in some thinking and since I’m figuring out FreeCAD I decided to explore my ideas there..
And this is the (not so practical) result. Bur maybe someone can remix the ideas?

[attachment 38155 zipslide.jpg]

This is done with the Genie hot end in mind. the PEEK of the hotend functions as a slide.
The mount groove rests on zip ties that function as a spring as well.
and the heatsink is the trigger for the microswitch (and that is also held in place with ziptie pins)

It's a lot inspired by Japanese woodworking techniques. :-D

The main idea is to have the probing pressure fully centered in the slide so that the slide doesn't cause sidewards friction. And all the rest is pure to keep things small.

... just having some fun with FreeCAD

BackEMF, you have just opened up another area to explore. Just when I thought I might get a bit of time to get back to my build ha..ha..
Recently I was asked to design a X end mount that had no servo or movement of any kind, just mount the Genie hotend directly to the X end.
He is manually leveling the bed and doesn't need the head to move to activate a limit switch and doesn't have a servo either.
I suggested using a hall effect sensor to trigger the Z limit from the Z rods, I sent him a hall effect sensor to try out as they are very accurate and very small too, easy to use.
I will post some photos when I get back from the city.]]> regpye Smart_Rap Sun, 10 Aug 2014 17:57:18 -0400 https://reprap.org/forum/read.php?344,365849,393306#msg-393306 Re: New to 3d printing with smartrap need some help https://reprap.org/forum/read.php?344,365849,393306#msg-393306

I tried to print this yesterday but I was kind of unsuccessful due to stop in the hotend.
I belive that is PLA related since my hot-end-fan has been working flawless with other PLA rolles.

What I realized though was that the slide was a bit to thin so it wobbled a bit back and forth, so I´ve widened it a bit 0.1mm and also cut the corners, and made some minor adjustments.

I´ll give it another go tonight and keep you updated.

I've had problem printing it . The first one was perfect and it didn't move front'back..the following went bad and i have too much free move. But it's my fault, i redid it in blender and it's bad !

I'm trying to switch to free cad , but still a little lost in it . Do you think you have some cad files workable in free cad ?

thank you. I'm sure we will make it. It's just perfect to have jhead and huxley together on the same model .

I still need to integrate fishing line point, m5 hole for rack&pinion and two version for 8mm rods and 6mm rods.]]> smartfriendz Smart_Rap Thu, 07 Aug 2014 07:26:17 -0400 https://reprap.org/forum/read.php?344,365849,391866#msg-391866 Re: New to 3d printing with smartrap need some help https://reprap.org/forum/read.php?344,365849,391866#msg-391866 I belive that is PLA related since my hot-end-fan has been working flawless with other PLA rolles.

I haven´t tried to print this yet but I made a slide for the J-Head MK5.
I´ll try to print it tonight and see if it fits.

Anyone want to try my untested version before that just let me know.

The original files had a .1mm gap between the main plate and the slide plate already built in.

Hey Reg, I think what would help on the Genie parts is to put a straight fillet on the corner of the 45 degree slide part so that only the sides make contact.

Update:

Wow very cool fan cowl integration. I like it.
Updated version now ready:



All parts

Fan cowl

Sliding base

The sliding base has been designed to be tapped with a M3 tap. Print this small part at 40% fill or more.


Thx for this!
I really like it! :)

Just a quick question.
Has the main part of this been edited aswell in the latest version?

Printed just the sliding base and that is a great deal smaller than the original part in my print.
or is it just my print that is bad (made 2 copies).

Main part is with 100% fill and Sliding base with 50%.

THX

The main base is the original file.
The other two parts are made to fit as close as could be from just measurements as I didn't have the raw file for the main part.
The parts all fit together nicely on mine.
All parts were printed at 55% for mine prints.
I will try and make it a bit tighter so that if too tight a file may be needed to trim it up a bit.
