Topic: Modded Ord Bot Hadron Build - 10" x 10"

Hello All!

Wanted to  show you the Ord Bot Hadron Build I’ve been working on!

First of all, kudos and many thanks to Bart Dring for the design and all of the other great folks at Inventables where I procured most of the components, Step Motors, and Makerslide.

Thanks also to Adrian for his expert guidance and Serin; for hers was the first Hadron I’d seen and that inspired me to build this one.

I was impressed by the Hadron design the moment I saw it, but wanted a 10”x 10” build platform…searched around at RepRapDiscount,  but saw they did not offer one.  So, in looking at the design I figured it wouldn’t be too difficult to scale it up.

I started by going to Bart’s Buildlog and found the MOST WONDERFUL CAD files for the entire build!

http://www.buildlog.net/wiki/doku.php?i … he_ord_bot

Using this made the project so much easier.  I grew the entire linear component lengths by 2”, then started my calcs on what I would need to buy.  Inventables shipped the Makerslide and other stuff the same day, and soon:

Measuring and cutting was easy.  Luckily, I have a decent milling machine to square the ends…

And soon the framework was complete!  Awesomely brilliant design by Bart Dring!

The gantry is amazingly rock solid…a one finger lift on one side with no perceptible lag on the other end.  Bought a 10” x 10” heated PCB Bed from MakerFarm and the build is almost complete!

Still waiting for my RAMPS and the power supply for the 18A PCB Bed…otherwise, have a Bulldog XL from RRD and an E3D v6 on the way from Tim at Filastruder.

BTW, saved about $100.00 doing it this way; but you need access to a decent milling machine and band saw...and it took about 6 hours longer than a standard kit build.  I would be happy to supply a BOM / source list and .stl files for the printed parts to anyone who is interested…just PM me.

Still a bit left to go, but wanted to share and wanted to double-thank everyone for their assistance and help, either directly or indirectly!

Cheers!

Well done on the build. I personally don't think the 6 hours extra work means you saved a $100 since I'd hope you consider your time is worth more than 17 an hour.. But you had fun and got a custom build out of it and personal satisfaction which is intangible value for sure.

Now to the fun part - dialling it in smile

Re: Modded Ord Bot Hadron Build - 10" x 10"

Adrian, Absolutely correct on the time spent / financial part.  In fact, considering the extra time I spent at Fastenal running down the M5 and M3 bolts, etc.;  If I had to do it again, I would strongly suggest buying either the mechanical or plus complete build kit from RRD and just getting the extended Makerslide and base extrusion.  The extra work of making the X gantry carriage, etc. was a bit of a pain...

But, as you say, the satisfaction of building is always grand! 

And the dialing-in fun is indeed yet to come!

Thanks!

Shiny!
I see you're using the foot raising devices, any particular reason for em?

This is a crowd funding thing that I'm running: http://www.gofundme.com/bvi140 It's for pretty selfish reasons tongue

Re: Modded Ord Bot Hadron Build - 10" x 10"

Nice catch!  Two reasons:

A. The 62 in/oz stepper motors supplied by Inventables have dual-ended shafts, so I needed the extra clearance;

and

B. Currently, I plan on screwing the extenders to a plywood mounting base rigged up to ball-bearing drawer slides(lockable). Then I will have a hinged open-ended acrylic enclosure which will let me slide the whole business out for access when necessary. The slotted extenders should help to keep the machine planted firmly while the build platform dances to and fro!  Also, the slotted feature will enable me to remove the machine easily if I need to for any reason.

Not fully nailed down on the enclosure design yet...open for other ideas!  Maybe put the enclosure on drawer slides and leave the machine on a static mounted base.

Probably need to get the Beast running before I head down the enclosure path!

Re: Modded Ord Bot Hadron Build - 10" x 10"

Update...

Been away from the build for a few days...My day job sometimes gets in the way of things!

Oh well...

Did some work on the build plate support.  Designed these nifty screw / spring holders; the threaded portion is on the bottom and keeps the screws from wobbling:

And got the X-carriage mounted...still need to mill the slots and drill mounting holes for the Bulldog / E3D...put drive belts on just for fitting / alignment; will remove them for initial powering up once I get the RAMPS set up...

Re: Modded Ord Bot Hadron Build - 10" x 10"

Update...

The Beast is starting to come to life!

Finished hooking up most of the wiring...photos to follow; many thanks to Ian Johnson for suggesting that all Stepper motors be wired to their respective drivers before trying anything!

All is good on Homing and direction of rotation is good; but I'm getting a distinct backlash of sorts when the Y axis homes:

https://www.youtube.com/watch?v=Hk2FRIK … mp;index=1

The X and Z stop close to dead in their tracks when the end stops are hit, but only the Y motor does this...any ideas?  I looked through my configuration.h and Adv.h but couldn't see anything obvious... 

Any guidance would be appreciated!

Re: Modded Ord Bot Hadron Build - 10" x 10"

Well, installed new stepper drivers today...to no avail!  The strange back rotation still exists, but only when I hit the "Home All" button on RH....again, when homing each axis separately, it works fine (sigh).

Any further ideas?

EDIT:  Update...just noticed that the effect occurs on BOTH the X and Y motors upon auto homing.  In other words:
X homes first, endstop hit
Y homes next, endstop hit
Then, BOTH X and Y motors wind backward at high travel speed, as if they are going to the max of the printbed!
Then, Z homes, Z endstop hit - Done.

Could the firmware be interpreting these as MAX ENDSTOPS?  Any help would be appreciated.

Re: Modded Ord Bot Hadron Build - 10" x 10"

FIXED!!

Many thanks to Adrian and Ian for letting me borrow their configuration.h settings to compare to mine!  Also, thanks to Wardjr for pointing me in the proper directions through this whole process.

The culprit was in the "Manual Homing Switch Locations" lines where the X and Y values were set to 0 vs being set to my bed dimensions of 250 and 250...guess I just thought 0 made sense...

What a learning experience!  I hope I soon can be as much help to others as you all have helped me!

EDIT:
IT'S ALIVE!!!

Did PID on the Hotend and PCB bed...all good!

Printing a test cube!  Almost can't believe it's working!

Note to all intending to use a Solid State Relay...Use a heat sink and use active fan cooling(I did not).  The unit will fry without it!  Oh well, another is on the way from Amazon...

Now to start the final calibrations...

Re: Modded Ord Bot Hadron Build - 10" x 10"

Well, finally deployed, calibrated, and in an enclosure that I know is a bit large, but I wanted to keep to standard pre-cut acrylic and wood pieces! 

Got to work on a better spool holder...

http://i.imgur.com/o1pSoJU.jpg

Still waiting for my final SSR...turns out that a 25A is not really useful for a heatbed drawing 20A at startup; ordered a 60A...so in the meantime using a 12V / 30A automotive relay with PID disabled.  The only downside to the standard relay is the +/- 2-1/2 degree fluctuations DO make a difference in the printed wall surfaces; almost like a Z-banding effect...oh well, it's only temporary.

Nice case, but what is with the purple leds on the side? Arc Reactor?

Re: Modded Ord Bot Hadron Build - 10" x 10"

Two of 'em...had to do something with the Palladium-based versions from the Mark 2 & 3 suits...

But seriously, that whole unit on the side is the "Ready-to-print Brainbox" from MakerGeeks.  All-in-one ATX power supply with pre-wired RAMPS 1.4 and dual cooling fans (and purple LEDs).  Worked out really well as I wanted to keep the electronics out of the enclosure.
