GeraldO's Build

[GeraldO]

I forked and uploaded the code to: https://github.com/gjorban/Repetier-091 ... 91.ramps14

Just as a reminder, since I don't have a built printer I could only test the RAMPs so far as to ensure the LCD and encoder are functional and that it boots up. YMMV!

EDIT: I don't suggest anyone try to merge/do a pull request on this as it's currently hard coded to work with RAMPS and will fail to compile for Rambo!

[analog_banana]

Thanks!
It compiled and went onto my Ramps fine,

Everything's working that I can check with that firmware:
motors, fans, heaters are running. I can't do a complete test yet due to hotend not reaching temp.
The hotend may may just be an Eeprom setting I need to learn - or something in the firmware -
or hardware issues!! I will try to find out..

Nice Work!

Well my replicator was good at making people deaf so I'm hoping to blind people with the orange awesomeness instead

The masking tape is coming off and it looks fantastic!

That orange looks good on the black background.

Construction getting kind of slowed now because I need to source some M3x5 bolts for the Astrosyn dampers I bought from Cope. I have a box of 100 M3x10 bolts so I may just grind down a few to size instead of trying to find some M3x5s locally (impossible in Vancouver on the weekend).

That being said, all of the masking tape is off and the base is underway!

The more you take pictures and the Orange shows up the more I like it. Is that a florescent Orange?

[GeraldO]

Yup! We used acrylic fluorescent orange with an undercoat of pure white to help it pop out.

Pop out is a good description. I can't wait to see it fully assembled because this has to be the most colorful build I have
seen yet.

[GeraldO]

I managed to find some M3x6 bolts, which were good enough to mount the motors to the dampers. The ladyfriend and I managed to complete the base. Tomorrow we raise the towers and beyond!

[AndThenSome09]

It's looking good! Make sure to take lots of pictures along the way, we love pictures of the build around here!

[GeraldO]

Got the towers up and am assembling the u-joints for the carriages. There's going to be lots of sanding as the aluminum joints are not fitting into carriage u-joints at all.

I have trick laser arms in the mail so I guess I can afford to just make it work for now and replace them during the week.

[GeraldO]

After futzing with sanding the cams I decided just to wait until the Trick laser arms arrive early next week :p

[AndThenSome09]

Trick laser arms are perfect! I had ordered them in the middle of my build last October, I still did all the sanding and filing just to see how well I could do it but still never tried the stock arms, as soon as the TL arms came in they went straight on the printer!

[GeraldO]

Well here's where we got to before stopping with the cams.

I also started getting a head start on soldering up the connectors for the hot end and the HBP. RTV is curing and most solder joints are ready for JST connectors. Will resume after I get those new delta arms.

[Eaglezsoar]

Looking Good!

[GeraldO]

UPS has utterly failed me and am waiting on them to deliver the package. They failed to read my apartment number on the address slip, claiming it wasn't on there (but the shipping notice from Trick laser had it). Maybe I'll have them tomorrow?

Really disappointed that they dropped the ball this hard, and frustrated because I was hoping to be printing by tomorrow!

[Eaglezsoar]

And after all the taxes you have to pay for them to deliver to Canada and they do this?
I would be POed beyond words.

[GeraldO]

Oh yeah, I have to pay duties in excess of 50% of the price I paid on top of this bullshit!

[GeraldO]

Told UPS to go f**ck themselves and have to pick the parcel up from the airport. Construction resumes next week!

[GeraldO]

Alrighty! Back to the build! I didn't have much time today however, I *DID* get the carriages and trick laser arms attached. I also bought the "add an inch" plates for the tower carriages because who doesn't like an extra inch?

Here she is! The bearings are all setup and tensioned with the carriages moving freely up and down but in no other direction. Hopefully I'll be printing this weekend!

[Eaglezsoar]

I really like the way that orange pops! Quite nice and a very good job!

[GeraldO]

Success! Machine has been built and powers on! Vrefs were set way WAYYY too high on my DRV8825s but I think I'm in a good spot w/ theri trimpots. Tested heating and it maintains a stable temperature! Motion is still a bit weird but I haven't calibrated end-stops or z-height yet.

Pics will be up once it gets cleaned up a bit-- but it looks great!

[GeraldO]

Well, I don't have pics of the frame but I'm fast calibrating this thing and after a few days it's starting to look like I can get good prints out of it. I didn't even need to adjust the delta radius!

Until I get more exterior pics, I took a lot of time to organize cables in the electronics bay. It needs a fan to cool the DRV8825s but it's nice and clean!

[Eaglezsoar]

I do like those heatsinks you are using. They look great and I bet they work good.

[GeraldO]

They're doing a pretty good job. Keeping the steppers warm to the touch, but not hot. My extruder is cranked up a little higher and is uncomfortable to the touch but not super hot.

That being said, I'm running into some problems right now with my layer alignment. I seem to have my retraction dialed in but my layers are all over the place. Take a look at the pic below of the hollow calibration pyramid:

Retraction looks great but the layers rarely align. Here's what I've checked so far to try to resolve the problem:
= Retension belts (they're very firmly tight now)
= Double checked vrefs aren't set too high (heatsinks are warm but not overly hot, no thunking audible for missed steps)
= Using trick laser arms so I'm pretty sure I don't have the delta arms blues (no arm binding and the effector plate moves freely in all directions) I'm also using their zero-lash straps (rubber bands)
= Ensured freedom of motion for the carriages (eccentric cam adjustments) and ensured that the carriages can only move up/down and not side-side or rotate at all

Any help or insight into the problem would be greatly appreciated -- it's so close to being 100% awesome!!
