I got me 3D printer, awesome!

Just had my PetG come. So I'm going to make a part of the D-Bot to see how hard it is printing with it.
 
Any idea what went wrong?

On my side of things, I've gone a little nuts on the spec and ended up with a £900 shopping list :D :o
I'm kind of telling myself that's it's all cool, since I was looking to spend about that on a Bigbox anyway and this will be better in certain aspects + the BB now costs ~£1100.

A few highlights:

RADDS/Due + RAPS128 stepper drivers (running RepRapFirmware)
PanelDue (4.3 touchscreen)
Hall endstops
Dual 24v PSUs (one dedicated to the bed)
300x300 24v 300w Silicon heatbed
E3D Titan + pancake stepper / 24v V6
0.9° steppers
And stuff...

Probably going to go with this tweak too, given the larger bed https://www.thingiverse.com/make:229978
Oh, and someone made that DD Titan bracket: https://www.thingiverse.com/make:232789 Looks pretty sweet.

Ah well, YOLO and on with the adventure :)

Wow, nice spec. :)

I've come home to:

Extrusion
Half of the nuts, bolts and bearings
VSlot wheels
And most importantly - a roll of PETG!

Going to start printing bits tonight, and get a thread together.

Yours looks like a mega setup :)

I've found out that the file "1-EndstopY_Bracket.stl" has errors and I can't fix them.

PETG prints the same as ABS. My settings are V6 clone 230 and 80 for the bed.
I will print the rest this week.
 
Starting to print the other files now. Looking forward to the new build.

I think the reason I'm having problems is my printer. When anyone does the extruder.stl are your holes round?

So is someone starting a new thread? I want to see your builds + BOM's with sources. :-)

Your build is going to be assume Uncle Petey.

If I'm mad enough to actually do it :)

Right now, I'm trying to minimise the amount of fiddly little parts that'll need to be printed, saving time and allowing that filament to be diverted towards other parts like the extra front Z brackets.
So, I'll be replacing things like the wheel shims, spacers (1/4") and corner brackets.

Someone in the D-Bot comments (KDan) has also modified applicable stl's to have small sections of the v-groove insert removed around the bolt hole area to allow for T-nuts like these to be used without the little lip clashing with the printed part.
I'd rather go with these instead of the square nuts.

Just waiting for the guy to actually upload the updated files - assuming he will.
 
Any guys with good electrical knowledge here?
I get lost when it comes to a lot of electrical terminology and I'm crap at maths... I can spec you a banging watercooling system though :p :D

Basically, I was looking at just using one beefy 24v/600w/25A PSU running everything instead of splitting the load over two 24v/350w/15A models.

The bed draws max 300w/12.5A.
The RADDS board can handle up to 15A for the heatbed (I think).

Assuming that's ok, what about the inlet socket and fuse choice? (original specced item in the BOM)

I'm crap with electrical terminology as well.

My printer has gone hay wire so I can't join you in making the D-Bot :(

It's either the X axis or they Y-axis. The circles are not round.
I've changed the X axis motor wire and other things and still the same.
 
It's alive!

Wow you didn't waste any time. :D Good effort, how are you finding it?

So I've started the printing process, seems small parts in PETG are going to be a challenge as it stays soft for a while so the quality of print is a bit meh. Started with the endstops for the D-Bot and the taller thinner parts aren't to the standard I would like. Might experiment with some active cooling and see if that helps. Fortunately the part in question only takes 15 minutes to print so I don't mind some trial and error. Will stick some pics up when I get a chance.

Also dropped the extrusion off to an engineering firm today for cutting, got a good look around the guy's workshop and I have the confidence in his ability to deliver to spec. :)

I thought you would have bought the V Slot Extrusion already cut to size?

I'm going to print the parts and hope it hangs together till the new printer can make it's own parts.

@randal what board are you going to use? there's so many
 
Nah, I bought the lengths from Ooznest then get the local mob to cut it. Save a few pennies. :)

Using the MKS Base 1.2 that came with the Tevo for now, it'll support dual Z motors (using the Z_DUAL_STEPPER_DRIVERS option in config_adv.h) so will do for the moment. In time I'm thinking Smoothie maybe, or a vanilla RAMPS setup.
