Mine arrived last week but it was 'spirited away' to be wrapped in Xmas paper

 

aaaaaannnnnddddd... i have printing  Dave, you're gonna love this board. it's whisper quiet...

Does it use more than 16x microstepping?

up to 256

finally got x, y and z homing working... oh my (insert non-existent deity of choice) this is quiet compared to the other board...

it'll give you a chance to do a bit of reading... this thing is definitely not plug-and-play kit  

my duet wifi arrived yesterday... still fitting connectors lol

curse having to go to work.

tis a bit disconcerting using putty as a terminal to send gcode to activate the webserver, but to say the interface is comprehensive is somewhat of an understatement.

now, back to soldering

But I'm thinking "If it ain't broke, don't fix it"   That part of my printers gives no problems.  Much more critical is the hardware.

mine IS broke though 

have you tried the neodymium magnets out of an old harddrive?

should be a lot more future-proof than the atmega range (which to be honest is getting very long in the tooth now being only 8 bit) better drivers, better interface, better firmware etc etc etc...

At some point, yes. I won't get my paws on it till Christmas Day so you will have to be patient

 

 

well, i just pulled the trigger on one so it should be here in a day or 2... and now to play with the big boys

Santa's bringing me one of these for Christmas (don't ask me how I know ) - Can't wait to go 32-bit and quieter stepper drivers etc. Will have to wait till Christmas to open it though .

hope we get a review of this... my extruder driver just turned it's toes up and of course being a cheapo chinese affair, the whole mobo is now useless :/

If you're using 3 lead screws for the bed then surely autolevelling won't be an issue once it's all set up. can't speak for the coreXY design, but since i rebuilt my A8 using 2040, i've been using 15mm spacers between the bed and h-plate and haven't had to relevel the bed for going on 6 weeks now.

must be some weight to the print bed for it to do that...  :|

did you get chance to upload those files at all?

good one...

i took a slightly different approach... i've got 3 8mm grubscrews at 120 degrees in each bracket. just need to find some 1mmx10mm wide spring steel to make compression rings for the grubscrews to act on. attaches directly to my tube (when i can be bothered drilling it). the camera end has practically no movement and the front allows 1, maybe 2 degrees of adjustment. can't see me needing any more than that.

Files are available of course. There's no reason to keep them hidden from other ATM-friends...

nice one  where from? google has a thingiverse link but it gives a 404 error

are the files available or is this a private project?

awesome

what size printer hotbed is needed? dould 220x220 be big enough?

Looking very good there Dave...

Are you using the eccentric bolts on the wheels to remove any slop btw? if so, how are the printed parts holding up?

I've decided on this one https://www.thingiverse.com/thing:2254103 HyperCube Evolution... it's gonna be a biggie lol.

Just got to find a source for 30x30mm extrusion as ooznest don't seem to supply it :/

I've just switched to PET-G and started printing the parts for the hypercube. Going to be a 'from scratch' build as i plan on using a Duet3D controller... bit of a step up from 8bit to 32bit

Had a real laugh (not) when i switched to PET-G... thought i'd get some nice translucent red by real filament... i think they mix some sort of molecular welding glue in with the filament as the first print pulled a lump of glass out of my glass bed, and the second print pulled the surface of my buildtak 

It also strings like crazy regardless of which settings i use and actually comes out more carrot colour than red. Avod Real Filament if you can

Anyway, i ditched anything from Real Filament and went with my usual brand by Prima... their PrimaSelect PET-G prints wonderfully and pops off the glass just like their PLA.

Luckily, i just got a bonus at work so as soon as i source the 30x30 extrusion, i'll be decimating my bonus lol

watched this seriesof vids last night... i'm soooo tempted to do one

https://www.thingiverse.com/thing:1752766

wish i could afford that sort of gear... no buyers for my spare internal organs so far lol

So after quite a few emails to the excellent Dave at Rowan Engineering, i can get 12T and 47T pulleys to fit, although the 47T will have to be sleeved to 6mm. What i don't know though, is the calculations required to see if i'll be getting the same ratios... my Vixen GP has 144 tooth gears on the RA and Dec, which i believe are the same as an EQ5 and it's currently using an EQ5 upgrade motors and gears.

Anyone got any links to how the calculations work so i can work out if eqmod needs custom settings?

"Just to say to everyone that getting the polar alignment error down to a few seconds of arc is really unnecessary (although fun...)!"

well it's your fault for giving us the tools to do exactly that

Having watched the polemaster videos, the one thing that really impressed me was that there was no 'click this or that star right in the middle'... sharpcap is far more intuitive to use.

Ok, i'm having an out-of-body moment with this one and just looking for opinions...

I've been looking at various mounts and their belt mods, yes the rowan mod, and after a quick google, it appears that people on cloudy nights have done belt mods for Vixen GP mounts (although there is no specific details listed)

Aaaaaanyway... it got me thinking that as i already replaced the original stepper motors on my GP with a synscan EQ5 upgrade, would it be feasible to replace the gears provided with the synscan kit with a good quality belt drive?

Just a thought as:

a. i want to tinker

b. i'm broke so no mount replacement

c. i adore my Vixen GP

finally managed to get my scope out for a play tonight... fired up sharpcap and (although i've never used it before) within minutes had the best polar alignment i've EVER had...

Robin, you're a goddamn hero

wasn't intending to try any AP as, with my personal situation meaning it's been 2 years since i did any, i'm rusty as hell, but fired off a few subs anyway. no guiding whatsoever, balance was questionable and the dew was starting to form at -3 degrees at 2am this morning but what the hell... for totally unguided, i'm really impressed with sharpcaps abilities

even managed a small amount of detail my new favourite, Barnards Merope Nebula lol

just a quick stretch and not much else. got a bit of distortion in star images but thats probably down to having to clean the mirror and it needing a bit more poking and prodding to get into shape, but all the software updates/new stuff apart from phd2 (which totally refused to calibrate and failed every time on the clearing backlash phase) worked flawlessly.
