Large corexy mechanical kit options

Back on point,
I've spoken to the Rat Rig guy, and he's been right on it with the responses and advice.
I did mention the lead time, and he said they got behind a little at one stage, but they were right up on it now.
For me the decision is to go with their 400x400x400 V slot model with the 3rd Z screw option, just need the money which will likely push the order date out to June.
I've really had enough of Z screws I must admit...I'll look at the belt option harder in the meantime.

Hi all.
Looks like my birthday's coming early, as I've squirreled away enough money to pull the trigger on a V-core kit.
I've been in touch with them with a million questions, and I must say the responses have been excellent, even including a call direct to my mobile in Australia from Portugal last night.
I was going to go with the 500x500x500 model, as it only costs a little more, but funnily enough the Keenovo mats almost double in price from 400 to 500mm, and it seems build surface options become much more limited as well.
They have offered that if I buy the 400mm model but pay the 500mm price (only about 20 euro more), they will extend the Z height to 600mm. I'm wondering if that will be worthwhile, or should I just go with the 400mm all round size?
I'm going with the triple Z axis leadscrew option, but without the motors as I plan to run a single belt/motor. I do wonder about their Z setup as they run 4 upright V slot channels with rollers, which may defeat the purpose of the triple leadscrews, but I'll look at that when the time comes. I'm still open to the possibility of a belt driven Z axis.
It comes with the 400mm build plate, but it's only 4mm thick. If it's flat that will be fine, if not I'll go with 10mm cast ally precision plate.
I've got a ton of gear here including a Duet wifi/paneldue, E3D V6, Meanwell supply, plus/wire...all sorts of goodies.
It'll probably take a long time until it's done, but I'm quite excited to get started. Also glad I didn't go the Tronxy route, as it seems they are a pile of junk for almost the same money. Cheers to those who advised against it.

@Corexy congrats and happy birthday! An extra 200 mm in Z for 20 bucks or so, sounds like a no brainer if you can physically accommodate that height. Ref the linear guides, you only need 2 - maybe 3 depending on how they are arranged. The more you have, the more difficult it is to get them all aligned (although Vslot and wheels are a little more forgiving in this respect).

Cheers Ian,
Not literally my birthday, I just managed to accumulate the funds a little earlier. This might mean that I can get that Bondtech BMG I need for this project as a pressy....
That's how I'm thinking...they've got 4 vslot z rails and 3 leadscrews. I'm of the mind to make it a vslot rail with each leadscrew, possibly with the delrin backlash nut mounted mounted on the actual roller carriage plate.
I'm also considering a water jet cut all floor to mount the bearings/pulleys for belt driven z axis screws/pulleys. IF I don't go with a Digitaldentist style reduction gear belt drive for the Z.
But I won't get ahead of myself, as Ratrig seems to have gotten by just fine without my advice/assistance/opinions so far. I'll have a look at the thing first and take it from there.
As for accommodating this thing, I think it's own small table or roller trolley will be the way to go. It certainly won't fit on the workbench.
Cheers all.
**Order placed. Let's see how they go.
-
@Corexy Yeah, I guessed that it was either a "metaphorical birthday", or an "official birthday" like the queen has.

Ha ha!
All my birthdays are metaphorical in a way, and it's hard to be happy on a day when you've just added another number to 5__.
I'm tipping the Queen gets more cards and a nicer cake too!
-
@Corexy nah, 50 something is nothing. I find it scary that in 3 more years, I'll be adding numbers to 7. I'm planning on hitting 100 - then the queen (or king) will be sending me a card.

That's one way to get her attention I guess?

Just in time for the Duet 8.

Little update...
It's been almost 3 weeks since placing the order, not dispatched yet.
I must say the communication has slowed/stopped (they answered a couple of technical questions since, but 2 emails asking about dispatch have been ignored so far) since payment was made.
I have no doubt it'll come, but I'm tipping there's a sales department that makes promises (like 1-2 weeks lead time) and signs them up, then flicks the order and his promises across to the production department. Not the first time I've seen that...
It doesn't bother me too badly as it's a long term project, but if it were to stretch out to 6 weeks I'll go for a refund. Hope it doesn't come to that.
-
@Corexy Hang on in there. It'll come eventually. Looking back through this thread, I mentioned on 24th Feb that other people had said delivery was a pain time wise, but otherwise fine. Covid my be causing problems too. But I agree, it would be good if they kept you updated.
-
Orders sometimes take a lot of time. Ratrig employees are active on the Facebook page (sorry), so they're not gone dark.
-
I'm certainly not worried about getting ripped off or anything like that. I don't even mind waiting a month or so. And yes, I did note it was a regular occurrence with them.
I guess in my opinion, saying a week or two then just stopping replying after the order is taken is just a little bit of a bad look. I actually asked him specifically about lead time and delays with other orders when he rang, and he said they'd had delays in the past but it would ship in about a week. I said 2 weeks lead time would be fine.
I am a particularly grumpy hater of FB and Google (I'm a parent of teenagers), so you will NEVER see me on there.
It's certainly not as bad as a fake tracking number from Banggood or Aliexpress, which never ever works lol.
-
So in the interests of honesty and transparency,
A nice young lady from Ratrig contacted me just now, and explained that they had local holidays and a huge backlog of emails, and that my order was shipping today.
I'm not fussed about how long it takes, as long as they communicate it, so as far as I'm concerned my experience is still all good.
I am keen to see this kit!
-
@Corexy That was nice of them - although no less than one should expect.
-
Hey! The tracking number works!
That's the first big plus over buying from China...I swear they just close their eyes and tap randomly at the keyboard when they enter a tracking number over there.

That's not my experience with Aliexpress purchases.

That's funny....they've been the absolute WORST for me, most times. Banggood is about 50/50 in my experience.
I guess it's all on the experience you have personally. Could also be about what part of the world you're in too.
-
@Corexy, my experience is that the tracking numbers Aliexpress vendors provide eventually progress through the shipping stages such that they are real numbers.
-
@zapta I bought something that never turned up. I was told it had been delivered. The tracking number never worked. I asked the vendor to contact the courier and get them to say the address of where it had been delivered and who signed for it. Eventually, they admitted that something had gone wrong with the system and the courier company had wrongfully said it had been delivered. After a long drawn out battle, I eventually got a refund.
