Ok, unfortunately they've cancelled my order due to lack of stock.
Thanks, that's larger. But I'll work something out.

That's a shame but I see they have got another item number for the RepRapPro 3d printer with green printed parts. RS stock number 795-2333, back order for despatch 20/12/2013.

My order for the original red printer is still showing as due for dispatch 18th December, so fingers crossed I'll have it to play with for Christmas. I ordered late thursday afternoon, when did you place your order?]]> tim_h Ormerod Mon, 16 Dec 2013 09:31:42 -0500 https://reprap.org/forum/read.php?340,275039,280436#msg-280436 Re: RepRapPro Ormerod https://reprap.org/forum/read.php?340,275039,280436#msg-280436 Thanks, that's larger.

Thanks. That's interesting because on rs they have stated 500x460x410.

So I'd need a little less space then. That's excellent news.

I just measured mine (ignoring the power supply).

Allowing for leads that come out of the sides, clips and the feed tube at the top, I make the enclosed size approx:
width Y 470mm, depth X 420mm, height Z 480mm

So RS figures give a bit of working space 30mm or so around it but I think their height figures ignore the tube at max Z height so are short.]]> Treth Ormerod Mon, 16 Dec 2013 04:01:19 -0500 https://reprap.org/forum/read.php?340,275039,280287#msg-280287 Re: RepRapPro Ormerod https://reprap.org/forum/read.php?340,275039,280287#msg-280287

I just did some prototyping for a customer and whilst the parts I made are to a high standard of finish, they are still making their minds up over design and I could have printed test parts in a few hours than manually machine prototypes over a few days that are now not to be used. Not a problem for me as I still get paid, but it ramps the customers R&D bill up.

early days for me yet, but I managed to print some pieces today, I've uploaded a blurry video to youtube [youtu.be] (not sure why the link is youtu dot be, but it works) of it printing test pieces. I had the head a little high and the temperatures a little low to get good adhesion on one of the three parts that should have printed, and I stripped this as it printed (it IS my first machine :P ) I then printed a couple of smaller parts (coathook and a bar fastener), the photos of which I'll upload tomorrow if I can get my mac to recognise the camera's SD card.

The calibration test pieces look a bit ropey, but they used minimal infill I think so reducing material wastage - and I didn't have the temperatures right. the finish on the coathook is pretty acceptable for a prototype, not so for a one-off production item, but as I say it's early days for me.

I bought this machine for similar reasons to those you have maybe - for prototyping, and also potentially one-off or short-run pieces that are beyond my manual lathe and mill (and skill) to machine (mainly enclosures and complex small items) - the printed pieces in the kit itself are definitely of the quality I aspire to, though there's no guarantee they were printed on Ormerods - maybe Ian/droftarts could comment with his official hat on...

RepRapPro tech support]]> droftarts Ormerod Thu, 12 Dec 2013 14:35:11 -0500 https://reprap.org/forum/read.php?340,275039,278904#msg-278904 Re: RepRapPro Ormerod https://reprap.org/forum/read.php?340,275039,278904#msg-278904
indeed nuances are easy to miss in text-only communication:)

On with the thread - this is my first jump into reprap (I bought one of the `first batch of Ormerods from RS), so I can't throw much comparative light on the Ormerod design versus other machines, but I can confirm that it is well designed from a build point of view (especially with the updated instructions now available).

Calibration wise, the axis movements are accurate using the pre-set steps per mm - using a hand-held digital caliper as a "dro" I get 99.9-100.2mm travel on each axis (x,y,z) for a 100mm movement (the uncertainty in measurement is because of the way the measurement was taken I think, I'll attach a gauge properly to measure for further calibration when I get to use the machine "in anger". The extruder calibration is simple (the preset seems to overfeed, but the value in the current config file corrects that, but manual calibration is likely to be necessary - simple though as I said), movement in the filament is very reproducible calibrated or not.

Levelling the bed is pretty simple (but a little fiddly), the automatic plane transformation that compensates for residual slants seems to work very well, and will be a very useful feature. The z axis is homed using an IR proximity sensor - by design this requires use of aluminium tape in four spots on the bed, but actually I found that by aligning the sensor while checking its readout, I get strong signals from the kaptan tape alone (I haven't yet done any statistical analyis to see how reproducible the signal is, but the bed compensation works fine for me without aluminium reflectors).

Initially I positioned the Z axis pillar in the wrong place so X homing resulted in crashes for me, the printer is robust enough to withstand these! It appears that the same IR probe is used to detect X home (by reflection from a plastic tab on the Z pillar), and now that the head can reach this tab, it homes correctly :) Y axis homing is relative to a microswitch, this also works correctly.

My machine seems to have a faulty duet board, which I understand is to be replaced, so I haven't printed more than the first few layers of the test pieces, so haven't carried out the orthogonality correction (though I presume this will work as well as the related bed compensation). The quality of these layers is surprisingly good since I'm at the bottom of a learning curve in using 3D printing (solid and smooth bottom layer, good in-fill and smooth outline), so I have high hopes.]]> rayhicks Ormerod Thu, 12 Dec 2013 04:55:50 -0500 https://reprap.org/forum/read.php?340,275039,278785#msg-278785 Re: RepRapPro Ormerod https://reprap.org/forum/read.php?340,275039,278785#msg-278785

Maybe I misunderstood but I don't know if anyone was really suggesting the problem was with what droftarts/Ian did in this thread. The issue is that DeuxVis and possibly others never realised before that droftarts worked for RepRapPro because it's not always mentioned in the post he makes (which as has been said is ultimately up to him but there are good reasons why many feel it's a good idea). The fact that droftarts mentioned it here is probably what started the whole thing as people realised from what was said here that he works for RepRapPro.

I've been on the forum longer than I have worked for RepRapPro (joined forum April 2011, worked at RRP since December 2012), so there is a lot of my older posts that don't have a RepRapPro signature (I don't use the automatic sig, I write it in). If I'm helping people with RepRapPro machines, I say who I am, so they can take my advice seriously. If I'm at work and using the RepRapPro username, it's always about work, and I always use my signature - I wouldn't use it for commenting on other things. Other employees of RepRapPro have used the username in the past, but make it clear who they are when they post. If I'm helping someone who doesn't have one of RepRapPro's printers, or making a comment about something else, I use the droftarts account, and may or may not use my signature, depending on what I'm commenting on. If critiqued someone else's printer, I would say I work for RRP, but not put my signature in, so it's not an official RRP thing. My post earlier in this thread was just to offer some clarity on the questions in the thread, but does have my own opinion, so I didn't want it to carry the weight of an 'official' notification from RRP, though I appreciate now I should have said I actually work for RRP. I can't seem to edit that post now, probably because it has moved in the forum.

I think this is a sensible use of usernames and signatures, allowing for a split between work and opinion, whilst maintaining a consistent online persona. Sorry if it confuses anyone; it's not my intention to mislead. Let's move on. If an admin needs me to change my use of usernames, please PM me.

Anyway to get this thread back on topic, what are people's early thoughts about the Ormerod vs other options in terms of design and considering the cost. I'm particularly think of aspects other than reproducibility. Stuff such as ease of assembly, risk of stuff going wrong and how easy it may be to diagnose or fix, default capabilities, upgradibility (beyond the planned 3 extruder option). It does seem to me it would be better in at least the first 2 compared to the Mendel Mono/Tricolour (obvious comparison as RRP's most similar other printer) or other Mendels. On the other hand there are other stuff which share some characteristics which have been mentioned, I admit I don't know that much about these although some of them seem a bit expensive compared to the Ormerod.]]> Nil Einne Ormerod Wed, 11 Dec 2013 12:38:07 -0500 https://reprap.org/forum/read.php?340,275039,278600#msg-278600 Re: RepRapPro Ormerod https://reprap.org/forum/read.php?340,275039,278600#msg-278600

@DeuxVis - I was expressing my own opinion, not that of RepRapPro, so I left off the usual signature. I'm not a spokesman for the company, and I'm not trying to sell product. If I put my work signature on a post that expresses my opinion, it qualifies it as at least semi-official, which I'd prefer to avoid. I appreciate I post from a couple of different accounts, and generally I just offer support advice, and put the signature on so people know they can trust what I say, but does that mean I can't have my own opinion any more? I suppose it's a fine line.
I don't think there's anything wrong with expressing a personal opinion but when you work for a company, you obviously have a strong COI. This doesn't mean you're always going to agree with what your company does or defend it or recommend it to the detriment of others but it does mean it's rather difficult to be unbiased. Of course we all have our biases for various reasons but the potential bias coming from having such a strong COI as working for a company who's products and competitors* you are discussing, is generally taken as the sort of thing which should be declared as part of good forum etiquette (or in many other area of life). That way people can take this information on board when reading your post.

I think most here understand the need for clarity between the cases when you're partially representing the company you work for like when offering support, and for cases when you're not representing them at all, but instead simply mentioning your own views.

The way people often deal with the later is by including something like: "Although I work for company X, my views are my own" in their signature. Beyond being good forum etiquette, it's also often a good idea for your employer as otherwise people know who you work for could mistakingly think you are representing them when you are not. Then you can exclude this and instead sign off as RepRap tech support as you do now in cases where you're doing that. If you want a generic signature to include in all messages you can tailor it in some way to cover both. (The alternative is to have two accounts presuming this is allowed under forum policy.)

*Even thought we're generally discussing open source products, stuff produced by others in the open source movement are in some way still ultimately competing products.]]> Nil Einne Ormerod Mon, 09 Dec 2013 23:50:54 -0500 https://reprap.org/forum/read.php?340,275039,277875#msg-277875 Re: RepRapPro Ormerod https://reprap.org/forum/read.php?340,275039,277875#msg-277875

Is it self-replictating?

I would say no, or less than your other machines. Also the new electronics make it even harder for most to make it from scratch.

Also its no a new design. Printrbot simple and the newest qubd machine cam first.

I would also assume most RS customers wouldnt like incomplete or wrong instructions.

1. Is it self-replictating?
I think so. Sure, there are more laser cut parts, but the smaller ones could easily be printed instead. It just makes sense to use laser cut material for large, flat areas. There has always been a certain amount of lasercut parts, dating back to the Sells Mendel. You could change the design a little to remove them, or make them out of simple drilled material. The X axis is a bit trickier, but it could be replicated with hand tools. Other printer designs are certainly less self-replicatable, or indeed have no printed parts. As with all printers, there are still a few parts, such as the electronics, heatbed PCB, Z probe electronics, hot end etc, that are harder to replicate, but these could be swapped out for regular endstops, other electronics, etc; the designs have been open-sourced, and we prototyped the proximity sensor and ATX power distribution board in-house, using a CNC mill. Perhaps the most difficult thing, availability-wise, is the use of extrusion, but the stiffness this provides, the reduction in fasteners and other hardware, the ease of build, all far outweigh any difficulty sourcing it. 12mm bearings and smooth rod are the same price, or cheaper, than 8mm.

We've worked hard to bring something new to the community, another style of printer, and I feel it gives people more options; it's up to others to personalise the design, take it further, or in a different direction, if they wish - though we won't be standing still, either. That's the beauty of machine evolution. Though I think we're leaving it up to lovers of imperial dimensions to come up with their own version!

2. Crowd-sourcing printing
We've done this before, with our Mendel kits. It's tricky keeping control of quality, though. I had experience of this before RRP, with the Thames Valley RepRap User Group (TVRRUG), who have printed about 75 Prusa Mendel i2 variants. Again, quality across a number of machines, calibrated by different people, is the issue. The Ormerod parts do need a well-tuned printer for good fit. So, we're keeping production in house for the moment.

3. Multi head printing
The combination of the Duet and daughterboard offers 8 axes, and support for 5 extruders. Each extruder needs temperature control, which the Duet and daughterboard have. The pairing of two Melzis can only support three extruders, because, despite the extra axes, there are only two temperature inputs on each board. Though you could add an extra board to add more temperature circuits, I suppose. The Arduino processor on the second Melzi does virtually nothing - it just sends temperatures and receives step commands to and from the master. The nice thing is that it does it down just 4 wires connecting the master and slave; the Duet uses a parallel connector.

4. Duet firmware features being backward compatible
The Duet uses an entirely new firmware. I have no idea if this can be back-ported - I'm not a progammer. I think the proximity sensor could be written for Marlin; the bed compensation code is in Marlin already, as others have already shown.

can we still call this self-replicating ??

Only partially, and as far I can tell replicatability percentage is regressing from reprappro's previous designs.
This is quite unavoidable when you aim for "classical" mass production.

On the other hand if they had gone a more innovative mass production way, like say "crowd printing" as Emmanuel Gilloz - and maybe others I did not hear about - experienced with, they would probably have had a real harder time convincing RS to sell that model.

You're so right!

I was just a little embarassed, when it's the initiator of this all new industry ( personal 3d printers) talking so much about replicating, and see a "mass production ... product". But i understand very well the reprap spirit is totally incompatible with money making :)

I just laugh thinking about RS distributing a crowd printed reprap.. lol]]> smartfriendz Ormerod Fri, 06 Dec 2013 18:40:55 -0500
