Make a TAZ 5 with a TAZ 5 ?

Recently purchased our 1st 3D printer at work ( a TAZ 5 ) and been using it a lot for prototype work.

I would really like to build one for myself ( home use ) but cant afford to drop $3k on what is essentially a "toy" for me..

The KITTAZ option doesn't seem to be available anymore ???

I can handle the mechanical aspects and sourcing of frame nuts bolts motors belts printed parts etc.. ( work will allow me to run off a set of printed parts for myself ) although it will be some time before I can sneak them all in around legitimate work..

I'm left with the electronics cables & "firmware" bit which honestly I don't know much if anything about.. I haven't opened up the controller box yet to have a look at what's inside there..

Is there a "kit" available or can I order all that is required from Lulzbot themselves ?

I've seen the Rambo board and cables on the site for $220 what else would I need ?

Is there a less pricy way to do it ?

I can handle reading wiring diagrams and some basic soldering / wiring but soldering components onto a printed circuit board is probably pushing my skillset pretty hard..

I'd really appreciate any advice or direction to similar forum questions / answers ( I did try searching but had little success )

Thanks,

SS

Well I do not think LB sells all the required cables, so you probably will have to source the ones you can not find or build yourself. The only board I have seen is the RAMBo and all the parts are already soldered on it.

If you look in the user gallery there is pics of a Lulzbot clone that a user made. He says that the cost was around 1k if you have a 3d printer to print the parts. I would love to make one myself one day.I have had my Taz 5 since February and I actually made a Prusa I3 myself. I made it from scratch and even printed the frame to try to keep the cost low. I probably spent about $300 total with electronics and vitamins. If you build yourself it teaches you a lot about the printer and the firmware. Most of the how to's on the Marlin firmware can be found online. I would check out reprap.org for starters. Hope this helps and good luck.

You can get the exact Rambo board used in the tax from lulzbot or direct from ultimaker. You want a "full graphics LCD" for the display. You can get the LCD case and the taz 4 electronics box from the lulzbot store. The ultimaker board comes with the endstops and some wire. You will want 5 motors from the lulzbot store. The hotend you can get from amazon.com. make sure the hotend is the AO edition hexagon as they are different. The heated bed you will also want to source from lulzbot. Any standard 24 volt 3d printer power supply should work. ebay has those.

Once you have all the electronics wired and connected (electrical connectors from digikey.com ) you just load the stock taz firmware and then tune your extrude steps accordingly.

It may be cheaper to buy a used taz 3 or 4 and upgrade that to a 5.

Thanks for the speedy input guys, really appreciated !

So is the "Rambo" board advertised on the Lulzbot website the only electronics board I would need ? so that, with the motors, connectors, wiring and micro switches ( sourced elsewhere ) would complete the electrical aspect hardware wise ? the wiring isn't too complex and I could buzz the works TAZ to copy the layout and connectors configs, its a lot of work for a self confessed electrical amateur but I'd be willing to give it a go...

Do I need any extra hardware for the firmware install like cables, eprom flashers or anything else unusual ? ( I take it this can be done from a PC ? )

Wish I could find a cheap used or damaged TAZ but I haven't seen anything advertise for sale anywhere.....

I'm almost tempted to just accept that I may be better off buying a Chinese cheap diy kit for my home based amusements and just use the works TAZ for anything more "serious" I may need to do

On that subject has anyone ever tried one of the $400 "delta" type kits on Eb-y, they look like fun but I suspect would be pretty useless ? I also like the look of the rostock v2 but dropping $1k in one chunk isn't really an option

Thanks

The LCD board is the only other circuit board aside from the Rambo board itself, and it is optional. You connect to it with a standard USB device cable. Here is the full step by step TAZ 5 build instructions that show all components https://ohai-kit.alephobjects.com/group ... 8cca5d62c/ Don't forget the power supply and the bed and hot end too. Here's the board with the microswitches https://ultimachine.com/content/rambo-13
All the part files, part number and quantity lists with sources, etc. are located in here: http://download.lulzbot.com/TAZ/5.0/

Delta printers are an interesting project. They make very tall skinny things very well. I've not built one, but I am told they can be a bit more difficult to dial in initially. Any printer you can put together can be made to be very useful and accurate, it's just a matter of how much time and effort you want to put into it.

Thanks Piercet great info in those links ! im gonna do some serious reading before I commit but I think I can probably handle it with that information, it does look like my soldering skills are going to need some improvement before I take on the electronics though :lol:

Im going to go ahead and produce the printed parts and start sourcing the mechanical purchase parts by the time I've done all that I should have enough cash to buy the board motors etc..

Thanks again guys for all your guidance and no doubt ill be back soon asking for more help

You're welcome!

Most of the electronics used in the stock TAZ use crimp fittings. You shouldn't really have to soldier anything for that build at all. I personally find pin crimping to be just as difficult as complex soldering, but thats just me. The only soldering I can think of that you might run into would be making one of the endstop wires longer.

Hi been making a bit of progress and have most of the mechanical parts printed & built up, I cant find a model of the "x end plate" part no pp-fp0031 I think..... I realize these should be machined out of aluminum but I want to have a go with printed parts as much as possible, if they break down the road so be it.. any Idea where I could find this model ?

Thanks
SS
