    Robo 3d not so great

    I know there will be some people that like their robo 3d. Most people may be from the robo 3d forum where one of my friends on the forum tells me that the people on that forum are working for robo3d and try to keep people from saying bad things about their printer. I for one have had my post taken off when I talked about problems with my printer. So you may have better luck with this poorly designed printer then I have had and that is great. I know 3 people including me that have not had a good experence with the robo 3d. For me I'd say to stay away from it.

    Well I hope that this forum can be a great outlet for consumers to post about their 3D printers without being censored.
    That is the problem with a lot of manufacturer forums, they have a strong motivation to censor negative posts, that will never be a problem here.

      I'm sorry if it ended up as a bad investment. What are you going to do with the printer? Does it make usable parts at all or is it just spewing plastic? Maybe we can help get the printer to be in at least a usable shape for you.

        I did get the printer in working order after about 2 months of repairs. Just about everything was wrong with it. All the rods that the bearings ride on were 5/16" diameter and not 8mm like they should be. I changed those to nice hardened and ground 8mm rods. Then the z axis screws and motor couplers were running out so bad the head would wobble all over the place making prints unusable. I replaced the couplers with ones I made on a lathe. Then I replaced the z axis threaded rods with 8mm x 1.25 rods. The threaded rods for the z axis were 5/16-18 rods and I could have made better rods by hand. Then the head went bad so I replaced it with an E3D hot end. Then the bed wobbled all over the place so I replaced the drawer slides that it rode on with new ones I got from robo3d.

        After all that I tried to be nice about helping others understand how to fix their robo3d on the robo3d forum and got bashed to the point than I just couldn't stand having one of their products in my house. Some of my post were deleted and they were nothing more than talking about how to fix some problems with this printer. Never did I say bad things about it. After all that I still had to make a number of other fixes to make it print good enough to feel ok about selling it to someone. So I did that and I sold it.

        The robo3d has a ramps 1.4 and stepper motors that are good. The case is also made nicely. The heated bed heats up nicely. I guess those things are pluses.

          That is sad, but I hope that the person you sold it to understand printers enough to deal with any issues it may have. Are you planning on getting another printer, or do you own another printer?

            Bret4 at these forums, no one will be allowed to bash other members here or they will be escorted out the door and there accounts will be stoped. With that being said thank you for sharing and letting us know what we could be in for when purchasing this 3D printer.

              I don't believe he was bashing anyone. I mean sure, be nice and such, but he's documenting you're perspective on a product. Documenting his experience with customer service is part of that. Besides, even if he was bashing the product, I seem to be missing where he was bashing another user of this forum.

                It's ok, he didn't mean I was bashing anyone. He ment that what I went through on the robo3d forum wouldn't be tolerated here. That is good to know. Everyone has their own opinion and this sounds like a great forum to express it. But not letting people that like to start trouble for some kind of sick fun stay on these forums is the best policy. Being able to come to a place where you can get honest help will go a long way in making this forum popular.

                On selling to someone than can fix a printer subject. The guy that bought my printer seemed to know enough to fix things himself. But I let him know that I am always there to help with his questions if he needs it. So far he has been doing good with it. But for me it just couldn't be made to produce high enough quality prints to my liking.

                My opinion is that for what you pay of it there a lot of other printers that work better for the money.

                Anyhow I do not want my problem with this printer to become a complaint department on the forum. I just wanted to share my opinion. If others own a robo and post here I'll see if my experience can be of any help in getting their robo working better. That is the least I can do to help others in need.

                  I have to say my experience has been completely different. I'll preface by saying my unit is quite new so has had many improvements made by the factory, a quality I find as a great plus. They are listening to their owners and responding accordingly. All new parts are factory available do the upgrade path is simple and inexpensive. Having said this, and even though I made a first print out of the box within fifteen minutes, there are still a number of things that you can print to make the printer better and more accurate. Isn't this the spirit in which the ReRap movement was founded? Plus I enjoy seeing the fruits of my labour coming right out of my printer. Now, if you're doing medical prototyping, perhaps you've picked the wrong printer but, come on people, this is an $800.00 machine. At that price point it is sheer perfection and I would buy another one in a minute. It's easy to learn and easy to use just the way it is or, like me, you can print your way to upgrade this to a super accurate machine for almost zero cost. If the R2 is anywhere as good it will be the only unit I'd consider. BTW I do not work for the company, I bought my unit from B&H camera and had it delivered in two days free to Canada. I'm not an engineer or designer but a retired helpdesk person. If I can use it you can too. Enough said.

                    Such is the nature of most all crowd funded products. Much has been learned about the printer. There are some simple upgrades that have been developed by users that truly raise the printer to high quality and have increased it's reliability to the point it far out performs the "big name" boys. Word is, the company has adopted them and soon will be offering a revised machine that is solid.
                    But despite the company's claims, do not expect to run ABS. It's a rockin PLA printer but, that's it. Of course, that goes for most all of the consumer machines.

                    The company has a site with forum and chat room - many there can advise how to do the mods. Be sure though to get input from more than one person, the site is dominated by a guy with a monster ego and myopic experience. He'll be happy to tell you what he thinks is gospel but seek a broader experience base and you'll have success.

                      I have the ROBO 3D R1 and it is a solid machine. I have not had any issues with it all. I am very happy for the money and the prints I am getting.

                          Hello,
                          I have had my Robo 3D for three years and have never had any trouble with it after I was told to use a G code to print instead of a STL file. I move it twice a year between Washington and Arizona and have never had a problem until this year and the moving caused something to happen. Instead of self leveling, it moves up about an inch instead of going down to the glass and ends up six inches above the glass to print. I contacted Robo and they told me what to do and it stopped that problem. Now instead of self leveling, it goes to the glass and if I didn't press emergency stop, it would go right down through the glass bed and probably break it. Has anyone else had this problem? Robo is still trying to help me fix it but as yet a solution hasn't been found. Anyone out there have an answer? Thank you, Marvin
