      Dear Sir/Madam,

      After several months with lots of test, we’re really tired of your 3D printer.

      We’re not going to try any more bad solutions.

      We’ve been testing everything you tell us, what we read in the fórums and our own experience. As we’ve told you before, we have almost 10 years of experience in 3D printing and we cant find a solution for your machine.

      We would like to report several issues regarding the toolhead of the printer, which unfortunately have prevented us from using it anymore.

      Problems like constant (2 or 3 per minute) "Toolhead bad connection", "Toolhead not connected" and "Printer cannot control toolhead temperature" errors arise when printing, even after installing the new USB type C cable and new circuit board you provided us, trying the rubberband and cableholder method (and also trying with various printed parts to try to prevent the connectors from wiggling), and activating the "smart task continuation".

      There were also other problems with the printer, such as the filament detector not working or the mini usb port on the base of the printer being broken an inaccesible, although fortunately they didn't prevented us from printing thanks to some workarounds, butthat was before toolhead malfunctions arose and rendered the printer unusable.

      We would like to know if there is something we can do to return the printer to operational state, or if there is any way in which you can help us.

      The printer serial number is FDxxxxxxxxxx.

      If everything keeps the same, we would like to give the 3d printer back to you and have a new one, because everything looks unproductive.

      Thanks in advance. Looking forward to hearing from you,

      @Quang Do, @Jarge Man:
      Go to and open a support ticket.
      Don't be afraid to. They don't respond quickly but the tickets don't get lost.
      The PayPal problems seems to be gone and the tax excess is refunded.

    3. Jorge Man on June 24, 2016

      @creator! Hey Flux, how are things going?? There are a few backers that are waiting to receive the tax refund. In an earlier update (8th May), you told us that we have to wait for your paypal account to be fixed. Almost 2 months have passed and we have no feedback about it... and no tax refund has happened...

      Please can you tell us, how is the refund process?? Thank you very much!

      @Guy Raz the engraver is the pen holder, the laser can be removed and then you can put a pen in there.

      @Leung Kwa Yat, Hi I had that noise issue, what it fix it on my end was the speed of the filament feeder, I have it now on 0.9 and now it works correctly. The problem with my printer is that the feeder was feeding the filament to quickly to the nozzle so I lowered and now it works correctly.
      I recommend that you visit the forum (, there are a lot of threads where user post this kind of problems and there are answers/solutions to these problems.

      Hi creators of FLUX Delta.
      I want to ask about your update # 12 (dec\12\2014) You told that you will absorb the difference between the customs duty & VAT and $100 if any.
      I wrote 3 times earlier to you here on Kisktarter & to your support team. I attached all customs clearence documents to my mails. But you keep silence almost for month.
      backers who recieved money for customs clearence (If any) please write how you do this! Thanks

      I'm curious on the status of Jim, I have a ticket with him that I would love to have it be resolved and I haven't heard from him in over 2 weeks. My printer was sent with corrupted software, I was sent a new micro USB and my Flux still isn't doing the proper breathing that it should be and the conversation was halted there. I've had this printer for over 2 months just sitting, I'd like to get some sort of clarity on the next step.

      Thank you,

      Hello Flux,

      I received my flux delta yesterday and was doing prints without any problems. But when I went to start up a file I wanted to print today I noticed that I received an error regarding the "Toolhead alignment" becoming out of place. So I go to look at the printer and notice that one of the "Diagonal Rod's" came out of the socket where it meets the tool head. This happened 7 times in a row with the rod coming out of the magnetic socket, is this a manufacturing error or just a bad magnetic socket? or short Diagonal rod? Also I am running the flux studio v0.3.0 and the tool head software that comes preloaded (not upgraded). Thanks!

    37. FLUX Technology LLC Creator on May 8, 2016

      I apologize for the slow RMA service for your case. Please read the detailed explanation in my message for you.

      Yours will be shipped soon. I believe it will arrive at your home earlier than the Maker Faire Bay Area! But still, looking forward to meeting you at our booth two weeks later. Please provide your feedback on FLUX Delta then! :D

      @John Harry Carter
      Hello, I believe there must be some misunderstanding. I didn't get your mail in my personal mailbox. I have replied to your message through Kickstarter mailbox. Please check.

      @David César
      First of all, I have to clarify three misunderstandings.
      (1) There was nothing wrong on our invoice. The money we got from this Kickstarter campaign belonged to our "US company" first. But after this campaign ended, all of our team members moved back to Taiwan to focus on the software development and product manufacturing. Therefore, the products were actually produced by our "Taiwan company" in Taiwan. According to the accounting and importing laws, the invoice should declare the value of this package provided by our "Taiwan company", imported by our "US company", but shipped to the individual Kickstarter backer. Which should be just different from the amount that the backer paid.
      (2) This inconsistency indeed confused some backers and customs. But again, it was not wrongly declared. All the shipped packages were attached with the complete shipping information. For most of the cases, the packages still passed the customs after some simple checks safe and sound. And even better was that it helped lots of backers to pay less for the taxes.
      (3) To be honest, the lack of conscience of the Brazilian customs is well-known for people experienced in global logistics. The package size of FLUX Delta is very big. Also, It is a valuable 3D printer. Paying crazily high taxes (another Brazilian backer even paid another 100%) was just inevitable for your case. Asking for fines was just a way of another form for the customs to earn extra money from you.

      I hope I have explained everything clearly enough above. But don't worry, promise is promise. We will still absorb all the additional fees higher than the $100 for you. Please wait around 1-2 weeks for us to restore the availability of our Paypal account. It was temporarily kept on-hold because of too frequent transactions recently.

      @Yap Way Lon
      We attached the item category and HS code with every package we shipped out.

      @Dan Smith
      This is creepy.... According to our record, yours has been sent out on 3/25. The tracking number also showed that it has successfully arrived at the assigned address. I have provided your tracking number through the Kickstarter message. Please check and let me know if there was something wrong...

      @creator Still have yet to get anything indicating when my printer will be shipped, it was supposed to be shipped on the 15th but that didn't happen. If I don't get some sort of email about the status by Monday night in asking for a refund.

    39. Yap Way Lon on May 6, 2016

      Guys, here is a list of import duty for 3D printers by country
      Mine arrived in customs 2 days ago and I managed to advise DHL to use the correct HS Code. In the end they quoted me abt USD 50 for Sales Tax as there is no import duty on 3D printers in my country. If you all want to avoid the unnecessary hassle of asking for refunds from FLux Team please refer to this and advise DHL accordingly as they have the tendency to use the wrong codes. @Flux Team, if you are reading this please try to include the HS Code into the shipment to save money for both parties.
      Thank you

    40. David César on May 6, 2016

      I was forced to pay a $178 fine, besides the 60% custom taxes, because FLUX Technology LLC filled the export form wrongly and declared $508 for the goods, instead of the $679 I've pay for my pledge. I sent an email with my complaint but haven't received an answer yet! The good deal has become expensive!

      Hey flux, I recieved a printer with a faulty motherboard firmware as advised by your staff. Had send a ticket and ask to provide shipping address for the sd card. Ever since, there have been no more updates or replies to any of my emails. That was weeks ago. Please update me? The flux had been sitting on my table unable to do anything for weeks. Will you then extend my warranty in this case?

    50. FLUX Technology LLC Creator on May 1, 2016

      Hello, backers!

      There is only one week left for us to fulfill all the Kickstarter orders. I will post a complete update wrapping up this project later next week! :D

      Before the final big update, I'd like to share several small updates here to clarify some misunderstandings first (Actually, many of them have been shared in this comment page before).
      (1) We haven't shipped packages to pre-order customers. Kickstarter backers are always our top priority.

      (2) The first step to prepare a backer's package is to provide shipping information for DHL. Then, the backer will get an automatically sent mail with the tracking number. However, it doesn't mean that the package will be shipped soon, but just means that the DHL document has been generated. The following wait time depends on the manufacturer, might be 1 day to even 2 weeks. Which is also why we couldn't 100% follow the shipping order we planned before to ship the packages. The reply time orders of backer surveys also influence the shipping orders.

      (3) Why we didn't make it to finish the shipping on 4/22 was because we found manufacturing defects of the printing toolheads in a small production batch two weeks ago. Then, we decided to pause the production and ask the manufacturer to rework all the printing toolheads, which caused a short schedule delay. We will share a detailed product design and manufacturing review in the following update next week as well.

      (4) Many backers still haven't replied to the backer surveys. Please make sure that you have filled out the backer survey and checked your mailbox to answer the further questions my colleague asked if any. After we ship the packages to all the rest backers who have provided complete shipping information next week, we will start shipping FLUX Deltas to pre-order customers.

      (5) Our customer service is still being kept overloaded...... We have refined our SOPs and recruited new employees, but there are still many messages and mails stayed unchecked and unanswered. I apologize for the long wait and appreciate your continued support. We are about to finish the shipping. We will try our best to answer all the unanswered questions no later than this weekend. If you think your question is very urgent and really needs my instant reply. Please just leave me a note through I'll try my best to reply to your mail in 24 hours. Thank you!
