Janome MB4

Hi, I presently have a Janome 350E embroidery machine and I am thinking of purchasing a Janome MB4 embroidery machine. Have you had any input regarding the MB4 from anyone who owns one? – Winnie C

Hi Winnie,

I own the MB 4. I love the ability of 4 threads and yet have 4 additional ready to go is awesome. It clips the threads between OBJECTS as well as the color changes. Thread breaks, the machine goes back to where it broke.

The hoops are larger and do not require splitting or multiple hooping.

I have had no problems with the machine as well.

    I just purchased a Janome MB-4 machine. I have a Brother Innovis 1500D which uses pes designs.
    I have pe design I believe 7.0 or 8.0. Am I going to be able to use all the designs I have that are pes format?

    Hi
    Anyone have a hat hoop? If so, the instructions on step 10 states; Pull the lower back edge of the cap toward the back of the hoop insert “base plate”, matching the center back seam of the hat with the V-groove. What do they mean by “base plate”? Anyone with the answer. Thank you,

    Hi. I purchased an MB4 and am anxiously awaiting it’s arrival. I am trying to find out if it will do 6×10 designs without splitting? Also, do I need to order an additional hoop to do the 6×10 or will the hoops coming with the machine suffice?

    I have a MB4 and have had problems when starting the machine. It is asking to make sure hands are clear to so that the carriage can move to the set position. It then makes a grinding noise does not move and asks to be powered down. Similar to the problem raised by Jill in October. Has anyone had a successful resolution to this issue. My repairer has looked at it twice so far.

    The problem of the needles breaking because they hit the face plate is very easy to fix. Look in the manual under needle changing and read about lowering the needle into the hole before tightning. That will solve your problem.
    I love my MB 4, I always use nets over the thread to prevent breakage.

    Hi, my MB4 also had the problem of grinding and powering down. My ealer/repairer did a home visit and repaired it for me in one visit. He was unsure of what to do so was on the phone to Janome who gave him advice. The problem was an electrical one. Not an electronic problem. I was told that it could be because something, like some threads, had ecome caught behind the arm as this causes the same sort of problem. I love my machine and have had no other problems. I use BuzzExplore to convert my designs to JEF. I have never had problems and would NOT recomend DST. There is a screen on the MB4 to format your memory stick, otherwise do as someone suggested, turnoff the machine, place the ‘stick in, turn on and it will format automatically for you. You need to then open the EMB file, on the ‘stick, and place your designs in that file on your computer first. Hope this helps.

    Hi Yvonne from Tasmania. I too live in Tas. The dealer who repaired my machine came from Devonport and he does home visits. He was very willing and helpful even though I did not buy my machine through him. Your problem sounded similar to mine.

    Doe anyone have any experience with snap hoops, magna hoops or similar for the MB4?

    I have heard that it is possible to hook my MB4 directly to my computer. Is this true? What type of cable is required? Is additional software required? No instruction manual to help me with this. Thanks so much!

    We are having a lot of problems with our MB-4 locking. It seems to start with tension issues (looping) and we noticed that our bobbin is not working properly. We stitched an entire design (which looked horrible) and realized after that it did it without the use of the bobbin. Finally by chance we got the bobbin to catch, and it stitched beautifully. The next item went right back to looping and no use of the bobbin. It then sucked in the top thread and we had a huge wad stuck in the casing. There are quite a few threads still stuck behind the casing, which has happened before and we have been able to get most of them out. There has to be some reason why this keeps happening! Now our machine is locked, which I am assuming it is because of all I the debris that we can’t get to. Does anyone have any idea what the problem could be with our machine? I assume all of our issues are related in some way. I am so frustrated. The machine is only 7 months old, and as much as I love it when it is working properly it has been nothing but a headache for over a month now. I find myself nervous to use it because I feel like I can’t trust it! Any help is greatly appreciated.

    Hi I am considering buying the MB4. I would appreciate any help in making my decision. What I really need to know is what is the largest area I can embroider with it? Is there something else out there that is comparable? It appears to have been out for a few years now. Have all the teething troubles been sorted? Many Thanks in advance. Kaz.

    In response to Cindy, asking about my repairman’s name or contact. That is I assume she ment me. The dealer was Ross Stewart from Stewarts Sewing Machine Centre in Devonport Tasmaia. As I mentioned Ross was on the phone direct to Janome who gave him advice on how to repair my machine.
    Sorry I didn’t answer earlier but wasn’t looking.
    I still love my machine. It is so easy to use.

    Hi Kaz, You cam use Tajama hoops (or something like that). They are already programed into the machine. I have looked and find that they do not appear to be any bigger though. You can use Magna hoops but they are no bigger. Brother PR machines are very similar and have bigger hoops but they both machines cost heaps more too. Janome Digitizer Pro is the program Janome sells, but Embird is much, much cheaper and does everything any of the other programs do and it suits all brands of machines. You can buy it on this site.

    Hi
    Please can anyone advice me how to insert two lines of text when using a Brother Innovis 1500 embroidery machine? I am only able to complete one line of text and I am sick and tired of reading through the manual time and again trying to find out how to put two or more lines of text using this machine :( Thanks Marie

    I just got the MB4. It starts embroidering fine, then in the middle of a letter it will jump to a different position and start sewing. What in the work is going on? My janome dealer here is very unhelpful. They keep my machine forever if I take it in. Can anyone give me a suggestion?

    I have had my MB-4 for 2 years now and love it, but recently the number 1 needle thread shreds. I have tried everything I can think of to correct this problem, but have not been able to solve it. I have changed thread, needle, bobbin, bobbin case, oiled machine and bobbin, re-threaded machine, etc. I continue to have issues. It does not seem to shred with the other needles. I appreciate any help anyone may have! Thanks.

    Hi, Many of you have commented that their machine jumps out of alighnment. Now mine has started doing this. No-one has come back with an answer or solution. Any ideas what is wrong and how do we overcome this, please? I am starting to pull my hair out with frustration and I too no longer trust the machine. I cannot bear to walk away from the machine when it is going now as I don’t trust it to keep alignment. Help please.

    I have an MB-4…bought it in Jan 07. It takes a lot of maintenance in order for it to embroider without broken threads, skipped stitches, thread loops, etc. But as my first embroidery machine I love it when it is working properly!

    I bought a hat hoop which should be M4 on my screen but it is grayed out. Is there a reason for this?

    i had a problem with needle 3 and 4 on my mb4 . the machine would grind tell you to power down and restart but the problem was still there. when i sent the machine back to the dealer who then had to send it back to jenome to replace the chip,since i have had the machine back i will only run it on 600 speed and the problem so far has not returned. the dealer did suggest slowing it down as i always run the machine on 700 or 800 and was told that may have been the reason for the problem

    I had the problem with my designs jumping off line. I contacted Janome Australia and they denied any knowledge of this problem. They were very willing to help. Their answer was that I need to transfer my designs to the machine via the Digitiser Pro/MB4 progam as this uses the janome language inbedded into the machine. This is the Janome program. I received it as a bonus when I purchased my machine but I never used it. I find this program difficult to understnad but I am trying to learn it. I don’t know if this is the answer or not.

    Missed thread pickup: May be tension too tight on the bobbin- incrementally loosen the tension on both top and bottom.

    Looping: 1. New needle. 2. Try different rotational position of the needle before tightening. 3. Thread may not be best for an MB4 (I use only Robison-Anton). 4. Clean-clean-clean. 5. Adjust top thread tensions.

    Jumping: I had this problem. My repairman fixed it and said it was “dried grease” on the carriage transfer bar. No further problems of that nature.

    Grinding stopping during needle transfer: The poor quality metal used to form the arm that guides the needle into the up/down notch was bent slightly. The needle tab would catch on the tip of the guide and stop the movement. Four trips to same repairman did not fix it permanently. I fixed it myself.

    Needle arm out of position: Re-start the machine while disassembled (needle heads removed). The arm moves to proper position. Then re-assemble. Do not in the future hand move the needles or turn the hand wheel.

    I was wondering if anyone can tell me what stops the rcs unit from spinning on the bar it hooks to on the machine. I bought a used machine that was just the machine and have to order all the parts that were missing. I have the 2 screw knobs that attach the unit but it just spins on the bar. The photos and videos do not show it up close enough for me to figure out what I need.
    Thanks

    I have an MB4, which I love, I have always been thrilled with it but now I have a huge problem, my computer died and the new one has that dreadful Windows 8 and now my computer won’t talk to the MB4 so I can’t get the designs over to the sewing machine. Can anyone give me any suggestions….it is definitely the program as it works with my lap-top (which has runs Windows 7, without any problems). I would appreciate any suggestions.

    Hi as far as Windows 8 goes I had the same problem when I went onto Windows 7. I had an IT friend install drivers to make V3 compatible. I love my MB4 most of the time, but not when it loops up at the needle hole and eats my shirts!

    I have an MB4 which has worked beautifully up until this point. It now does not recognize the #1 needle. I can manually change the needles and place #1, #2, #3 and #4 but when I start a new design, they always go from needle #2, #3 and #4. Never #1. Can anyone please tell me what could have happened so that it will automatically start at #1 like it should do.
