Re: MBX Problems!!!!!

Jim_Stutsman <jim@...>
 

In my experience those who think they are computer experts have the most problems. That's because they charge ahead without reading instructions, and then when problems occur they immediately react without thinking, making the problems even worse. Yes, you can get over this. Start by getting yourself a safety net. Make a complete *image* backup of your computer to an external disk drive. This is something everyone should do anyway, so it's not wasted effort. One of my favorite programs for image backups is this one:
http://www.acronis.com/homecomputing/products/trueimage/
This way, even if things go horribly wrong, you can put your computer back like it was.

After you've made your backup, insert the MBX DVD in your computer and begin the installation. Read each and every screen before clicking the NEXT button, and be sure to check all the options except those involving languages you won't need. When you've done that you should be ready to go. Use the included DVD by Trevor Conquergood and explore the program. Take deep breaths and ENJOY learning something new. Learn the tools and use the program, and soon you'll have all your family and friends pestering you to embroider things for them.

Remember the old saying - Buy a woman a vacuum cleaner and she'll kick you where the sun don't shine. Buy her an embroidery machine and you won't see her for days at a time! That may not be quite how it goes, as I'm paraphrasing from memory. In any case, please keep us informed on your progress, and we in turn shall cheer your efforts!

For exception access violation problems there are a couple of things you should try:
1. From the MBX Windows menu (Start -> All Programs -> Janome Digitizer MBX) choose "Delete Recovery Files". If, in the heat of editing and designing, a design gets corrupted and causes a crash, Digitizer MBX will attempt to recover it by re-opening an auto-saved copy. If that copy also happens to be corrupt you get into a crash loop. Using this option will purge all saved copies and allow the program to open normally.

2. Another crash-maker is corrupt default settings. In the very early days of Digitizer corrupt defaults were solved by uninstall-reinstall, but thankfully there is a program to do that for us now. Using the same menu as above, choose "Revert" and select all available options. This will reset the defaults of Digitizer MBX back to their initially installed values. Usually this will fix most problems.

I'm guessing that you are in the US. If so, you may have received the first release of MBX. There is an update for that version here:
http://www.janome.co.jp/e/e_downloads/digitizer_mbx_v40k.html
This may not correct your crash/freeze problems, but you should definitely update to 4.0K if you are not there now.

If you continue to have freezing problems it could still be a hardware problem. The CPU fan may not be properly attached to the heat sink. You would not notice this with programs that don't do a lot of "work", as they computer doesn't get hot enough. It might be worth installing a temperature monitoring program, at least temporarily, so you can see if the freezing happens when the CPU is very hot (How ironic!). Google this:
cpu temperature monitor
There are lots of these out there, many completely free. Good luck!

Laptops are tougher, because they are full of tiny parts and just taking one apart is a big challenge. If the computer is a laptop, have it checked by a professional. Cooling fans often fail in laptops, and need to be replaced.

Foot question

judyjanome <judyjanome@...>
 

I am receiving my pack of the month this week, and the dealer opened it at my request to find some type of embroidery foot with a special tool to cut or make fuzzies after you do your embroidery. Does anyone know of the foot mentioned? It said it was for all MC embroidery machines. Judujanome.

Oh, Barbara Jean, can't you imagine the fun we'd have. I agree with you but I'm sure I'd be one of those that forgot to change something and end up with a broken needle or two. So far I've been lucky. One time I forgot to change the plate on my Horizon 7700 and hobbled my fabric to the foot and needle plate when I changed to zig zag - lucky that the default was the same width. Can you imagine how cross I was when the fabric didn't feed. I was also stupidly angry at the machine - like "what's wrong with this thing?" mad.

I'm glad we challenge the designers - they need our input so that everything gets improved with our machines and the next ones to come.

Re: Another question

Anne <csarina43@...>
 

That was the problem with the cuhsion cover I was quilting. but when I switched to the hopper foot and ordinary stitching the tension was perfect......using the T shirt quilting key the tension was rubbish.

I will try tightening the needle tension and see hoe it goes. I have finished the cover now, but have another one to make. I'll make up a sandwich with the wadding and see if I can get it any better.

I will also use the straight stitch plate rather than the embroidery plate, see if that helps.

I was using ther same thread in the bobbin as in the needle.


Re: Embroidery satin stitching tension

Donna Morton
 

I’m curious to know which brand/type of embroidery thread you have selected in the SET menu as your default thread.  If it is Janome Acrylic, then the default tension is lower than for the polyester and the other brands of rayon thread.  If you are using Janome Acrylic, try changing to another brand for your default.

Subject: [janome12000] Embroidery satin stitching tension
 
 

On the 12000, has anyone had problems with little or no bobbin thread showing on satin stitching segments.  I'm trying to figure out if I have a problem that calls for me to have to haul the "tank" (my affectionate name for the 12000 whenever I try to move it because of the weight) in to the dealer after only 2 weeks of ownership or if this is just an idiosyncrasy of the machine.  I've described what it is doing in more detail below.
 
I've been experimenting with bobbin threads and bobbin holders in the embroidery mode and am finding that on satin stitch columns and filagree style stitching (graduated satin stitching) I'm getting no bobbin thread showing when using the yellow dot bobbin holder and only a thin line if I switch to the red dot bobbin holder.  At first I thought it might be the bobbin thread I was using (the Janome prewound bobbins) so I visited my dealer and when I described the problem, she indicated that they've had a few reports of inconsistencies with the pre-wounds and showed me what they were using in the store with the yellow dot bobbin holder.  It was a much finer, slicker, and thinner thread.  So I got some of it and came home and stitched some more and had pretty much the same results on my test block letters.  So then I decided to try the built in butterfly design with my name in script under it.  The underlay and weave-fill stitches looked fine  from the back with mostly bobbin thread showing and just a little bit of top color.  But anywhere it was doing satin stitching it really pulled the top thread down and around with little or no bobbin color showing.  The results with the red bobbin holder were almost the same, only a slight line of bobbin thread through the back center of the script text.  I switched to sewing mode with the red bobbin case and it appears to be correctly balanced on the regular sewing and decorative stitches (using regular thread in the bobbin that was the same weight as the top).  So is this really a "problem" or something I'm worrying about needlessly?  


Re: Embroidery satin stitching tension

Jim_Stutsman <jim@...>
 

Before dragging your "tank" in for service I would recommend a more controlled test. Start with a properly stabilized fabric in the 140 x 140 hoop. Put a full bobbin in the machine, wound with whatever you plan to use, or a pre-wound if that's your choice. Thread the needle with a good quality embroidery thread in a contrasting color from the fabric and bobbin thread. Enter 2 or 3 uppercase letter I, in the medium (18mm) size. Stitch them out in the top of the hoop, leaving space for additional stitchouts. Stitch a sample with each bobbin case, one on each edge of the hoop.

Next remove the hoop and look at the back. Ideally you would see 3 stripes of thread on each letter, with needle, bobbin, needle in equal amounts - 1/3, 1/3, 1/3. If they are close to this, you are done. Use whichever bobbin case gave that result.

If you see too much needle thread, with almost no bobbin showing, then there is not enough needle tension. If you see almost no needle thread, then there is too much needle tension. Touch the SET key, then the Embroidery Mode key (left of the flag). Page 1 of 6, first item, is the adjustment for automatic tension. To increase tension (too much needle showing) touch the + key. If the bottom is mostly bobbin showing, touch the - key. Just make 1 adjustment, then stitch another sample. Repeat until you have it right, or run out of adjustments. If you got it right, go celebrate. If not, you may have to drag the tank in to see your dealer. In that case you should take a bobbin with you so they can test it with what you actually use.

Before you round up a crew of stout men to drag said tank out to your car, you might also try adjusting the yellow dot bobbin case. Since you are happy with the red dot case, DO NOT TOUCH that one. With the yellow dot case, if you have mostly bobbin on the bottom, turn the slotted screw at the 6 o'clock position on the case clockwise about 1/8 of a turn. If the bottom has almost no bobbin showing, make the adjustment counter-clockwise. Make only SMALL changes and test after each one. If you don't see anything changing after 3 adjustments, or you have adjusted the screw as much as 1/2 turn, then it's time to see the dealer. If you get it right, rejoice and use the yellow dot case for embroidery.

On the 12000, has anyone had problems with little or no bobbin thread showing on satin stitching segments.  I'm trying to figure out if I have a problem that calls for me to have to haul the "tank" (my affectionate name for the 12000 whenever I try to move it because of the weight) in to the dealer after only 2 weeks of ownership or if this is just an idiosyncrasy of the machine.  I've described what it is doing in more detail below.
 
I've been experimenting with bobbin threads and bobbin holders in the embroidery mode and am finding that on satin stitch columns and filagree style stitching (graduated satin stitching) I'm getting no bobbin thread showing when using the yellow dot bobbin holder and only a thin line if I switch to the red dot bobbin holder.  At first I thought it might be the bobbin thread I was using (the Janome prewound bobbins) so I visited my dealer and when I described the problem, she indicated that they've had a few reports of inconsistencies with the pre-wounds and showed me what they were using in the store with the yellow dot bobbin holder.  It was a much finer, slicker, and thinner thread.  So I got some of it and came home and stitched some more and had pretty much the same results on my test block letters.  So then I decided to try the built in butterfly design with my name in script under it.  The underlay and weave-fill stitches looked fine 
from the back with mostly bobbin thread showing and just a little bit of top color.  But anywhere it was doing satin stitching it really pulled the top thread down and around with little or no bobbin color showing.  The results with the red bobbin holder were almost the same, only a slight line of bobbin thread through the back center of the script text.  I switched to sewing mode with the red bobbin case and it appears to be correctly balanced on the regular sewing and decorative stitches (using regular thread in the bobbin that was the same weight as the top).  So is this really a "problem" or something I'm worrying about needlessly?
