Troubles with the embroidery machine when doing Photo Stitch

Original text by Marina Belova

Sometimes I embroider portraits. I usually do that on the Velles 15 because I have this little flat frame from the Tajima machine that cannot be inserted into Velles 19. Therefore, I do not have a choice which one of the machines to use. During the embroidery process 3 problems always occur:

Trimming (the machine does not trim the threads, and there are so many trims that I sometimes don't know what to do).

After the trimming, the thread comes out of the needle. Taking into account the number of trims, it is a disaster.
About 50 or 60 thousand stitches (the machines stops correctly with the main shaft at 100°) the presser foot does not raise anymore. On the photo below I encircled the control panel together with the main shaft indicator and thread take-up lever (I believe that's the proper word for it) in the same position, and the foot is at the bottom, only slightly raised above the fabric surface:
The funniest thing is that when I take the portrait out and embroider something ordinary, nothing like that ever happens, even if there is a lot of trims.

I don't try to solve neither first nor second problem. The first because I haven't yet got to the trimming knives and the information on how to adjust them. About the second I tried to tell in my previous article. Just now I was meddling with the options on the control panel, and things seem to have improved, but I'll just observe for some time before rushing into battle with the picker. In order not to be preoccupied, I just switch off the automatic trim and remove all the jump stitches manually. It's dreary but quicker than having to deal with trimming troubles (some of them are rather nasty — one day I'll tell about them) and keep inserting the thread into the needle.

The third problem is easily solved (I discovered it by trial and error): I lubricate this part of the machine two or three times during the embroidery — with the ordinary oil, not one or two drops but much more:

Though the 2 paragraph the user guide says that it should be lubricated once in three months, I pour oil into this opening at least once a week, even when there is no photo stitching. As the result not only the needle bar raises all the way, but there is much less noise, too. So, this brings up the question: is there something with the oil that it takes much more to lubricate the machine, or am I doing something wrong?

I am now looking at my Velles 19 and beginning to think that if there is no such opening there, problems like that surely won't occur?
