Cobra class 4 sewing direction problem

[dgkfit]

hello,

   thank you all for your help with my last issue.  so after having a cobra owner come and see my class 4 machine, we discovered that it sews in REVERSE when the selector is in the down position.  this makes a bird's nest mess of thread, and so stitching takes place.  the machine has never sewn right for me since getting it home almost a week ago. BUT, it sews in forward when the handwheel is rotated toward the user.   

  is this something in the servo motor adjustments or is it a serious flaw in the internal gearing of the machine head?   if it is in the servo motor adjustment, where is the video/printed instructions on how to adjust the servo motor?  i have searched youtube and they just aren't there.  i have watched all the videos on the leather machine co site and they don't address the subject of adjusting the servo motor.  it is tricky.

  thank you all for your help.   dale

Gosh! Does the servo on your Class 4 have a numeric LED display with up and down push buttons? If so, there is a setting (S something) that controls the direction it rotates in. I don't have any paperwork handy right now for these button options, but somebody else probably does. Leave the machine alone until we get these instructions for you.

Well I do have some instructions in Chinglish   Called " 2 The Normal-Reverse transition Setup For The Motor"  

" Motor manufacturer set is the reverse transition. If you need to reset: when motor stops, press the arrow down (button symbol on motor) for several seconds, when LED is "SET.0" press arrow up button with 2 times; when LED is "SET.2", then press the arrow down button again, Led is "roT.E" or "roT.P". If you want to change the transition, and you could press the up arrow for switch of the transition . 5 seconds later, the set pattern will be automatically saved"  This is exactly what's written in the instructions, part from the arrow up and down which are pictured by an arrow symbol. English or "Chinglish" are not any of my native language. I've would perhaps use the word direction instead of transition? that would have made it simpler for me anyway. I have not tried this for awhile on my motor (600 watt brushless cobra servo motor, 220 volts but with the same instructions as the 110 volt version). Anyway, running a machine in the wrong direction is not a good thing to do. It might have caused some thing to unscrew/ loosen or knocked out of position. I would recommend you take contact with Steve and tell him about it. It might be trouble regards the warranty later if you don't . It's really not that difficult to adjust these motors when you get to know the display, it's been a long time since I hade to turn /push on any buttons on it. I have used it on the same max speed settings all the time (around 1000 rpm) have not needed to do any thing else with it (that's a good thing  )

Good luck

Dale, did you understand something of this "Instructions"

 Here's one we rewrote & should be the same for your motor.

"E = reverse, P = Normal". Should be obvious to anyone, perfectly logical - NOT!

Dale,

A call to Steve would have solved the problem. Not sure if the machine is new from Cobra or second hand but either way he would help because he wants you to be happy and say great things about his product and service.

 

It is disappointing for any dealer, myself included, to see paople asking questions on a public forum.

it is interesting that dgkfit asked that question about the cobra4, I recently bought that same machine brand new and it was drop shipped from leather equipment co.  Now if dgkfit is a newer newbie than I, I can understand the frustration with the machine, I had difficulty setting my up as well and sent the original head back and received a new one in its place, but after throwing the original completely out of time and was unable to reset the timing Dave sent out the new one KUDOS to David.  However once getting the new one and painstakingly go over everything and making sure that it was threaded properly I asked my wife to come out and watch as I was going to try and sew something with it, and low and behold it punched holes and no stitches, but my wife said wait a second do that again and I did and then she said out loud hay that thing is sewing backwards.  So I reset the motor with my sons help with my disabilities once I get down that low I cant get back up and I cant bend over so, we got it going in the right direction and it sews great.    So the moral of the story is that those motors must be coming out of China going in the wrong direction!!!!!  Maybe someone should look at them prior to sending them out.  Contact me Dave so I can let you know how much thread you can send out for this little tidbit of info!!!

I note that Cowboy Bob's instructions above state that the default (as shipped) direction for the motor is reverse - as the two gentlemen on here appear to have confirmed.

We had the same problem with this motor,it switches direction (or goes to default) in shipping,one of the two reasons we quit using them.
