MH 721 Locking up - Humming noise

[eclzon 0]

I have about 50 trouble free hours on my machine. The other day during a cut, the stepper motor for the feed locked up and made a humming noise. I shut the machine of and restarted it. It ran fine for about 30 seconds and locked up again. I pressed the online/offline button and ran the vinyl back and forth to see if it was a software or communication problem. It locked again. I checked for any mechanical stiffness on the feed rollers, none. Since the unit would run after a restart and a stepper motor really has few parts in them, I went to the forum. I read about the issues a few had with the mother board so I decided to have a look. I was hoping to find a loose connector. Much to my surprise I did find a very loose wire from the power supply, I think it was labeled "L", not sure. It was just hanging there, the screw about two turns out from just loose. I thought for sure I had found the problem, wrong again.

Well it couldn't be the power supply, the stepper motor is kinda out, and since it does it from the front panel, I guess there is only one part left... The mother board.

I just got a new polaris rzr and was just burning to make some stickers for it. The vinyl finally showed up we started cutting and disaster. I went ahead and ordered a new mother board yesterday. (and more vinyl) I figured I would get the board as soon as possible and worry about who pays for it later. Today, I went to your live on-line support. Great service! the rep was very polite and great to chat with. I bought the unit around August. The rep informed me the unit was probably under warranty, well until I self diagonsed it anyway. The Rep was going to have to speak with someone and get back to me. I am pretty familar with this type of equipment, I built my own CNC milling machine and I keep it running year after year. However, I understand that position about warranty service and no problem if you decide not to foot the bill for the mother board.

I did want to let you know how much I like the machine. It totally amazes me you can buy something as high tech and fun for so little money, you guys have a great product and a customer forever. If it wasn't for your low cost machines, I would have never had the chance to try out this new hobby of mine.

thank you

Thanks for the nice words. 

Hopefully, the new board will get me back to playtime and I am pretty sure it will. I was wondering if you have the board in stock? How do I say this without sounding pushy... OK fine, I can't. Maybe you already processed my order and the board is on the way with the vinyl?

 

I have been waiting almost a one whole workday. You guys must have known my board was going to fail and should have sent me a replacement last week. Just kidding, I was reading the forum again and thought I would try the popular tactic, plus it's kinda fun.

At any rate, please don't let this warranty question slow things down. Like I said, I am more concerned with time than than cost. Damn, I wish I had more patience, it's a personality flaw, sorry.

P.S. you don't have to use the "M" word, you can just use the same term everyone else uses... old

thanks again

Ed

LOL ,

  Hi Ed . VERY glad to have  a new member with a great sense of humor ! 

I used the " M " word ( mature ) as the opposite of impatient , pissy , thinking the world & especially USCutter revolves around them .... maybe that does come with age , But I know plenty of youngters that are mature & PLENTY of older people who are not . There is ALOT of tolerance here from the owners , administrators & mods , but some members get "put out to pasture " dispite the warnings .... But I disagree with you ALREADY !!!  I think you have enough patience

Yes, motherboard in stock, but not sure if it shipped with your vinyl, or if it will ship separately.

Now Mine is doing the same thing...been doing it on and off for 2 weeks...didnt think nothing of it till I read this.

After it gets done cutting the vinyl and I advance the vinyl through to cut it...it will stop after 6 or so inches than I have to let go of the V- button (advance button) press again and it will move 6 more inches than i will usually advance normal after that.

Any Ideas?

Either a control panel getting weak, or the motherboard having issues.

I already have Mother-children issues...please don't tell me I might have MotherBoard issues along the way! :'(  If...and I say "if" that horrible sound happens to me I am so on this board looking for you Ken!

I've only had it for 45 days.

How do I check for the control panel getting weak, or the motherboard having issues?

Jim

[kenimes 42]

Not really a way to test it, but if it continues and does not get better, we should try replacing one of those parts.

Thanks Ken

I recieved the board and installed it. I haven't cut any vinyl yet, just raised the cutter and sent a rather long file to the cutter. It seems to run just fine.

Before I get back to making little sticky things, I wanted to thank your fine customer service department for all the help and quick response.
