Refine MH721 will not longer cut

[NetherX 0]

Cutter has been cutting fine since I purchased it last month.

Now it will not cut. When I send it a cut in SignBlazer, there is no error, but the cutter does not move at all.

I am using the serial cable that came with the unit. All factory settings.

I have tried uninstalling and reinstalling SB. I have tried unplugging the cutter. I have check the serial cable connection. I have restarted my computer. I have even tried another computer.

Any ideas? This is driving me insane.

have you checked your port settings to make sure they are right? In software,should be com1

Yes, first thing I checked. I have even lowered the baud rate to 4800 on both the cutter and in the software. Still no luck.

Cutter will do a test cut perfectly.

If I unplug the serial cable from the cutter and send a job, I get the error "unable to initialize cutter".

If I leave the cable plugged in, it sends the job, but the cutter doesn't cut.

That should prove that the software is communicating with the cutter.

Is there anyway to perform a software reset on the MH-721.

Please don't tell me this thing is broke after only a month of very light use.

Oh I also forgot, I made sure that the head is not on the kill switch.

Mine does that once in a while but I use Flexi... When it acts up I go into production manager delete the job then hit cut from the manager and it will start the cut

Hope this helps

If I am using signblazer, and using "direct" so the jobs are not queued.

I may have found my issue. It looks like my Serial cable may have a short in it.

I will update this thread after I get another cable to try.

I am also having an issue with signblazer. sometimes it will cut and sometimes it wont. it sends the job but the cutter doesnt do anything and i have to restart signblazer. does anyone know what might be the issue?

I switched to the Serial to USB and all those problems went away

Did you also check that the baud rate on the cutter and SB matches?

ours did that too after about 2 months we replaced the mother board it started to work again

then another 2 months replaced the mother board again started to work

then bought a graphtec no problems since then

where are you from? i didnt look before i started to type - if your in a high humid area that is good

do you have high static - it will blow the boards
