Prime cause of a flame-out???

[davek0974]

System has been reconfigured, moved a jumper on the BOB and changed Output1 settings in Ports & pins, will be testing it soon but signal appears stable now.

Tom was the one that explained the bypass trick to me. It has worked flawlessly since I did it. It involved putting a shorting pin on a set of pins inside of the DTHC case.

(;-) TP

That only works on a REV 14 or higher card. There is no jumper (shorting pins) option on earlier cards. We do not encourage users to open and make board modifications The cards are all surface mount technology and densly populated. Since you (Terry) dabble in electronics and software macros and have the spare time to make mistakes and then correct them you are an exception.

Then I must have a Rev14 card

Honestly, i can understand your caution in some ways, but if this very simple mod had been explained to me 10 days ago, I might not have wasted time, materials and money on it.

It's a clearly marked jumper, took 3 minutes to alter and reconfigure and - job done (hopefully)

HIYA TOm is is NOT about dabbling in electronics or spare time. It is about watching a fellow plasma cutter STRUGGLE with a problem and not offering a possible solution. The OTHER solution is far from the best solution as at the time I had the problem I went through 3 PCs and still did not solve the multiplexing problem. YOUR fix( rerouting the signal to a NON multiplexed signal) solved it first time out. IF you did not want anyone to know about it WHY did you publish the info and make it publicly known ?? I do not understand that.

And for the record there ARE some quirks to rerouting the signal. BUT I can live with those as long as the torch fires when it it suppose to AND stays lit (;-)

I DO understand that some need to keep their hands off. AND I do understand YOUR situation with support. BUT at least make the offer of a solution and LET the user make the decision to do or don't do the fix. A simple private email to Dave would have worked fine.

Where's the "Like" button when you need it

I ran five parts today, 23 pierces and a few metres of cut, not one flame-out, steady as a rock

I have another big sheet to run soon, that will prove it fully but I have a feeling it is now fixed.

Would have been nice to get there earlier though

Good stuff, plenty spare PC's to go at now then

Yep, got them both loaded with Mach3, just plug and play.

Could have done without the headache though, could have been fixed much sooner

[davek0974]

Cut a full sheet today, couple of hundred pierces, plenty of fiddly cuts, 100% rock steady torch now, not one glitch

I chased problems with my machine for a year before I found out it was a PC issue. As stated - Mach3 requires some major back/forth talk between the PC and motor controller. I installed a refurb PC with 2.5ghz processor and as much ram as it could hold and left the Windows 7 on it and I have never had a fault since. I had flameouts, faults and just general weird stuff happening all the time. Now Nothing.

For future reference, here is the page from the manual that shows the changes needed to the BOB and Mach3 settings.

Since doing this my system has not missed a beat, 100% success.

Hi Dave

Fancy putting the link back up again but in a jpg format
Just cant seem to get the .tif to open with anything

Thank you, just wanted to understand for the memory bank
read and now filed away for future use if required

EtherCut units have a later revision of the BoB abd handle the outputs differently so there will never be a need to do the change in the document.

[exapprentice]

Hi TC thank you I will erase that from my memory bank yet another +for the ethercut system

[davek0974]

Thanks Tom, always good to have a clear answer on a reference thread.

For those with the older system on maybe a slightly imperfect PC, this fix is like pennies from heaven - it really does fix those annoying little flame-outs that just get brushed off as "one of those things", my machine has not skipped a cut since doing it.
