This is occurring on a long finish carve. The machine keeps chugging along, but this warning screen keeps popping up. Sometimes it is motor 1, sometimes motor 3. Sometimes each one within a few lines of the other. The only thing that has changed since these warnings were not appearing has been the addition of a web cam.
Stop the job? Unplug the system? Put in a frantic call for help from Onefinity?
This discussion on the BuildBotics controller forum maybe relevant/helpful to diagnose what is happening,
Fault Output - Buildbotics Forum
Pin 21 on the DB 25 connector activates when a motor driver fault occurs. The meaning of āactiveā and āinactiveā can be defined on the āI/Oā tab on the āSettingsā page. For instance, if the āfaultā output is configured for lo-hi, it means that the pin will be low (ground) when it is inactive and high when it is active.
Motor driver faults can occur due to incorrect motor wiring, a defective (or incompatible) motor, a bad FET, or a defective motor driver. Driver faults are also reflected on the āIndicatorsā tab on the āControlā page.
The meaning of high has changed with our latest controllers (those delivered after September of 2021). A high is now nominally 5 Volts whereas high was 3.3 Volts in older units.
The newer controllers also have an auxiliary 15-pin DSUB connector and it also presents a āfaultā pin. It is wired directly to the motor drivers and its state is not configurable. If the output is at 5V, no motor fault is being detected. If it is at 0V, a motor driver fault has been detected.
Hey Jim,
can you let the controller cool down (power down a few hours) and say whether the issue persists or only appears after a period of vigorous activity, and if so, how long until it reappears?
By the way, whatās the ambient temperature in your workshop?
It is 70 degrees F constant. I wouldnāt call it vigorous activity - it is a 1/16" ball nose running at 8400 RPM and 40IPM. Depth per cut is about 1/16". It has been through rigorous activity - cutting cabinet sides and drilling the shelf pin holes was a LOT more demanding (physically) than this work. Then again, this 3D job has 266,000 lines of G-Code. Maybe the controllerās brain is running hot from all the calculations ā¦
I hesitate to say it (because we all know the problem will immediately reappear if it is mentioned) but the issue has not reappeared since I posted the first note in this thread. There are roughly 2 hours remaining. Iāll shut things down for the night and see if the messages reappear during tomorrowās workday.
You, sir, are a mensch. Always there with a cheerful helping hand. I thank you.

Thatās because his is sitting in his living room in all the boxes 
Once he sets it up weāll never hear from him again because heāll be making chips 
Assuming his wife is tolerant enough to allow him to power that puppy up. At least mine is in the garage.
Jim, you are a hard, hard man. Good on ya! 
My wife would have killed me if I left the boxes in the living room for even a day much less a week. I always thought she was pretty tolerant (this isnāt the first time Iāve bought something like this with not much plan as to what to do with it) but there are lines even I wonāt cross.
So, did you have to seek her blessing to make this big purchase; or, did you buy and ask forgiveness after the fact?
And regarding our friend with the boxes on the living room floor ā¦ One must be careful about pushing spousal boundaries. Wives are brilliant, loving, and supportive. Thereās a reason theyāre known as āthe better half.ā When made to be angry, they can become āTomā of āTom and Jerryā fame. All sweetness and light while theyāre plotting their revenge. You never see it coming, and then you are laying on the floor in pieces. Iāve been married for 43 years. Wouldnāt change a thing.

I bought a book about building my own (I have an idea of making a set of 3D carved entry doors for our new house so I needed something larger than the Shopbot Desktop). The doors were her idea. Then we were shopping for lights & fixtures & things like doorknobs and she saw one she loved but not the price (almost as much as the 1F). I suggested I could make these things for her. She just sighed but did not say no, donāt do that. Thatās kind of like āsure, you should do thatā around here 
We just celebrated 40 Saturday. I should have been more attentive & helpful with the kids but weāve got time to make up somewhat for lost opportunities.
Congrats on the 40. when you reach 50 you are off probation.
I should be off now - I met her when we were 16 and got married in college. I donāt really remember much of life without her 
Always told her we can never divorce because itād be impossible to break someone new in
We married when I was 20 and she was 21. I tried to get off probation at 50 years. She said āOh Bud, you are old, fat, bald, ugly and have no money, go for it honey you are any womanās dreamā.
That was 54 years ago and I guess she was right!
Met at college when I was 17.
3 kids and 6 grandchildren later itās too late to change now.
Life is good.
Hey Jim, hey Jim,
Jeez!
My goodness, when I hear you talk, I must consider myself a very happy person.
Of course, every person is a unique individual, and no matter who you are with, it is normal that you sometimes get the impression that the other is not from the same planet as you.
But I donāt know whether I should laugh or sympathize with you when I read what thoughts you have or should have had when planning the purchase of your CNC.
That sounds at times like youāre with an enemy. āDonāt cross linesā, isnāt that war terminology?
I am obviously in a minority here, because I am neither retired, nor do I need the CNC machine for my hobby (my hobby is something completely different), nor does anyone at home lack deep conviction and trust in the joint investments.
But I think this is all about respect. I believe that you should respect everyone else, especially those you live with or work with, but you also get unhappy when you are with someone who doesnāt respect you.
Yep. My wife never even asked how much it cost. Itās just one more of my toys. She would likely be more interested if I go ahead with the Tormach Iām noodling. But thatās a year off. Or maybe when I retire.
Guys, my note was tongue in cheek. All is splendid in Tomahawk, Wisconsin.
Is this the married young and for a long time club? If so Iām IN. Married at 20 she was 18, been married now 48 years. and have a onefinity journeyman. I think I qualify. lol.
Yes, indeed. In a crazy world, a solid and deeply loving marriage is a gift. Glad to meet you.
Jim
