Black Box controler

I have a question (AGAIN)
The other day I was cutting out a project on my CNC router, was having some issues with it but wasnt present when it was happening, so I decided to sit and wait it out to see what was going on. The project would cut out as planned then about the 3rd or so cut around it would get back to to starting point and just sit for a sec the go off in a whole diffrent direction like it was starting over or something. I shut down the computer then the router, I found a loose wire on one of the limit switches. Would this cause the machine to do this? I have sense fixed the wire and re-uploaded the orginal confiruration on the BlackBox, and ajusted the Axis. But wonder if this could have caused the issues

Thanks,
Jerry T.

 

Normally Open, I dont remember any error messages But to tell the truth I was more worries about the router digging into the wood so deep and shutting it down

 

I’m starting to believe it the Black Box it self. I’ll randomly run a code with out the bit on it makes one good pass then hesitates the run off in another direction of won’t even turn one of the steppers on the Y it just random, I know the code is fine because I’ve run the whole program before with no issues a few weeks ago. I just got this Black Box in December. Any ideas help please

 

Open Builds Controller windows 7 pro computer

 

Unfortunately my computer won’t update from windows 7 it’s worked fine up until now. I’m gonna try a different file tomorrow see if just by chance it’s corrupt some how. Planning buying the Open Builds Controller this next year after I get the Black Box paid off

 

I have the coils hooked up correctly on the steppers, it’s been running great up until this last week

 

Ok That makes sense! Its always the same stepper motor on the Y axis thats doing it. Its just ramdon when it happens. Never the same time. But still dosent explain why it would make a complete pass or 2 the just stop for about 15sec then start off on a whole diffrent direction.

 

it shows it’s moving and it gos threw the steps in the read out I guess you call it but it’s not moving, then all of a sudden off in another direction

 

Ok I guess Ill be tracing wires next weekend. Thanks to all for your help. I'll let you know what I come up with after compleation. Thanks again

Ok I know it’s been a few weeks since I posted but was busy but this is what I found, looks like some for the wiring on one of the steppers was exposed at the solder , and would randomly touch. Sense I was doing a partial re-wire I also decided to extend the working area 200mm I will be trying it out today after I calibrated the machine a couple days ago. I’ll keep posted when able. Thanks to everyone for your help in tracking down issues

 

UPDATE** Well it wasn’t the wiring well at least it’s not the wiring now x axis still going haywire at random and every once in awhile it’s one of the Y axis I’ve done a complete re-wire job but still having issues so I’m sending the controller back for a replacement ‍ I’ll keep ya updated after a replacement is sent, I’ve only had this thing sense mid November 2023

 

Talked to open builds there saying its more then likely something to do with a fault that needs to be reset. So I ve stopped the return and will wire it back up and try there suggestions. But I dont under stand how it could run just fine for 4 months and just all of a sudden start doing this Ill get the pictures today Ill have to get the Grbl settings from the computer in the garageI just ordered the INTERFACE CNC Touch also the computer I have is old not to mention only windows 7 pro. Thanks Peter I'll get you that information later today

 

Thanks Peter for you insight I know the interface wont cure the issue but been wanting one for awhile now> Think the wife will have a fit if i put the portable A/C unit near the machine . but to tell the truth it get over 115* or higher here in the summer So Im gonna have to cool down the machine at some point. Right now its in the mid to upper 80*. Ill get that information you requested later to day . Thanks

 

Might be a few day before I can get those pics to you. I got to hook it all back up and I work M-Thur. But will get them to you soon. But this is what I took this morning so far

 

I gave you the specs on the motors awhile back in a drffrent post just before I was talked into BlackBox. If I knew how to find old post but let me see what I can do I belive you said they were fine for my application

 

Ok I found the thred I made back in November about the steppers and your reply

Your reply
So quick google on the 57hs56-3004a08-d21

Voltage (3) is good, will accelerate nicely
Current (4) is good too, BlackBox will do fine with this one
Inductance (6) is a little on the high end - will be a little lower on top speed than our motors. But as you already have them, I would say use them. Just keep in mind you may need to drop Max Rate on these about 10-15% from our profile defaults

 

To be honest I think I did but not sure!! But let me get it all hooked back up. And Ill get back with you with more pics and videos in needed as for the PSU (REALLY) I though being from Stepper it would be a good one If I need to replace that Daaaaaame! I just placed the Dust extraction setup on there havent even had a chance to use it yet so I can fix that.
