Help with Problem X axis Stepper Please

[howser37]

Thanks Graeme, well i am back up and running again. I removed the x axis stepper cable completely and it tested fine, i then rewired it using different connectors and fired it up, all seems to be running fine at the moment, but it was running fine last time i replaced the chip for a good few hours too, so we will see what happens. I have switched the over the x axis stepper cables so that if it is a problem from the motor/ cable it should blow a different driver next time and atleast i will have narrowed it down a bit more, if the same driver blows i can probably assume its more something inside the control box.

Thanks for all the help so far, fingers crossed :-o

Sounds good! Let us know how it goes.....!

I've used choc block in exactly this situation and it seems to work OK but I have wondered about these instead. Spring-loaded so more vibration-proof and even include access for a test probe. They come in 2, 3, and 5-way versions which could be useful in some of the junction boxes on my machine where, say, multiple limit switches with common ground connections all meet. I find it fiddly trying to use choc block for multiple connections as you end up with two wires in the same hole, which never seems satisfactory.

They look really quite smart, and certainly seem to get the thumbs up from the electricians, judging by the reviews on there. They don't look like they have a way to fix them down though, in the way you might screw a choc block to a panel. So worth bearing in mind for some applications. Don't some forum members use something similar on DIN rails in their control cabinets? I seem to have seen something along those lines in pics on the build logs.....

I bought this kit from screwfix http://www.screwfix.com/p/wago-basic...5pcs/48808#_=p I haven't used them on anything CNC yet, but for solid core domestic wiring they are very good and quick. For multi strand wires I crimped an uninsulated ferrule on to get the wire in to the block. That was fiddly, but better than choc blocks.

I had a couple left behind by an electrician after some work in the house which I have used on my own router and like you, I crimped on ferrules to stranded wires. They seem very effective, slightly larger than the equivalent choc block but easier to wire. I just left mine floating in one of the plastic boxes I use as junction boxes (which I was buying from Maplin but now 3d print).

Wago do junction boxes, you might like to adapt your 3D prints accordingly http://www.screwfix.com/p/wago-abox-...Fa237QodaegHvA
