I suspect it is, in fact, a connection. A single wire on the motor that stalls is either fatigued inside the cable, or broken inside a connector....
Look into inductive or capacitive proximity switches/sensors. All of them should be IP65 or IP67 by default.
Hey, it was just my 5-year too! Go us!
I haven't used one, though I've seen them mentioned before from reasonably reputable-looking places and I've looked into it. The idea is solid,...
Yeah, I like the idea of a completely self-contained device, but trying to put a realtime kernel and an offline I/O module into the same piece of...
Either one is fine; some people prefer normally closed because a system failure would be in the error position (ie. open, and stopping the...
I've had good results with StepperOnline stuff. The best drivers I've used recently (albeit with a lower current capacity of 4A, but I'm running...
Read this page: gnea/grbl $H is "perform homing cycle", not "go to working 0,0,0". Judging from your second question, you don't have homing...
Optical toolsetters are usually laser-based, not IR LED like limits. I'm assuming this is so they can be focused to a very narrow beam with a very...
Upon further consideration this morning, my "inherently" should really read "under certain conditions", because yeah, ground should be ground. I...
First thing I see on the diagram is you have your DC and AC sharing a common ground bus. Seems like this inherently means you're putting -120V...
I need to go back in and update this with some modern pricing and correct some inaccuracies as I've learned over the last couple years, but this...
If it were steps/rev calibration, the offset would be proportional to the distance travelled, by definition. It would be travelling an...
While I'm not sure I would call that a "robust" machine (;)), it's clearly more or less suitable for the task. The inner ring of your doughnut...
What does the finish look like when you cut square and say, hexagonal shapes out? Hard to diagnose things from a single data point. Also are you...
The fact that it's 1mm regardless of part dimensions suggest that it's either a mechanical or software problem, not an electronic problem. It...
What's wrong with a cheap arbor press? This site gives a PSI number on their pneumatic unit:...
If you attach a suitable head to your existing CNC experiment, you could use a simple 555 square wave generation board as a head driver (assuming...
Minor update for some notes to get them out of my head: I was doing some research yesterday and it looks like the target drawbar force is 2500lbf;...
I have no idea how it works on RasPi, never even looked at it, I use Arduino. Re-read my original comment carefully, that would be the reasoning...
