just listened to that vidoe again the X makes a bang when it hits the switch while Y does some expected decelerate/accelerate noises. it is coming up against a hard stop, ie the switch running out of room to move? I would halve the $110 and $120 values, and maybe also the home seek feedrates ($24/$25), X must make the same noises as Y.
I did put them very low, like 100mm/minute, even then it did the same thing. It seems like the X-axis doesn’t receive the signal to back off? About the room to move: I tried putting the switch more to the right, but it already has a few cm spare, so that isn’t the problem
If the Troubleshooting tab reflects the switch status correctly the BlackBox is fine. Did you check the Grub screws and other stuff mentioned in this thread yet - there are still several unanswered points If you have doubts about the switch itself, swop around X and Z switches see if problem followed that particular switch (though a broken switch toggled manually will show stuck in the Troubleshooting tab) Pop us a video of the Troubleshooting screen while you press each switch in turn and release each in turn - also showing the switch press please
Alright, answering your questions point by point: - Yes, i did check the grubscrews, they were al tight, just to be sure I tightened them down a bit further. Still no result. - I also swapped the X and Z switch, that also didn't help. In both configurations the troubleshooting window said all was fine. - I will record that video this afternoon! - If there are any more questions that I didn't answer, please let me know!
Please check this closer - videoing the X axis switch on approach and around the time it has to back off - earlier video showed Y axis and quick flash of the screen, not the X axis in detail Have you tried lowering speeds? Have you confirmed this? vs Just please confirm these were seperate tests. One to test for crossed over wiring, the other to test the switch itself That switch took a hard knock at some point - roller all bent backwards so I want you to take the known good switch from Z, take it off the machine, bring it over to X, totally swopping this switch with the Z switch
- I also moved the x-switch 5cm to the right, to make sure it had enough room, and indeed, the switch has enough room to be triggered, and to release. - I tried lowering the speeds, to 100mm/minute for seeking and locating - I can also confirm dat the directions are correct, as described in the message, Z+ moves up, Y+ moves to the back, X+ moves to the right - I did first swap the switch, and after that the wiring, so yes, I did do them seperate. I also put the z-switch on the x-axis, which wasn't bent, that didn't help too
For the other video, yes, your wiring is 100% correct, switch positions are correct, BlackBox is working perfectly. Have you ran any test cuts, like the Hello World? docs:blackbox:hello-world [OpenBuilds Documentation] - to see if the motion side of things (switches are good, so back to the assumption something is going wrong when it tries to move) gets a test - any skipping or other similar issues will show up in a test cut
The Y axis motors sounds good, but the X axis does not - probably not a coincidence that its the same axis with the homing issue Same noise when you jog X?
I did a test cut, which included circles. When it moved X, it was smooth, but Y was stuttering. I did also test jogging up to 5meters/minute, went perfect! But when I sent it back to zero, which goes diagonally, there is that weird stutter again
Check in with the vendor on that noise - they might know what typically requires adjustment or a closer check on their machines for that noise Two more tests for the homing issue: Do run the Hello World, I want to check for some specific clues - even if its just to confirm what we already know (like the limits video, I'll keep wondering until I see it pass that hurdle - as this is a somewhat weird and out of the ordinary case) In your Grbl settings, dial acceleration back down to 10mm/sec^2 (The Grbl default from Grbl v1.1 Configuration · gnea/grbl Wiki ) and do another homing test please
I did the test, and even with the acceleration dialed back to 10mm it still didnt work. The Hello world g-code ran fine, except for when it does the diagonals, it makes that weird noise. I will contact the vendor about that. Sorry for my english, I am not a native speaker as you can hear
The terminals on the DIN rail here: Running mains in them? AC cabling near the low voltage signal cabling may still induce EMI I watched the videos - Was hoping to see a completed hello world cut as in in a piece of a wood - so we can look for telltale signs in the actual cut job result - subtle clues like backlash, leadnut issues, thrust bearing issues, motor stalls, etc all leave clear clues in a final cut that could help us look for issues - The 10mm/sec^2 - not while running a job, wanted to see if slower acceleration helps it "pull off" at the end of a homing cycle - but sounds like you say you did try that too and it didn't. Same error right?
The contact on the din-rail is used as a cable-extension, so that shouldn’t be a problem. However, there is mains running on top of those, so I will separate those. I did the 10mm acceleration with homing too, which didn’t solve it. I will make the sign in wood too!
You have bundled the limit switch wires with the stepper motor wires. That is mixing low voltage (sense) wires with high current power wires, a recipe for EMI.
yes, maybe, probable (-: 'as much as possible' rather than 'a bit' wire spacing is subject to inverse square laws, double the distance gives 1/4 the field strength, so every bit counts. if they can also be 'not parallel' then that is much better.
I only have a 8mm collet for my spindle at the moment, is there a different test that i can run that you recommend?
This is how I have got the wires running now, still the same problem, but I don’t have much more room to spread them further
Yeah i did that, but then it didn’t have enough room to do all the toolpaths, because the letters are too small for an 8mm endmill
OK, any other job with similar details will do, if you can do a pocket and a cut - should give us some clues
Alright, i will do that! On the topic of EMI, I have not yet grounded my shielded cables, could that be a problem?
