Unbelevable no end stops no grounding this guys asking for problems selling his plasma cutters he knows just enough to get him self in trouble an posablly injure someone or himself. Vince thanks for the video stay safe 👍🏼
Is it mandatory/recommended to have two end-stops (hall effect/limit switch) per stepper? Can't he just screw in a block of metal on the end to stall the steppers in case of soft limit failure?
Thank you for your support. All production robots should have physical end stops for many reasons namely to prevent damage to the axis from as I stated in the video a person running the axis completely off their table. An end user should never trust a physical switch to prevent this from happening in place of having their chassis built correctly. Thank you, Vince
Thanks for the response. I'm used to the switch being referred to as an "end stop" and now I realize that you're referring to a physical barrier. Issue clarified.
@@corvetteguy50 sorry, i may have been vague. i would typically (i'm not an electrician) return my grounds to a steel bonding surface fixed to the chassis. then from there return to the ground pin on the IEC. (bear in mind 3d printers are as far as my experience extends). im just wondering perhaps said CNC seller done it that way. thanks
All grounds in best practice are to be run to a ground bus bar allocated to your electronics enclosure as you discussed. The power supply you're using for your system if built correctly would be grounded, and using a metal enclosure which would make it conductive allowing it to conduct to your metal electronics enclosure to ground it. Thank you, Vince

You can do whatever you like as its your table, but I believe all machines should have end stops.

the 4th axis is slaved to the gantry !?
Thank you, John, for your support as always. We learn something new everyday...:) Thank you,
Vince
I also noticed their is only one limit switch
on the gantry. how do you square that
Thats, so true. I have to wonder who's buying these?@@johnross3752
so returning grounding to the 3 pin Ground pin not good enough? thanks
Thank you for your support. Please use more details when asking your question as I want to make sure I understand it.
Thank you,
Vince

A piece of flexible conduit for a cable chain, not a bad idea! 🤦♂
Look at the cable chain just dangling off the side
Interesting isn't it? Thank you again for your support John. Vince
Mach3 is not open source, dude probably sells hacked licenses
