General Mach Discussion / Re: Laser limit switch
« on: December 11, 2018, 03:39:10 AM »
After testing that way about 30 times today, my results were up to .02mm out on the software, but generally about .005mm. To me, that's amazing.
I doubt you're gonna get much better than that without spending big dollars.

BTW, this test was done with my homing speed set at 50%, about 1000mm/min. I also haven't tuned the motors/drivers etc since the day I set the machine up. I'm sure there are ways to get a smoother run up to the limit for better accuracy.

My machine is a full Aliexpress Chinesium homejob.
425 oz longs steppers
1605 ballscrews and supported rails.
2.2kw VFD spindle.
all welded steel frame and gantry though.

Hey Mate, After alot of trouble with mechanical switches, I've just installed Inductive Proximity Sensors to my machine for homing, the ones that work magnetically when coming close to steel. At around $2.50 on ebay, I thought it was worth a try and i'm super happy with them. They are easy to install and wire up. These ones will run off 5v.
After much umming and aaahing, I ordered these.


I haven't tested the repeatability on them, but from all i've read, they are very accurate. (.01mm), I'll get back to you tomorrow on that one.

I might have to give that a crack!
Thanks for the info boys.

So you’re saying I should ask for my $5 back because of false adavertising? :D  :D

Thanks mate, that’s a lot of help. I’ll see if we can’t get it running in the morning.

As for the BOB, it should control the spindle rpm, (that’s what is advertised anyway). Quote: “Output 0-10V analog voltage for inverter to control the spindle speed.”
Though there’s no clear indication on how to do it in the manual, or anywhere else that I can see. I’m hoping that someone who has used this specific board will come along and enlighten me.
If not, I might have to stop being such a tight ass and get something a little better.

General Mach Discussion / Control VFD/Spindle via Breakout board and mach3.
« on: November 23, 2018, 05:54:27 AM »

I can't get the forum search to work.. something about spell check.

Is there anyone who can point me in the direction of topics regarding spindle wiring and setup so that it can be controlled through mach3? I'm sure it's been covered here numerous times.

VFD: Huanyang HY02D223B, 2.2kw Chinese

Breakout Board: HY-jk02-M, with relay and analog 0-10v for speed control.

Many hours of searching, fiddling and head scratching have led me here.  ???
I can get the relay to fire, which leads me to believe that the software is talking to the breakout board, but that's as far as i can get.

Thanks in advance.
