Hello all. I m looking to add Hall effect sensors as homing sensors, just curious what Masso or anyone s that s already done this, recommends? Thanks!

Hey mate, Masso sell hall effect sensors if you look on the products page

They are a beam??? really... ha, I thought I tested that they only worked with metal... oops
My bad @homebrew_cnc !
I actaully have PNP hall effect sensors on mine. All three axis until I tried to move one and.... it died...

These type are easy mounted and PNP which is what you need on the Masso (applies voltage when activated, NPN short to ground when activated)
Well yes, if you use a metal vane to interrupt the beam they will work with metal ;-)
Yep, they are a photo-interrupter. I have them on my machine and they work well - but I don't have a very dirty environment either.
From my point of view the only disadvantage is they require 5v power. I don't have any other module etc that requires 5v so it's another power supply. I see your Hall Effect devices will run 10 - 15V that would be nice for the Masso photo-interrupters.

Well that link wasn't the exact one I have. mine was ataully 24V which was great. Ultimately I should have just replaced it buit I had 3 of the photo-inteerupters I bought originally with the Masso so I just connected that up to the X. I have a 5V power supply within my control box but FYI... The masso's USB is 5V. For the minuscule amount of current switching you could slice a USB cable (just use the black and red pair).

it would be very neat ;-) also my OCD with step down transformers would frustrate me haha. 240vac-24dc-5V. I'm sure there is a header inside you could solder to so it's uber neat ;-)
Without a doubt these are the best sensors that I have ever used!
They are a bargain @ 6.00 and there are accessories that you can add onto them also if you need.

Small and effective, nice! haha I guess the 'best job' is just working every time right!

My Multicam has them standard, what doe most others have? Moving part switches like reeds wouldn't really be suited in industrial machines, I would imagine opto could be an issue too with dust and chips flying around a machine day in and day out
Of all the different styles of CNC limit switches available I feel these Hall effect sensors are the best choice for CNC use.
The only consideration is that if you're cutting a type of metal that can be attracted to a magnet, then you'll want to make sure the magnet stays clean.
Usually this is very straight forward to do and not a concern. Hall effect sensors are usually much easier to incorporate and install into the CNC, which is another big advantage.

I looked at the Tindie sensor, looks good for US$6 ea plus $9 postage to Australia. I found a sensor in Australia for AU$5 plus $3 postage. I've ordered a few to play with. I'll let you know how they go.
