Good news! I did a bench test using jumper wires with all three optical devices and the mechanical switch and it worked. I used the <alt> <i> to look at IN1 and IN2. They both showed "lit." When I tripped Z, Y Master or X, IN1 would go "out" When I tripped Y Slave, IN2 went out! ...

Thanks Shawn. That is a good point. This time though I did think of that. That was the biggest downside. My CNC was never designed for sensors. It was designed around stall homing. So I designed a mount to where the sensor is nearly completly enclosed except for the opening which is recessed 5mm. I ...

Great!! Thanks!!! Much relief on my mind! And thanks for the Heads Up on only including only the normally closed switch contact on the mechanical switch. I thought I read somewhere in one of the manuals that you shouldn't use a 2 wire switch. But now that I have gone back to the install manual I see...

Hello again. I am resurrecting my own old thread. :) It has been about 4 months since I started looking to add sensors to my build. During that time I had to put a hold on buying parts due to just trying to be financially responsible. However, I kept doing research and decided on optical sensors. ( ...

Go "by" and not "at." !!! Great advice! That sorely complicates things on my end... but is something I needed to hear! I have a 36V meanwell PS that I use for my Gecko drivers. I have some regulators that I used for 24V fans. I could probably just connect there. I may do a little...

Hi I am trying to convert my Onefinity CNC over to Acorn. I have made great strides with the help from everyone here. At this point I am trying to put together some parts for my Home / Limit sensors. I was hoping someone could give me some insight before I spend money where I shouldn’t. So I have a ...

Ahh!!! Thanks! I knew I was missing something!

Now that I think about it, even when my original controller used stall homing, once it reached the end it moved back a little!

This is great! I apppreciate it!

Great! Thanks for the reply! Just for my own knowledge... As I understand it, when the machine homes it goes Z then X and finally Y. If the X, Y and Z switches are NC and in series and all connected to the same input, how does the Acorn board know when the X or Y is triggered when the Z has already ...

Hello I am still learning and building my CNC. I am grateful to all of the help here. I have a Onefinity Woodworker CNC. https://www.onefinitycnc.com/product-page/onefinity-woodworker-1 It has a 32” x 32” cutting area. It uses stepper motors rather than servo and it has two steppers for the Y axis; ...
