Homing and Limit Switches - Homemade CNC

- Installation of limit and homing switches on my CNC in Mach 4 using an Smoothstepper (ESS) by Warp 9. Upgrade of my breakout board from 5 inputs to nearly 34 input signals. The new breakout board utilizes two ports on the ESS. Part of my homemade CNC machine router out of all wood series. C25 Breakout board.
What breakout board did you end up going with? I’m finding the same problem with limitations on inputs with my c11g BOB. I’d like to have limits for each direction on each axis, but even with my current bird there aren’t enough to do a single switch per axis.
I believe it was a C25. I'm not at the shop right now so I'm trying to remember from my ever fading memory.
@@OldGuyWoodworks Thanks, I just came across the C25, and I purchased it. My follow up question is can you control a spindle with that board, or do you need some other auxiliary board for this? The reason I ask is because I started with a C11G BOB and I'm having issues with the outputs after hooking up 12V power for the Spindle side of things on the board. Hoping I can still salvage it, but if the C25 can cure all my problems and give me more inputs, i'll ditch the C11G idea.
@@strikermed I control a spindle with mine. I control the inverter which in turn controls the spindle.
@@strikermed I think my original was a C11g. The C25 is cheap to replace.
I would like to know more about you home build machine
What specifically would you like to know?
@@OldGuyWoodworks what are the spec on the angle iron you used for the rail guides. And how have they held up?
@@warchildcustomcreations 1/8" thick 1"X1". Holding up very well. I don't see replacing them any time soon.
As a follow up. I wouldn't use angle iron on my shorter axis. It works fine on my long axis where the stress and load is not as heavy. I have seen deflection on the v-groove bearings on the angle iron if there are any lateral loads. This will be a redesign in the very near future. The angle iron was a less expensive solution on the long axis for my linear motion.
@@OldGuyWoodworks so linear guide rails for the z axis
