Build Log for #6971

[AlBorland]

The size isn't critical, mine are around 20 x 8 x 6.3 mm and I have mounted them between the plate and makerslide (screws cut into the microswitch plastic, no nuts). Only the cable attachment is not good, would be a lot nicer if there was an additional hole in the plates for that.



On the X axis, I had to install a simple endstop (just a screw + nut in the makerslide slot). On the Y axis I could directly use the endplate because I don't use the standard belt clamps.

I think "subminiature" switches (also known as "V4") work best with the slots. Ultra-miniature will work too, especially if they have levers, but the slot is a bit wide for the M2 screws that fit those.

Process in the works for an electronics upgrade to our shapeoko 2. I have ordered a C10 breakout board from CNC4U and some Pololu DRV8825 drivers. Going get an old Desktop PC I have laying around loaded up with Linux and LinuxCNC. Looking forward to putting this all together. I am building an enclosure box to house all of my PSUs and electronics.

Ok latest update is Building out Drivers. Getting ready to run on a C10 Break out board which I am still waiting on getting here. Drivers are DRV8825 from Pololu. Going to try out LinuxCNC.
(Edit: As Mentioned. DO NOT forget to put the Cap in Parrallel on the 24V Input) Added in my Wiring Diagram

Your drawing does not include the capacitor on the motor supply (but I see there is one in the actual boards). That capacitor is essential. Without it, turning the supply on or off can burn out the drivers (due to LC ringing -- it's explained on the Pololu page).

Yeah I know. It slipped my mind to put it in the drawing was just to help me as a template putting them together Mostly as a grid as to where my wires were going. Caps are all in place as you can see in the actual Board.

Just mentioning it in case someone else wants to copy what you did.

Updated just incase..... Thanks. Just so darn much stuff to try and remember.

Got my Brackets cut out for the new drivers.

Ok so just placed my order for the parts to expand to 1000x1800. This is going to be very interesting. Cant wait.
