C-Beam Machine - MyFirstCNC

Discussion in 'CNC Mills/Routers' started by Paul Stoller, Apr 1, 2016.

This is my first foray into CNC machines, after much review I decided on the C-Beam machine as it seemed easy to work with and will enabled me to build more and larger machines as I gain knowledge. I am planning on building the machine largely unmodified from the reference design. I will be building the machine an axis at a time as I need to spread out costs over time.

    Here is how I have it hooked up now. I'm not sure what I'm missing.

    I see from the pic that I need to tighten up the blue wire, but it shows good continuity.

    Hello Paul, I could be wrong here but look at the video

    (Kyo)
    I believe he is a member here but according to his hook up the enable negative is not to be wired up. Just an observation.. Cheers

    Leaving the wires on the protoneer hat as you have them in the above image.

    Yellow - Direction
    Red to Step
    Blue to Enable
    Black to Ground

    Driver side connection should be as follows.

    Yellow to DIR +
    Red to PUL +
    Blue to ENBL +
    Black to DIR - and jumped to PUL -

    ENBL - on the driver should be left disconnected.

    edit: busybuilder types faster then I do lol . Yeah my video shows how I have my drivers wired up. Currently running grbl 1.1

    Okay, Thanks for the input everyone, that took care of it, I guess I stared at this too long as I didn't notice I had the step and direction pins reversed at all. Now just to switch the wiring on the other axes and to test them out.

    I just got done switching the wiring for each axis and tested each of the four cables and all appear to be working correctly now. Thanks again to Rick, busybuilder, and Kyo. It really nice to have a second+ set of eyes to catch things. Now just to put everything back together and see if it all still works :)

    Thanks Kyo, after I finish tidying up the wiring as much as possible I'm going to go back over the mechanicals (double checking everything is tightened properly and square). And then I'll be able to hook up the steppers to the machine. It won't be long before I'll be able to cut something, now I just need to get started on the sound proof enclosure to keep the neighbors at bay.

    That being said I do still need to buy tooling and a router/spindle.

    I'm still going back and forth on to go with the DeWalt or a Chinese spindle. I know I would really like to have the speed control and once you add in super pid to the DeWalt it's just about as much money.

    Even though I hate waiting, the bonus of needing to build the enclosure, and wait on the spindle/router, is that I should be able to get the machine itself fairly dialed in before I get to cutting much.

    Spindle will be a lot quieter then the dewalt and you can controll the speed of spindle with a pot. or some controll boards do have controlls for spindle so you can run it from mach 3

    Well I’ve gotten everything physically ready to cut and I know everything moves properly, but I need to go through the configuration for grbl/bcnc. Does anyone know of a food walkthrough of this for a raspberry pi?

    Can someone please help me! I built my C-Beam about a year ago and I'm having the hardest time trying to get it to work properly. I am trying to use Grbl panel release 1.0.3.0 with Fusion 360. I have an Arduino uno with a V3 shield. The problem I'm having is in trying to cut a simple pocket, 1" dia x 1/8" deep with maltible depth of cuts. The first cut looks great but when the bit retracts and moves over to start the second depth of cut it rapidly plunges into the part and at other times it will start the second cut in a new location. I have checked the code and the code appears to be correct. I have a 2.2 kw spindle with a cutting speed of 15,000 rpm and feed of 20 inches per minute and entry speed of 8 inches per minute. I am at a loss and ready to give up again.

    I’m still learning here myself, I’ve not yet run into any issues like you are describing but I’m still on .9 version of grbl. I hope someone is able to point you in the right direction.

    Thanks Paul. Metalguru put me right on the problem. It looks like I just needed to shield my spindle cable. once I did that it seems to be working fine. I'll run some more test and recalibrate all axis in the morning.

    Hey I know this is super old but what shim/sleve are you using with that router...I have a spindle that looks the same diameter and I am having the hardest time with this and the build
