Meet the eShapeoko #344

Post by tiltit » Sat May 16, 2015 8:34 am

Hello all, first post here but I’ve been reading the forum quite a bit and it has been a great source of information and help.
So here is the current state of my eShapeoko that I’ve had for at least over a month if not two.

I have quite a few copper clad board lying around so I used some of it to customize the machine.

I also had some really old limit switches so I did not order any. Unfortunately the spacing of the holes on my switches was larger than the ones through the motor plates, so I figured a temporary solution out.

The limit switches are still causing me a lot of trouble due to false triggers. I usually disable then before cutting.

The Z limit switch was also a bit of a challenge but I managed to install a single one for homing.

And here is one of my first projects with the eShapeoko. An acrylic case for my nixie clock.

That's very clean milling in acrylic. Good looking clock, too.

The limit switch holes are for the next smaller size of microswitch. I'm not sure you've seen it, but I also designed a bracket for the Z limit switches, so you can have two of them easily.

You seem to have done some milling already. How is that Proxxon holding up?

Thank you Catalin, It was not easy to cut, I had to stop the acrylic from building up on the end mill using a small piece of wood. I ended using at least twice as much material than would normally be necessary.
Concerning the limit switches I probably will get some new ones and also a bracket. Is there any reason for having 2 limit switches on the Z axis? I think the machine would crash way before the switch triggers.
How is that Proxxon holding up?
I don't have any experience with anything but the Proxxon rotary tool but it seems adequate, tho I do wish to upgrade it for something like a Kress spindle, if only to be able to use larger end mills.

So far the machine has been running nicely, I am really happy with it. Lots of fun. Thanks.

Most excellent Nixie clock!!!
I have built the guts for mine, and it is working well, but it's all just wires n tubes just waiting for a case. I just have a list of projects I am working through and the clock is deep in there. Congratulations. You have to feel good about that.

Did you program from scratch? I have a thing for making things far too difficult and decided to program from nothing. It's Arduino based and was not as hard as I though it might be, but I still have a couple of kinks to work out as it is loosing time.
How many buttons did you use for setting time n such?

Thanks, I also have a list projects and I have been working on the clock on and off for way too long and it is still not really finished. I very rarely manage to bring a project to an end, but really want to finish this one. There are two buttons on the clock and one switch. The buttons could be labelled "Enter" and "Select" and the switch is to enable and disable the alarm. The clock is very inspired from Adafruits Ice Tube Clock. It counts the time in a similar way by connecting a watch crystal to the atmega and having timer2 using it, the microcontroller core runs off the internal 8MHz oscillator. Also the high voltage is generated with a PWM output and a voltage divider is used the detect loss of power.
I just setup a github repo if you are interested in seeing the code. It is still unfinished and in my opinion messy and hard to read.

Well, my proxxon ibs/e has given up on me :(. It still works but produces the most unbearable screeching sound. I have been cutting a lot of hard wood lately.
I just wanted to let people know that the proxxon is in my opinion not the best choice for a cnc. No point in having to replace the spindle every 4 month...

Your brushes may be gone. If that's the case, stop using the spindle and replace them. The brushes are considered consumable with this type of electric motor.

I now have a Kress 1050, and it is night and day compared to the Proxxon.
I have been cutting aluminium for the last two days and created a little add-on for wire management to my eShapeoko. It's a thin plate of aluminium that fits on top of the X carriage.

Here are some pics.

I am having so much fun with this machine, thank you cvoinescu for making it easily available in Europe.

That's a cleanly milled piece of aluminium -- nice. And you're welcome -- glad you like it. :)
