Re: Limit Switches

Alright, that's good to know. I don't know much about programming or writing code. What I would like to do is wire up the two switches like you have them in your video. For the z axis I'll make my own switch that consists of a wire attached to endmill (just momentarily for homing purposes) and a met...

Re: Limit Switches

Thanks, that's really helpful, so really all I would have to do is copy and paste your code? Also, are you only using 3 switches (2 in the video)? What is the sequence of movement for the axis'? like in your video it looks like both the y and x move until they stop, is there a way to make it so say ...

Re: Limit Switches

I'm looking to do this too. I was wondering if you could maybe write some steps on how to edit the Grbl code to accept these switches. Also, are these N/O switches or N/C? Sorry if that's a dumb question. Thanks, Michael

Re: 3d printer upgrade

That set up will work fine, provided you have an arduino Mega. I don't really know much about the grbleshield, but I'm pretty sure you can't use it for 3d printing as it doesn't have a 4th axis option to attach the extruder to. You may want to look into these electronics. http://www.ebay.com/itm/140...

Re: Work table designs

You would be able to get most of the cutting area done by means of g-code, otherwise you'd probably have to do sections or just finish it off by hand. As far as an "end mill" goes, here is a 1/4" router bit, I have personally order from these guys and they are very quick (not affiliated with them at...

Re: My Electronics Work

Hi, first of all, very nice and neat enclosure! I'm in the process of making mine and I was wondering if you could get a close up shot on how the power switch is connect to the power supply, that would be great. Thanks, Michael.

Re: Work table designs

What you could do though is just mount the v-slot router bit onto your spindle and create g-code to cut it out for you. That way all you have to do is replace the spoil board, (which you would be doing with your method) and then run some g-code and you're done. Plus with that method, your slots will...

Re: Work table designs

Instead of T-tracks, you could always route a t slot into an MDF base, although this is similar to the v slots, but at least this way you don't run the chance of destroying your endmill by hitting the aluminum.

Re: Assembly done, test speed is awesome!

Very impressive! Just checking, are these stepper motors the 400 steps/rev available from sparkfun? Do you have videos of it actually cutting material? I'm assuming you will be slowing it down when you do cut? Thanks, Michael

Re: Dual Gantry

While it's a neat idea, I don't think it would be practical being as you can only run one "machine" at a time. I think it would be more cost effective to have different interchangeable heads that you can mount to the z axis instead of having dedicated machines.
