Started building my first (Joe's) router

Awesome pics David, like the controller. What's the multifunction card for besides "the obvious"? Was it hard to wire the eswitch in, does the xylotex kit include a place to wire it in on the board? I know how to set it up in mach3 but was wondering.. what do you plan to make the eswitch do, just turn off the router and electronics or have it raise up to the home position? Is your router spindle going to be turned on manually every time or do you plan to hook it into the electronics? thanks!

The eswitch is not yet wired, but is easy to wire, it just connects to 2 of the connectors on the multifunction card as do the limit switches and the enable switch.

I beleive you can use the Xylotex board to connect it as the provide terminals on the card for the unused parallel port lines, but by doing everything through the multifunction card it gives you the benefit of optoisolation from the PC.

The E-stop will (and I believe should) just stop the router and electronics as I don't want the machine moving if I hit the estop in case I am hitting it because I am all caught up in the machine

My router will be hooked into the multifunction card which has a solid state relay built into it. You can see details of the card here http://www.cnc4pc.com/Multifunction_CNC_Board.htmhttp://www.cnc4pc.com/Multifunction_CNC_Board.htm

Thanks for the info David. I will do some research. I know I want an e-switch, it's a diy hobby machine, but it's still serious non-forgiving machinery. I like how you combined it in one tower, it's clean that way, less wires everywhere .. where did you get the e-switch/function buttons from? Thanks for your info, it's very helpful for my upcoming build of joes.

The E-Switch I ordered from IMService http://www.cadcamcadcam.com/index.as...PROD&ProdID=60http://www.cadcamcadcam.com/index.as...PROD&ProdID=60
They use to have a large and small one (just different size button) but now just have the small one. I will probably order the small one and swap it with the one on the PC and put the large one on the router itself.

The on/off and enabble button I got from mouser.com (part number 611-DA102J4RS215QF7).

Nice controllor setup, I like the all in one case. is that a 24v PSU for the controllors?

I would also make sure the wireing is isolated to areas and shielded as not to get any interfierence from electronics.

[David Da Costa]

Hi Joe, yes, if you the mean the one under the cdrom it's the one that came with my Xylotex kit.

Yes once I get everything in it's final place, I will try to keep the wiring as far away from interference sources as possible. Of course that is the risk of an all in one setup.

Worst case I have a separate box that I will just re-install the controller stuff into if I find I am having any interference issues.

Any recommendations on shielding?

just use shielded wireing, also lateron you may want to beef up the power supply. run it a while with the 24v and see how it performs, I use 36vdc with 200oz motors and works good. 80ipm is what i cut at mostly.

joe did you buy the kit from xylotex or just the components?

[David Da Costa]

bp092, I believe that Joe used HobbyCNC kit not Xylotex.

sorry I meant you lol, long day, long day of work and everything, minds in two different places

none of the above, I got the HobbyCNC 3 axis kit, 36v 10a power supply, 200oz motors, and cuts at 80ipm with no problems, I have been running that kit for a year now.
