Re: Hold Down Design

If that became a problem I could always run a short screw through the stretchers into the material. There isn't a lot of pressure required to hold the material since there's a lot of surface area contact creating friction along the sides. Also, the pressure on the delrin stretcher side is concentrat...

Re: Hold Down Design

With what testing I've done, I haven't had any problems with it pulling up. I haven't had a need to do any deep cuts however and I'm probably going to move to a DW660 next week. I'll see how it works with the new spindle and update this thread with any further information. Considering I can pick the...

Hold Down Design

I took a page from the guy who made the hold downs with Harbor Freight wood clamps and put together this idea. WP_20140606_17_44_46_Pro (Medium).jpg A friend of mine that works in a cabinet shop gave me three pieces of, what I think is, inch thick Delrin. I made two blocks to guide some 3/8" all thr...

Re: Spindle Control

This didn't work as expected. If I'm connecting to the Arduino/GRBLShield it doesn't issue the M3 until I do a soft reset which means it's going to turn on the spindle. I didn't have a lot of time last night to look at it so I'm going to play with it some more.

Re: Spindle Control

Tom, I didn't see your reply before my last comment. This might work. It would effectively interchange M3 (start spindle) and M5 (stop spindle) since that's the way the logic works with my electronics anyway. When the e-stop is triggered there won't be any voltage on the arduino side so the relay op...

Re: Spindle Control

The problem with that solution is when the Arduino is powered down, the relay is closed and the outlet is hot. Hitting the e-stop wouldn't shut off the spindle in that configuration unless I wired the spindle power through the e-stop with the arduino power wouldn it? That opens the chance for proble...

Spindle Control

Is there a way to change the spindle control so that it is on when you power on the arduino? I understand that the relay I'm using (or is it the Arduino) uses the opposite logic I need for spindle control and I can turn it off/on with M3/M5 but I can't quiet wrap my head around how to Invert the sig...

Re: Re-working the Shapeoko 2

Well, that pours cold water on my warm enthusiasm. I'm running less than a meter so that side should be OK going 23AWG CAT6 to 26AWG into the motors. The modular connectors seemed to be working while I was testing last night but it wasn't under a load. They're rated at 1.5A max. I'm not really inter...

Re: Re-working the Shapeoko 2

I found this to use as a pendant. Small, wireless, versatile and hopefully customizable. I want that little House button to home the machine!

Re-working the Shapeoko 2

Now that I've had a few months with the Shapeoko 2 I decided I needed to review, reorganize and otherwise rework the way I was connected. I liked my original joystick / arcade button controls but the enclosure had to be way too large for the space. I had found this cool Partargas cigar box a while b...
