Troy,

The correct way would be figuring the centre of gravity of the head and anchor it there, I think.

Regarding vibration dampening, this should not be a factor to be considered as the chain cannot transfer any substantial vibrations. The vibrations will be dampened by the head mass and also transferred to the column and base via the linear slides and thus it's important to have well preloaded linear blocks.

Someone else will have to address the plugin question as I am not an expert. What I do know is that Mach3's data transfer rate is 10Hz indeed, like you said.

The screen refresh rate is fixed and doesn't depend on the engine frequency as far as I know.

LOL... I was trying to keep this conversion as simple as I could, but somehow I keep adding more "features" to it, and now you're suggesting throwing in a PLC as well... no thanks Wink

Dan

P.S.
Sorry, forgot that simple for you means using a PLC in the first place Cheesy

Hood,

Yes, you understood exactly what I was asking Smiley So both the supply and control are 24V. Thanks.

Dan

Thanks Russ.

Hood, probably for you: in the first photo, the header on the left looks like the 24VDC supply, and the one on the right looks like the control. What would the control be? Will it work with 5V?

Hey, Russ, thanks for that!

You are without a doubt in the avant-garde, Hood!

Thanks for the link!

Hood,

So the Scorpion works with Mach3? With the Scorpion you are using one network card, what did you need the second one for? Do you have your PC connected to a network?

Where are you getting those panel buttons from?

Dan

Hood,

It looks good! And certainly each machine you do gets better Smiley

A few questions:

I know a Smooth Stepper must be in there, but can't see it...?

Also, since you have all those buttons and particularly the FRO and SRO pots, I would assume a Pokeys should be in there, but can't see that one either.

Could you explain what are the buttons on the first raw at the top? SpinEn looks like enabling the spindle drive, but I would expect a On/Off switch and this looks like a momentary switch? And the other two, just curious what are they (Limit and Control)?

Oh... and does Russ sell those relay boards? Where can I acquire one?

Roger,

While making a worm wheel with a tap like some do will transfer the movement, it shouldn't be considered for efficiency critical or, more importantly, for high load transmission applications. The tooth profile is not thick enough to carry high loads and the helix would be probably too small leading to reduced efficiency. There are many other considerations as well to this.
