I've found that my Carve King will not damage itself if I accidentally run any of its axes into their stops. With its more powerful motors, can the Mega V damage itself?

The T plate table itself is not structural. There is joining rail under the bed. It won't matter much to the rigidity of the machine whether or not you have the MDF bed or the aluminum T plate bed.

It is possible in theory I suppose, but unlikely. We have crashed dual driver Power Routes (over 1000 in oz of total torque) and nothing was hurt. Running I to the end at full rapid (over 600 inches a minute) wouldn't be ideal, but it usually takes a lot more to break these components.

I'm rereading things and thought I'd ask a couple more questions.
1. Just to confirm shipping is additional for the router kit. (nice work on figuring out cost reduction on lift gate service for residential on plasma table) 2. With the T-Slot table, what is the total workable material height? I think I'd need at least 3" for my application, without a spoil board. But maybe if spoil board + 3" doesn't work I stick with a MDF table instead of T-Slot, though I anticipate doing a bit of fixturing which would work well on T-Slot. 3. Can you say more about the Router XYZ touch plate? 4. Do all parts comes tapped and ready to just assemble? Torque wrench? Or maybe another question is are typical hand tools enough to assemble the router kit? 5. Does the rack/pinion need some protection from debris getting in it? I imagine there is a lot of force and at the same time I wouldn't want to mess up those critical parts. 6. Where are the limit switches mounted? I didn't notice them in the posted videos. 7. I've been using OctoPrint with my 3D printer. Have you tried an RPI + software to make a web interface so I don't have to tether my laptop? Any recommendations?
I saw a YouTube ad for this, very nice. Hopefully that campaign has been good at getting awareness and traffic. Costly?

Thank you @bruce, I've got some googling to do to learn more. I recognize Chilipepper from some past searching and will have to look into the others as well.

FYI: From a safety stand point running a CNC without direct supervision is not recommended.

I saw a YouTube ad for this, very nice. Hopefully that campaign has been good at getting awareness and traffic. Costly? 1) Yes, it will be. 2) With a thin spoil board you'll be able to work 3". The T bed is actually a little thinner than the MDF, by about 1/8" 3) It is an a block of aluminum that has an "L" shape along the outside of one face so you can probe the edges (X and Y) in addition to just a Z probe. 4) Typical hand tools will be enough to assemble it. 5) No, not really. It is not as sensitive as you might think. Our production router has rack and pinion and we just clean it off every now and then. 6) They aren't installed there. Production will have the X switch at the top of the gantry rail on the left side with a roller switch that engages against the X motor mount. Y will be on back of the left Y rail and engage the left Y motor mount with a roller switch. Z switch will get mounted to the back of the X plate and a stud riding on the Z will engage it. 7) Like Bruce mentioned, we discourage unattended operation. As it comes, it will be set up as a tethered device. Please let me know if you have any other questions.

Thank you Derek and Bruce.
I hear you on unattended operation. I prefer to have my MBP laptop available for designing rather than attached to a machine doing a job that a RPi can do just fine (serving GCODE).

Will this new machine be able to engrave carbon steel?

We do not advertise any of our machines for mechanically cutting steel. It could probably do it because we've done it with the Carve King and the Carve King isn't as stout as the Mega V, but it is just not a material that we are claim to be supported.

Can I order a second router "clamp" for the Mega V so that after assembly I have dual clamps like those offered as an option on the Power Route? Or is the stiffness of a single router clamp adequate because other flexing in the Mega V limits the cutting accuracy under load?

We aren't planning for that at this time.

One week to go! Yahoo. Boy I'm excited and trying to get the budget around. I hope your preparations are going well Derek.
Yesterday I caught a video by Robert Cowan and machining aluminum. I liked his straight forward style to teach and explain. It made me think that I'd love to see some videos of Mega V cutting different materials and understanding feed/speed and performance.
Here is the video

Yup, one week to go!
That certainly is a nice video. We are making an effort here to improve on content creation so we'll perhaps make some like this.
Preparations are going well. We've already made hundreds of certain parts from materials that we already stock to put us ahead of the curve.
