Monsters Machine - Saturn 4X4

[MonsterRobotics]

Just received word from Nate that our machine is on it's way and we are scrambling to get the garage ready. The machine stand is going to look a lot like Caveman Carver using wood and MDF sheeting. Don't have 220V service (yet) so the plan is to start with a PORTER-CABLE 7518. Are the 7518 mounts available for the Saturn? Looking over Nate's website, I cannot find a mount.

I don't have them in stock at the moment. I will soon. You should be able to order one from CRP (Porter Cable 7518 Router Mount - CRP142-00-08 | CNCRouterParts). You don't need the base adapter.

I was originally planning on using my Porter Cable 7518 router on my new Saturn but recently decided to switch to a spindle so I have a brand new un-used Porter Cable mount I can sell you. I purchased it from Nate at Fineline when I bought my machine so it is ready to go. If you want it I will give it to you for 85 plus shipping, which is 10 less than the going rate. You will have your new Porter Cable mount and save 10 bucks in the process, I won't have to bother Nate with a return...everybody wins. Send me a Private Message if you would like to go that route.

Looking forward to checking out your new machine setup.

Thank you for the offer but after I spoke to Nate I went ahead and ordered one from RouterParts

Even before hearing from FLA that the machine was on its way, we had started a design of the bench. Our inspiration started with Cavemancarver's bench using wood/MDF.


Construction started with the 'ends'


Tied together with 'stringers' - almost all the wood was 2X6 or 2X8


According to the model the final weight for the stand is about 500 lb (we didn't actually weigh it!)

Great advice from others in the FLA to use a cherry picker - we actually had one but didn't realize it was capable (until we tried it!)


Dropped it on the stand yesterday


So, it's been a busy week and a great way to end the year - Happy 2017 !

Very nice. Wonderful job on the stand.

Looks great! Why the extra room around the perimeter? Just curious; I don't have the room to have any extra around my 2x4 so my stand is the exact same footprint as the machine frame.

[MonsterRobotics]

The machine is not shown 'centered' on the table so it looks like a little more room than intended. But the table is definitely a bit larger than necessary - did it cause we could I guess.

OK...I guess I'll just send it back to Nate then.

Z-Axis motor (NEMA 34) mount problem - same issue as sybilsurf

We used longer 10-32 Allen Head Cap Screws to offset the 1/2 inch.

[difalkner]

That's the same issue I had, as well. It seems the mount is designed for NEMA 23 but we all seem to be using NEMA 34 motors. A machine of this caliber and heft deserves NEMA 34! LOL!

[MonsterRobotics]

Agree we need a better design option for mounting the larger motors on the Z-Axis.

X and Y are well thought out and it seems like we're missing something for the NEMA-34 Z-axis installation.

Even if the stack-up worked with respect to the lead screw coupling it looked like one of the socket head cap screws would foul the motor installation pilot.


Initially it seems like the coupling is the problem...



But this screw would have to go even if the stack-up wasn't an issue.

[sybilsurf]

I was considering using aluminum stand-offs first, but then I saw I had a piece of 1/2" X 3/4" aluminum in a drawer.

That middle cap screw didn't interfere with the motor in my case, it was still below the motor.

[MonsterRobotics]

Yeah, looking closer at your installation it's obvious the motor pilots as intended - hmmmm

[FineLineAuto]

I am working on a fix and have a new part out for manufacturing. I will be sure to update all existing machines with the new part as I get them. Thanks for your patience and suggestions for this.

Relocated Y-Axis limit sensors similar to difalkner and sybilsurf

Relocated Y-Axis limit sensors similar to difalkner and sybilsurf

Fun stuff to drill - right!!

[MonsterRobotics]

Yeah, drilling the frame was fun....

Fortunataly, the crosshead stops are aluminum.
We located the sensor on the center line of the upper rubber stop and remounted the bumper half way between the original bumper and the sensor.
Works great!
Still working on the Z axis

[difalkner]

Looks good! I didn't use a Z- sensor because mine are straight and not right angle; they stick down too far.

[beltramidave]

Wouldn't think you would want the Z sensor sticking down like that. Way too much potential to hit something. Most machines do not even use this sensor, just set up the soft limits.
