New XYZ Gantry Kit

[louieatienza]

Nice machine; your daughter is a lucky girl! Good luck to her and her endeavors!

Am I the only one who noticed that nice metallic red machine is a good match for your metallic red truck?

It looks great, and it's interesting to see how they solved one the the design issues with the moving gantry with that very simple dual rack resign and motors on the gantry legs. Cool.

Can you show a close up of the bottom V bearing assembly? It looks to have white wipers and I'm curious how they set up the wipers and bearing blocks etc.

Roman,

I could be wrong, but the blue things look like machined motor mounts. The motors would mount onto the square flange on the outboard ends. There would be a coupling inside and an access hole in the round body.

My question would be if the mounts are fixed in place on the vertical riser plate, or do they have a tension spring?

On their website there are motors on the blue thingies. Not much other details to be seen though.

Interesting as to how they integrated V rollers into extrusion construction machines.

I love the V-bearing extrusion & the Uniguide Z axis. Sounds like this company worked with robotics & extrusions and decided they had all the tools to build a CNC so they did it.

If I had to pick one thing about the design I don't like is the arms for the gantry. I noticed in their actual video with a working prototype they did not use those arms.

I'm assuming that the ganty uprights are machined aluminum, is that correct? At any rate, looks very nice.
It would be nice to see more women in this male dominted field of CNC. I've worked with some women, and I love that most (if not all) have an extreme attention to detail.

Roman,
I will try to get a good picture of the bearing and wipers.
LOL on the color match. I saw that when I posted the pictures.

The Blue things are 10:1 reduction drives. The motor mounts are the un-anodized hunks or Alum.

The mounts for the bearings are adjusted with set screws and cams. I will get some pictures.

I am interested Ross what you don't like with the gantry arms? The are rather large and sort of required with all the bits they have for the bearing adjustments.

Yes attention to detail is important. Heather was telling me today that she does not have "anal about things" like some people in her class. But she make up for that in production. I figure she could spend more time in the details. Anyway she came home all excited today after her first job interview for her Co-op term. She was offered a job and accepted and a real interesting place. She went in thinking it might not be a place to work but they wowed her. Was offered job on the spot.

They also have adjustments to I assume dial in the gear box to rack position

Ahah. 10:1 reducers. That makes sense, with the pinion being maybe 3.5" circumference that's a lead of about 3 turns per inch.

The ohter axis leadscrew looks single start, about 5 turns per inch.

Thanks for posting the pictures and overall it looks like a pretty good setup.

Waiting for bits from 80/20 to arrive before much mores is going to happen. Love the 80/20 stuff but hate the round about to order it in BC. Seems you have to go through a distributor. I thought a distributor would have stock, have product expertise and have an economical method of shipping.
With any luck early May I will be able to start bolting the base together. :-(

Finally some progress
Got the base bolted together yesterday and got the unit assembled.


Here is an overall view with my messy shop in the background.




Some more details of how the units bolts to the base. The base is made out of 80/20 40 series extrusion. My only observation is the base will have to bolted to the floor. If I were to do it again base unit would be longer and extend in front and behind unit to prevent tipping.


Here is a picture of base with the rails mounted.



Everything fits nicely and manual is pretty good for a first pass.

Next step is to mount up the steppers and electronics and go through the alignment process add limit switches etc then tackle the spindle.

Any luck getting the electronics installed? It is fun watching your build move along.
