Hi all,

Finally, I am back again to work in the machine, so I taught I would share some of the advancement.


--> I found a solution for the previous problem of the damaging that was happening to the V-groove wheels bearings. As it turned out that this was due to fabrication tolerance. In fact no matter how careful is the method of the insertion of the bearing, once it is inserted it stops turning smoothly. So i grinded the inside of the wheel a little bit with a Dremel tool using a sanding bit. Then I applied some Loctite glue and the problem was gone.


-> I redid one of the X rails as it was a little bit out of tolerance. For that, i bought a melamine white panel as Guille and Mike adviced in previous posts.

--> transferred the holes from the old rail to the new one.

--> I also welded the Y-car.

I have now a rolling X and Y axis. Here you go a link to a video showing the advancement

Best regards.

And here are some pictures :

Rack attached to rail

Hi

Some progress

- The Y rail rack is attached
- X rails racks in pgrogress

I also ordered the following :

- 2 x Clearpath Servos CPM-SDSK-2310S-RQN for the X-axis
- 4 x 5:1 Timing belt reduction Kits
- 1 x Acorn Centroid Controler

Waiting for these orders to arrive, I will work on CAD for the Servos plates adaptation (NEMA 23 version). I will post some pictures for the CAD solution once completed for criticism.

Best regards.

Looking great! I was too scared to mount my racks to the rails off of the table. I had to rig up a clamping system to get them close then slowly stick them on with the rails already mounted on the table. That 3M tape doesnt mess around! Keep up the good work.

Thanks a lot Ted . It is indeed a scary process.
I didn't find the 3M tape hear in Morocco. I found one of BISON that i will try as a replacement. Link :

Some other updates :
- The package containing the Acorn controller has arrived to Morocco and it is now blocked in the airport because I must find a way to clear the customs declarations.

- As for the Servos they are still in transit

- The Timing belt are still not shipped from china

Best regards
