I need a specizied fertilizer system for our farming operation so using CamBam I build metering systems that could be used with a air blower system. Except fofr the pipe bearing and a few minor parts every thing in the PDF was built using CamBam.
In the photos you can see the mettering units under the stainless hopper.

Somewhat goofy bits, but these are the first items off the Tree VMC fed by CamBam. Have the tool changer figured out now, too. The next few weeks should be interesting!

I catch fish with Cam Bam.

A fish story with pictures - now that's one I can believe!

Hi Bob just a wild guess but I think you might like fishing, all I can say is you must have more patience then me.
Well done its important to post to show others.

Hi Bob,
I already know about this, just wanted to congratulate you on this forum too.

I just posted this work holding vice jig tonight.

All stuff I made is done in CAMBAM. http://2.bp.blogspot.com/-M4WSsWBZA0...0/DSCF2600.JPG

Nice looking wood machine. I bet its more rigid than some the cheap chinese aluminum machines out there. Why did you decided to go with a moving table instead of a moving gantry? Same thing? Sacrifice some working envelope to make the machine stiffer?

Hi,
Thanks, it is was designed mainly for stiffness. I used there Tr 14x4 (it is ACME thread 14 mm diameter and 4 mm pitch) and only 0.8 Nm motors. It is not very fast. So I decide to put relative small feed (1m /min) and try to achieve biggest stiffness that can be achieve in that kind of construction. Result is quite good for me :)

MaxNC Bearign Mod
I had retired it but it bugs me sitting there on the shelf unused. I decided to add captive bearings to the X & Y lead screws. I don't have a clue how to get everything lined to cut a fixed one piece bearing carrier so I went with a two piece adjustable design. One end of the screw will continue to be supported by the stepper motor, but the other will be supported by a captive double bearing. With a spacer between the bearings it should eliminate almost all backlash. (I already retrofit acetal antibacklash nuts a while back).
There were multiple problems. First I had to figure out how to fix the bearings to the tiny little 1/4" acme lead screws. I made a "mandrel" type piece for each lead screw. They were turned to 1/2" (the size of the bearing bore) threaded on one end for a nut, and drilled out threw the center and tapped to 1/4 16 Acme. Then I drilled and tapped the collar for two 6-32 set screws. In theory I can adjust the working length of the lead screw to optimum by threading these on or off the lead, then when I have it right just tighten the set screws.
Then I had to make a bearing carrier. I went with a two piece one. The back piece can be adjust left to right, and the front piece which holds the bearings can be adjusted up and down.
Ultimately I shoould be able to crank the table up close to the fixed bearing and snug up all the screws in order to position the bearing very close to center of the lead screw axis. Maybe I'll assemble it all tomorrow, but I still have to cut one more front piece. Of course X & Y are both different so every piece is unique. To make it more interesting the front part of the bearing carrier has to cover the screws for the back piece. Hopefully I can get close and then just slide the table forward to get to the back screws.
Three of the four bearing carrier parts were made in CamBam. The 4th part will also be when I get to it. Fortunately all I should have to do to design the last piece is make the base level wider and move the mounting screw slots out to match the threaded holes in its matching base.
The mandrel/shaft adaptor was done by hand and on my manual lathe.
