This is just kitchen table so far. Bipolar parallel with a 270K resistor just to get things moving. The motors didnt evan get warm at all so when i ran a 25 min g-code test run. There was a slight temp change but not more than if your hand was in the shade and moved into direct sun light on a 65 degree day I would say. So Ill will ramp it up to 330K then to 470K when the table is built...which is next. I had to ditch the On/Off push button, I rewired that put 4 times(per time plans) and it fired the On switch side each time.???.

If it possible to edit the #46 entry on this build thread it is wired incorrectly! My fault. The A1/A2 coil are on the top(left side of contactor in picture) not the side.

Jason, just post the correct info and someone can fix the other post for you. :)

Table is standing. Working on the rail drilling and placement.

Is the only thing holding the rack on the X rail is 3M tape and the 2 end bolts?

Jas

The other question is the height of the X rail with a V cap. Im using steel angle 2x2.5. Can I keep the height of 2 inches to place the V cap on?, avoiding half to cut a 10' long 1 inch peice on the 2" height off? Im concerned about the distance between the Top of the V cap and the where the rack and pinion meet if I keep the 2" height.?.

Jas

Yes, and it is plenty.

You must keep the height according to the plans if you want the system to work, otherwise you will have to adjust numerous other parts to accept the higher rail height.

I think you will run into problems with the motor/pinion union (i.e. the motor brackets won't let the motor pivot low enough to reach under a 2"+ high rail).
The rail cutting to height is not hard. Just look at the various jigs people have built for this. And use thin cutting disks.

Table is assembled, X rail for Vcap cut to proper height. I will get some pics rolling soon.

Rail Caps
 

I bought rail Caps and now wish I hadn't. The grinding isn't all that bad and you replace that task with drilling and tapping holes. I would rather grind. Want to buy some rails? Don't use 1/4-20 screws they are to big.

My machine has well over 200 hrs. with only 3M tape bought at Autozone holding it on. No bolts, no welds. Just tape.
