Definately a scrapyard challenge

[motoxy]

AAARRGGHHHH I HATE COMPUTERS. All ready to do some alignment checking and the computer decided to crash and reboot. Thats all it does now is reboot, crash, reboot, crash...... Tried a linux disc but that would not load either. It has always been a bit suspect as it would happily run mach but not cambam. Here are a couple of pics. Wiring still waiting to for a tidy up.

Thought you might like to meet my assistant. He seems to have moved into the workshop. I have evicted him but he comes back. I am hoping to train him to weld.

Looking good. Did you solve the suspected problem with the ballnut? If you've not already, try turning the ballscrews by hand to see if they feel smooth with no cyclical torque variation.

I think he'd be more suited to pop-ribbeting?

HA! Told him that and he laughed.

Got a new ballnut from cnc4you and all the horrible noises have gone. I am so close to finishing but there is always just one more little thing....
The tray on the back is for the drag chain. Then the cables and tubes will be sorted.

Well done keep up the good work.

Limit, homing switches in place and both drag chains. Trying to connect the touch off plate but so far to no avail. All thats really left to do is connect the spindle. Tried the water pump I had and it was useless so its off to ebay. Promise a picture next time I am in the workshop.

Runs beautifully at 2000 mm/min on the x but any more and it sounds yuck and at 2500 it seizes. Tweaked alot so just have to keep looking. I suspect that the old drill press, chopsaw, handtools build suffers a bit from lack of precision so when I am cutting I will try to fabricate the more essential parts to a higher standard.


Nearly there!!

Bruce 2mtr/min is more than enough for cutting Ali to upgrade so don't fret mate.

You'll be amazed how much more you'll eck out the thing with a bit of shimming and tweaking.

What's with the plate.? What's it doing or not doing.? How you connecting it.?

[motoxy]

connected it to input pin 13 (i think ) and then thought how does this work. Chatted to Michael and it acts by earthing. Touched it to earth nothing. Somehow I think I have it a bit screwed up. So I stopped until I could find an article or post to clarify.

First have you enabled and set the Probe Inputs in Mach to pin 13.?
If so then just take a wire from any of the Negative pins of the BOB and touch to wire coming from pin 13 then it should work. Check the diagnostics screen input signals state ad the digitize pin should light.

If on all time without wires touched then flip pin 13's active low setting. Then it should work has expected.?

[motoxy]

Still not managed to get the probe working but BIG news. I have a video of the first proper cuts.

Thanks guys for all your help....and the help that is still to come.

The m/c is a bit wobbly because I have it up on castors to move it about as I work onit. Once finished it will be wedged up.

A very happy Bruce

Nice one! I can see myself wasting stacks of material once my CNC is ready to cut... It's almost as mesmerising as watching a fire!
