Ar last!!! Started my Gantry 3-Axis CNC Build

[lucan07]

Had a look for my bearings documentation but could not find picture but did find this one online from same supplier same as picture which was on leaflet which got recycled except for being open bearing for supported rail. As it goes the fact that they all used to be sealed helps me, I have removed nipples on Z axis can always pop one in annualy to grease them again, but they got in the way a little as I hadn't allowed for them.

😁 nice one Mike, always good seeing the first chips (or dust in your case!!!) from a machine...looking forward to seeing more. You do know that you'll be constantly doing more bits to it don't you? I've just made an ali corner finder to go with my touch plates, next is dust shoe mk2 then a better mist/fog nozzle system, then web cam in dust shoe....it goes on 😁

Poser.!!. . .

Well done Mikey know it's been long slog but you done it correctly and you'll soon start reaping the bennifits. (go easy on DOC else you'll be replacing beds every other week.!)

Regards the false E-stop have you Earthed the Machine Frame.?

Hi Jazz

Yes it has been a long slog as you and I well remember! Thanks for the tip on earthing the machine. Should I earth it to the star earth I have in the control box (all shielded cables from machine to control box star earthed) or run it back to the mains earth?

Regards
Mike

Yes to the Star point.

Thanks Neil. Ideally I would like to get the proximity homing switches working so that I can get tool changes consistent and touch plates. These items improve productivity.

That's the best thing I've done on my machine, makes life so much easier and jobs quicker! What BOB/controller you using?

I am using the Zapp BoB ZP5A-INT and the NPN proximity switches as suggested by Jazz some time ago. I posted this a couple of months ago, but could'nt get it working. I have a separate 24v PS for the relay safety system which I also wanted to use to power the prox switches. But if you or Jazz can give me some inspired thoughts I would be grateful

Thanks Jazz I'll try that first before getting the EMI filter

Hi Jazz, manage to get rid of the noise by doing everything you said and using an IEC EMI filter socket for the mains input to the control box, as well as using a ferrite coil around the RS423 Modbus serial connection between the Mach3 PC and the VFD. Now it runs reliably. Got all the bits for my dust filter and about to cut the dust shoe from 10mm perspex. Will post the design and pics soon.

Cheers.
Mike
