Great stuff Rick, now lets see some swarf/sawdust. G.

LOL the bed will be cast next week and then there is the Y to mount and that will be after the Z backplate arrives.. So its all in flux, Im waiting for the Drag chain, grommets, inline plugs, and the proximity sensors to arrive, then i can chase all the wiring through the frame and through the drag chain (damn that stuff is expensive) there is a bit of welding under the frame to be completed for the shelves for the vacuum pumps, and the dust sucker, the coolant reservour, compressor,VFD, and plasma . But im going as quick as i can cos i want it going..

Sorry Rick, I thought you were a bit further down the line than that. I had not realized you still had so much to do, but at the speed your'e going at it won't be long now. G.

Well there is a lesson learned!!.

Today I fitted the drag chain, and spent two hours drilling, and routing the cables through the frame back to the control box, Oh how neat it was, i fitted three bright new NPN-NO-6-36v proximity sensors to the X- Axis....LOL oh what fun that was.

Evertime i powered up the driver a sensor triggered, I didnt know what was going on.

I had used some 5 core cable for the steppers leaving 1 spare wire in each cable for the sensor, I had already run some wire up to the gantry for the sensor supply..

So now that i know i will have to use Screened cables on the machine so i dont get all these stray signals.
Can anyone suggest a four core screened cable that wont rip my arm off please, as i will wire the whole machine with what ever i get.

The drivers are 2MA860H Peak 7.2A AC50V-80V DC36V-110V running at 72VAC driving 4NM NEMA 24 Motors

Here you go. CY Cable 4 Core

Don't run power cables along side signal cables.! Even shielded cables else your asking for trouble.

Cheers Jazz.. So how do you get power cables up onto the gantry?

Dean,
Is that 4 core 4 numbered cores plus earth or 3cores and earth ?

4core = 3 numbered + Earth Need eyes like super man thou to see numbers not very good in that regards but it's cheap enough and Ok quality.

Carefully. . .Lol . . . They will be ok in same Cable chain if not too tight Just don't fasten them together with cable ties/tape or owt daft like that.!!

Just a daft thought, but if interference is a problem here would putting a divider in place made of copper tape help isolate the data/power?
