New build with recycled parts on a ridiculous budget 120cm*60cm work area

I guess what I'm asking is can I get away with buying the Ethernet version of 7i76 on it's own?

Yes as I said just the 7i76e.

When I press - on the manual move buttons for the Z axis should it move up or down? I'm guessing down at the moment mine moves up lol.

What do you mean by this it depends if you press on up or down keys

Also on the Z axis it should show -ve when going down. But in the the homing routine you can make it go either way it depends where the switch is ie you can change the travel to seek the switch out.

You are wasting your time playing without the homing switches on. As I said baby steps

-ve right I have it +ve at moment, and I have the router on the X axis going left -ve, right +ve and the Y axis -ve away from the front and +ve towards the front where I load.

As long as the M3's come today they're on ;) the wiring is already in place and connected to the BOB and spade terminal the other ends.
Stuck at home for an hour so can't play waiting for the guy to come see why my boiler stopped working it's going to be the thermocouple it always is. The house I live in was built in the 1920's and it's bloody freezing without heating lol.

The other error I kept getting was joint following error which I traced to the PC isn't fast enough really played with different latencies and ferror settings to no avail but I do know this PC is utter crap so will swap a different one in.

If you are standing at the machine with X going from left to right (- to +) then Y should be set with - at the front and increasing as it goes away. Convention says that X=0, Y=0 is the LH corner nearest you, although that's not essential. However, the relationship between X and Y is very important because your machine needs to be set up the same way as your CAM software. Z usually is zero at the top of travel and - at the bottom (so Z machine coordinates are always negative, except at the very top of travel).

If you are using F360, look at the little RGB axes that come up on the drawing screen, and imagine those transplanted on to your machine bed. Orientation of X, Y, and Z absolutely must match.

[Clive S]

I agree with Neale but I have to admit my X and Y 0 are at the top left of my router looking from the end so that the gantry is furthest away from me, this is so I can use the bed as a dumping ground when not in use.

[Neale]

In fact, on my machine, home and zero positions are bottom right-hand corner. Historical accident - I set up the machine with X along long axis, Y on gantry, intending to stand at the side for loading/operating. In practice, I stand at the end but haven't got round to resetting everything. I just have to remember when I set up a new piece of work. However, the really important point is relationship between axes. For example, it doesn't matter if you choose to home at max travel or min - just a simple setup matter. Just get those XY directions right!

Replaced the linuxcnc machine with a core i7 (Think I need to restrict the cores for max performance) and now I can run the machine fast enough to firing a stall protect consistently which I guess is my upper speed limit. Somewhere around 4m/min with the 1400mm ballscrew which is a little faster than I thought it would do this is no load any faster it makes a funny sound and stall protect I think this is screw whip but hey just guessing.

At moment I have it running 2.7 used stepncof to set the A step and dir pins to Y and we have as much control as I had on 2.8 lol, same errors firing up but had enough went through 4 pc's before finally giving up and using my fusion 360 CAM machine set up as a dual boot.

Have the switches on need to configure them as I was checking the switches I managed to pull the wire out the X dir socket on the BOB just enough to not work but not enough to actually be visible spent 2 hours tracing and fixing that this time I put crimped them with ferrule ends they're going no where.

Worst part about the cheap BOB's is the sockets are just crap you can work with them but I'd rather pay a few quid more for some decent connectors.

Mate wants a catweazle sign to name his pond so mocked him a quick on up last night.



Was discussing dust shoes last night and my mate suggested I buy a brush head cut the centre bristles out and drill 2 holes in it and add some magnets.

Found the idea interesting and also very simple so going to see what brush heads I can get today.
