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

[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.

I've got it to run the splash screen ;)

Running 2.7 at moment with now working home switches, am going to upgrade to 2.8 but this was a fresh install so thought I might as well have a go.

I wasn't touching off each axis I assumed it was only for the Z causing most my errors.

My dimensions are wrong and not sure why will have to investigate tomorrow but when I move 1.2m I'm only really moving ~85cm so need to do some head scratching.

My microsteps are set to 8 and the ballscrew pitches are correct, it's set to 1:1

I also have the emergency stop button but unsure how to wire it up no instructions of course with the super cheap chinese stop button but I never expected anything more lol.

I did have it running a couple of weeks ago with Mach 3 but as soon as my mate went Oz I deleted the dodgy pirate and installed linuxcnc he's back in a week so glad I've got it working before he got back lol, he's a Windowsphile.

Bought a dust shoe
http://www.ebay.co.uk/itm/80mm-White...72.m2749.l2649

Think it's the same as you linked to just different colour, but UK ship although slightly more expensive.

I'm going to use a vacuum cleaner to suck on a cyclone wondering if I can use 100mm fittings on the cyclone to run a 100mm hose to the dust shoe or should I make an adapter so I can run a smaller hose to it.

Hmmm decisions.

You did realise you can buy those dust shoes with different hose sizes
