uhhhh.. its called a spot gun. it has a motor that generates a vacuum that creates a very high velocity microstream.. so high that if your fingers cross the stream it injects the water under your skin creating instant "blisters".. you were warned...

it depends what you cutting with, usually i use a tapered ballend and there is not need to clean up with more than a soft paint brush, but with pyramid (3 flute) or profile tools you can get compaction in narrow spaces and this si very much dependant on feed/spindle speed, too slow it compacts, too fast it melts back to the surface, in either case you need a reverse vacuum watergun to clean it up.. dangerous when you have parts with fine detail..

Hi Chris

I like the idea of having A & B axes.

But I worry about the layout of the electronics. I had a very compact box like that once. It was fine until it stopped. Then I found out just how hard it was to work on it! Verged on the impossible. OK, it WAS impossible.

My current electronics system is very much '2D' in layout. You can get at everything from above. Debugging is easy. Since my system has just had a total rebuild, that was a bit essential. Yes, total: replaced the USB SS with an ESS, added two MB-20 BoBs, replaced the old (dying) servo drivers with Gecko 320Xs, replaced the (spectacularly) dying SCR-based KBMG spindle drive with a MOSFET unit (much quieter motor but the RFI was incredible), and added some custom interface cards and opto isolators for the encoders and the eStop system. Getting a CRO in there was so easy from above.

Cheers
Roger


Hi Roger, yes, been thinking about a rebuild of the controller,
I actually have a old server that is in a MASSIVE case.. and its current board is more than ample to run Mach3,

and if i dump its raid array and dvd rom bays, the driver boards etc would easily fit..

but..

that is  a project for another day.....

Hey Tweakie, long time no see.. thanks dude. Yeah the X is still way off, if you watch the last cut from A0 you can see the "offcut" wax has thicker areas in X.. TBH havent dailed in X and Y yet, but 5th is quite forgiving Wink

Setup all the homing and G54 offsets at last

Thanks I got help.  Issue resolved

Hey All,

Need some help from the code junkies please.. I have an existing macro that does my homing and a tool pro be for me.  it runs like so:

Z, Y, X then Probe.  https://www.youtube.com/watch?v=gQVm4YjLM3E


I have since upgrade to a 5th axis, and I need to home A and B as well..

BUT

B = no issue as it cannot crash anything//

A = Issues..

then script will need to run as follows now:

action sequence:

1. Home Z: then Move Z to a safe distance. (say 10mm down from home switch)

2. Home X: then Move it to Fixture 1(g54) X0  (XYZ share one input signal, I have to move off the switch for next axis homing run)

3. Home Z: then move it to Fixture 1(g54) Y0  (XYZ share one input signal, I have to move off the switch for next axis homing run)

4: Home B:

5: Home A: then move A to -A45

6: Probe Tool: (note Z MUST stay at same height until its directly over tool probe before going Down Z.

7: Return to the safe Z (10mm below Z probe) over X0andY0


So! Most of the code already exists, and the tool probe position is programmed via my interface so all I need added are the A and B bits..

Any help appreciated folks!

(here is the current standing of my build, jsut about ready to start making noise!! https://www.youtube.com/watch?v=gQVm4YjLM3E)

and attached is the current Macro. (adding it as file because code is being converted into smiley characters by forum)

ok so i progressed..

the machine is pretty much modelled so i can detect crashes and I have written a few paths to play around..
