Next will be a trunnion table that could let me machine several sides of the same part in one sitting.
Hoss

What CAM software do you use that can handle a trunnion table?

Hey Tom,
To start I'm just planning to machine several sides of the same part.
That will be easy enough to use Deskcnc to make the individual programs
and then stitch them together and edit the transitions in notepad.
Getting into 3D parts will be the fun part, get to try out some different software
and learn something new.

Initially, it's just a really fancy fixture, eh Hoss?

Yep, the fixture part is the easy bit.
Getting it do do something is the trickier bit.

Hoss,

I am using the 'hoss1024probing.set' and I am having a strange problem with the Z axis.

When I hit the z probe button, it will probe z- and when it touches, it pauses and then jogs a random distance z-.... crashing the poor tool.

If I comment out the following line, it doesn't jog down and crash, but I am guessing it is not really zeroing correctly.

Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun

example:

CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later
PlateThickness = GetUserDRO(1151) 'Z-plate thickness DRO

If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty
DoOEMButton (1010) 'zero the Z axis so the probe move will start from here
Code "G4 P2" ' two second delay
Code "G31 Z-1.0 F5" 'Z goes down a max of 1.0 at 5IPM
While IsMoving() 'wait while it happens
Wend
ZProbePos = GetVar(2002) 'get the axact point the probe was hit
'Code "G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun
While IsMoving ()
Wend
Call SetDro (2, PlateThickness) 'set the Z axis DRO to whatever is set as plate thickness
Code "G4 P0.25" 'Pause for Dro to update.
Code "G0 Z1.0" 'retract Z to 1.0 inch
Code "(Z axis is now zeroed)" 'puts this message in the status bar
Code "F" &CurrentFeed 'Returns to prior feed rate
Else
Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if aplicable
Exit Sub
End If

Thoughts?

Thanks,

Denzil

I ran into that problem if the Tool Offset LED was On, I turned it off and it ran just fine after that.

Strange thing is that mine is off already. The "Tool Offset On/Off" button doesn't toggle it either.

Am I missing something?

[hoss2006]

you have to have tool number 1 or higher to be able to toggle the LED.
If mine was lit it would drive down every time like you said.
With the LED off it worked properly.
Could be a G90/G91 issue, Greolt was working on some new code.
It's metric, you'll have to change the F's to 4 and the Z height to 1.0.
Under General Config I have Mach run G90 among others in the Initialization String at Reset so that problem doesn't affect mine.

Well, it was a G90/G91 problem.
I was in G91 and it was screwing things up. Once I switched to G90, the problems went away.
I then tried the new script that Greolt put together, and now things work in G90 and G91 (basically it switches to G90 before probing)...

Thanks again.

Number of motors on the Hoss monster?

X
Y
Z
Rotary Table?
Trunion Table
Tool Changer?

Seems like 7 to me, are some temporary depending on setup?

Art of CNC advertises 6 for Mach 3, can it do more for non machining motors like tool changers?

Why, do I ask. As I learn more, I settle on how my projects are going to be configured. At the moment I am of the mind to get a Grizzly G0516 Combo Lathe/Mini Mill/Drill add the table from G1006. I will use the G0516 as-is to manually make the mounts for the G1006 table and perhaps the lathe to turn the lead screws. Them move the column from the G0516 to the G1006 table and presto, a 10x22 lathe and a 22x10x12 mini mill for a fair price. Then use the mill to make the parts to cnc the lathe.

After that, and ATC ala the Hoss monster, a rotary table, then a trunion table. With those made I can make my first parts the way I think they should be made.

Of course at any step along the way, I may chicken out and get a pre-made kit. CNC Fusion for the Z. A ZBot ATC. But everything else I'll probably do myself.

I like the G540 packaging and for something the size of the Mini+big table and the 10x22 they should provide plenty of power. So depending on final configuration, the mill would get 1 complete G540 + 2 or more of the 250's. The lathe would get a G540 and I will try to make a turret changer and I want the tail stock on a motor for automated drilling in the lathe.

The most fun is making the machines, the payoff is making the parts.

[hoss2006]

Mach only uses 6 drivers.
I made my motors with removable cables.
The 4th axis driver will be used for the trunnion table.
If I play with adding a rotary to it, I'll take one of the cables from the ATC temporarily.
You're right, making machines is fun.
Hoss

Having taken the time to read through this, I must say I'm entirely impressed with how you've pulled all this off. I could totally see a set of mods like this once I get a mill of my own. Good luck with the 4th and 5th axes, I look forward to it.

I reran my corner and Z probes to make sure I wasn't getting any strange behavior a few others seem to get,
worked just perfect each time.
Greolt edited his original code to address some G90/G91 issues for the Auto Z probe.
I have Mach setup so it runs G90 among others in the Initialization String at startup and reset
so that may be taking care of any potential troubles.
I changed to his new code just to be safe.
Here it is with my changes for Imperial.

Another note, installed the new home switch for the toolrack.
Gotta get more of them.
Hoss

[dwessels]

Hoss,

Here is the 1024 autoprobe screenset that you made with the G90/G91 fixes added. It is added to all of the Z probing (including the corner probing.)

I also added some error checking (if the probe is grounded when starting a probe, it will exit the routine) and fixed some if loops that were broken.

Thanks,

Denzil

How are you guys getting this code to work correctly? When I run it using the number 1 test button which is the one i use all the time it completely skips the x axis check. I looked at the code for the button and it checks to see if the if the OemLed = 0 which in my case if it is = 0 then the led is not lit which it then should continue the routine to check the x axis zero location but as it is written it sees that the OemLed (825) is not lit and then skips over the x axis check. If you look at the y axis routine it correctly checks the OemLed (825) as not being equal (<>) to zero and follows through with the correct function. After changing the x check portion from "= 0" to "<> 0" it works correctly. I made a comment on Hoss's web site forum about this a few days ago.

I just check all four corner buttons and they are all like this. I was just curious how I can't get it to work correctly as written but the code still gets passed around like this. It must be working for everone else since no one else has had a problem with this.

Rick

Edit: OK Sorry I just saw this is fixed in the most recent fix. I loaded an older screen instead of the latest. Good work Denzil!

Hey Hoss,

Just out of curiosity, were you planning on selling plans to the 16 tool changer anytime in the future?

I'm sure there would be many takers (including yours truly)...

Working on it right now. Should be rolling it out next week.
It'll include the original ATC files along with the 16T ATC files and the Auto Tool Probing.

Oh no, dont tell me I bought your dvd a week to early!!!

Nope, the one you ordered is packed full of info that won't be on the new DVD-ROM.
Same thing with the new one, it'll be full of new never released info.
Hoss

[Starleper1]

how many of those dvd's do you actually sell?
