General Mach Discussion / Re: Plasma Z floating head
« on: May 10, 2018, 02:44:05 AM »
i assume that you fire up the torch via M3 command.

so you can modify M3 macro code to do the Floating head procedure.

i am not familar with LUA coding of Mach4, so somebody else must
guide you, if you want to go this road.

General Mach Discussion / Re: Plasma Z floating head
« on: May 10, 2018, 02:32:57 AM »
here something what a simple search in the Forum showed:

You can set it up one of two ways using the G28.1 method OR use the G31 method.

With the G28.1 method you set up your floating head as the Z home and have it  home toward the bed. Then the Cam that you use must generate the following type code.

N0120 G28.1 Z0.50
N0130 G92 Z0.0
N0140 G00 Z0.1370
N0150 G92 Z0.0
N0160 G00 Z0.2000

With the G31 method you setup the floating head as a Probe then you cam must generate code like

N0120 G31 Z -100 F19.685
N0130 G92 Z-0.0800
N0140 G00 X5.5505 Y9.8813
N0150 Z0.0000


Hope that helps, (;-) TP

BTW do you have an Manual of this router ?

a screenshot of the Motor Outputs would be interesting.

ok then back to the originally question.

yes you can use this probe and mach3 wizard to create Point cloud's.

you will Need extra Software, no idea about Vectric Aspire, to create a 3d model of this Point data,
and the create a GCode.

the probe will be connected to a Smoothstepper Input, and this Input has to be configured as probe Input.

619
well. digitizing is a very "hot" Point.

you are talking about "accurate model ".

what do you define with "accurate" ??!

let's say you have a door Panel 200x100 cm, and you what to have a probing every 1mm,
ok that Needs 2000000 Points (in word's two million's).

i hope to give you a idea what accurate means, because every modelling Software is "living"
from data.


3d scanning is your friend, if you what do do this, but this is an other $$ diamention, as we are talking about.

sorry that i have "destroyed" your idea.

Back in the old days before CNC that old Bridgeport had a number of  ratios, you selected the speed closest to what you required and got to work. Are you trying to tell me that all those jobs I did with manual mills and
lathes were compromised because I did not have the exact speed ratio available? Of course not, provided the surface speed is within 20% of the recommended for that material you can always find a feed that worked well.

Craig

Back in the day, the BP only went to 4200rpm max and the brain controlling the handles was very adept at altering rates depending on how the tool sounded and th colour of the chips, BUT it was never running a tiny cutter at 24,000rpm - there is no sound apart from the 'ping' when it snaps ;)  I'm not having a dig or anything, far from it but I would never state that speeds do not matter ;)

sorry guys thats an never ending Basic discusion, and i am realy sorry to say that, what has nothing to do with the Basic thread.

sorry again Thomas.
