Brains Development / How to bring Slave ax to move slowly than Master ax

« on: June 12, 2009, 06:07:45 PM »

Hello folk!
Friends in the "General discussion" advise me to ask here!
Problem is next - The Master axis (X) longer than Slave axis (A).

Along the full length of master axis, the torch must be over trough suction gas.
Of course at the begin of distance the torch will over front edge of trough suction gas (see the picture), at the end of Master ax torch will over rear edge of trough suction gas.
From here, for to locate torch always over trough suction gas, Slave ax must be slowly than Master ax. If switch on A ax as Slave, the A ax move so fast as master ax. The quantity pulses per unit  don't affect. Slave ax use pulse/unit as Muster ax.

jimpinder - think that it able to solve use the Brain.
If anybody know how to bring to move Slave ax synchronous but slowly, please help.
TIA Inna.

General Mach Discussion / Slave ax less Master ax. Help to move it correctly

« on: June 10, 2009, 03:21:05 AM »

Hello friends. Sorry if this question was solved. I cant to find the answer.

I make the plasma router. I have A-ax for move trough suction gas.
The A-ax shorter than the master ax. I tried to cheat - indicated that the A-ax allegedly took place as long as the Master ax, but if turn on axis as a slave, that moving exactly as the Master.

If disable slave and insert formula (for ex. A=X*0.9) (in G-code I don't use A-ax) When I move X-ax  -   A-ax don't move.

Please help! How I can adjust Mach when I moving X axis - the A-axis moving too, but slightly slower?

General Mach Discussion / Friends! Advise good CAM for Mach3 plasma

Hello friends!
Advise please CAM for Mach3 plasma, that can good read DXF files and make good G-code with interpolation!

Thanks Inna.

Feature Requests / Self behavior of G-code

« on: November 16, 2008, 03:38:22 PM »

I offer to Mach designers, in the future, insert to the Mach possibility of self redefinition and adding self G-codes. As it possible with M-codes.
 
For example  some postprocessors makes G28, G29 etc. I'd like to have tools on VB or other, for write self behavior of this codes.

I think, with that Mach will adapted to many postprocessors.

Thanks. Inna.

General Mach Discussion / how to create own treatment for mach unknown code f.ex. G27, G25?

« on: November 09, 2008, 03:51:01 PM »

Hi guys!
I have, (for plasmacut) for generating G-code some program "Techtran"! This program can make G-code for many NC, but not for Mach!
For example:
G25 - turn off torch
G27 - examination THC and turn on the torch.
For Mach3 its Unknown G-codes.

I know how to modify treatment of M3 or M5. But I dont know how to create own treatment of G-code and the more so to create treatment of new G-code.
Explain please if anybody know!
Thanks!

General Mach Discussion / Quastion about 2 motors on one ax and correcting by encoders

« on: November 06, 2008, 05:04:25 AM »

Hello everybody!
Please help to new user. I was searched an analogical theme, but did not find it. Give me please link, if this theme understood already.

Problem: I have tow motors on one ax. I try to use X ax stepper motor as master and A ax stepper as slave for synchronous mowing. Both motors have encoders(but not connected yet).
I was turn on A as slave, turn on "Formulas", where f(a)=X or f(a)=x*(-1) and in the "General config"->"Home slave with master axis". And nothing changed - A ax don't move, when I press arrow keys, or MDI.
Both axis move just when I press "GOTO Z".
Who know what I do wrong - please help.

And one more. Does anybody know how to turn on motor correction by encoder. I was connected encoders and in the settings screen I see that its work, but it have no affect to motors. Explain please, how it must to work.

Thanks. Inna.
