G-Code, CAD, and CAM discussions / Re: Variable filenames in M98 subroutine call?

« on: February 23, 2012, 11:16:43 AM »

Are you trying to call SUB form within the program OR OUTSIDE subs.

Inside subs
#10=10
 M98 P#10 L1

o10
code
code
#10=[#10+5]
M99


Outside subs I have never tried to use a #var and am NOT SURE whether  it would work but I will give it a try. The problem IS the outside call par tis NOT a normal Gcode function.

Can you post an example program?

ONE thing to rememeber you must reference the part back to the machine exactly like you did the first time.

At each section of Gcode place the o word holder

o001

code
code

o002

From inside a CB macro,  code" M98 P002"  ,and it will take you to the o002 position. Press run or code the dooembutton() and off you go.

General Mach Discussion / Re: spindle speed tied to feedrate speed, is it possible ?

Please let us know how it works out others might could use the function.

General Mach Discussion / Re: spindle speed tied to feedrate speed, is it possible ?

Easy enough to do , Buld a Brain that monitors the Feerate then divide that by the starting value.

100 Ipm  Starting value feedrate
3000 RPM starting value Spindle speed

Actually feedrate 90

90/100 = .9

THen multiply the SSO by the same multiplier.

3000 rpm X.9 = 2700 rpm

This will tie you togther as a percent of change. When the feedrate changes the spindle speed will change the SAME percent of change UP or Down.

I used to have somthing similar that tied the Spindle Speed to the feedrate. IF the spindle BOGGED a bit mach would SLOW the feerate and allow it to catch back up. SOrt of a SPEED control to help keep from overloading the little steppers and loosing steps.

Just a thought(;-) TP

General Mach Discussion / Re: Plasma - Handling misaligned materials - G68 does not work

EFE you won't have to modify teh POST just use the one for THC300.

Let me know IF you need more help with it.

General Mach Discussion / Re: Plasma - Handling misaligned materials - G68 does not work

HIYA EFE, As you have found out MACH3 will NOT allow you to run the G28.1 while in a G68 rotated position. This is a MACH3 problem that really puts a kink in using the G68 for most plasma work. AND in this case the G68 is needed more here than in most other uses of MACH3.

THere IS a workaround.  Instead of using the G28.1 Zxx  (refhome Z ) You have to set your plasma up to USE the G31 function to find the TOM(top of Material) it ALSO has problems BUT will make the G68 useable for plasma cutting.

SO what you need to do is setup your floating head contact to be a probe instead of a home switch. Then use a different POST that calls the G31 instead of the G28.1. In  Sheetcam you would use the THC300 post instead of the MP1000 post.

Hopefully some day Mach3 will allow it to be done using the proper G28.1 call.

Hope that helps, (;-) TP

It is going to depend on IF the problem lies in the table top or the slide mechanisms. IF it is in the slides then you will solve nothing cutting the table you will still have problems. Also what  type mill are we talking? Bed mill gantry mill knee mill .
