General Mach Discussion / This GCODE make my cnc motor loosing steps

« on: September 11, 2015, 01:28:07 PM »

Hello, I just broke my tool because of a thing I can't understand, the following code make the tool go up very fast (faster than configured in mach3 ? possible) and the motor lose some steps, which is... NOT GOOD !
This is the gcode:

Code: [Select]

G01 X21.3632 Y-0.3265
X21.3582 Y-0.3354 F500.
G02 X21.259 Y-0.48 I-0.8717 J0.4914
X20.9725 Y-0.8026 I-3.6232 J2.9299
X20.8609 Y-0.899 I-1.5468 J1.6772
G03 X20.771 Y-1.026 I0.1912 J-0.2308 F87.743
X20.7588 Y-1.0646 Z-2.5627 I0.3858 J-0.1424 F500.
X20.7506 Y-1.1042 Z-2.1189 I0.3979 J-0.1038
X20.7462 Y-1.1444 Z-1.6751 I0.4062 J-0.0642
X20.7458 Y-1.1849 Z0.1 I0.4106 J-0.024
G01 Z2.5
X38.7506 Y-0.8455
Z5.

I think it happens before the "G01 Z2.5" but not very sure.
Then my first question is, is a program able to make the motor go faster than configured ? (I tried to reduce the motor speed very much and it is slower but too slow for other operations.
Then my second question, when I move using the keyboard is it the fastest speed as configured "motor tuning" ?

Thanks in advance for your help.

General Mach Discussion / Can mach3 correct Z height along X and Y moves ?

Hello, I would like to know if it is possible to say mach3 for exemple to add 0.01X to Z and 0.005Y, to correct a inclined plane.

Thanks

G-Code, CAD, and CAM discussions / 4th axis turns for 359° instead of -1°

« on: March 20, 2014, 04:02:32 AM »

Hello, I am trying to use the 4th axis with solidcam, and in fact in works, but when it does movement outside the material a good thing would be that it wouldn't do a full rotation when it goes (for example) from 355 to 0.
Here is a gcode example:

Code: [Select]

S1000 M03
G00 G54 G90 X21.5875 Y0. A-88.588
G43 H1 Z30.
G01 G94 Z13. F300.
A270. F600.
G00 Z35.
X19.5875 A-88.588
Z33.284

Thanks in advance !
