jimpinder,
Thank you very much for your fast answer and explanation.

Now, if I understood, if I travel with G0 on both axis then the 'longer' axes travels on max speed, and the 'shorter' travels on max speed mutilplied by shorter/longer ratio.
So the DRO's showing the actual speed always will show something more than max speed, if i move with G0 on both axes. In my previous version (2.63) the actual speed for G0 moves was always equal max speed, even for both axes travels. But I think that now is better.

Regarding circles there is something strange. If the LookAhead is set to 1 line, then the DRO with actual speed show 1500 (after acceleration period). For LookAhead 2 and more it shows 848. Is it normal ?

Hi,
I've had the same problem while working with versions 2.62, 3.00  and 3.01. After updating to 3.039 the problem with lookahead seems to be cured.
But now I have problem with feed rates :

Hi,
After updating to 3.039 version (the previous was 2.63) and running below program, some feed rates are different then programmed. Before updating was OK.
My max feedrate (G0 moves) is 1800 mm/min. FRO is 100%.

Here is my program:

G17 (XY plane select)
G21 (mm unit)
G40 (Cancel cutter radius compensation)
G49 (Cancel tool lenght offset)
G90 (Absolute distance mode)
G94 (Feed per minute mode)
G0 Z50
G0 X0 Y0
G0 Y50
F200
G0 Z10
G1 Z0
F1500
G2 I50          (max feed 848, sholud be 1500)
G0 Z50
G0 X150 Y100    (max feed 1897, sholud be 1800)
G0 Z10
F200
G1 Z0
F1500
G1 X200 Y0
G1 X100
G1 x150 Y100
G0 Z50
G0 X0 y0        (max feed 2163, should be 1800)
M30

I've tried it on 2 PCs (633MHz and 2.4 GHz), the same behaviour.

General Mach Discussion / Re: Mach3 current command interrupting
« on: April 21, 2008, 12:16:44 PM »
Hi Robin,
Nice to meet you here ! :)

Currently I work with a retrofitted HURCO KMB-1x with Gecko G320 servodrives. My PC is DELL 2.4GHz + RAM 256MB + HD 40GB. I've tested it on old PC 670MHz also, the same result. All unnecessary in WINXP unistalled as advised on Artsof site.

The jogging works fine, single commands via MDI seem to work correctly. But if I load and run a simple program from a file, some of commads are omitted or not finished (for example it makes 30% of circle and jumps to the next command).

The same is in OFFLINE mode !

After ubnormal run the DROs show misplaced coordinates and in toolpath window I can see a modified toolpath.

General Mach Discussion / Mach3 current command interrupting
« on: April 20, 2008, 11:38:36 AM »
Hello,
After starting a Gcode interpreting, the Mach3 accindentally  interrupts current command and starts the next one before finishing the previous.

It happens seldom and on accindental lines of code.

Anybody can help ?

Thanks in advance..
