G'day Hood

Yeah I just tried 034, and it is all screwed up for me.

Feedrates are oscillating up and down.

Don't know yet if it is just me or a problem with the new driver update.

Reverted to 033 and all is good again.  Or at least like it was before.  

Greg

Oh well hopefully things will be fine in Rev4.

Actually I am very happy with 033.

The long standing rotary axis feedrate bug, that I have been complaining about for over a year, has been 90% fixed.

Happy as pig in mud. 

Greg

Lucky you are not in Scotland at the moment then as the pig would be frozen into the mud and not too happy

Hood

version 034 has corrected the feed issue. Thank you very much.
My motor max velocity is 850.2mm/min (for some reason the 0.2 gets added when i enter 850.
The machine now jogs and accelerates properly at 849.9mm/min.
Close enough for me. Thanks.

glad to hear that, hopefully this kind of thing will not happen with Rev4.

Hello
Excuse me, I have a problem, may be like this (I don`t know).

For example:

Position "0" (to look black labels)

M30
O1234
G1 A5
G1 A0

Is it bug of Mach?

Help me please

Has forgotten to tell - Steps for A-axis 8.8888 (200*16/360)
And not understand:
type G01 A10, but in window: "+10.0126"
G01 A360 - "+360.0036"
G01 A720 - "+720.0072"...Etc.

Pavlll,
I think what you are seeing is because of your steps per degree.
If you move 10 degrees than the number of steps would be rounded to the lower or higher
of the whole step. Thus you get some parts of a degree like .0126 deg in this case, but at certain angles it will be
a displayed even degree in the dro.
"I think " you would need a number divisible by 360 and 10.8 reduction to get rid of that.
AT 10 degrees you have  .0126 degrees = .756 min = 45 seconds which would be about 0.0025" in a foot.
You can ignore it or accept it for what it is.

So it's a resolution thing and good resolution will come from mechanical for a rotary.

I don't have any dro numbers like that for any angle,but , my steps per degree are 750.

Hope this makes sense,
RICH




 

Thank you RICH
I enter 10 (in steps) today... nothing 
Result like yesterday.
