Zoli, I just ran your code through my machine and it cuts a good bore without the stepping in your picture.

I captured a handful of parameters that I use for you to compare...not that I feel this is the problem. They are just for reference since we both use Leadshine drivers.

--- Quote from: old Zozo on May 07, 2017, 11:34:15 AM ---I tested again. Nothing changed. What I tried to change:

-time duration (Dir/Puls)
-interpolation period
-acceleration

I see in the display,
when the tool finished the spiral movement, Y axis steps minus 0.2 mm.
-but why?
This is the 0.2 mm stairs.

Could somebody runs my gcodes? Not machining, only in controller.

When gcodes run out, you need to see last coordinates.
Correct coordinates are : X-29.5 Y13

My controller has false values, X-29.5 and Y11.8 !

Thanks, Zoli

(attached file: D10pocket.txt
Zmin= -10 mm
Zmax=5 mm
Pocket diameter= 10mm
Pocket centre= X-31.5 Y13)

Probably you are using the backlashing function on setting of parameters

Great suggestion Antonio. Interesting to hear Zoli's response.

Here are my parameters....my computer hiccuped earlier and posted before I could finish typing.

Parameter # = Value
5 = 5.000
33 = 950
34 = 1000
35 = 1000
36 = 5000
39 = PULES/DEGREES
390-392 = HIGH
416 = 100
418-420 = LOW
45-47 = 300
100-108 = 3000
263-265 = 300
99 = 1300

old Zozo:
Rob, thanks again for your help.

Antonio, that is good idea, but I have no backlash so its value is 0.

Rob, I compared parameters now.

Different:

yours my

33 = 950 50 mm/min
34 = 1000 125.984 value depends on pitch of spindle and microstep
35 = 1000 125.984
36 = 5000 262.467

390-392 = HIGH LOW
416 = 100 5000 I tried 100 too, but no better

45-47 = 300 100
100-108 = 3000 1200
263-265 = 300 100
99 = 1300 100

I can not see capital differences, so I am loser yet. :(

PPRINT:
Zoli, there are no losers in this hobbie. It's all just challenges to sharpen our skills.

I have 25mm pitch ballscrews on x&y axis and 5mm on z.

Because of that high pitch I have my micro steps set really high. I'll have to validate tonight when I get home.
