From a couple of days with PokeysCNC and MAch3. So my new machine almost finished/ project 2 from signature/, work piling up and still could not make a proper cut.
Where i am:
-Mechanically there should not be a problem as all servo motors use keyway to the pulleys, nothing seems loose and all axis show nice repetition.
-Basically the Samsung servos are autotuned using the Samsung software. My first servo machine, so that's all i know :-)
-Next following the manual Pokeys57CNC is connected with MAch3
-In Mach 3 all is set up to 10000mm/min max and 1500mm/s acceleration, though all works ok twice faster /3000/
-jogging around all works fine.
-simple toolpaths like profiling square and circle or pocketing work fine.
-all reinstalled from fresh and again and again, then even the bloody screen was programmed again from fresh.
-plugin, firmware and software are latest, mach3 licensed, test toolpath generated in Aspire and seems ok, i tested some old toolpaths that i know they work ok in my small machine
So what's the problem then:
Basically during program if first profile or pocket is ok, then i have a drill toolpath it does all holes like -2mm deep.
So i tested it with 4 squares: all is perfect, first square 1mm deep, second 2, 3 and 4mm.
Start drilling though or change from one type of toolpath and looses ~2mm.
And the thing is that it does not lose anything as if at end of program command manually to 0, it goes exactly to 0
Same with V carving. see at the right side of video how it messed things. Basically it started right and then where the corners should be cut it cuts 2mm above where cut should be.
On the video see how it must cut holes from 1mm, 2, 3 to 4 and again to 1mm deep. It misses the first
Thats how it should be:
test3.txt
this one is the only one that does it ok:
test2.txt
These are the first tests, 100x100 square, circle and then drill. The square was ok, the circle ok and just at the end of the circle profile it lifts up instead of closing the circle same depth. Then the final drill holes of course not deep enough.
test.txt
What do you make of all this?Last edited by Boyan Silyavski; 05-05-2016 at 02:14 PM.
