Autoleveling

[kuba120]

Používám na ovládaní CNC Armote chtěl bych frézovat DPS je nějaká možnost autolevelingu.

[Dawe]

Jasne.

Pomuze napr. utilita Autoleveller ktera funguje jako postprocessor, kterym zpracujes uz vyexportovany etch file s gravirovanim (vygenerovany napr. z Eaglu).
Link zde.
Ta utiita udela dve veci -
1) prida na zacatek proceduru mapovani vysky Z. Tim se vytvori (po castech linearni) mapa offsetu povrchu v ose Z.
2) zmeni vsechny Z souradnice v G-kodu z konstant na vypoctitavane korigovane hodnoty na zaklade zjisteneho offsetu z mapovani.
Nastavit si muzes hustotu rastru ukterym tu vysku Z chces namapovat a par dalsich parametru. Sonda staci primitivni v podobe dvou krokodylku. Jeden cvaknes pro mapovani na nastroj, druhy na povrch PCB. Nechas otukat, sundas to a dal se graviruje s korekci Z. Trva to par desitek sekund.

Exitujou i jine metody, ale tahle je fakt snadna a univerzalni.

edit:
Utilila umi taky vykreslit jiz zmapovany povrch ve 3D ve zvetsenem meritku osy Z, takvova vizualizace... ale v souvislosti s gravirovanim PCB spis jen pro zajimavost.

no jo ale jakou sondu použit pro Armote a ten program podporuje Mach3, LinuxCNC tak nevím ale vypadá to super to bych přesně potřeboval

[robokop]

Gravosaci maji svoji sondu
Nevim ale jak je to s tim skenovanim povrchu

[zverodoktor]

Ahoj,
funguje ten autolelveler na akékoľvek súbory, alebo iba na G-code na PLSP s Eagle?
Vcelku by sa mi niekedy hodilo napríklad pri gravírovaní do dreva korigovať nerovinnosť.

Nebudu predstirat ze znam Armote. Neznam.
Ale myslim ze Autoleveller s nastavenim G-code outputu pro Mach3 (je to v podstate volba postprocessoru) to generuje celkem standartni G kod. Myslim ze to pujde spustit s minimalni upravou na vetsine systemu, kde je funkcni nejaka sonda. Ale nejsem zadny G kod odbornik.

Dam sem dva useky vygenerovaneho kodu (jedno moje PCB) abyste to sami posoudili.
pozn.: a predtim jsem se prepsal. Interpolace zmapovaneho povrchu je bilinearni nikoliv po castech linearni.

Jinak jako vstup to basti asi jakykoliv smysluplny G-kod. Zkousel jsem export PCB z Eagle (PCB-gcode ULP) , export dwg ze Solidworksu, export PCB G code z Altium a dalsi).

Jestle jsem take pouzival utilitu G-code Ripper. Ta mela taky podobnou funkci autolevelleru. Ta byla vhodna spise pro vetsi zakriveni, jako gravirovani na povrch koule apod. Ale nic nebranilo ji pouzit i na PCB. Zkuste pohledat.
