CHook - drawing to g-code

[wire123]

pt1[X] = 2.5000 pt1[Y] = 5.1260

pt2[X] = 2.4380 pt2[Y] = 5.2500

pt3[X] = 1.2500 pt3[Y] = 5.2500

pt4[X] = 0.0620 pt4[Y] = 5.2500

pt5[X] = 0.0000 pt5[Y] = 5.1260

pt1 to 2 and pt4 to 5 are 0.062radius 90deg arcs (0to90 and 90to180 respec.).

Pt2 to 3 and pt3 to 4 are equal length lines.

I can draw the above 4 entities.

I have managed to draw the above chain using only one CHAIN(chnAll) and one CHAIN_ENT (lastCe).

 

LastCe = NULL;

err = add_curve_to_chain(&entRtOCR, 0, TRUE, TEMP2_BIT, chnAll, &lastCe);

draw_chain_direction ( chnAll );

lastCe = last_chain_curve(chnAll);

err = add_curve_to_chain(&entRtLine, 0, TRUE, TEMP2_BIT, chnAll, &lastCe);

lastCe = last_chain_curve(chnAll);

err = add_curve_to_chain(&entLftLine, 0, TRUE, TEMP2_BIT, chnAll, &lastCe);

lastCe = last_chain_curve(chnAll);

err = add_curve_to_chain(&entLftOCR, 0, TRUE, TEMP2_BIT, chnAll, &lastCe);

draw_chain_direction ( chnAll );

draw_chain( chnAll, 11); //12=red, 11=lt blue, 10=green

draw_chain_sel( chnAll); //not exactly sure what this is doing

 

A call to chain_manager() sets succf to TRUE.

 

Does every entity in a complete chain need a CHAIN_ENT?

 

What I want to do is have the chook finish up and create g-code.

I’m not entirely sure what calls and the order using operation_manager(), tool_manager(), chain_manager() & nci_manager() I need to achieve that end.

Any suggestions would be welcome. I’ve read the C-Hooks FTP download which I used to accomplish the above.
