Tangential knife lifts

Сообщение jamesd256 »

Hello

So far I have had good success with the software, but I have one problem.

I need gcode with few arcs, because arduino / RAMPS doesn't handle arcs well. This I can do by setting the arc angle to a very high value.

I would like to have lifts between moves for the tangential knife, but so far can only make it lift every time via the parameters.

I would like to have it lift only when the angle is greater than a certain value, so that it does not lift between segments of a circle.

I am willing to make changes to the code if it's not supported. Any suggestions?

Thanks for the great software.

It looks clear that it's not supported from the code, but also clear it's easy to implement:

In gcodetools-dev.py [4625]:

Код: Выделить всё

		if tool['lift knife at corner']!=0. :
					g = "G00 Z%f  (Lift up)\n"%(depth+tool['lift knife at corner']) + "G00 "+ g + "G01 Z%f %s (Penetrate back)\n"%(depth,penetration_feed)
				else : 	
It seems like this is the place to check the angle before doing the lift. The angle is checked before against TURN_KNIFE_ANGLE_TOLERANCE on line 4621
