Hey Les, just wondering of you have a easy way (other than manually moving) to place start points on the opposite side of the contour?
Any thoughts how to do this optimization automatically?
As you can see in the screenshot, sheetcam is placing the start points on the leading side of the contour in the direction of rapids. The problem here is sometimes the cutout twists sideways and does not fall all the way out and the machine rapids into the piece that is sticking up and crashes. If the start point was on the opposite side of the contour, as how i placed the first few, this would not happen and i would not have to use a negative overcut to tab them and then not waste hours poking out all those dang little squares.

Re: Start point placement
There isn't anything like that in the current SheetCam. I lik ethe idea but it's likely to be tricky to implement. If you move the start point it may change the optimum cut order. This in turn could mean you now need to move the start point again to allow for the new cut order. It could easily end up going around in circles trying to find a solution. There are ways around problems like this but it's something that needs to be approached with care.

Re: Start point placement
I think it would be an amazing addition to sheetcam. After I spent the time to manually place all those points this morning, all 6 sheets cut perfectly without a single crash and every little square fell out when we picked the sheet up.
Could you perhaps limit the number of times the cutpath is evaluated after a single user action? I see what you mean it could potentially form a perpetual loop of optimizing the paths, but just limit it to 5, 10, etc. optimization attempts until the user changes another parameter?

Re: Start point placement
Isn't it possible to increase the safe height in your case? Or is it at maximum already?

Re: Start point placement
Unfortunately that will not solve the problem. This is a production laser machine, the movements are optimized for speed of processing. The head retracts as the XY rapids instead of the head retracting then the XY moves. It is dangerous and much more prone to crashing, but significantly reduces processing time with a lot of pierces.Isn't it possible to increase the safe height in your case?
