So according to your calculations of never exceeding 12 ipm set at Still twice as fast. This theory remains the case whatever your max ipm is set at. But as I have stated in many other posts of the same discussion. So, set the same feed rate for the roughing and detail passes and time the roughing pass and detail pass I bet the roughing pass takes a lot less time.īut a 90 deg corner in the Z movement. So setting your feedrate to ipm makes no real difference, during the 3D detail pass your spindle will never be moving at ipm. The second limiter is due to the time it takes for Z axis to reach the next height. That is not the acceleration limiter I am talking about here. The first is the acceleration control necessary for the spindle to turn, the closer the turn is to 90 deg the more the spindle needs to slow. But even if you are doing a raster pattern where X or Y is not changing except at edges, the Z axis is in near constant motion. If you are doing a spiral or offset pattern, then the spindle direction is constantly changing which can also lower feedrates. Why do 90 deg corners make any difference? You may be talking about cornering algorithms that will slow the machine to allow it to turn without exceeding max accelerations a very tricky problem. The Z always moves in conjunction with the X and Y.
I have yet to do a 3D module that has 90deg corners. If you match 125 amp wire size requirements plunge rate your z will also move that fast. A smaller step over at ipm very little if any sanding. And nobody will pay the price that you would want for all the time spent. But if you turn them into g-code using aspire you will also have to sand it down after carving which is a lot of work.

There no good for 2D laser engraving, but work very good for 3D laser engraving, or cutting a spindle relief with an image to gcode program like our PicEngrave Pro 5. Those Gray Scale images good for Laser Engraving to flat surface.
Go into Google images and search for 3d grayscale images.
