I'll post my settings- I'm sure I could increase the step over some- but the Machining time calc in vectic showed 30 minutes originally with a scale factor of 2. In actual time, the scale factor should have been 6 to calculate accurately for 1:30min. If anyone has any parting advice on speeding up this time, I'm all ears. Thanks again all!
I'll try to suggest some since I am going through a few myself. First, I assume your 1:30 is hour not minutes. On my machine and calc within vcarve, my cut time is usually always half of what vcarve calculates. So I am not sure about your machine and setup. You also didn't say (or maybe I missed it) which tool you are using for the rough and the finish. My first suggestion would be to use a larger tool for the rough. If you are using a 1/8", try it with a 1/4" end mill. Same with the finish. Although a 1/16" ball nose does a better and more finished surface, perhaps the 1/8" ball nose would NOT be so bad if it cuts the finish time in half or more. Those are my only simple suggestions. I am sure others will give more higher level tips... good luck!
Also, I don't consider a 1 hour or more finish time so bad. Since the tool cut is so small, I don't need to stand hovering and cleaning up debris as much on a 1/4" EM cut. I don't have a spindle shoe because I am adamant to watch what my job is doing. I live out in the country and unfortunately I get power surges/purges occasionally which my Chinese machine doesn't like and because it is touchy on the frequencies, it could throw off my settings. I have several ground running outside to the ground, so I can't think of anything else to help it. I also have a heavy duty UPS with built in power p/surge protection although it doesn't seem to help. It is usually when a storm is passing through. I try to make a habit to pause and shutdown until it passes. I tell the power company folks and I get the deer in the headlight reply... sorry to ramble..
