Could still be the arc move causing the main issue....though you're seeing the result of the bad move at that position that you point out Run the tool safely above the part and single block it thru that section to find the exact position in the code

I believe the problem lies more in the control...the machines controls arc tolerance is set too tight and can't handle the end points being off my a .0001" As it happens and is not related arc size, as it happens on larger arcs, that kind of negates the arc setting in Mastercam

I had it happen 2 times, verify and Vericut looked great. Vericut sent a person out to video tape the control, after that they had a major software update. The problem was the min arc setting in Mastercam, the control was not capable of reading the code properly.

Since you got a laptop with 64 Gb of RAM, Windows by default will designate 64 Gb of your Harddrive for the Page File (virtual memory). Since you have a 2 Terabyte SSD, this is probably just fine, since you have so much storage space. If you only had a 256 Gb drive, I would recommend reducing the Page File manually, and setting it to 32 Gb or less. With 64 Gb on tap, Mastercam should really not need to swap address space very often, and if it does, the fact you are running an SSD will make the I/O processing very quickly.

Money very well spent, that will pay immediate dividends in terms of fast calculations. You mentioned "solely for CAD" in one of your posts. If you are driving Mastercam, make sure you edit the Configuration File. Under the 'Toolpaths' page, make sure you change 'ram utilization' to 90%. I like to leave at least 8 Gb for Windows to run, but if you aren't running anything besides Mastercam, then I'd bump it to 94%.

Thanks Doug, that is our initial thought. You and the rest of the ones that have responded are very helpful here. When any of you respond to a post I make sure I read it hoping to tap off as much of your guys knowledge as possible. Thanks again everyone and enjoy your weekend fellas.

I've used the dynamite button a few times. It's nice when training people to use the software. After they're done with the part I went through them with, I blow it up, tell them to do it again and walk out the door for a 1/2 hour. When I come back in they start writing better notes.

We have an Okuma LT3000ex. Twin turret/twin spindle. 3" through bore. We have an ABB robot feeding it. It runs on average 65% of the time 24/7. Absolutely awesome thermal comp. We can run for 24 hrs unattended and hold +/-.0005 bores without issue. The only issue we have had so far is we had a part that made 7-10" long tight spiral chips jam up the lower turret cover. I took them apart and pounded them back to working condition but they still leak a little so we ordered a new set ($7000). Other than that the machine has been awesome. Below is an in-cycle summary from our data collection software from 4/1 to today.

Okay I see now, if there is free one available, that should also be fine, no need to migrate this file. Thanks for the info, didn't now that.

Years ago I took a Solidworks class at a local community college We sat 3 computers to a table powered by a single power strip. The instructor would walk by, jerk the power strip out of the wall and sing "Save Save Save" some people got very angry with him for that

We were not happy to see that price but that machine needs to run all the time to make our production requirements so we had to eat the cost for a spare set.

It wasn't a fan. Especially since it was a Rapid move at around 300 IPM

I'm guessing the endmill had an issue with this????
