  1. Unfortunately Roger passed away last year.  Eric at Prototek and Mick from Mastercam teamed up to update his file for Mastercam 2021 though.  It can be found here http://forum.mastercam.com/Topic27430.aspx

     

    I've been using the Prototek tool for a few years but before that I did it without.  I can't remember all the details but I think you can just move the shared folder to the network and then change the configuration file on each computer to its location.   The Prototek tool is probably the safest way though.

  2. Our DNC computer still has a serial port so we haven't run into this yet.  You can get PCI to serial port add on cards.  I'd probably try one or two and see if that works.  There might be issues getting some to work.  Years ago I had trouble with a PCI to parallel card not working with Surfcams hardware key.  Changed to a different brand and it worked.

  3. I run a Kitamura with a Fanuc 16i control using G54.2 and can probe the part in X,Y,Z, and C axis.  G54 is set to the machine center of rotation.  I probe the part position into another offset and I have a macro program that does the math and transfers the correct values into the dynamic fixture offset.  I have my post setup to call the macro program at each toolchange.  On my machine I need to use G54.2 for 2 and 3 axis toolpaths but for full 5 axis I need to use TCP (G43.4).   For G43.4 I can simply probe the value into a offset.  I have my post setup to post out G54.2 or G43.4 depending on the toolpath being used.  The way I'm setup I can probe the part position into any offset between G55 and G58 and run the program as posted out of Mastercam.

  4. I recently had a part were the lead in would work but the lead out would cause it to stop short of the edge.  Playing with the sweep angle on the lead out would get it to work in some places and if I tried enough sweep angles it might have worked but simply turning off the lead out gave me what I needed.  With lead out off it still did a 90 degree lead out.  I'm at home right now so I can't look at your file to see if its the same problem I was having.

  5. I'm running a Kitamura 5 axis with a Fanuc 16i-MB control.  I use dynamic fixture offsets for all 3 axis toolpaths and TCP for 5 axis paths.   I've got the post outputting the correct one based on the toolpath type.

    The M1154 is one of two custom M codes calling a program that does a G10 parameter write.  We use one before drilling and the other before milling.  It was created before I started running this machine so I don't really know what it is doing or if it has anything to do with dynamic fixture offset.  I don't see it outputting in the 5 axis code making me think it has something to do with the dynamic fixture offset.

    why are there two different swarf tool paths??

    My guess is one is an old Mastercam created path and the other is the newer one made by ModuleWorks.  Sometimes one works better and sometimes the other.   There are even more surface project toolpaths.  I've found three of them.

  7. It is hitting a travel limit on a rotary axis and needs to spin it around to continue.   I try to find a way to fix it if possible but I think I've run one a couple of times with that warning.  It is likely going to spin the rotary at max speed when it gets to that point.  Depending on the machine it might be ok.  My machine has the TCP option and I don't think I would want to try it on a machine without it.

    What were the clock speeds and Ram specs? While Im leaning to this to be true, Being a ryzen guy myself... Im curious how Ram timings and speeds are in effect/different in your scenario ... 

    I9-7900X has 10 cores and a base speed of 3.30 GHz and a turbo of  4.30 GHz

    I7-8086K has 6 cores and a base speed of 4.00 GHz and a turbo of 5.00 GHz

     

    The ram in the I9 computer was 64 GB of Ballistix Sport LT - DDR4 2666 (PC4 21300) - Timing 16-18-18 - CAS Latency 16 - Voltage 1.2V

    The ram in the I7 computer was 32 GB of Corsair Vengeance LPX -DDR4 3466 (PC4 27700) - Timing 16-18-18-36 - CAS Latency 16 - Voltage 1.35V

     

    If i understand it correctly the faster speed of the ram in the I7 computer would only matter if it was overclocked.

  9. We recently started having the company that manages our network do custom build for us.  I prefer them over the Dell computers we used to buy.   Dell will actually do more then what there workstation configuration tool on the website shows.  On the last Dell's we ordered we were able to get I7 processors but had to call them.
