General Mach Discussion / Scale Question

« on: October 30, 2010, 03:39:45 PM »

Having a problem with scale i think.

Ok heres what i have done,

In vectric Cut2d i have drawn a square 100mm * 100mm and exported it as  square.dxf,
I have then loaded square.dxf into Lazycam and then generated the Gcode, saved as square.tap
I have then loaded square.tap into Mach3 and run the program

If i leave scaling as 1.000 (default) it will cut a square over 200mm, i have got it to cut a square at around 105 - 110mm by setting the scale to 0.400. This seems wrong to me, any ideas whats going off?

Please dont tell me Cut2d is no good, i have just paid £111 for it and the wife is going to kill me when the CC statement drops through the door.

Thanks
Anthony.

Hi Dave,
Just been out and purchased that parallel card ( i  got the single port version though ) £30 from maplins.

It looks like it was a waste of money. The card itself works fine under windows 7 but what u cannot do in windows 7 is change the card to EPP and as far as i understand Mach3 needs it to be in this mode.

I have it installed, no errors reported in device manager but Mach will not control the CNC, maybe i have the wrong port address or maybe its the ECP setting?

Its currently listed in device manager as PCI ECP Parallel Port (LPT1) and if you look at the properties for the device it gives you no options to swap it over to EPP

I think this is a Windows 7 problem no the card, i have tried the latest win 7 drivers from www.Moschip.com and still no joy.

Thanks

Thanks for the reply.
Im not going to make any money from milling. the reason i purchased the cnc machine was to cut out parts for remote control planes that i want to make.

Would make life a lot easier if i could run everything from my main PC, its going to be a pain switching between them, but i do understand that its best to give the CNC a dedicated pc.

Just going off topic..
This PC has no parallel port on it, its the only reason im not using it to control the CNC. I have seen a PCI & PCIe parallel port card on ebay, these are going for £11 & £19, i dont mind buying one, but will it work ok with Mach3

Thanks
Anthony.

Hi, First of all sorry if this post is in the wrong place.

My question:
The Mach1Lic.dat file, is it a 1 use only? 1 install and 1 pc..

The reason i ask is, i have mach 3 currently installed on a friends pc, and he will want this pc back at some point in the near future, forcing me to get a diffrent pc to run mach 3 on.

I dont want to use the Mach1Lic.dat file and have Mach3 locked to his computer.

Could anyone let me know where i stand on this.


Thanks
Anthony.
