Re: Arc converted to straight lines.

It's good to see that Denford are taking an interest in this problem. I don't have a copy of QuickCAM 2D, but as far as I can see this problem is present regardless of the drawing package used. In the Autosketch DXF file the arc is clearly specified as an arc, not a series of arcs, series of straigh...

Will VR Milling 5 run on Windows 10

I've just tried to run VR Milling versions 5.51 and 5.61 on a Windows 10 PC. They start up OK, but as soon as I try to run a .fnc file in 2D simulation I get the error message "External exception 80000003". The program then locks up and the only way out is to start Windows Task Manager and kill it f...

Re: Arc converted to straight lines.

I wish Denford would sort this out too. I also wish they'd sort out the problem with drilling holes when importing an imperially dimensioned drawings which has been outstanding for nearly three years. http://www.denfordata.com/bb/viewtopic.php?f=2&t=3903&hilit=DRILLING+HOLES VR Milling 5 is a produc...

Re: Microrouter (2006) No movement all three axis

I'm not an expert on CNC electronics, but I do have an electronics background. With power off all relay armatures should spring back to the released position. It's possible though that a relay could be powered from a charged capacitor, but it should release once the capacitor is discharged. Dependin...

Re: Errors in CNC Programming Help File.

Clicking the info button to close the info works fine if there no error present. However if I try it after the .fnc file (attached to an earlier post) has been run in 2D simulation and returned an error the software locks up and I have to use Task Manager to close it.

Re: Errors in CNC Programming Help File.

I am using a 3mm dia slot drill. I've attached a copy of the fnc file which causes the error. It's possible to avoid the error by inserting a G40 command. This is a problem with the Help File, which doesn't state the need for a G40 command, rather than with the software. I've also noticed. 1. Double...

Re: Arc converted to straight lines.

I have tried both your files, running them in 2D simulation and manually checking the GCode. In both cases the arc is reduced to four straight lines. Tried some experiments and found that VR Milling works OK when cutting for example an 8" radius semi circle. It uses G2 instructions to do this, produ...

Re: Arc converted to straight lines.

Hello and thanks for your efforts. The odd dimensions are down to the original paper drawing having fractional imperial dimensions. I redrew it using imperial decimal dimensions. The curve at the top has a radius of 8 inches. I convert all imperial drawings to metric before importing them into VR Mi...

Re: Arc converted to straight lines.

You'll find DWG and DXF files in the first post in this thread. Most drawing packages should open these. Dimensions aren't shown, but are embedded in the files so you should be able to add them. Dimensions are metric. It'd be interesting to see whether another CAM package does a better job of produc...

Re: Arc converted to straight lines.

In the end I wrote my own G Code for the part using tool offsets and arc drawing commands. The actual cutting part is only about five lines which is far less than VR Milling produced when importing the DWG file. The part was successfully cut and has a nice smooth arc.

Errors in CNC Programming Help File.

The example help file for the cutter compensation commands G40, G41 and G42 doesn't contain a G40 command. I tried to modify the example programme to suit my own requirements and couldn't work out why I kept getting an error message. Inserting a G40 command cured this. Also line 0030 appears to be w...

Re: Arc converted to straight lines.

No matter which boxes I tick VR Milling converts the 8 inch radius arc to four straight lines.

I'll have to try writing my own G Code.

Re: Arc converted to straight lines.

The help files provided with VR Milling 5 are very good when it comes to G Code. I find I can get on OK just knowing G0, G1, G2 and G3. I suspect very few people actually write G Code directly these days, just as no one constructs a web page by writing directly in html. Instead they'll use some kind...

Re: Arc converted to straight lines.

Thanks for your reply. Before posting I actually plotted the G Code on graph paper. Old fashioned, but it works. The G2 commands in the .fnc file are actually used to "ROLL" the 3mm diameter cutter round the corners of the part. Hence I=1.5, half the cutter diameter. Without these G2 commands the cu...

Arc converted to straight lines.

Using VR Milling version 5.59.0.666 with Triac PC. I have attached .DWG and .DXF files for the same part, an oblong plate with one side being an arc of 203.2 mm (8 inch radius). If I import either of these files into VR Milling, use it to create a .fnc file and then cut the part, the machine cuts fo...

Re: Setting work piece zero VR5/Micromill

I use VR Milling 5. When transferring the machine's X, Y and Z coordinates to the work offsets menu the default is to transfer the coordinates without changing them, so in the case of X and Y the work offsets will be aligned with the CENTRE of the cutter. The boxes to tick are along the top right of...

Deleting work offsets.

In the work offsets window, right clicking on an offset description gives a drop down menu with an option to deleted the offset. This option doesn't work and nothing happens. The "red cross" icon does delete the offset description though. Just drawing this to the attention of the software developers.

"Advanced" option?

In the "Offsets / Tooling" drop down menu there's an option "Advanced" which can be ticked and unticked.

Can anybody tell me what this option does?

Thanks.
