OneCNC Series Updates

This is a history of all OneCNC updates.

You may notice sometimes there can be a jump in version numbers.

This is due to intensive and continual internal testing where we thoroughly test versions before releasing proven functional updates.

To download updates, see our OneCNC Updates page.

OneCNCXR8 Release 62.81

OneCNCXR8 62.81 update includes many adjustments and updates and the main ones are listed below.

Mill Profile
Some users we notice use drill for a chamfer tool but OneCNC likes to use the right tool for the job.

Adjustment was made to the profile function so that if a user uses a drill for a chamfer tool it does not hang.

Mill profile
Mill profile was again adjusted with wall taper and ball end mill.

Layer function was adjusted to prevent duplicate layers being created by editing toolpaths

C Axis Face Toolpath
C Axis face tool path function was adjusted to make sure the function was reset when changing to a 4 Axis full function.


When entering tool sizes in the OneCNC tool library it is important that you enter the correct values to obtain the correct results in precision machining.

You will note that that entering tapered tool data the diameter of the tool is the diameter at the tip of the tool to be entered in the tool diameter.

We show an example of a SandviK tapered ball mill with a nominal 4mm ball but the diameter at the tip is actually 3.80 mm.

The 3,80mm diameter is the diameter that you would enter in OneCNC for this tool.

Fortunately SANDVIK engrave the diameter on the tool.

If the tool is not engraved you could draw the tool in OneCNC using angled lines tangent to the ball and obtain the diameter from OneCNC drawing at the tip..

OneCNCXR8 Release 62.81 is now available in the OneCNC Update Server for all licenced OneCNCXR8 users.r.


OneCNCXR8 Release 62.80

OneCNCXR8 Release 62.80 is now available.

Z level rough

In the previous release OneCNC users were reminded it is preferable to make the top of the job the Z position in the tool clearances dialog.
This also applies to the plane setting on top of the job in the case of multi axis situations.
Some users use the bottom of the job that Z position in the clearances dialog then set the clearances manually.
Some users put the plane on the bottom instead of the top and also set the clearances manually.

We have made further adjustments to assist users that use of that type of setting.

Z Level Rough Rest machining
Z level rough had an adjustment to the rest machining functionality of the 3D rough as it was not working in some settings..

Independant Scaling
This function was adjusted to support the independent scaling of points.

Japanese language was updated.

This update is now available in the OneCNC update server for all licenced users.


OneCNCXR8 Release 62.77

OneCNCXR8 Version update 62.77

OneCNCXR8 Release 62.77 contains many adjustments which we have detailed here.but first we have a reminder for all OneCNC users.

Special Note and Reminder to all OneCNC users.

When using any Stock Model Toolpaths the top of the material top Z (top of job) must always be set correctly.

Although this is a reminder but has always been the requirement in all versions of OneCNC in the Tool Clearances dialog material top setting.

This not only controls all clearance values but also controls the depth values of pockets profiles drilling and all depths of the stock toolpaths.

This shows a typical part and the arrows depict the Material Z Top

This release includes many functional adjustments and these are main ones.

Help File
New updated English help file and tutorials.

Was improved to prevent Invalid entity to cause printing to fail.

Z Level Rough
Z level rough toolpath improved to prevent not being generated

Engrave Simulation
Engrave tool simulation was improved.

Thread Cycle
Lathe thread cycle thread length Z positive direction was corrected

Chinese language updated
Japanese Language updated

HS Pocket
HS Closed pocket was adjusted to prevent being generated as HS Open if material top was set Z positive had further improvement. Changes were made to the offsetting method which changed the behavour of the top edge of the pocket including the top edge finish when used..

Mill Profile
Mill Profile using bullnose tool set to rough depths taper angle was corrected together with improved behaviour method of starting the top edge of the profile.

Mill Profile
Mill profile tool tip radius offset was corrected and further general behaviour improvement was made to the top edge of the profile.

Details of the new Pocket and Profile functions

Boundary behaviour changes are shown in the following graphics.

When using any stock toolpaths one of the most important value in each function is the top of the Job Z value.

This must always be on top of the Job

It can be possible to have the boundary on another Z level but the top of the job must always be the Z value used in the tool setting dialogs in OneCNC

This first graphic shows a Tapered Ball Mill being used to pocket and finish profile a pocket.

pocket 5

OneCNCXR8 supports standard style square end mills, tapered tools of square end ball nose and bullnose styles.

Users need to be aware that some of these tools the major diameter of the tool will often be outside of the pocket or profile boundary.

This of course depends on the tool sizes and lengths compared to the pocket or profile being machined.

pocket 7

This shows a tapered wall pocket using Bullnose End Mill using rough and finich parameters.

pocket 8

Shallow pocket where the tip radius of the tool is larger than the pocket depth the edge of the tool being used will now cut to the boundary.

pocket 2

This shows more clearly the pocket depth being less than the radius.

pocket 3

This shows a shallow pocket with a profile finish using a square end mill and a profile using a ball mill.

pocket 1

Be aware that in OneCNC many tools protrude beyond the boundary of the pocket or profile functions.

Ball End mill where the tip radius is less than the pocket or profile depth or the major diameter of tapered end mills often esceed the profile boundary..

High Speed pocket is not recommended for a shallow pocket with a large tip radius.

A better selection would be a Traditional Pocket or Zig Zag pocket styles with finish profile setting.

If you do use the HS style for this shallow depth pocket there will be a message to check the simulation.

HS style may not provide a suitable finish for a shallow pocket where the tip radius is greater than the pocket depth..

pocket 6

Here are other typical examples of tools with the major diameter exceeding the boundary.

Tapered Ball End Tool

Tapered Bullnose Tool

There are many stock toolpaths that can have overhang including chamfer tools.

Model toolpaths have many more situations similar.

This is the reason all toolpaths should be simulated before posting the file to the machine.

This graphic shows a chamfer tool.


OneCNCXR8 Version 62.73 is now available in the OneCNC Update Server for all licenced OneCNCXR8 users..
