CamBam help (General usage) / Duplicate Co-ordinates after G2
« on: July 30, 2021, 00:23:37 am »
I have been experimenting with G42, cutter compensation, to establish the cut on my mill.

I instructed CB to generate code for the profile of a pocket with Tool Diameter = 0.

When I tried to run the code on LinuxCNC with the tool diameter set in the Tool Table, I got error messages and the code would not run.
Inspected the code and discovered that a number of G2 moves had the target co-ord repeated on the next line with a G1.

Generally, the repeated c-ords were slightly different, more or less digits of precision and roundings, all trivial differences.
Removed all the duplicated lines and the code ran fine.

I know that LinuxCNC calculates line-by-line the tool path using simple mathematics to allow for tool diameter.

Previous efforts along the same lines did not suffer the duplicates.
I assume LinuxCNC saw the trivial differences as intended tool movements and the tool path mathematics failed,

Can anyone shed any light on what I did in CB to initiate these duplicates ?

Keep well,
John (in Lockdown Sydney).

Installation Help / Lubuntu 21.04 - Correct Download to Install
« on: June 10, 2021, 23:38:50 pm »
Hi,
I have trialled CB in the past on a previous computer with Lubuntu 18.04, not sure what CB download was used.
Because of problems with the Lubuntu upgrades, I am forced to run the latest rolling upgrade, currently 21.04.

I have decided to permanently install CB, but not sure what download to use.

Because of backups being used to re-populate the folder system on the new computer, I have some CB files in various locations.
Should I remove all earlier CB remnants before starting the new install ?

Keep well,
John.

CamBam help (General usage) / Railway Wheels by New User
« on: June 16, 2020, 23:43:55 pm »
I want to make railway wheels ( 127 mm gauge loco ) about Dia 125 mm with spokes shaped to an oval cross-section.

I have a test version of CamBam running Ok, and the generated code being used on a turret mill with LinuxCNC.
My skill at 3D design is yet to be gained.

Can the full version (paid) of CamBam produce code for a ball mill from an imported STL file, or other popular 3D format ?

Great product,
Keep well,
John.
