Hi
Yes G94 return to linear mm/min and angular deg/min. G93 is really useful when doing 4th+ axis moves...
For the #5 minimum log radius, I don't think it is used at all since it is not required to define the move.

The CAM software knows at what radius the tool is working. The move is defined with the G93 G01 X Y Z A with the parameter F#. The CAM software (Fusion 360 in my case) compute the appropriate F#=(1/x min) inverse time to complete the move necessary to have a constant cutting speed with respect to what radius the tool currently is. The larger radius the tool is working on the part, the lower the angular speed is needed to keep linear speed on the tool which means longer time and smaller F#. With G93 you can have simultaneous linear and angular motion with the correct linear speed that depends on radius. This is computed by the CAM software and not the CNC.

Hi Lindo,

Ok, I will indicate in the future.

Ytliu

Thank you, I currently use G94

If and when future new versions are "critical" to the well being of the controller, please indicate
download and Instal version as Important.

Best regards

Maxx2000:
When the G93 mode is specified, the #5 and #6 settings are ignored.
G93 and G94 belong to the same group of instructions for setting the feed rate mode. G94 to start the units per minute mode. G93 to start the inverse time mode. The default is G94 mode.

Lindo:
Upgrading will not affect the previous features. If you don't use the G93 command, you don't need to upgrade.

Ytliu

Is it necessary to keep updating to the new versions.
I am getting a little confused.
These updates contain the previous versions ?
I am using currently 2019-05-21-110 NOR
Back lash DIR display works very well.

Thanks

I'll duplicate the questions I asked on Facebook here. I think it will be useful here.
1. how the introduction of support G93 is combined with the parameter # 5 "minimum log radius of 4axis machining?
2. Does the G94 command cancel the effect of the command G93?

Ver: 2019-05-27-111 Description:
1. Increase G93(inverse time feed rate mode) support.
In inverse time feed rate mode, an F word means the move should be completed in one divided by the F number minutes.
For example, if the F number is 2.0, the move should be completed in half a minute.

Thanks ! I made a mistake missing G1.
However same issue with G93 does nothing

not required for DDCSV
