    Re: jerky

    Look at G93.

    A good CAM system with rotary axis capabilities should be able to do G93 moves, which are Inverse Time Feedrate moves. They work by completing a combined rotary/linear move in a...

    Re: Tool Table

    That sounds like the answer.

    I have a controller with a valid license, but I'm running in simulation mode on a different computer at home.
    I'll try again on the CNC connected computer.

    Re: Tool Table

    Here you go.

    Under the Parameters tab, I changed the tool material from Carbide to HSS and it became 'greyed out' after that.

    Thanks for that.

    Something else I have noticed is that if you make changes under the Speed & Feed tab, then eventually, the edit fields 'grey out' and become uneditable. Only a restart of TNG...

    Feature Request for Lathe.

    Could you consider adding 'peck turning' to TNG2 please?
    It's good for preventing long & stringy swarf being created by certain materials such as copper or aluminium.

    Thanks, Martin.

    Re: fusion 360 planet cnc turning post

    Go to Settings, under User Interface, select 3D. Scroll down until under the Properties heading you find the Show Offset tick-box. Put a tick in it and the display should be as you want.

    Edit Causes TNG2 to Freeze

    I'm learning to use Deskproto, which compared to my other CAM software creates many short G01 moves and so files are much bigger.

    Re: The surface has facets

    Full steps and half steps are quite 'rigid', but when you try to go much finer between steps things get a bit 'springy' - they don't lock as tightly as full steps.
    You could use finer pitch screws...

    Just try something like G64 P1 and see how it performs.

    Check the Gcode manual the comes with TNG for more info.

    I think you'll be getting a kind of 'staircase' pattern because despite having your motors set to micro-step @ 4000 over 5mm, in practice you will probably find they can not dynamically hold these...

    Re: TNGv2 and G64

    Yes, I read your reply on that thread, so I know that, but if G64 isn't activating because you haven't entered a P value, then it appears that it's not working at all.

    Re: jerky

    Actually, there might be a bug in the G61/G64 code because G64 seems to be ignored if you swap between these two gcodes.
    However, G64 does work straight after restarting TNG, but not after going to...

    Re: jerky

    Try including a G64 command at the top of the program. If your machine defaults to G61, then you will get stuttering - check out the difference in the included gcode reference.
