If you use pncconf to create your configuration, there a check box by the inputs
to invert them.

Steppers Not Moving / Mapped Wrong

Category: Basic Configuration

okay further update.

I got the estop signals to show up on Halshow. for anyone in the future having a similar issue. I needed to connect the ground from the power supply to the TB3 pin 12 (int common). From there i went 24v+ --> NC on the switch --> Common the switch -- > to the mesa. I am using simple two lead limit switches.

My next questions is how to invert the pin in the hal so that the machine will power on and honest think the limit switches are always being pressed.

I am also considering putting one more on the tandem second y motor so i can square the axis every time i home the machine. Does is this a good idea? seems like free real estate.

thanks again.

Limiting keyboard jog accelerations after 2.7.15->2.9.3 Upgrade

Category: Basic Configuration

Ive was playing with this recently, I think it is this in [TRAJ], and the default one says its specific to jog,


DEFAULT_LINEAR_ACCELERATION = 2.0 - In machines with nontrivial kinematics, the acceleration used for "teleop" (Cartesian space) jogs, in machine units per second per second.

Why does MOTMOD create its own threads?

Category: General LinuxCNC Questions

Ok, so it would be reasonable to assume that if I moved the rtapi call from motmod/tpmod to somewhere else I should not expect weird side effects since this is all done through the fairly standard RTAPI API.
One other question I have is, why is there a limit on the # of threads created and the order they are created in? Is this again a convenience/limitation made to simplify things or more of a deliberate design trade-off?
