 When I use the net command in my HAL file in LinuxCNC to connect a QtDragon pin (for example, net jogspeed_u qtdragon.slider-jogspeed-linear classic ladder.0.floatin-05) to a HAL signal, I get an error saying that the pin qtdragon.slider-jogspeed-linear does not exist. However, when I run the same command via the halcmd interface, no error occurs. What could be the reason for this issue?
 

using spindle-enable the output of lut5.0 seemds to remain resolutely False, despite the values of the input signals being correct

First, thanks for all the help.  This is my time LinuxCNC so, please bear with me.  My setup:  Rpi5 with SPI to a BigTreeTech SKR 1.4 (has the LPC processor) running Remora pulled from Github a couple weeks ago.  I got everything compiled and I think in the right place (I got a bunch of warnings on the SPI Remora compile but was told to ignore).  I figured the remora-xyz sample code looked like a good place to start.  The LinuxCNC Config Selector allows me to select remora-xyz and a window starts with axis.ngc.  *The problem is that the Emergency Stop button comes up pressed and it can't click it off*.  I have tried using the halmeter tool and found a variable called iocontrol.0.user-request-enable that I think may be relevant based on looking at the .hal file.  This PIN reads FALSE but very briefly flashes to TRUE, then back to FALSE when I click on the Estop button.  I as wondering if the remora-xyz example is actually trying to read a HW input somewhere on the SKR 1.4 board that I should be terminating correctly?   Any suggestions much appreciated.  TIA.
