New Project with Mesa 7I96 and THCAD-05

It seems you have one combined input for all the home and limit switches, which doesn't fit with having all the HOME and HOME_OFFSET for every [JOINT_n] set to 0.0
If doing automatic homing then it also needs HOME_SEARCH_VEL, HOME_LATCH_VEL, and HOME_FINAL_VEL for each [JOINT_n] and if you have combined home switches then you need to set the HOME so it has backed off the switch for that joint to allow the next joint to home.

Do you intend using a home switch/switches and have the machine move automatically to the home positions when commanded or is it intended to move the joints manually to position then home them?

There are no inputs or outputs to the 7i96 configured for any of the plasma functions, that should be done on the TB3 page:


Do you have an external EStop button? if so then it also needs to be connected on the TB3 page.

Could you also post the newmachine_QTPlasma.pncconf file which should be in the ~/linuxcnc/configs directory, a schematic of the system or a list of connections would also be of help.

You have selected the 16:9 layout so there should only be the four tabs as shown in your posted pic.

If you want the 4:3 layout, change this line in the ini file:
to:

The Home All button is missing because there is no HOME_SEQUENCE in any of the [JOINT_n] sections of the ini file.

Try changing this line in the ini file from:

to:

You have an external estop in your hal file so you would need to use that to get out of estop.

It is not recommended to use a GUI button as an estop but if you want to do that then you need to do a bit of HAL interfacing to get them both to play well together. That is not discussed in the QtPlasmaC docs as that can vary greatly with folk doing all sorts of odd stuff for estop. It should in reality be kept simple, mechanical and out of the GUI.

For testing purposes you could set ESTOP_TYPE to 2 in the ini file and change this line in the HAL file:
to:This would use the GUI button as the only estop.

QtPlasmac has no effect on homing and/or limits, that is all controlled by LinuxCNC. You can do homing/limits in any combination tht is valid in LinuxCNC.
