Help with QTplasmaC

That at the end will decide if you can jog or not while in Joint mode before homing the machine.
I always set it so it can not jog Y (tandem) axis without homing, but X and Z can be jogged before homing.

This has rapidly declined. That is not really what kinstype=both does.

Using Axis as an example, the following in an .ini file will show Axes X Y Z as needing to be homed:







The following in an .ini file will show Joints 0 1 2 3 as needing to be homed:







Adding a negative sign to the joint HOME_SEQUENCE for the corresponding joints that make up an axis will prevent jogging before homing... This is true whether or not you have set kinstype=both or not.


With kinstype=both:





Without kinstype=both:

This has changed. I dont know when but it definately wasnt like that before.

Thinking about it . It might be a 2.8 - 2.9 thing

Snowwy, nicely explained, thank you.

I upgraded to 2.9 on my main machine to do testing/help develop QtPlasmaC. I was on 2.8 previous to that, and this is how it was for me on 2.8 as well.

Perhaps it was a 2.7-2.8 thing? Either way. Use it to your advantage

This is a bit OT from Clives thread but hopefully this will clear up some confusion.

QtPlasmaC was designed with the end user in mind. I don't believe that end users are interested in joints (well maybe some type of joints ) , all they want to do is move the torch left, right, forward, backward, up, or down. For this reason so I decided to hide the joints and only show the axes.

QtPlasmaC has no affect on homing and/or jogging, that is all controlled by LinuxCNC.

If a gantry machine is setup properly the tandem axes will have a negative HOME_SEQUENCE. LinuxCNC will not allow joints with a negative HOME_SEQUENCE to be jogged unless all axes are homed, for this reason QtPlasmaC shows the GUI jog button for any axis with tandem joints as disabled until the machine is homed.

If an attempt to jog is made using keyboard jog keys on tandem joints with an unhomed machine, it will result in a popup error message from LinuxCNC, I imagine the same error would happen for an MPG jog.
