Interesting pendent issue.....

I've got a vista pendant too, but I haven't run LCNC programs enough that I've noticed it yet.

Possible to auto-force it in to manual mode after a program ends?  Maybe connect halui.program.is-idle to halui.mode.manual through some logic that defaults to manual mode, but permits MDI mode if you want it?

That is a thought, I may look into that. I have not had time to go out and fire things up and see if the work around works like he stated.

Well I am back at trying to get some of the issues I have run into with the move to 2.8.

Even with Vista's response to toggle it to manual does not work. Once the machine has been in automatic once the pendent is a paperweight. I have tried to get back in touch with Vista about there work around not working and they won't respond.

Or the other option is ditch the Vista pendent and find another solution.

I have a P4SE and early on I had a similar problem except it seemed to be related to static electricity. I had foam mats on the floor and I had one instance where the pendent would work fine but as soon at I put my foot on the foam mat it would stop working and go back to the screen that it is at before LCNC starts. I eleminated the mat. I also installed an active repeater cable since I had to extend my USB cable connection about 6 foot. I am now using the P4SE with 2.8 with no problems. When I first switched to 2.8 back in Jan 2020 I had some issues and had to make changes to the vc-p4s.hal file. I shared these changes with Vista tech support and they said that they had updated the file on their site with the changes. I am running the lastest LCNC 2.8.x version and using the QTDragon UI on Linux Mint 19.3. I recently tried Debian 10 and it worked there also.

I'll have to try connecting to one of the active USB extensions. I thought I had it on there now, but I'll have to go out to the shop to verify. I'm right on concrete with no mats,

I have still been using Axis as I haven't had the time to get through the little changes I need to for QT Dragon to work the way I need it to ( like touching tools off) and some other odds and ends. I really like QT Dragon alot.

I really like QTDragon also. I am using an M6 remap with a mix of fixed length tools using TTS tool holders and variable length tools like drills and taps. I also used a 3D probe and toolsetter. The variable length tools get measured right after a tool change and fixed length use the length from the tool table.
