i have struggled to find out what "mode" my drivers run in. as far as i can tell there is no option to choose between the torque or velocity. 

My drivers are Advanced Motion Control (branded as Precision Valve & Automation) B12A6F-PV2. i have not been able to track down any manual or documentation for this specific drive, but i do have a general setup guide from AMC which covers this era of hardware and gives me some idea of how to operate it.

However in re reading the above documentation i think the dip switch labeled "open loop" on my drive (which is switched off) is the mode change switch, with "open loop" being velocity, and the alternative being torque. Pages 14 - 16 have the modes of operation, but my drives do not have all those options. below is an image of what i have showing the pots and the dip switches.

we do now have rpi4 apt installation, just need to follow the installation guide for it. it is built in our buildbot.

ok i have reworked keyboard jogging, it now has the following functionality and is available in the latest apt install for develop branch.

ini settings:

KEYBOARD_JOG = true
(turns keyboard jogging on)

KEYBOARD_JOG_SAFETY_OFF = true
(removes the need for the control key)

shift key + jog key will give you rapid jog speed (works in safety mode and normal mode)

jog key gives you jog speed with jog feed override slider percentage applied


Probe Basic Lathe uses the following for keyboard jogging:

Left and Right arrow keys for Z axis
Up and Down arrow keys for X Axis

(in the display section, set one of the following entries only, LATHE is for front tool post, BACK_TOOL_LATHE is for rear mounted tool post)

[DISLPLAY]

LATHE = 1
(this makes X Positive direction jog key the down arrow key)

BACK_TOOL_LATHE = 1
(this makes X Positive direction jog key the up arrow key)

I think these all make sense and follow the linuxcnc std a little more closely!

Best Regards,

Chris

Ive got a single X axis going!

I used info from here...    forum.linuxcnc.org/ethercat/54965-stepperonline-a6-servo




My main problem this evening was installing the cia402  hal correctly. I ended up just making a dedicated folder home/linuxcnc/cia402 and placed cia402.comp there. 

 Then I opened the terminal and  >>     sudo halcompile --install cia402.comp  


that worked!

To be honest. I think I would ad a lever and a switch for homing (plus index). But it depends. Maybe you want to have it as original as possible?

For homing I would meassure how much the resistor value changes for one motor revolution. After that one can think of solutions. That said. It would be a good step to identify the ratios of the axis.

For the needle encoder. Plug it to a mesa card (first test with bench power supply and oscilloscope) and turn 10 revolutions....

I can assure you a VNC of any kind is not included in the distribution ISO.

I don't think there is a prebuilt Probe Basic for the Pi. You would need to build from source

Just recompile it.

The whole idea of a more industrial gui is difficult to implement/deploy on linuxCNC since theres not really a premade unit with a unified set of controls. Everyone is going to have different physical setups. I think lots can be done in hal already but some stuff is hard to do, like the ability to not need a mouse by default. Axis is already pretty close to technically not needing a mouse to operate, but it lacks features. The peripherals needed to run axis (file manager, tool editor, gcode editor) kill the whole thing also.


second for the parameter page, I made an attempt to make a parameter display for axis, based on qtvcp code, but I am stuck on how to change them.
github.com/cakeslob/regularmac_800/tree/offset
Ive made good progress making the axis gui more fanuc like, PhilC has helped me a lot, and I use lots of stuff from qtvcp because it has all the features I want. I post this to show its not all gui whining but computers are hard.

 
 

by computer gui standards, its pretty shit, and its hard as all hell to do stuff, and this is the "new", they went with a dark mode.
But Cnc workflow wise, its very fast, stable and safe, with very little screwing around. Its annoying compared to the LinuxCNC guis, but the workflow is less clumsy.
they always blast me for this in irc
 

Wow that was simple lol. Thank you I also added M50 to the preamble to allow adaptive feed. Just to be sure but working great now. Thank you

Yes, it is still disconnected because I am waiting for the installation of the fast overvoltage electronic efuse TPS2596

To the 5V Mesa power?
I do not think any fuse is faster than silicium/silicone inside the chips.
Put a switch on the primary side of the power supply.

Are you sure the drives are in velocity mode?

If they are in torque mode, the tuning is completely different.

In velocity mode, the motors should strongly resist any attempt
to rotate the shaft (even with P=0)
