You can also disable motion by setting 'motion.enable' to FALSE but machine state will still be switched to Off.

the relevant code section is here:
github.com/LinuxCNC/linuxcnc/blob/master...tion/control.c#L1465

If it is possible to do this for a specific joint during program execution would have to be explored. I expect that the interpreter would need to restarted at the very least.

No, I added my pins and linked them to jog_increments widget:
[code][code]pin = QHAL.newpin("mpg.mpg-inc.1", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(1))
pin = QHAL.newpin("mpg.mpg-inc.2", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(2))
pin = QHAL.newpin("mpg.mpg-inc.3", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(3))
pin = QHAL.newpin("mpg.mpg-inc.cont", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(0))


[code][code][code]But I would like to be able to enable/disable the increment selection from the screen, only showing the current value. Perhaps there is a way to disable the drop-down menu or something like that.

Changes in configuration files generated in pncconfig for 7i76 to 7i78

Category: Configuration Tools

Thanks for the answer. There is one 7i78 -> P1 connected to 7c81, one optocoupler board on P7 and when I know how to do it, one 7i73. Why not pncconf for 7i76 but G540? It's more similar to 7i78. So with that encoder it means that it doesn't matter where and what encoder I choose, just change the name in .hal according to your example? Sorry for the question, will it be clear that it is a spindle encoder? Although it may be a stupid question, 7i78 has only one encoder and it is for the spindle... In the manual for 7c81 the encoder is marked as ENCA+, ENCA-, ENCB+, ENCB-, IDX+, IDX-. I don't know how it will look in .hal, because pncconf does not have the option to configure the 7c81 board. Well, with the list of parameters, it's clear, but as I already wrote, I'm completely lost and it's going slowly :).

MPG and analog command config issue was created by vibram

MPG and analog command config issue

Category: Basic Configuration

Hello I try to setup a mill with all servo drives run with analog command and it's working fine.

However, now I try to setup a MPG
after customizing the HAL file, here is the situation:
the MUX is correctly working for the scale and the axis.x.jog-scale is correct (value from 0.01 to 1mm)
axis.x.jog-enable works fine, same for Y and Z
axis.x.jog-counts works fine, I can see the number of pulses moving when I turn the handle
axis.x.jog-accel-fraction is set to 1

When using Axis interface with the and - button, it works fine
However; when I turn the handle, the axis is not moving at all, I don't have any error message.E-stop is off and Toggle Machine power if ON obviously. 

Any idea what could be the issue?
thank you

There is no way to read an SDO value into hal as far as I know.
But as you say it wouldn't be too hard to write a user-space hal component in python
the runs the command "ethercat -p n upload 0x2608 0", parses the output and returns a value.
I mean, in principle.

7i76eud.bin firmware did the trick. Interesting this firmware does not show up in the MesaCT list when using the Configuration Tool. It was in the /lib/firmware/hm2/ folder but it was not showing up in the drop down list.

EtherCAT servo as main spindle

I noticed that if I disable the machine the joint.0.motor-pos-cmd tracks the joint.0.motor-fb. So I set up a new hal file with only one cia402 and no cia402pv. Because you can't change the mode of the cia402 while LinuxCNC is running, I change between CSP and CSV by writing directly into the mode of the frequency drive via EtherCAT.

In CSP mode cia402.0.pos-fb -> joint.0.motor-pos-fb. 
In CSV mode joint.0.motor-pos-cmd -> joint.0.motor-pos-fb.

So I have no following error in CSV mode, but I need to change the position before changing from CSV back to CSP or I can turn the machine off and back on again. I built a network with mux2, oneshot and flipflop to toggle the machine for a very short amount and to reset all my mode switching logic. This works surprising well and isn't noticable.

I know that this soultion is not good and only works for my usecase because I only have one servo and nothing gets interrupted by the power cycle.

The bigger problem is that my gcode file gets stopped aswell and I can't resume. Maybe there is a way by tracking the executed lines and then starting from there... But I'm not happy with the power cycle solution in the first place.

Is there any other situation where joint.0.motor-pos-cmd tracks joint.0.motor-fb?

Looks like you got the pin name wrong. Try removing the 'gladevcp.' at the beginning.

Ethercat drives not responding, mesa error finishing read

I figured it out. The manual doesn't explicitly mention SDOs but it does say whether an index can be assigned to a PDO and I ignored that information the first time around.
260B, 260C, and 260D cannot be assigned to a PDO.

Is there another way of getting this information into HAL, or do I need to write a custom component?

Output from "ethercat pdos" in attached file.

0x2605 works just fine: that's the DC link voltage and I can read that from all 3 drives.
0x260B does not.

The drive manual doesn't discuss SDOs, or whether some data index is a PDO or SDO. I would hope a temperature sensor would be continuously readable, which would require it to be a PDO.
