[LinuxCNC/linuxcnc Issue#315] Stepconf: charge-pump.enable pin not connected to the correct signal if an external e-stop switch is used. About GRBL HAL

Issue #315 | 状态: 进行中 | 作者: ReeseWang | 创建时间: 2017-08-06

标签: stepconf

Here are the steps I follow to reproduce the issue:

1. Generate a machine config with the stepconf file below:
https://github.com/thuSkywalker/syil-x5-linuxcnc-config/blob/dd45ce7ea70a89a7dca43d7cb972000c5a38544f/Syil_X5.stepconf
Note that an input of parport is configured as e-stop function.
2. The generated machine HAL file should be similar to this:
https://github.com/thuSkywalker/syil-x5-linuxcnc-config/blob/dd45ce7ea70a89a7dca43d7cb972000c5a38544f/SyilX5/SyilX5.hal
3. Start LinuxCNC, turn on the Machine Power in axis GUI, attempt to jog the machine.

This is what I expected to happen:

The charge pump is enabled, The machine moves.

This is what happened instead:

The machine doesn’t move because the charge pump isn’t enabled.
By looking into the Syil_X5.hal file (link above) I found the enable pin of charge-pump is still connected to the estop-out signal (line 10), the same as when I didn’t configure an e-stop input in stepconf. It should have been connected to estop-ext as I’m using an external e-stop switch and I did configure an e-stop input in stepconf.

Seems that the e-stop signal changed from estop-out from estop-ext, but charge-pump.enable forgets to follow.

I tried the config created by the stepconf file, and I agree that the behaviour seems unexpected.
However, clicking the E-stop release (X) button in Axis does appear to turn on the charge pump.
(the unexpected behaviour is that external e-stop activation on pin 11 does not turn the charge-pump off.

@andypugh In my Axis 2.7.11 the e-stop button is always not pressed (with the configuration above), and the chare-pump.enable pin is always 0 no matter what I do.

Have you tried pressing the button? (on-screen?). What is the value of your pin 11 input?

@andypugh Yeah, sure, tried everything I could. My pin 11 input is high in the normal state (non-estop), low when the e-stop button on my machine is pressed.
