Continuous jogging runaway on X-Y when using joystick

[lorenzo535]

Version

2.1.5

Hardware / Firmware

GRBL 1.1

What happened

Jogging mode gets stuck when operating a joystick as an input device (xbox 360 gamepad), more precisely when input source is "analog jog" from analog joystick.

This happens following a prolonged jog command (i.e. keeping an analog joystick of the joypad deflected on a side for a while to produce continuous jogging): when the joystick is released, often jog mode remains stuck (highlighted in green in GUI) , no buttons on GUI are responsive; joystick as well is no longer responsive. Only machine reset or reaching hard stop can stop the motion happening and make GUI responsive again: this shows that GRBL controller is not hanged, but simply UGS stays locked in perennial jog mode.

This can also be reproduced if analog joystick is yanked from side to side (i.e. full left to full right deflection).

GRBL board used is ESP32 based with Grbl_Esp32 firmware.

Perhaps a simple fix would be to start a safety timer to kill jog every time a jog command is started: in this way either the user bringing back the joystick to center or the timer will ensure continuous jog is stopped, releasing UGS from its stuck in jog mode state.

How to reproduce

No response

Operating System

ubuntu 22.04

Anything else

Can be reproduced very often, especially if certain feed rates are selected: in my case for instance with a rate of 600 selected I can almost every time reproduce it by yanking left right on the gamepad analog joystick.

What is your configured maximum feed rate for each axis (output from the command $+}?

What feed rate have you configured in the jog controller?

[lorenzo535]

Runaway or jog mode lock is more likely to happen at feed rate 600.

Ok, since your jog feed rate is lower than the maximum rate the this is not the problem that I was suspecting. I can't reproduce this.

You could try and update to UGS 2.1.6 and see if that helps. The gamepad library got updated in that version.

[lorenzo535]

I'm sorry to report that the issue is still happening with my setup (which is rather simple) using UGS 2.1.6. I can't reproduce the behaviour easily, but it seems to happen if long jogs are commanded (i;e; staying long times with the gamepad joystick deflected) or when joystick inversion are commanded (i;e; full left to full right stick movement)
When this state is encountered UGS buttons are greyed out (stop, reset, ...), UGS is in "Jog" mode and a very slow jog runaway on one axis is executed by the GRBL 1.1 board. The only way to stop this jog lock state is to trigger a hard stop or reset the board.
