Spindle inhibit while probing

Did some new entrys in the axisui user_command_file today, with some (for me) useful additions:

-Clear the Info notifications, if 5 items reached. Leaving the Alerts untouched. It was hiding some important area of my PYVCP sidepanel when the stack of messages was rising.

-Automatic spindle inhibit when probe is in spindle, and set S0 M5. As any input of S and M3 M4 while inhibited, spindle will instantly start, after spindle.0.inhibit is set false.

Interresting, when a pyvcp panel is in the configuration and a halpin is created in the usercommand file, eg. 'comp.newpin("tch", hal.HAL_BIT, hal.HAL_IN)' after a long search i found it as 'pyvcp.tch'

prob_in_spindle = 0
def user_live_update():
	global prob_in_spindle
#PROB_S0
#PROBE = T999
	if s.tool_in_spindle == 999:
		prob_in_spindle = 1
		hal.set_p('spindle.0.inhibit','1')
	else:
		if prob_in_spindle == 1:
			prob_in_spindle = 0
		hal.set_p('spindle.0.inhibit','0')
#Clear INFO notifications if >= 5 reached
	if len(notifications.widgets) >= 5:
		hal.set_p('axisui.notifications-clear-info','1')
	else:
		hal.set_p('axisui.notifications-clear-info','0')

It made me also think about the polling cycles, compare 'user_live_update()' and a userspace Python component with 'time.sleep(0.001). The results are average 51 or 941 cycles / second on my machine.

Hi

I have do something similar with my config but rather than inhibit spindle i have choose to cancel the whole operation if probe is connected when you try to run spindle.

Imo using inhibit is possibly dangerous...

Here is the link, Phil helped me with his problem recently, you have to change a part of axis, and then you can create comps in usercommand, and use a pyvcp at the same time.

From:

comp.setprefix("pyvcp")
To:
comp1 = hal.component("pyvcp")

From:
vcpparse.create_vcp(f, comp)
To:
vcpparse.create_vcp(f, comp1)

Thanks for reply, i will try this later on the machine.

Tried to solve the silly idea, inserting a mdi command in usercommand file, just to run into another problem. I think i will close the workshop for the rest of this year...
