I think that this would best be done in the GUI.
Which GUI are you using?

You _could_ use the "message" component to pop up the message when any HAL pin indicates "homing" but blocking the homing until the OK button is pressed would be harder.

linuxcnc.org/docs/stable/html/man/man9/message.9.html

A custom python component might be able to monitor homing state, pop up the message and also inhibit motion until OK is pressed.

I don't know if set_feed_hold or maxvel affect homing moves.
linuxcnc.org/docs/stable/html/config/pyt...command_code_methods

It _might_ suffice to automatically send a tool unload as the flag to indicate that a tool length check is needed.
Then maybe remap the S-word such that the system aborts with a message if there is an attempt to start the spindle when the tool-number is zero.

It might be possible to detect a tool change by watching the spindle encoder position. If it moves with the spindle off, then it's likely to be a tool change (especially if it moves backwards)

Can i use this ac servo motor for 
building my mini diy linux ethercat CNC?
 

Is it possible to have a "ok" confirmation warning pop after pressing any of the homing buttons in the GUI?
Something like:
"Ensure no rollers are installed before homing axis!"
                                 Ok

 

rodw You are probably also aware of Collective Shout's line of crap that is simultaneously going on. I'm not sure how much
more I could say before being labled a conspiracy nut if I'm not considered one already. It's also another reason I
don't like Windows / Microsoft. I would say it's like the movie 1984 except this kind of thing has happened repeatedly
throughout history by world powers. 

Maybe I should be asking a different question.

If I were to change the "setp stepgen.4.velocity-cmd 20" line in my HAL file, while AXIS was running; would it make any difference?

Is the HAL file used while the AXIS CNC program is running OR is it only used to set up the machine during start up?
What are your thoughts?

Thanks

Hi. Do you have some code with this subroutine working? If possible, can you share? I use Notepad++ to make sure the file is in UTF-8 without BOM, but I get the same problems. Thanks.

Wow thats service,Thank you!

I will update you when looked/replaced it.

Recently I bought a 3D printer. An Anycubic Kobra S1

 

It's been a bit of a learning curve but Anycubic support were great because they kept sending me parts for free (3 times) to replace the bits I broke from my own stupidity. I thought about making one with Linuxcnc and ethercat hardware because there are native interfaces for all of the required sensors.... Then I looked hard at the Vorons. But decided to go with buying one for a change. With the benefit of hindsight, the multi-material AMS was a waste of money for what I've been doing. I've only used it once just to say I could!

When I can print a M6 x 1 bolt that works, I think its fair to say it (and many other printers) are up with the Bambu's today but when things go wrong are probably not quite as easy to service (Flashforge AD5X excluded). But hey a hot end is only $10 and an extruder is $26 so just keep a few parts on hand (you might need to email support to buy them).
 

This is a concerted effort by governments including mine in Australia to control the narrative, limit freedom of speech and allow the government to label content as misinformation if it does not conform with their narrative. its not just the child safety here, its a lot deeper than that.

Yes, the regression analysis I did on 16000 readings showed the torch height to torch voltage was accurate to within 99.4% confidence as reported in the Plasma primer

HOME_OFFSET is used to manage squaring during homing. If there is 1.5mm difference per side, make the home offsets different by 1.5mm.
For initial squaring, I used a dial indicator and homed againt that. Probably a more accurate way is to home the machine and mark positions in each corner with a tool and adjust the home_offsets untill the measured diagonals are exactly identical.

Why are you using Python when the feed rate is available in real time in motion? There are other options but try this pinmotion.feed-upm OUT FLOATCurrent feed rate in G-code program units per minute for motion.motion-type feed(2) and arc(3). Value is the G-code program F value multiplied by the current feed override value and the motion.adaptive-feed setting (if M52 active). Value is zero if motion.feed-hold or motion.feed-inhibit are asserted. If units (G20 or G21) are not specified in the G-code file then units will be the last units used.linuxcnc.org/docs/stable/html/man/man9/motion.9.html

Hi!
I am 99% sure that I do have G54 in my startup code, but I will double check tomorrow.

Thx!

Update: Confirmed - G54 was in the startup code line.
