Door Open / Feed Hold Behavior

You think that because I was using Visual Studio, basic Notepad, and basic WordPad that it could have been my issue? I was trying to just start fresh on this Sparkfun red board (arduino uno clone) but I'm not familiar with how to wipe it clean and start over. I was able to connect to it in the OB control and flash over your firmware no problem. And as I said before if I upload an untouched grbl.h over to it in the Arduino IDE it uploads fine other than I think was an error message in regards to memory capacity I think it was. But as soon as I tried uncommenting line 564 by removing the // and saving it that's when it wouldn't work. I like that the folks at github suggested trying on an arduino first rather than me messing with the BB. Thinking about ordering a brand new fresh Arduino Nano that they suggested.

 

Appreciate it man. Really do.

 

So previously I used N.O. for my door switch (button). I have the NPN SN04-N switches installed. Homing is front left corner. Park Z at -10mm sounds good. Spindle is a 1.5kw so about 8-10lbs (it's ball screw driven so I don't think weight would be an issue). Machine is capable of speeds up to about 300 ipm (7620 mm/mm) from what I've found so far, but safe speed maybe half that. Spindle accel and decel I've adjusted to 1 second accel and about 2 second decel using a dynamic break resistor to help get a faster decel.

 

I won't be able to try much until I get home so no rush buddy. I really do appreciate this.

 

I can't wait to give it a shot. Yeah that pretty much what I assumed and how it worked for me in the past. Close the normally open contacts for (DOOR OPEN) , program pauses, spindle shuts down, Z axis raises. When I open the contacts that's when it'll allow me to even hit resume because it would shade it out and wouldn't even be selectable if the (DOOR OPEN) switch was still closed.

 

So all I should need to do is download that file and upload it as a custom firmware image?

 

Alright so I hooked the BB up to my machine and I've flashed over the hex file you provided. Everything works as far as (close the door contacts) job PAUSES and TOOL turns off and won't resume until I (open the door contacts) and physically press resume. The only thing it's NOT doing is raising and parking Z at -10mm from the original homed location if I'm wording that correctly. It actually doesn't raise Z at all. Just turns the spindle (tool) off and stays right where it's at. And when I hit resume it actually IMMEDIATELY continues the job to the point where the spindle even set at 1 second acceleration would probably cause an issue. But that's only because the Z axis hasn't raised up out of the way in order for the spindle to have time to ramp up.

 

Well, what I was doing was just a test wasteboard flattening that ya'll have built in to the control software. I set up a 100mm x 100mm area to flatten, zeroed my XYZ just above my table, and hit play. While it was doing it's thing I put a little jumper into the DOOR pin connector to simulate a DOOR OPEN situation. Job pauses, tool turned off, Z stayed exactly where it was.

 

Interesting. It's working now. Not sure what I did, but it's working properly now.

 

Hey @Peter Van Der Walt. So as far as this custom firmware you created for me which thank you again by the way. How often do ya'll have firmware updates and if I was to update would I lose any of the changes you made for me? I kinda would love to know how you made the changes and how you saved it out to a .hex file. Or maybe that's something way over my head.

 

PETER. Sorry to bother you man, but I finally got around to getting everything all hooked up and testing everything. Well, back when we last talked I had the BB temporarily hook up to test the door open / feed hold behavior where it stops the spindle (M5) and raises the Z to -10mm from machine coord Z0 (Z home - parking mode). For some reason now that I got everything hooked up it's not doing that. I initiates a feed hold, but just turns the spindle off and the Z axis doesn't raise up.

 

So after writing my last message I reset EVERYTHING, reflashed the firmware you made me and it's now working again. I don't understand it, but so far it's seems to be working now.

 

Hail
Trying to install this hex using the Firmware Flashing Tool, but console say 'Port disconnected'
When i reconnect, i still have unchanged firmware working.
My version of Openbuilds Control is 1.0.332
Something i missed ?

 

This is a very good news Peter !
I am making some videos on my channel @jjhontebeyrie and i will be able to present some more connexions with Blackbox.
And why not a 'Check Size' into the Menu button on Interface ?

 

Any delay Peter ?
