rather frustrated. If the need to pause and then stop the machine using the built in pause and stop commands in motion, there is no control over the path the machine takes to home. so if your clamps are in the way. bang bang.
So hitting the e stop to stop program results in the same behaviour. the machine upon re connecting will not perform any function except to go home. hey there that clamp again. bangbang.
What would it take to make the default " STOP" command in carbide motion just you know. stop. dont go home . just stop. then the user can jog as he needs to fix whatever problem he needsa to fix.
I guess its time to install the hdz and use a different interface
yes. and then you have three choices software wise
restart program. fine if its possible
press stop. machine immediately goes home. from whatever position its in.
turn off machine and reconnect. control is locked until homed.
You should be able to jog the machine while paused or stop should just end the the program and leave the spindle all the way up at last location. the software already knows where the spindle is in x-y-z. Why does it need to go home?
i should not have to take out work pieces or clamps or even the bit to facilitate a safe run home after pausing and wanting to end work in that program at that point. this is not even closely resembling what happens in a traditional CNC controller.
i know its a “hobby” machine and a self funded start up. but theres g code sent went the home button is pressed. we should be able to edit or stop that g code being sent
What I do is pause so the spindle raises, then power off the router and turn off the toggle switch (power down the circuit board). At that point you can freely move the router along the x and y axis so I slide it around any interfering objects and move it back to home myself.
You are right, you should not. What you should have done is plan for the worst case scenario. Design the work holding in such a way that it will not interfere with any moving part in any circumstances. There are endless low profile solutions you can apply to prevent such a crash.
I do not like the automatic movements either but I have learned to work my way around it and even to use it for my advantage. My X axes rail switches off my vacuum cleaner and the spindle when it returns to Y “0” at the end of a cycle. Switches on when starts the new cycle; quite handy when doing a batch work…
I appreciate your view but it doesn’t address the problem in the software. We can always adapt. we can always look back with 20/20 hindsight after a crash. But you cannot plan for every single eventuality. I am not v carving. I am profiling deep with a long cutter. My clamps are as low as can be ( 3/8" over top of workpiece total including bolt)
The software needs to stop when you hit STOP. It is ridiculous that it auto homes or that it’s not editable. Does it lose all position when STOP is pressed?
I can’t speak for other hobby CNC but no controller in the world has code like this. Nor does any machine ( unless a faulty component) move without command to do so.
Yes I’ve lost an endmill when I pressed stop. I also wondered why this movement to home was there. I would suggest that at the very least, the stop command should first lift the spindle to max height before it is homed.
going to switch as soon as i have time to install HDZ. I am expanding the machine to 49x49 over xmas so it is inecvitable anyway with the hard coded limits in CM
I’ve said this before. In my opinion machine motion should come from gcode that I run or from my direct interaction with the machine. I want crashes to be caused by me, not my control software. That said, I have a hard wired feed hold switch and a resume switch. Feed hold moves to a parking retract and resume picks back up where I left off. If I need to stop after a feed hold, I can do a soft reset.
Today I realised that it is truly impossible to plan for every occasion where an automatic movement can ruin your part, your machine, your end mill or all of those.
I was using a slot mill today and while I was using it I was wondering weather if I pause the job in CM would it pull the slot mill first out of the slot and then up or it would just simply pull it up.
I tested it in air just to make sure and it pulled straight up!
In this case the whole slot mill would be pulled into the flange above it!
I still think that the S3 is a great tool to work and learn with plus I guess that not a whole lot of people using slot mills but this can be dangerous. You are right, automatic movements should be an option…
