General Mach Discussion / LIMIT SWITCHES vs SPINDLE

« on: May 05, 2014, 12:30:09 AM »

Hi there, seems like it is a never ending story, you get one thing sorted out and another one appears:::: Al limit switches work just fine, watch dogs is disabled in config..general config, touch plates are working fine etc, BUT when the spindle is turned on a message appears  "limit switch is triggered" there is no indication of which switch in the diagnostic screen or anything that is triggered, when the spindle is turned off...reset is pressed all is O.K. again until the spindle is activated again, anyone wwith any ideas or clues please feel free to drop me a line.. starting to get a bit frustrated (heaps of projects on the drawing boards to try....IF ONLY!!!)

Regards

X++, Y++ and Z++ limit switches are at the opposite sides of their "--/Home" counterparts
I don't have "++" switches on my Chinese router, so I have Soft Limits active. Soft Limits are in Machine Coordinates.
Note that the axes in Home/SoftLimits settings are reversed, that means that during RefAllHome Z will travel in positive direction and X and Y axes will travel in negative direction, i.e. towards Home ("--") switches/sensors.

Thanks very much ZASto, that really helped to explain it

Ok thats good.

If you press tab to get jog control up, then press the up arrow on the keyboard, does the the gantry move away from zero/home position i.e does it move in a positive direction??

Yes Davek0974, all the jog keys work in the right direction, my settings in the ports and pins setting were a little bit out

Thanks Zasto, I have read the manual, watched the videos, and yet I have difficulty understanding how the whole process works. I have referenced all the axis as per instructions but it still won't cut in the right direction e.g I will jog it to where I want it to cut, zero the axis, instead of going in the x+ and y+ direction to cut it will actually move to the x- and y- an then start to cut. It is not the lack of reading the manual, but probably lack of understanding how it works.

You messed something with settings.

Here are settings for a router that I'm using.
Machine is homing to the lower/left, jogs in the right directions, executes G Code in right directions.
As you will notice, I'm using same switch for Home/-- limit and Soft Limits.

Thanks for the pics Zasto, I have some of the settings different, but after changing them to look very similar to yours, it worked, I still not sure if I understand the X++ and Y++ etc, what they actually do if the whole lot of them were enabled like mine were, I could not find it in the manual, where it says you either enable one or the other or both, e.g Y++, X++, Y-, and X-, I may have overlooked it or didn't understand the explanation, OR maybe ALZHEIMERS is starting to kick in!!

Cheers

The G-code is good, I have run the same code before I changed screen sets, and had no problems with it, it ran from where it was told to run from, and in the right direction too!

Hi Davek0974, Yes I have switches at bot ends of the x and y axis, it is actually homing in the right direction e.g bottom left hand corner, it is jogging in all the right directions, but when I move it for example: the work is located at Y=50, X=100, that is the position I want the program to start cutting at, when I hit the cycle run switch it will move in the X and Y negative position and then start to cut, I should have mentioned that I am running Mach3 2010 screen set.

Thanks for the info Tweekie, I have solved the problem by adjusting the position of the limit switches and it works fine, All I need now is a step by step instruction on how to set them all up for homing and limits etc.

Hi there, to-day I tried to set the limit switches on my 3 axis mill, they seem to work o.k. except when the switch is activated the machine stops and winds back,BUT it does not wind back far enough to de-activate the switches, is there a setting somewhere to have the software to take a few more steps to clear the switches?
