wouldn't you use a switch with an arm that was arranged so it could overtravel without damage? i have some microswitches that are pretty well made with rollers on the end of an arm. they do not have a

You would not care. Also, you need to make sure you dont overtravel into the switch. -- -hanermo (cnc designs)

if you hit a limit, isn't it pretty much time to reset? why would you care if you were off by a few mm, you probably screwed up if you hit the limit anyway? i am wondering about all this because i do

I think thats an excellent approach, imo. Kudos. -- -hanermo (cnc designs)

Yes, its a parameter. I referred to limit switches Re: speed and a 50 ms delay. Sorry I was not more clear. -- -hanermo (cnc designs)

Hi Brian, That is excellent! The only way I can test is with the ESS, but it seems that a solid plugin is not yet released. Waiting for your update... Thanks, Dan

Hendrick, I had some time between things so I added nudge buttons and put the code in the M macros. It works perfectly. All I have to do now is add the M1001 and M1002 calls to my G code. Thanks so

Well I solved my own problem. After some experimenting I realised something I probably already knew from my previous experiments with parallel kinematics and that is that the kinematics are only

Hi Dan, Wouldn't you know it should be done.. it is out for testing now! Will know more in 2 days... Thanks Brian

Hi Brian, Checking in again.... Dan

aren't you supposed to approach the home switches slowly when homing? i thought homing went close and then did a slow back and forth to set the home accurately?

Here is the video on the completed project. Thanks for the help. cnc x axis update http://youtu.be/P6J0Bo-9JQk http://youtu.be/P6J0Bo-9JQk cnc x axis update http://youtu.be/P6J0Bo-9JQk This feature is

i looked over your code more carefully and think i will give it a try. i like the idea of a nudge button and will make one for + and one for -. this will probably not be great for other users but it

Hi, I have a job to do some 3D machining in foam on my router, it's two-sided machining and unfortunately bigger than my machine. I can't face having to mess around indexing the part in x so I thought

For a small wood router, I dont think so. For home switches, or something truly accurate, or fast, yes. An example, for illustration: Running at 100 mm /sec, a 0.05 sec delay is 5 mm in movement. 6

thanks for the code. i might use it but a self centering fixture would be better. i bought some right/left threaded acme screws and nuts and can make such a fixture once i get back to my real shop

i agree that if mach3 does software debouncing that a hardware solution is not necessary. the circuit i mentioned has a period of 50 ms, i don't think that delay would cause a problem. i will probably

I would agree with Henrik, as usual. Further, a caution ! Gcode and machine movement can get very, very complex, from simple commands. This is because of LOT of stuff depends on you, and the machine,

Hi Spencer, I'm not sure what you're doing or trying to do is the best way to handle the situation and as you've been told you can't turn offsets on or off, the machine ALWAYS have to move in one

Correct. You can not delete it. Which was the point of my post. Gerry
