General Mach Discussion / Soft warning on z max
« on: December 02, 2017, 04:01:39 PM »
below are a few lines of code.  I get the message "soft warning on Z-max". 
G55 setting are: x-10.0000 y-10.0000 z0.0 a0.0   
In soft limit settings, z is set to 0.0000

where is my code wrong for getting this error?  I have no other
z settings in the code except for the g55
please help

My friend asked if Mach 3 could 1. Do Polar Coordinates?  And 2, could Mach 3 also cut a line that moves off center by an angular amount.  So if an right angle from the end that has the smallest angle cuts a slot that is the hypotenuse of that triangle... then can mach 3 if you state the number of degrees of the smallest angle, then will it compute the run of the hypotenuse slot, based on that degree?  I hope this is state clearly enough?

ps to Rich.  I turned off my soft limits and promptly crashed and snapped a mill end (1/8th ") because I don't understand the g-code and how mach 3 treats it near well enough yet...so I think I should stick with soft limits and hard switches for the time being while and I practice and learn...this is my responsibility completely, not blaming anyone...I just need brakes on my car for the time being.

When I went to the hotkeys setup. I clicked A++.  Why call it A++? instead of A+?  Then after selecting A++ I hit the left bracket key. ([).  Then for A-- I hit the right bracket key.  Then I tabbed and got the jog flyout.  If I selected the step jog and hit either of the bracket keys nothing happens!  If I choose the Cont. then the A-axis moves but it appear irrational... if I hit the opposite bracket key it does not return to zero and so forth... it just moves all over the place...so what gives? bob

Rich

In Mach 3  we can use the up-down-left-right buttons etc for xyz movements... but is there a button that will move A-axis??? bob

Points well taken... but I was rear ended as a young man while sitting stopped--at a stop light.  I was injured, the settlement paid for the down payment on my home... ********* does come on its own...   I would not recommend this for people in general... bob

 Rich... are your saying you have no limit switches on your machine for protection...how, how do you keep your machine safe? bob

Once I figure out how to set up the index and pulleys, then I will cover as you suggest .  thanks bob

Rich... in reading Mach Turn pg 4-8, it says..."The limit switches are connected to external logic."  In this case please explain "external logic."   bob

I ordered the index pulse card and optical switch.  I will go to the electronics store today for the resistor and hall effect sensors.

Can you give me a short drawing of how the cd and all of this would look in how its attached to the lathe??

I downloaded lesson 8.  Thank you.   bob
