General Mach Discussion / Re: x axis direction question mach3
« on: March 28, 2019, 02:58:45 PM »
ok I got it figured out was beating my head against the wall for nothing    as it turns out everything was right in mach 3     when a file is created in sheetcam and I locate my 0,0 corner in the lower right hand corner  the cut is in the negative not the positive

ok another thing about this machine   it only has one prox switch on the x axis and one for the y axis which is located at the front of the machine  the end closest to the operator after it does a ref all home it uses soft limits to know the extents of the machine   your suggestion puts the home x-0 and y-0 at the far end  the end furthest from the prox switches  it moves proper when moving down the machine it moves in a positive  ( away from the operator ) it is only depicted wrong on the screen for this particular application  I guess one answer could be to turn the operaters station around 180 degrees  then it would all be faced right  but that is not really practical either for this situation   all works    I would think there would be a simple setting in mach3 to reverse the motion on the screen only but I cant find that one

with this machine the operators station is in the front of the table  the table is 6 feet wide and 20 feet long ( the x axis )  well the x axis is parrelel to the wall and back of the operators station is against the same wall so when he is standing at the station facing the monitor the table is to his left if he looks over his left shoulder he is looking down the 20 foot length on this machine when he moves the x axis it is moving away from him  in the positive movement I would like the screen to accurtly depict what the movement is on the screen the table is moving   right to left   so the cross hairs should move right to left  is why I am wanting to do this

General Mach Discussion / x axis direction question mach3
« on: March 28, 2019, 11:23:01 AM »
is there a way to change the x axis direction on the screen in mach 3. currently on my screen when I move the x axis in the positive direction  the cursor moves from left to right   but I would like the cursor to move from right to left in the positive direction. I have played with reversing the motors and reversing in homing/limits  and the screen allways moves from left to right?

when I load a rotary job on mach3  the toolpath does not display properly when first loaded it shows as a round wheel when I home the machine and redraw the toolpath it will display the job correctly but allways puts the job at machine x-0 , y-0  not displayed at the work coordinates of the job and if I start the job I will get a soft limit warning if I ignore the warning and continue  the job will run fine   I suspect the problem has to do with the header of the g-code for a rotary job versus a flat job that is on the table top    but all the things I have tried has not worked so now I am here hoping some one will have the answer to my delima

General Mach Discussion / help with neuron thc and mach3
« on: December 15, 2016, 09:36:22 AM »
sorry if I am posting this in the wrong place  but here is my problem,   I am building a new plasma cutter I have mach 3 , with smooth stepper and neuron thc  I think I am real close to having it ready      I have the ohmic sensor  with a magnetic break away head ( no floating head )   when I try to do my cut I get this error


15.12_09:10:00->Error 1-> System can not set the initial height! Check the FloatHead switch and motor driver.

 can any one please advise on what setting I might have missed?

General Mach Discussion / Re: 4th axis setup in mach3
« on: February 05, 2015, 11:16:05 AM »
thanks everyone for their advice and explanation I have it working now and it looks great one more little issue that I found when I turn mock off and turned it back on it said that one of my motor speed is too fast for the kernel I have selected I am sure this is related to the a axis where I have the numberssteps per is 13. 84 velocity is 141780 acceleration is 21975I am sure the root of this is because I'm moving in degrees vs inches is there a way of correcting that to be a realistic number
