Title: Help writing G-Code
Post by: smr14 on June 18, 2007, 01:53:03 PM

Hi,
I am currently testing servo amplifiers and servo motors using this mach 2 software. I need to have a program where I can run the motors one direction then back the other direction. This needs to be repeated around 100 times.  If it is two rotations then two rotations the other way and then this would be repeated 100 times would be awesome. I only test one motor a time on the x-axis. I realize this is very simplistic but I am having a lot of trouble sorting through all the G-code tutorials because I need to do something so simple but everything is made for the three axis. If anyone could help me write this that would be a huge help.....

to be honest it does not matter one bit, as of right now I have just been jogging the motor.

thanks for your help that works great.

Is there anyway to make the motor run at a higher rpm, or is there a safety setting in this mach 2 programming? If you could let me know how to vary the velocity of the motor that would help a lot.
thanks

never run Mach2 i've always run Mach3 maybe somebody else is familler with the motor tuning in Mach2

how do you change it in mach 3....i maybe able to figure it out and translate it to mach 2 from mach 3...

go to motor tuning and slide the velocity up.
Unless you just have your heart set on running mach2 you should upgrade to Mach3

well according to the sound logic breakout board I am using they say to use mach 2. I tried to use mach 3 and I couldn't get it to work but I didn't try too hard because the instructions said to use mach 2

I really couldn't tell you one way or the other. 
I would suggest click tutorials>Documetation above, then download using Mach2 and customizing mach2  somewhere in the pdf it should have the info on increasing stepper speed.

smr14,
   I have sent you a personal message. A G0 move is a rapid. A G1 is a feed. You can change the rate in the code listed below by placing a f********* in the line of code. This will not increase the rapid speed or override it. The fastest it will move is the amount you have set in motor tuning. I would go with Mach3 as well.
