General Mach Discussion / Re: A axis running slow under G1 code

« on: October 20, 2011, 03:57:18 PM »

About 10 years ago when I was just getting interested in the world of stepper motors I ran into Arts site on Mach and have followed it since. He has come a long way with Mach3. I tried a few other out there and Mach3 has to be the best of them all.

Hood,

Thanks!!!!!!!!!!! That got it going! I thought the diameter was for the drive pulley diameter....duh, my bad on this one. Now it shows the correct diameter on the screen. I set to use diameter for feed rate and bingo! it all works great. Once again , thanks!

I guess I still have a lot to learn about Mach3.

Hood,

Thanks for the reply. On the tool path page I have it set to X-Axis and A axis rotations enabled. I do not find radius on the settings screen. I am using Mach3 v 3.041. and I am also using cnc wrapper. It seems that i didn't have this problem with a little earlier version of mach3. Also when i load the wrapped file it shows the diameter to be very small and the X dimension to be long.

General Mach Discussion / A axis running slow under G1 code

Hello all, I am having a problem with A axis running very slow under G1 code. If i set the feed rate to 1000 it is about the same speed as 6 on the xy and z axis. I am running the Sieg mill from Littlemachimeshop.com with my own rotary design. G0 code works fine and the jog is fine. Any ideas?

Modbus / Re: ModIO config setup missing??

« on: October 03, 2009, 12:08:09 AM »

Hello every one,
I am new to modbus. I some what understand the concept. I have a M1 and M11 board from cnc4pc. I have been able to communicate with the board from the computer and also use the "test modbus" in the modbus configuration dialogue window. I have a PB switch in pin #0 and it gives me a decimal value like it should. I want that switch to say make the jog go in the x++ direction. But from that point I must have taken the wrong turn at the intersection because I am now totally lost at this point. Can any one give me some hints on the proper setup to have Mach3 vr3.042.029 communicate with the modbus board? I too have watched the videos and screens are different.
