Ok thanks. Can I connect both motors to one driver say the Y axis? would this solve my problem?

Hi Gerry,

          I am using a hobbycnc pro driver board. 4 axis. I will try that. Let me ask you something. I read on a forum that I have to have two limit switches on the slaved axis in my case it would be the y axis. After homeing Y then the Slaved axis touches off the limit switch and then mach can sync the two axis. does this sound right?

Sorry. Here is the correct one. Just remove the Dot txt and it should be ok.

General Mach Discussion / Xbox controller plugin

 Hello I am using a xbox360 wireless controller as a pendant. The plugin will not save the product ID or the vendor ID. Has any one else seen this?

 OK So I set the A axis home, limits the same as the y. I get now get raking when I jog. I can see the left side(Y) step before the right side(A). Do I need to adjust the A motor tuning so I don't get racking? I thought if the Y and A motor tuning numbers were the same then all should work.

 Hi ger21,

            Thanks for the reply. I did not set the softlimit for A. Thanks. I will do that.

General Mach Discussion / Gantry Racking

« on: March 15, 2015, 04:36:43 PM »

 Hello all,

           my y axis is driven by two motors. One on each side. I have Y slaved to A.  I notice that when I jog from my soft limit position the one side initially steps before the other. Then after the gantry is moving all seems ok. I don't have home/limit switches yet, do I need them so mach knows where the A axis is in relation to the Y axis?  Also I copied all the settings from the Y axis  and pasted them in the A axis in motor tuning. So I know the Y and the A axis are stepping the same. Any ideas? Thanks.

 Hi Big Bop,

  Its been awhile sense you posted, but I will try. Have you enabled the A axis port under ports and pins?

General Mach Discussion / Slight jerky movment

« on: February 21, 2015, 11:21:15 AM »

 Hello all,

              I have been running some test on my router and I notice some jerky movement. I ran a test file and instead of smooth circles It seems more hex shape. I have not cut actual parts so this is just a observation.  I am using machscreen 2010. I did not notice this before I installed the different screen set. Would changing my step resolution form 1/2 step to 1/4 step help? I may have to revert back to the original screen set and retest. I was just wanting some opinions Thanks.
