I posted this in the CNC router section about a week ago and no one had an answer. I should have posted here to begin with... The vid explains it, slow zone works on the Z axis perfect but the X and Y slow zones do not work at all. Anyone know what's causing this ? Thanks! YouTube- noslo6.mpgI don't know why the youtube player screen won't work here on the Zone tonight ??? Last edited by SScnc; 05-23-2010 at 06:18 PM. |

| SScnc, Are you sure the Soft Max is set correctly,they may be set to long. If it is wrong Mach3 never reaches the "Slow Zone" position. Jeff...

| Hi Jeff, Yes, I think they are correct. Both axis will move to the 43 and 33 positions and of course to zero. And they don't even slow down for zero positions. And the axis do slam to a full stop at those positions. Thanks, Steve |

| Steve, 50% is extremely high , especially since your machine has very high rapid acceleration. Jeff...

| Also try increasing the length of the slow zone, just to see if it helps.

| So I'm guessing it must have something to do with my steps per inch, my Z is 25000 spi, the Y is set at 20000 spi and the X is 518.6721992 spi. But I really have no idea how to make it work. Jeff, the 50% is of course for homing and the X (y and z too) home perfectly so I don't see that as a problem regarding the slow zone unless I'm missing something. Oh and just to clarify, in the video when the X suddenly stops at the soft limits, it's not hitting any physical stops, that's just the soft limits suddenly stopping it. Any ideas ? Thanks, Steve |

| Steve, The speed setting is a function of the slow zone, try reducing it to 5% on the X axis. Jeff...

| Steve, After you change the speed setting make sure you click the "Save Settings" button otherwise the change you made may not take effect. Jeff...

| Hi Jeff, I changed to 5% on the X in homing and limits and settings are saved. Still no slow zone on X. I also turned the feed rate on my pendant down to 15 IPM for the X and no slow zone at all. Just for the heck of it I made the slow zone at 1000000, no change. I know other guys have belt driven axis and I assume their slow zones work so I must have something wrong. Thanks for the help so far, Steve |
