Yes, Mach starts the spindle.

Spindle is a fixed gearbox setting, 8 speeds, with one pulse per revolution. On the pulses per revolution, if I bring up the calibrate spindle page, it shows the pulses per revolution as 1, and it says "Zero if one per rev", and there is a box there with 1 in it. It won't let me change that to a zero for some reason. How do I change that to a zero as it should be?

I checked the backlash and the same setting still seem to be right. Just does some odd things when jogging, does not seem to do that when in a program. Another problem now, the spindle speeds are wrong, it shows 167 rpm when it is doing 500, I went in and got rid of any other ranges and set the min and max the spindle will do, no difference. I tried changing the spindle debounce all directions and no difference there either. Spindle speeds would be my main problem now, can't do any threading till I fix that, which was the original reason for upgrading to this version in the first place. Thanks for hanging in there with me Hood.

Have a debounce interval set at 300. Have odd backlash movement as well as the home off movement, as in the earlier post, it accelerates, then slows down, then accelerates again in a sort of two speed move. Once you get past that and stop jogging, and jog again in the same direction, it moves normally.

Yay, it works!! I originally had the step and direction pulse in motor tuning set at 2, I bumped those to 5 and off it went. A more noticable 'bonk' when you power up the Geckos as well. I seemed to remember that you should keep those settings low if you can so I tried them at 3 and it didn't work so I went to 4 on them all and it was happy there. Strange how that would be different for an upgrade, Mach must have different pulsing somehow. Also noticed that when I home the machine, when it comes to the limit switches, the home off movement is sort of different, it homes off, then slows down, them moves a bit more before stopping.

Is there an enable setting in Mach I may have missed? I am impressed how the new version of mach used my XML, and I didn't have to do anything at all, it was all there from the start. However, maybe switching from such an old version, 1.84, to a new one, 3.42, might have new settings in it that the XML doesn't have in it's old code. Anything I could look at there you might think of?

Well the mill is down now with an X axis excess lag error so it's time to try to get the lathe running again. I looked at the step and direction LEDs on the Sound Logic breakout board and they light up for direction one way and not for the other, all OK there, and the step lights are dimly lit as you try to jog so I believe there are actually steps being sent to the steppers. Remember, I hear a 'bonk' sound from the motors when I flick off the E stop and similar when I turn it back on, so I think there is something going there. Have to try to remember more about what goes on with the breakout board, I don't get 5VDC on the third connection for the Gecko output on the BOB, so I don't know there. Thing is, all I did was update the Mach software to a newer version, never touched anything electrically on the machine, and it was working Ok before that.

OK, after letting my lathe sit for a week and think about how it has wronged me and realise the error of it's ways I started it up again and it still doesen't get it. Actually I got my Lagun Allen bradley mill running and it's time to work on the lathe again. I rolled Windows XP back to an earlier time to just reload the old 1.84 version and guess what; it doesen't go either, same problem. Will try a couple of things now, need to open the drive up and see if the LEDs are lit for outputs etc.

No, I didn't WANT to change it to Mach, but bought the machine with no real knowlege of it's condition, so was trying to get an idea of some kind of backup plan in case the thing was dead when I got it. Actually runs well, but I have no manuals with it and don't know how to set a work coordinate or make the control accept one, it keeps going back to it's machine zero as a coordinate zero. Anyone have any idea?

Machine works fine, screen display is colour but just old looking. It is a 4 axis machine so I have a spare drive if needed.
