Spindle pulley setup?

[dresda]

Bridgeport style mill with high/low with reverse back gear.
I set pulley#1 25-550rpm and ticked the reverse box,  set pulley #2 560-3800 If pulley#2 in selected in the config, spindle pulleys It says that way all the time as can be seen in settings screen.
When I change from high to low do I have to go into the config, spindle pulleys and change it to #1?
If I am in pulley #2 and in MDI I select s200m03 it doesn't change from #2 to #1 in settings screen, so if I change gear it still thinks it's #2 and goes backwards.

I should say I'm using a VFD and DSPMC.

Hi,
FYI - apparently the pulley reverse is broken in 3.43.22 (current lock down).
There was a bug in the spindle pulley reverse stuff that has been the subject of a thread on the Yahoo Mach list for the last couple of days. A new development version was just released today that is supposed to fix it (3.43.30).

If I tick the reverse in the box it does reverse, I just want to know if I have to go into the config, spindle pulleys screen every time to change it from #1 to #2?

You can change the currently selected pulley by changing the Spindle pulley DRO - in the stock 1024 screen set that DRO is on the diagnostics page. That avoids the need to go into the mach menus to change the selected pulley.

Hi Dave, You mean the settings screen right? That's OK, so Is that what i have to do when I change gear? I thought by setting the speed ranges it would then know what range..

You could alter your spindlespeed.m1s macro to look at your commanded speed and set the pulley DRO accordingly.

How does it normally work, I thought if you programmed your S command to the Pulley #setting it would it would change the # in the box in settings screen from 1 to 2, mine doesn't change.

OK, I guess I have to go into the setting screen to select pulley #1 or 2 every time I want to change gears, I just thought by selecting the speed range assigned to each pulley  it would shift from 1 to 2 even though I still have to manually change gears.

dresda, I had exact same question about gear change until I found your post.  My conclusion is, better not forget to change gears when running a program.  
I had another question, do you have a spindle index sensor on your mill?

I added a  spindle sensor to the top of my BP series 1 quick change tube and I think I'm realizing that I can't run it from there for the low gear because the index signal is actually read as 9 times faster than the actual spindle speed.
