Hi Tom

A strange problem.

I have finally got round to upgrading to version 4.29. It has all worked fine except the use of S for spindle speed control. I can no longer use the S command to change my spindle speed.

If I enter say DAC0=-500 into the kmotion console, my spindle will run at 24,100. This is correct.

However, if I enter either: -
S25000 in my gCode, or
(BUF, DAC0=-200)
This has no effect.

Oddly, If I change the max in the tool set-up screen from -2047 down to , say, -800; this does change the speed down.

My "S" settings in 4.28 which worked fine were

DAC0 scale -.02 offset 0 min 0 max -2047

By the way, is there a stable v4.30 yet?

Many thanks for your help

Edward

Hi Edward,

I think it should be min = -2047 and max = 0

Also DAC commands can't be buffered.  Use CMD instead.

(CMD,DAC0=-200)

No we still have not Released V.30.  But no problems have been reported with Test Version
