VB and the development of wizards / Re: SLOW JOG RATE OEMDRO ?

Unfortunately it does not work relyable, although I do not know if this has anything to do with bypass.
I tested it several times and it worked twice, but failed about 10 times (random).
The Jog rate indeed slows down, but for some reason the second time it has to touch the sensor the toolchange macro freezes and does not descend.
The problem is that the first touch move and the second touch move is copy paste and are completely identical.
I don't know if it has anything to do with two macros trying to access the same led, but at the point where the macro freezes it's not writing to the led.
I have to look further into this, but i'm running out of ideas

The FRO routine works, only not on fly now I'm using a pokey, i used a G100 before there the feedrate change was instantly, but i fried it.
The speed during programs can be changed normally with the F command, only a FRO setting change has a delay of about 2 sec.
For jogging i need to release the jog button first and then the new FRO percentage becomes active. On fly would be better, but during the toolchange i don't want to depend on me constantly holding the pendant anyway.
Your idea about bypassing the FRO loop or just the update line during the toolchange will probably solve my problem indeed.

Many thanks i.m going to try it.

Hello,

I have small problem that goes in the same direction as the above.

I use a touch sensor to compensate the tool length in macro.
The tool moves to the highest position above the sensor, moves down and touches the sensor.
Next it moves up and down again in small incremental steps to determine the exact length.
When I've changed the tool manually it repeats this and the length difference is corrected in the offset cords.

The first move down i did with incremental steps of 1mm checking the sensor between each step to prevent the tool from crashing into the sensor but this takes to long. Now i want to use a jog command which is terminated as soon as the sensor is touched.
I can however not slowdown the jog speed in the macro and it crashes into the sensor before it can stop.
Jog is related to the maximum speed. My FRO alters the normal speed and the jog percentage in the macropump.
Therefore i can not alter the jog percentage (OemDRO 3) in the toolchange because it's directly changed by the macropump again.
I tried changing OEMDRO 104 (the maximum feedrate), but this didn't change the jogspeed.

Is there a way to lower the jogspeed when i can not alter the  jog percentage?

thanks in advance
David
