Yes, Terry. I am mapping the screw. It is a feed screw like those used in injection moulding extruders. The lead is not constant - can start from 50mm per turn and then gradually increase to 80mm per turn, then back to 70mm and 60mm. So calculating number of turns isn't going to help much.

Hi Terry,

Thanks for your reply. I did as you suggested - deleting MAch3 directory and starting from scratch. Didn't have a backup for the XML so took me a few minutes to take screen shots of all the settings and have them set back again. Now have the XML saved separately. Haven't yet tried to probe and see how this affected the buggy behaviour.

Now about the application. It is for probing a feed screw with an alternating lead. Y axis is the rotation axis. Z is the longitudinal axis. I have User DROs on the screen for setting feedrate, Zstart, Zend, Probing lengths limit, and probing resolution (how many probing points per single revolution of Y). I could have used pure Gcode with a sub and Vars, without using VB at all. However, I have to have a way to determine where to stop probing. I can't use a sub as I don't know the number of reps (the lead is not constant). This is why I am using While loop.

Oh.. and I am using an Ethernet SmoothStepper for the controller.

Do you think you have a better way of doing what I am trying to do?

Thanks,
Dan

Yep... he must know this better... will wait for him...

Hi Gerry,

I will be more specific. I have made sort of a wizard where I enter values in user DROs (like feed, Zstart, Zend) which which a VB macro then reads and does the probing. Don't have the macro on this computer, but it looks something like this:

Code:
M40
While GetDRO(2) > Zend
Code "G91 G31 Z-10 F" & "Feed"
Code "G00 Z1"
Code "G01 Y0.2"
Wend

M41
G90
msgBox "Probing Completed Successfully"

Think there is a problem using Gcode inside the macro like I do?

Thanks,
Dan

I have a simple probing routine. Something like this (but actually written in VB macro):

O0200
G91
G31 Z-10 F500
G01 Y0.2
M99

Repeated 200 times or so. However, every know and then a movement in X starts on its own (no where in the code is it commanded at all). Or the Y axis takes off at some crazy speed that the drive can't keep up. It will work fine 5-10 times, and then do that quirk.

Used version .062 and then reverted to .057 which seems to have less quirks, but still has them. It is in Mach3Turn if it makes a change.

Thanks,
Dan

Thank you Greg! The SS and ESS were great with Mach3. Just can't wait to see how the ESS does with Mach4!

Cool. Didn't know there were such ready things..

Very nice! How did you get the RH and LH ball screws coupled? Soldered? It's so neat that I can't tell...

Replaced the USB SS with an Ethernet one today. The machine worked all day and I didn't notice any random movements of the steppers. The monitor problem still exists. Now that there is a load attached to the AC motor, the monitor turns ON and OFF every once in a while on its own while the motor is running.

It is a Delta VFD. High voltage cable are routed separately from the low voltage wires in the cabinet.
