Help with "Step Timing Calculator"

Can anyone advise me on the following.

When I open the “Step Timing Calculator”, I can high light the numbers in the yellow fields but I can't get them to change. (I've never used a spread sheet before).

How do I get this program to cooperate?

Thanks

A picture is worth a thousand words

When the yellow cell is highlighted the value appears in the long edit box above the spread sheet.

Edit that and it will be reflected in the cell

Arceye,

Once again “illustration is the best instruction”.

I am able to get the field to “high light”, I can even select the number in the field and give it a black background, but the numbers will not change.
Is there some kind of permission I need to adjust in the spread sheet program?

Is there a better way to address "Tuning Steppers"? (I have stalling problems on Y & Z).

I see, the document is set to read only.
What is the best way to change this?

JT, save as did the trick, thanks.

All I need now is for Anaheim Automation to give me values.
They don't seem to be able to find ANY documents for the driver!
I haven't found much when searching via Google either.
Her is a long shot, dose anyone have paper work for a Anaheim Automation DPF 65003 by any chance?

Nearest I can find is that the DPF65003 was replaced with the DPF72003

This is the spec sheet for the 72003

The only tuning data is that the clock inputs are 15 microseconds minimum

I think I told you in your other thread that these old Anaheim drives should have the step timings set for 15,000 (or 15 microseconds). This might seem way slow when compared to the timings for some of the other drive setting examples used in Step-config. But you have to remember most if not all of those are micro-stepping drives and this is a half step drive (400 steps/rev). A step rate of 15 microseconds to this drive would actually be commanding your motors to turn at 10,000 RPM (if I did my math right). Some how I doubt you will ever need to go that fast (or that the motors could).

Hi Todd,

Yes, you did share timing with me. I think it was 10,000 if my memory is correct.
I believe that is what was used.

I have been reluctant to bother you folks here on the forum with the situation I'm dealing with.
I thought I should explore the instructions in the manual first.
This subject is surprisingly deep (so many things to consider), if I was going to need to have this knowledge on a daily basis I could see pursuing all of this, but as I only need it to get things going for now I submit it seems more prudent to just share my issue and revisit the details later.

When I run the “testngc” file under “Step Timing” in the “Stepper Diagnostics” chapter of the manual,
X axis has no problems, Y axis struggles (I’m losing steps), and Z axis just stalls and locks up.
This test seems pretty aggressive, G0 results in a rather high lineal feed rate. (Stupid high)! Can I change this?

When I run the “axisngc” program (dry, no material/cutting), it seems able, the Y axis growls however on arcs.
It's clear I have a configuration problem here.

If I am unable to get the values needed to calculate an accurate:
“BASE_PERIOD”
“MAX_VELOSITY”
“INPUT_SCALE”
What should I do?
The manual says “No Guessing”, I may not have a choice.
