Drifting reference over time

Hi Shane

The attached 2-axis test program is one I use sometimes. You can edit the parameters at the start.
Run it and see if zero at the start = zero at the end.

If you need a single-axis version, let me know.

Cheers

Thanks Roger

I had to start a new thread as it looks like im getting loss steps occurring when running code only. Running a test in one axis only is enough to see the issue.
More information is posted in the Loss Steps thread. Hope to see you there if you can help further,

Cheers
Shane

The connectors on the leadshine drives are prone to failure, maybe something related to this?

If you are only losing steps when running code, try reducing the acceleration setting.

Hi Roger, Im trying to get someone on a series 3 to run the same test as this issue is not so visible if you are running only one off parts.
Im thinking you shouldn't have to reduce acceleration to fix an issue that wouldn't have been there a year ago when i got the mill. The other issue i have is ive never tested it when i got the mill to see if its a "now" problem or its always been there.

Its only on the X and Y with the Z not having any issue. Swapped the controllers around and X and Y are still misbehaving with Z being fine still so it rules out the controllers.

Dunno. Things can age - motors, electronics, and so on. Try it? No cost.
