General Mach Discussion / Re: Unwanted Step Pulses

Changing acceleration, velocity, depth of cut etc doesn't help. That's my experience here if it's motor related.

From my experience, if the Z is losing position, then reducing accel will definitely help.

However.

The fact that it appears to lose position, and then get back to position, really points to a mechanical issue to me.
If the Z were to lose steps, it's very unlikely that is will lose in one place, and then regain the exact same amount in another place. Typically, it'll do one of two things. Wither get deeper and deeper. Or slowly lift above the part and stop cutting.

What are the actual accel and velocity settings you're using?

You can also open .m1s files in any text editor. Notepad, Worpad, Word, ....

It sounds like you're getting resonance on your motors. Adding a damper can help to make it smoother.

the DRO's in Mach show the movement

For that to happen, that would mean the anomaly is in the g-code, and I doubt that is the case. If it were, you'd see it in the preview in Aspire. I've never heard of this occurring in either Aspire or Cut3D.

Also, that looks like much more than .035mm offset.

I believe you can use OEM for everything except setting UserLED's.

I use DRO's and LED's in the 1800 range.

You can use SetOEMDRO(1800) and GetOEMDRO(1800).

And you can use GetOEMLED(1800), but SetOEMLED(1800) won't work, so you have to use SetUserLED(1800).

As for saving them, I don't know when the change occurred, but earlier 3.0 versions won't save DRO's in the 1800 range, but 3.42 versions will.

The Wiki says the User range was 1000-1254. I believe it's now 1000-2000? I know it was specified at some point on the Yahoo Group years ago, but i don't recall the exact number.

What version of Mach3 are you using? Newer versions will remember all of them, while older versions will only remember up to the old limit. Maybe the old limit was 1250?

I've heard of couplers appearing tight, but are able to occasionally slip back and forth a little. Especially if they use setscrews.

Also, try going into the bios of the PC and disabling C1E and/or EIST if you have them.

Loose coupler on the Z screw.

Or, losing steps from too high accel. Lower accel by 50% and retest.

If it still does it, my vote is a mechanical issue.

The digitize LED on the settings page should light up.

With the 2010 Screenset, if you set up your jog increments on the Settings tab, you can cycle through them with the + and - keys while on the Jog Tab. You can use the "End" key to toggle between continuous ans step jog modes.
