Hi all, I have been working through some issues with my Cnc, have made some new discoveries and thought id see if anyone knows why I'm having this issue.

VIDEO OF PROBLEM - https://www.youtube.com/watch?v=38lDOMZstBk

I have ruled out the following...
Drivers
Cables
Connectors
Steppers
Binding
Computer (tried a different computer)
ethernet cord


Thanks

Hi,
I have a 2009 ez-router scorpion 4x8.
I have had a few of these machines and always had random issues I've had to solve apart from their tech support.

I'm having the following problems.
When jogging full speed 500in/min on Y and X and 187.5in/min on Z, I can get it to basically stall.
What I am trying to simulate is rapid moves when actually cutting materials, as it has had problem loosing steps.

So I took it a step further and disengaged the Z,X and Y steppers so they can run free to try and rule out mechanical.
I currently have my spindle off the machine and the spindle cable taken out of the cable tray as I am replacing it with a IGUS shielded soon.
So there shouldn't be any noise from the VFD as it is not run to anything.

I can still get random axis to stall when jogging them all around randomly. As far as I know the motor tuning should be from EZ-router themselves and the XML has likely not been changed...
I will attach some photos of the tuning, the xml file and a video showing the problem happen. Is testing the steppers this way not under load even a good idea? I know you can get false info when running them free of load?

Steppers are nema34 4.9a 1.8ยบ. I think ez-router rebrands them so info might not match up with anything online.
I believe drives are being powered by a Basler 40v 780va transformer

General Mach Discussion / "Reference All" Jitters in Motors (M3)
« on: January 09, 2020, 07:18:25 PM »
Hey all,
I have a EZ-router scorpion black 2011 4x8 cnc.
Have had it in storage for a while, just got it out and have been cleaning it up.

Whenever I reference all axis the Y-axis seems to have some major jitters, sometimes the x and z as well, but mostly the Y.
I attached a video showing the y axis with the gear not even attached to the table.

I am using the XML setup by ez-router when you purchase the machine.
After it reffs home and jitters its way there I can run Gcode and its perfect, no issues.

But when I "ref all" or even "go to home" it jitters it way there.
Any ideas? I will also attach my XML below

On mach3 R3.00

Thanks all.
