General Mach Discussion / Re: Mach3 + ESS wrong settings?! HELP
« on: July 11, 2023, 05:12:14 PM »
Can you jog any single axis and it works as it should even if you hold down the shift key (Rapid Jog)


Yes I can jog and rapid jog one axis at a time (500ipm on X and Y, 187ipm on Z) no problem.
I think I may have found the problem, my BOB was outputting weird voltages for Dir and pul. Around 3.5v and -1.0 depending on direction...

What control are you using, LPT, USB, Smoothstepper etc.

You have the A axis home and the probe on the same input.

If you are using LPT then with the settings you have set in the motor tuning you may be running out of steps at 25000Hz.



Sorry I didn't mention it has a ESS.
I will check on that input, I don't have a probe setup so not sure how that happened.

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

Another test I did was unplug power and output to both Y drives and ran the test in mach again full jog Y- and Z- and every time it still stalls the Z axis when moving the Y which isn't even plugged in via their drives.

6
Some new info, If I jog Y- full speed and try and hit Z- it will always stall. But not when I run Y+
When I run X+ and try and run Z- it will stall as well. But not the other way around...

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 1.8º. 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

open vbscript Editor, Mainmenue    Operator -> VB Script Editor

then copy/paste this code into the Editor

Code: [Select]
DoButton( 24 )
While IsMoving
Wend
code"(Z Axis is Referenced)"
code"G4 P.1"


DoButton( 22 )
While IsMoving
Wend
code"(X Axis is Referenced)"
code"G4 P.1"


RefCombination ( 10 )
While IsMoving
Wend
code"(Y Axis is Referenced)"
code"G4 P.1"

While IsMoving
Wend

If(GetOEMLED(23)=false) Then 'This will turn on the softlimits on
  DoOEMButton(119)
End If
While IsMoving
Wend

code"(All Axis are Referenced)"
While IsMoving
Wend

code"G4 P.1"
While IsMoving
Wend

Code"(Moving to Home Position)"
Code"G28"
While IsMoving
Wend

DoButton(7)
While IsMoving
Wend

Code"G4 P.1"
While IsMoving
Wend

Code"(X and Y axis are Homed and Zeroed)"

use the >|| button (Step Into Script) to run code line by line and see where the jitter happens.

BTW, do you have any values in

Config -> Homing/Limits -> Home Off. ?




OK will give it a go and report back and let you know about those values.

David,
I don't know your level of expertise with CNC routers, but the 'Go to Zero' button on the Mach 3 main screen is NOT used for sending your X, Y,  and Z axes to the "Home" position. That button sends your axes to any one of the six Work Offsets (G54 -G59) you set up and select on the Offset screen. Mach 3 defaults to the G54 offset. So what ever value you have in the G54 Work Offset screen is where Mach 3 will send the router when you hit the Go to Zero button. Remember, the G54 offset value is ALWAYS referenced (measured) from the Machine Zero (Home position).
The Go to Zero button will also send your router to any location you set up for "Part Zero"  (X=0, Y=0, Z=0) on your work piece (wood). Part Zero is usually located at the lower left-hand corner of your work piece. Once you move your three axes to that corner and "zero out" the X, Y, and Z DROs (Digital Read Out) in Mach 3, the Go to Home button will go to that position automatically every time you hit that button - as long as you start at the HOME position.
Ok, so don't use the Go to Zero button for Homing.
(Sorry for being so long winded)
Now, it's the G28 X0 Y0 Z0 G-code command that will send any CNC router to the Home position. Most G-code programs will have the G28 command at some point in the program to raise the Z-Axis first, then the X and Y axes.
You can see this in action by going to the MDI screen and typing the following:
(Make sure all fixtures and clamps are out of the way.)

G28 X0 Y0 Z0  (Rapid movement)
or
G28 Z0 (hit Enter)
G28 X0 (hit Enter)
G28 Y0 (hit Enter)
If you get a hand held "Pendant", you can set it up (OEM codes) so when you hit the Home button on the pendant it will automatically send your router to the Home position. The OEM codes also work in "Script" files.

Let's get back to your problem. Here are a few suggestions:
1. Go to the Config tab on the menu bar and select 'Homing/Limits' from the list. You should have all green check marks under the heading 'Auto Zero' column. Also, play with the Speed percent setting. It may be too slow/fast.
2. Go to the Config tab on the menu bar and select 'Safe Z setup'. You should have  a check mark next to 'Allow Safe Z moves'.
3.If you have the 'Soft Limits'  button turned on (green) on the main screen in Mach 3, go to the Config tab on the menu bar and select 'Homing/Limits' from the list. Make sure you are not out of bounds with your settings.
4. Go to the Config tab on the menu bar and select 'Motor Tuning'. Your Velocity and Acceleration may need to be adjusted (motors too slow or too fast). They may be struggling to keep up.

Hope something I suggested helps,
Roger



Thanks for your reply, I will give this all a try and report back

Yesterday I tried updating M3 to the latest and re-loading my xml for my machine. It solved all the ref all home issues, but now has an issue with the Z axis when slow jogging it will move much more rapid and sometimes continue to move when the “up down” keys are let released. It will sometimes stop mid move when jogging and you can hear the motor make a higher pitch noise, and then stop, lastly a watchdog warning will pop up in Mach when this happens.

So I reverted back to the r3.00 version, ez-router mentioned I should update my Mach to the update ending in .062 which I believe was what I was on. Should I update again and start trouble shooting from that version? It did solve the issues with the y axis which gives me hope...

Thanks for your time

David
