I finally found is was a bad connection at the circular connector from the control cabinet to the control wire to the servo. Thank you everyone.

Mach4 General Discussion / Help Troubleshooting Z Axis issue w/ MB3 & ESS
« on: December 04, 2023, 04:08:19 PM »
Machine specifics.

ClearPath Servos X4: CPM-SDSK-3441P-ELS
Power Supplies X2 w/ two servos per PS: ClearPath  350/500 Watt DC Power Supply IPC-5
Controller: MB3 with ESS and Mach4
VFD: Fu Ling DZB300B002.2LSA Input 3PH 220V 50/60Hz Output 3PH 0-200V 0-60Hz 2.2KW 10.0A
Spindle: 3kw 220v 10A 400Hz
EMI Filter on power into control cabinet: CW4L2-20A-S 115/250v 60/50HZ
Large farad on power line to Spindle unknown specs it came with my original Chinese setup
Farads on all control lines leaving cabinet to servos.
Power and control wiring for the servos are all Teknic supplied wires EXCEPT I used shielded outdoor rated CAT6 wiring to go from the MB3 to the circular aviation connectors to connect to the panel (maybe a foot long with farads on them0.
Spindle wiring is grounded. It wasn’t originally but I opened it up and grounded it then to the machine. Each moving part of the machine is grounded to the next piece of the machine until it gets to the machine frame. Machine is grounded to the building ground rod about 3 feet from machine. The control cabinet is grounded to the wiring ground which eventually is grounded to the same outside rod.

Z Axis issues

I am having issues with my Z axis and can’t figure it out. I’m posting this in multiple forums since I don’t know which component is causing the problem.

Z will stop responding to Mach4 randomly. There are no errors and Mach4 thinks it is moving and shows the coordinates changing on the DRO even though it is stuck.

Restarting everything, Mach4, ESS with MB3, computer and the machine won’t usually get it working again. I have to unplug the power plug for the Z servo from the power supply side and plug it back in. Unplugging from the servo end doesn’t do it most of the time. There are no LED errors flashing on the power supply when this happens.

When the Z servo stops responding the green light is still flashing on the servo and the Z axis cannot be moved manually as the servo is engaged. As soon as power is removed from the servo, I can push the axis up and down no problem.

I know VFDs are horrible for noise and sometimes this would happen after running a cut but there have been more and more times when I haven’t even starting cutting anything so the VFD has not been running the spindle.
I have been trying to troubleshoot this and looking at the MB3 LEDs there are some strange things going on.

I have the HLFB+ outputs from the servos connected to the MB3 even though I have not set anything up in Mach4 to use them. I’m honestly a bit confused as to what all I can do with them but I connected them so they would be ready for the time I do figure them out. I’ve noticed the LEDs for their inputs sometimes are all lit, other times only some are and generally when the Z is not working only one of the Y axis servos (I have a dual gantry servo setup) will be lit.

Today as I was getting info together to write this, I noticed only three of the HLFB+ inputs were lit but all axes were responding properly. I have the outputs set to ASG-Position, w/Measured Torque in the ClearPath tuning software.

Before when the Z would stop responding this would be frustrating, but it wasn’t hurting anything because it only happened when not running the spindle but now it is.

I’m cutting a large sign from HDU (sign foam) I could tell static was building up on the dust collector line and then the Z started getting lower and lower and starting cutting completely through the bottom of the sign into my spoil board, but Mach4 DRO showed it cutting the correct depth. It was colder outside with lower humidity which added to it.

I stopped and grounded the dust collector line which seems to have helped a little but on my next clearing toolpath with a smaller bit I could tell the Z height was still off from where it should have been the further into the tool path it went.

Does anyone have any suggestions as to what I can do to troubleshoot and eliminate this issue?

I know this is a VERY old post but it is exactly what I was looking for. Is it still functioning correctly in the latest builds of Mach4? I've learned the hard way to triple check these kinds of things before blindly copying and pasting.

Greg, the Developer/Moderator at Warp9, said to post it over here lol I did post what I was running into there in case anyone else had the same issues.

I just looked at my old installation and there is no C:\Mach4Hobby4809\lua folder there either.

Interesting. I didn't notice the entire missing folder :)

Does probing work properly using the new ESS plugin and Mach4 4809?

I just updated to version 5125. I have an ESS and updated to the latest plugin for it. I renamed my old Mach4 installation and installed version 5125. Imported my backed up profile.

On the first start of my profile I get this error and Mach crashes

I uninstalled and reinstalled same thig.

Found the missing file in my old installation copied it over and things loaded.

In the old version every time I closed Mach4 it would crash and I would get the crash report that didn't help me. Same thing happens in 5125 but this time when I tried to start Mach4 and select my profile it would immediately crash. Mach4 will only start again if I select a stock profile to load, then close Mach4, restart it and select my profile but even that is a roll of the dice and sometimes rebooting the PC is the only way to get it to start.

I have changed back to a stock screenset hoping that would help but it doesn't.

Loading a stock profile has no issues with craching on close.

Any ideas? I really do not want to have to redo my entire profile and configuration.

Thank you for the reply. I've tried it with that enabled and disabled in ESS 285 prior to this but tried it again just now to make sure I wasn't missing something. I have not tried downgrading to ESS 277. I have Mach4 4809 since that's what was recommended on the Warp9 set up instructions

Mach4 General Discussion / Touch Off UI Find Center Not Working

Probing works fine for one Axis. I can zero my Z, find the edge of X & Y but if I try using the "Find Center" in my center finding touchplate it will move to the X-, contact the plate, then make a small move in the X+ direction and then disables Mach.

This is what History shows.

"X axis is performing a touch move.
ESS starting Probe 0
ESS: Successful Probe0 Strike.  Probing finished.
ERROR: No contact with probe"

I have an ESS and have "Probing Failure Disables Mach" deselected. I have also tried with it enabled with no change in result.

My grounding of the system is very good and have no noise issues.  I did try adding noise filtering in the ESS configs but there was not change. If it was noise I would also think I would have issues with other touch probe functions but all work for a single function.

I've looked at all the topics I can find and I may have missed the answer so if anyone can help I would greatly appreciate it.

Thanks Craig. I'll give that a try and see how it reacts.
