What happened?

the spindle seems to be under powered doesn’t go full speed. When I take a multimeter to the V1-10 output and ground it only shows 1v .. and i’ve used a small screwdriver on the adjustment and it doesn’t seem to do anything.. no change at all .. when i shut down the spindle it does go to zero though.

I’ve tested M3S18000, M3S24000 and it has no difference

Separate q:
I also had to reverse the movement on the X to get it to go the right direction.. hoping that is ok.

The video of the spindle is at: https://www.dropbox.com/scl/fi/e0vealv1pyt2pi5ujf4nv/IMG_4729.MOV?rlkey=vnz71qerl6j4u0e1fmjyzveeb&dl=0

I have a couple laying around and both do the similar thing.. the settings in the VFD are the same as what it was before.. i haven’t altered them at all.

You will probably notice that I didn’t deviate much from the sample config file for the 6x when I setup the machine.. other than some of the motor settings that the xcp had listed in their grbl config.

would love to finally get this machine going again.. it’s so nice, but their custom board kept having a motor driver dying and they quit supporting it for me.. so i am looking to get completely off of inventables hardware.

When you send M3S12000 do the io.13 and the io.15 LEDs glow?
Is 13 dimmer?
Send S24000 does io.13 get brighter?

What voltage is present on the 10v output terminal at 24000 when the VFD is not connected?

Are you sure the pot is turning? It typically only turns with a small slotted screw driver. Watch carefully to see it turn. Be careful not to over-rotate the pot.

#2 – kuito 于 2025-01-27

Hard to tell if there is a discernible difference in the brightness of the LED.

When I connect the wire that was in the AI1 to the multimeter and ground it.. when I activate M3S12000 it goes to like 1.7v then stays at .7v
M3S24000 it jumps to like 3-4v then goes to sub 1v too.

I do see the pot turning but I do have a feeling I may have over twisted the pot and it is freely spinning — it is hard to see moving, but I can see it moving.

If I love the pot when m3s24000 is running should the voltage change? If so, it is not.

I apologize for my ignorance with these things but will donate when I get home (didn’t bring wallet to my shop somehow)..

I really appreciate your help //g

#3 – MitchBradley 于 2025-01-27

Is your voltmeter in AC mode?

#4 – kuito 于 2025-01-28

Yes it was .. 🤦‍♂️
Okie.. so I was able to get m3s24000 to register 9.9/10v and m3s12000 to register 5.0v
And there is now a difference in the LED.

Of course, I re-connect my VFD and spindle and it isn’t firing up. The battle continues.

#5 – MitchBradley 于 2025-01-28

double check your vfd settings. I have seen them reset to defaults for obscure reasons.

#6 – kuito 于 2025-01-28

https://www.dropbox.com/scl/fi/9hszjgmeoq4p7iq8etfld/IMG_4753.MOV?rlkey=bhzp3nc54a1qix3r7elef8wwx&st=3l2iclbh&dl=0

This is the spindle and VFD while I go from 18000 to 24000 — does the rVAL (output freq) look right for those two spindle speeds?

F001=1
F002=1
F003=400.0
F004=400.0
F005=400.0
F006=1.0
F007=.00.5
F008=220.0
F009=12.6
F010=3.0
F011=0.0
F012=1

This is what I’m getting from the first 12 settings on the H100.

#7 – kuito 于 2025-01-28

If the spindle plate shows 110V .. does the VFD F008 need to be set to 110? (Asking before I break something)

#8 – MitchBradley 于 2025-01-28

According to this page https://www.aliexpress.us/item/3256807279354478.html , A12 is the 0-10V input.

!Image

A11 seems to be an output, according to the arrow directions. The representation of a potentiometer is goofy and the output arrow could be confused with a pot wiper, but I think the arrows represent signal direction.

#9 – MitchBradley 于 2025-01-28

There is also this oh-so-helpful text

!Image

#10 – MitchBradley 于 2025-01-28

I think this might be the manual https://workerbeeit.com/H100SeriesManual.pdf

#11 – MitchBradley 于 2025-01-28

The manual says this

!Image

Maybe A11 really is the right input to use.

#12 – kuito 于 2025-01-28

It was the input that the old inventables card used as the input .. AI1 and the manual I was looking at is similar to the last one you posted.

#13 – MitchBradley 于 2025-01-28

I cannot tell from your photos where the two black wires go.

!Image

One of them goes to the VFD GND next to A11, but which one, and where does the other go? I think it should be hooked up like this.

!Image

The 6x out-common pin is not internally connected to the Gnd for the 0-10V output

!Image

It is okay to connect out-common and Gnd, but unless you do so, or otherwise connect the 6x Gnd to the VFD GND, the VFD will not have a ground reference for the 0-10V output.

#14 – kuito 于 2025-01-28

I believe VFD GND goes to 6x GND. 6x Out common goes to a splitter that grounds with the power supply.. if I remember correctly.

Tomorrow, I can run the out common wire from 6x to the terminal you marked on the VFD. I haven’t tried that yet.

Thanks for your help with this.. I will report back tomorrow.

#15 – kuito 于 2025-01-29

I followed your instructions of putting the 6x common out to the top VFD GND terminal and then the 6x GND to the bottom VFD GND and I left the 1-10V out to the AI1. And I got:

I’m pretty stoked now and thank you so much.

Thanks again for all your help. I am very appreciative of //g
