SmartBOB controllers and dedicated accessories / Mach4 Cant find PMDX smart-bob

« on: August 24, 2024, 02:47:54 PM »

I am getting a port scan did not find a valid PMDX Smart-bob USB Device after a reboot. The controller is a PMDX-424

I did NOT see the STS Micro driver in device manager and I did follow the instructions to uninstall and reinstall.
I now see the STS Micro driver installed and no yellow or red errors. I started up Mach4
and it still cannot find the PMDX smart bob. Second message ERROR I get "Could not connect to the smart-bob usb device.
Please plug in or check the usb cable and re-start Mach4."

I replaced the usb cable and noted the OS sound that it sees the usb device and device manager does posts shows the STS Micro populated.

Diagnostics screen shows the following:

Build: 4162
Screen Set: wx4.set
PMDX USB Device: Unknown PNDX device [UNKNOWN PCB] on N
PMDX SN: Unavailable no device found
PMDX ver: 0.53.263
PMDX Bootloader ver: Unavailable
PMDX firmware ver: Unavailable

PC OS is Windows 10 64bit

Mach4 ver: 4.2.0.4162

I ran the package current profile. If you need anything else please let me know.

Any help world be appreciated.

Thank you

SmartBOB controllers and dedicated accessories / Re: PMDX-424 and constant Motion Underrun Error

I just ran across this post. I am in the process of building a new cnc with the PMDX424 board and Mach4 software. My thought was the same as yours to run with a fanless pc. I had installed a ITX motherboard with a quad core integrated atom cpu. I have been battling this setup for weeks and getting underruns in Mach4. I was thinking this was a issue with the OS as I was running a Win10 OS and have installed the OS several times. I finally swapped out the pc to another pc that was a ITX motherboard with a AMD 6 core cpu and i am not seeing the underrun issues anymore. Hope this helps.

SmartBOB controllers and dedicated accessories / Issue getting spindle to run 424 and 407 connected to YL600

« on: March 03, 2019, 09:27:21 PM »

I have built other cnc system but new to Mach4 cnc.

I cannot get the spindle to run with the current configuration. Was checking if anyone has this VFD it is a Chinese YL600/YL620-A. I can get the spindle to turn when configured from the front panel but when configured with the PDMX-407 I can't get it to spin.

I have the wiring as:

PDMX-407      VFD
RUN     >     REV
COM     >     GND
AGND    >     XGND (digital ground)
AOUT    >     VI1
AREF    >     10V

(Picture 4.jpg has the pinouts on the VFD from the manual)

In the VFD I set P00.01 to 1 and set P07.08 to 3. These values look the same as other Chinese VFD's like this.

In Mach 4 in the plugin config under spindle I enabled PWM and the PMDX-407.

I tried running a s500 but I can't get the spindle to run. Am I missing something here? I have included info from the manual and other pictures of the 407 and the VFD.

Thank you for any help.
