SmartBOB controllers and dedicated accessories / PMDX-416 Digitizing Probe

« on: March 14, 2018, 12:44:42 AM »

Hi Guys,

Is it possible to run a digitizing probe with the PMDX-416 and Mach4?
If so, looking recommendations on what probe would be suitable.

Or, is there another alternative??

THANKS

SmartBOB controllers and dedicated accessories / ERROR WITH NEW FIRMWARE UPDATE AUG 2017

« on: August 22, 2017, 11:19:47 PM »

Hi,

I have just reloaded MACH4 and loaded the latest PMDX firmware for my PMDX-416 as per email notification.

Now when I set my work zero position, move away and hit the Go to Work Zero Button in Mach4 I get the following message - "AXIS 3 COMMANDED WHILE DISABLED"

HELP REQUIRED.

THANKS - DARYL

SmartBOB controllers and dedicated accessories / Mach4 Touch Module Error

« on: February 20, 2017, 04:02:31 AM »

Slowly working through issues with my new build.

Latest Problem:-

Running PMDX-416/MACH4

When I try to do a simple Z axis touch off as soon as the tool makes the contact with the touch plate I get the following error -
"Can't transition from MDI to Stop"

I note another posting with this issue on this forum but there seemed to be no resolution.

Any ideas????

Cheers

SmartBOB controllers and dedicated accessories / PMDX-416 DROPS COMMS WITH MACH4

« on: February 18, 2017, 07:18:07 PM »

Hi,

Today I connected my 3 Axis CNC with all motors in situ on the machine.

I could jog X Y & Z OK.
Hi Guys,


When I send a test job with no spindle motor running, I get the following error in MACH4 after a minute or two of operation.

ERROR:  Could not disable the PMDX-SmartBob- USB error "cannot communicate with device"

Do you think I have an issue with - EARTHING - MACH4 - or PMDX-416??

Looking for a help to formulate a logical progression in fault finding this issue.

The machine is running 4 stepper motors (1 in slave)  connected to M542T drivers.

THANKS in anticipation.

General Discussion / PMDX-416 PIN ALLOCATIONS

« on: February 04, 2017, 05:05:42 PM »

Hi,

With my mechanical build nearly finished I'm looking at putting the control box together.  I have attached a PDF of the proposed wiring for my PMDX-416.  Would you be so kind as to take a look at the doc and alert me if there are any errors or omissions.  I am also incorporating two lead screws on one of my axis and I'm not sure if I need to look at extra switches to take care of any differences in stepper motor positioning for the master/slave combination. Any help or direction on this topic also greatly appreciated.

Many thanks.

Cheers - Daryl

General Discussion / Help Initial Setup

« on: January 18, 2017, 03:14:22 AM »

Hi,

I'm building a new CNC router and both PMDX-416 and Mach4 are new to me.  I have built an Arduino based CNC prior to this so have some knowledge.

Getting ready to set up the control box I have plugged the PMDX-416 in and it is seen OK by MACH4.  These evening I added a M542T stepper driver and motor as per installation instructions to bench test the set up.  When I run MACH4, I get an error that the PMDX-416 cannot be found during the USB scan.  Disconnecting the M542T has MACH4 "seeing" the PMDX-416.  Have I missed a step(s)?

THANKS

Daryl
