dspMC/IP Motion Controller / Analog Outputs not working

« on: December 07, 2020, 12:04:09 PM »

I have had to do an upgrade to my machine because of a failure in m motion controller card. I have installed a Vital System DSPMC/IP V3  controller, and have upgraded Mach 4 to the latest version 4.2.0.4300. I have installed the plugins for the controller into Mach. In the plugin configuration (Hicon 2.50.12), motors have been configured for control output type - Analog

• , (* is motor number).

Mach 4 is unable to control or command the drive movement with this configuration.

I am able to drive motors in both directions by issuing a voltage output command on the appropriate analog output channel, so I can confirm that the DSPMC board and analog channels as well as my drives are functioning. Just no control from Mach4.

I have another system that functions with analog drives but is with older version of Mach4 and DSPMC/IP V2.

Has analog functionality been removed or am I missing something?

Tks

Mach4 General Discussion / error 5: access is denied

« on: November 15, 2020, 10:59:44 PM »

Restructured our network and security. My cnc programs folder is stored on our server and is shared to everyone. The issue I am having now and need a work around is Mach4 errors every time I try to load a file. The operator is able to browse the files and even edit them but I have to run the program in administrator mode in order for Mach4 to load. Anyone have a work around as running as administrator is not possible for the operator.

Mach4 General Discussion / Router with Dual Motor on X Axis

« on: December 30, 2019, 09:48:40 PM »

I have a router that came with a cheap Chinese CNC controller. I have replaced it with Mach 4 and DSPMC controller. Router has Yaskawa drive SGDV-7R6A01A. One motor is setup as Master the other is slave. The issue that has come up Gin is that the slave does not always follow the master and a times will jump in mechanical position 3-10mm over time the bridge will twist out of square 3-4mm over the distance of the Y axis.
This is most evident when running a job using G54 and then at the end switching to G90 move, where you see one axis jump with the other motionless. I have successfully done electronic gearing of servos on other equipment but not on a CNC of this type.  Any suggestions would be helpful.

How can you switch between G CODE tab and MDI tab on screen with use of an input?

Thanks.

Mach4 General Discussion / Jerky motion

« on: April 21, 2019, 07:43:44 PM »

Setting up a manual knee mill with Allen Bradley servos, all are connected and functioning.
When I setup each axis using the DSPMC/ip axis setup/tuning screen, I get smooth motion, but when I try to jog or do a G00 x6 y6 move from with in Mach, my motion is jerky.

Motors will run at speed, pause, then run at speed, pause, run at speed….

This happens with either the X or Y axis (only 2 axis configured)

Motors MPL-A320P
Servo Amp Ultra 3000
Motion controller DSPMC/ip

Any ideas out there?
Thanks

Mach4 General Discussion / Modbus communications problew

« on: April 21, 2019, 07:33:57 PM »

Having an issue setting up modbus communications between Mach4 and PLC. I can write multiple holding registers from Mach to the PLC but cannot read any.
I have Mach4 installed on a computer and connected to a compactlogix PLC via Prosoft MVI69-MNET card via ethernet

PC IP address 192.168.1.40
Mach 4 modbus configured for TCP, IP address 192.168.1.48
1)   read register 50, 10 words long
2)   write register 1, 10 words long

MNET IP 192.168.1.48  - read/write to IP address 192.168.1.40
1)   writes to holding register 50, 10 words long
2)   Reads holding register 1, 10 words long
In my PLC data table I can see signals from Mach4 eg. Axis enable bits, but when I set a bit in the PLC that would jog an axis, the bit is not seen in Mach.
If I run a modbus simulator on the computer I see data from both in the correct registers.
As a side note, if I change the Mach modbus configuration to IP address of the computer with the modbus simulator running, I get 2 way communications.
What is wrong with me setup? I should not need to run a simulator.

Thanks

Mach4 General Discussion / Finish Z Move before X or Y

« on: March 02, 2018, 01:37:11 PM »

I am having an issue with my code. When I program a move on the Z to move the cutter into the work, before it reaches it's bottom position, the X or Y move begins.

Attached is the code

General Mach Discussion / Home Offset

« on: December 14, 2017, 10:41:27 PM »

Set up system today,

All Axis home to switch then to encoder marker. Z, X ,Y - All works as expected.

Then I programmed a Home Offset for the X Axis.

When run the Homing again, the X Axis move negative to the home switch backs off until the encoder marker, then lurches and trips on following error.

The same thing happens with Y and Z.

If I set the offsets to back to Zero all home and no errors.

dspMC/IP Motion Controller / Spindle analog signal

« on: December 12, 2017, 10:00:28 PM »

Having a mental lapse.

Hard drive crashed. Rebuild system but I cannot remember how I get the analog output to work for the spindle drive.

Spindle type - Analog (0-10v)
Spindle index - 7
Spindle scale - 100%

Using analog output 7 - Analog I/O port - J2 pin 19 and pin 17 (GND)

I get no voltage output from these pins.

What did I miss?

Thanks.
