Generic Spindle interfaces, I/O boards, Misc boards and panels / Re: How to configure 422/407/Mach4

« on: April 28, 2018, 07:23:53 PM »

Forgot to mention... I have also followed these instructions

New steps:
* Go to the "Configure" menu and select "Mach".
* Click on the "Spindle" tab
* In the first row (labeled "0" - zero), fill in the minimum and maximum spindle speed.  Note that even though Mach4 supports 20 different spindle ranges, by default it uses range #0.  It requires custom-written Lua code and/or a custom screen set to select a different spindle range.
* Optionally, you may fill in the spindle accel and decel times.
* Leave the feedback ratio at 1, this is only used when there is a sensor on the spindle to determine actual spindle speed and the SmartBOB does not yet support this feature.
* Set the "Max Spindle Motor RPM" to the max RPM that you want your spindle motor to turn.  This should reflect any pulley ratios between your motor and the actual spindle quill.  So this is the motor RPM when your spindle is at the speed that you entered in the "MaxRPM" field.
* Leave the "Step/Dir Spindle Axis" set to "None"
* Leave the "Enable Step/Dir Spindle Rigid Tapping" un-checked.
* Click on OK

Generic Spindle interfaces, I/O boards, Misc boards and panels / How to configure 422/407/Mach4

Ho Folks,

I finally got around to plugging in my new 407 to my 422 (which has been running beautifully for several years). I have followed the wiring diagram for my Huanyang VFD as confirmed in another post here https://www.pmdx.com/PMDX-Forums/index.php?topic=348.0 and also set PD001 and PD002 to 1

But I am having an issue trying to configure the plugin.
I have updated all software. Mach 4 Hobby to build 3481 and SmartBob USB to Ver 0.52.254

But the "Start Here" instructions for the 407 are written for an older version of Mach4 and it has changed quite a bit.
No matter what I set things to I get an error (unless I disable the spindle config).

Are there any more up to date default setup instructions for Mach 4 anywhere? I've looked about but cannot see any.

All/any help greatly appreciated.

Neil.

Hi Bob,

I replaced the Machine.ini as you requested and ran the tests.
The mill ran faultlessly (except I had to throw all the limit switch inputs to Active Low)
All distances were correct using jog or MDI. Go To Zero actually went to zero.

Hmm... OK, went back to my original .ini file and redid all the tests. The mill is running beautifully.
Stuck a pen in it and drew a lovely roadrunner.

I swear I touched nothing in-between logging the issue and running these tests.
Actually, that's not true, I did replace a faulty spindle speed controller that the PMDX-422 is connected to via an SSR-25 DD relay on pin 14.
But I can't see how that would affect it.

Machine.ini attached (although disallowing the upload of file types ending in .ini is a little unfriendly)
