Mach4 General Discussion / Re: New limit/homing switch settings
« on: April 23, 2020, 10:34:55 PM »
Unless something has changed since I last talked to this user, the problem goes much deeper than that.

The Real Time I/O display panel in our SmartBOB plugin indicates that none of the limit/home signals are even getting to the PMDX-411, much less to Mach4's homing inputs. Communications between Mach4 and the PMDX-411 seem to be working because motion and E-Stop appear to be working.

User was asked to test inputs using just a simple jumper wire directly on the screw terminals of the Gecko G540. Test results of this have not been reported to us yet.

Mach4 General Discussion / Re: Mach 4 G-Code File Extension?

You can configure Mach4 to look for any file extension you desire, but the default install of Mach4 will show files with .nc and .tap extensions when using the File Open function.

Mach3 and Mach4 are fundamentally different in how they treat the relationship of Axes to Motors.

In Mach3 axes each have can have only one motor and when two motors are needed for one axis, you can slave one axis to another in software. This results in a "phantom" axis that are not actually commanded in G code.

In Mach4 motors are a separate concept from axes. The relationship between axes and motors is defined by Mapping. One axis can have multiple motors. Home and limit switches are associated to motors, not axes.

This can be a bit confusing, but is more flexible.

You stated that you have Motor 3 set up as a Slave to motor 1, but your config screen shows it as slaved to motor 0, which I assume is correct. You also have Homing configured for the A axis which has no motor assigned.

Do you have the input signal for Motor 3 Home configured?

The Ethernet SmoothStepper (ESS) works reliably and is well supported. Just sayin'     :)

It is probably time to ask Andy from Warp9 to connect into your Mach4 system using remote access and maybe he will spot what is wrong.

Dang it, I had assumed that DRO showed the requested feed rate, not the actual.  8-(

I must admit to not being very familiar with the details of setting up a SmoothStepper, especially with Mach4.

There was an option for "Controller Frequency" in the configuration menus for the Mach3 plugin and that could influence how the SmoothStepper generated pulses. It seems that is no longer present in the Mach4 plugin configuration, so it should not be an issue.

I am still curious if Mach4 thinks it is moving the motor faster than 500 mm/minute. In Mach3 there was an on screen DRO showing the current instantaneous velocity. Is there an equivalent in Mach4 that I am overlooking?

If the motors keep running at 500 mm/minute but do not stall, then I suspect a configuration error, possibly in your ESS setup.

While 3 mH is not great, neither is it that bad. With your setup I would expect 1000mm/minute or better, possibly even 2000 mm/minute.

When you state that 500 mm/minute is the best that you can get, do the motors stall or simply refuse to go any faster? If stalls are the issue, try running the motor with it not mounted to the machine and see if it will go faster unloaded.
