Mach4 General Discussion / Re: Reading spindle true RPM
« on: January 28, 2023, 04:06:38 PM »
Hi,

Motion controller is Pokeys 57E on M16D. I didn't play with Pokeys settings for months.

Mach4 General Discussion / Reading spindle true RPM
« on: January 28, 2023, 12:55:09 PM »
Hi,
Please see the video first.

I have no idea what happened but this was working before. Now the spindle RPM jumps while running.

Machine is a mill. Spindle is a servo. I confirm the servo drive shows the RPM correctly.

But interestingly when I speed up the spindle the range of the jumping numbers narrows. I mean it gets more stable. But slower RPMs are messy.

What could cause this?

Thanks

Same problem exist with PoKeys 57 as well. Threading doesn't work when spindle is in step-dir mode. I had to switch to velocity mode.

PoKeys / Re: Pokeys 57e and Mach4 mill spindle encoder SRO question

Hi,

My problem solved as follows:

As I described everything was good. In diagnostics screen all inputs and outputs worked fine. The reason Mach4 didn't display the actual RPM was just a screen set misconfiguration. I clicked the "Edit Screen" menu item then selected the "Spindle RPM" text field. Then in the "DRO Code" property I just selected "Spindle True RPM" then save.

After that Mach4 started to display the true RPM that comes from the encoder.

Solved this by an accident took my 2 weeks. Dang!

Your 2 week accident saved me a ton of time.  I had already spent most of a day pulling my hair out over this.  Thanks for posting your solution.  Worked like a champ!

I'm happy to help.

Mach4 General Discussion / Re: New with probing. Getting an error

ahahah How stupid I am. I didn't notice the settings tab then. Now I filled the values and it solved the problem. Probing works now.

Mach4 General Discussion / New with probing. Getting an error
« on: June 18, 2022, 03:46:53 PM »
Hi,
I just installed a 3d probe. Works at 24v. In the Probe tab I click the Measure X (or Y or Z) buttons but I get this error:

Error: Invalid probing G code

I have this file by the way and I didn't touch it.
C:\Mach4Hobby\Modules\mcProbing.lua

This is my first time with probe so I know nothing about probing. Do I need to edit this file to use the probe in this window?

Note: I don't get any error in the "TouchOff UI" screen.

By the way I noticed something strange in the latest Mach4 Hobby. In the threading cycle, say I enter 0.5mm as thread depth then Mach4 posts the g-code with doubled depth value. I mean it puts -1mm where it should be -0.5mm. Here's the sample line I just generated:

N105 G76 X-1.0 Z-5.0 R0.0 P0.5 Q0.1 F0.75

You might ask the Control Mode in settings. It is "Lathe (Diameter)"

It wasn't like this in previous Mach4 versions.

It is not a big problem because I can enter 0.25mm if I want 0.5mm thread depth but it's weird.

Thanks Gabe.

Hi,
 
I think there is some kind of misunderstanding or I should have mention that I can do threading after I switched to analog mode.

Thanks.
