General Mach Discussion / Re: Mach3 Turn FRP question

« on: October 28, 2017, 03:20:46 PM »

Hi again.

I've done too many things including fresh Mach3 install. Nothing changed. I've replaced the index sensor. Nothing changed. Index Debounce was 20. Tried 2 to 20, one by one. Nothing changed.

Hi RICH,

Thanks for your answer.

The "Index Debounce" is set to 20. I tried many numbers and found that 20 is best for me.

@RICH
Sorry for the delayed answer.

I tried Mach3's threading wizard to see if it would work. Please see the code below. It's for M10x1.5 10mm long thread. When I ran the code the same happened as my first post. Mach3 starts the spindle and axes goes to start point but waits there for something to start threading.

G0 G40 G18 G80 G50 G90
G00 G53 X10 Z10
T202M6
G00 X10.025
G00 Z0
G00 X10
M03 S300
G76 X8.2 Z-10 Q5 P1.5 J0.006 L45 H0.1 I29 C0.025 B0.0001 T0
M9
M5
M30

Anything unusual with the code?

I think the problem was mainly related to the index reading. It was something like 500 +-10 RPM and I think Mach3 wants a constant RPM to start threading. I widened the slot on the disk to 12mm. This improved the reading a bit. Now it's like 500 +-4 RPM but still isn't good. Then I measured the voltage of my C3 indexing board voltage. It was 3.5v. I then added a 5v power supply and dedicated it to the C3. While adjusting the output voltage of the power supply to 5.0v by rotating the trimpot, the rising/dropping voltage made the optical sensor fail. I ordered a new sensor. I believe the result with the new sensor will be even better.

My question is, does Mach3 wants a steady RPM reading to start threading?

By the way, spindle indexing sensor is working and;

- "Use Spindle Feedback in Sync Modes" option is selected.
- "Closed Loop Spindle Control" is unchecked
- "Spindle Speed Averaging" is checked

General Mach Discussion / Mach3 Turn FRP question

« on: October 17, 2017, 06:10:58 PM »

Hi,
I'm trying to setup the Mach3 turning post processor for SolidCAM that I found in the forum cnczone. It is the only PP I could find so I have no other alternative. Howeve, so far the post doesn't look bad except feed per revolution mode doesn't work. When I say FPR will 0.3mm per revolution it runs as CSS at 0.3mm per minute. I'm not an g-code expert (at all) but maybe you guys can help me.

Below is a sample gcode. Can you please help me find out how it should be for FPR run?

Thanks in advance.
Best

I've searched for days for a turn PP but couldn't find a proper one. Does anyone have any?

General Mach Discussion / Re: Can Mach3 recover RPM drops?

« on: May 10, 2016, 02:46:01 AM »

I thought so. The motor is an RC motor and the controller is an ESC.

Well, then I'll activate the governor mode on the ESC.

The BT30 spindle project located here:

General Mach Discussion / Can Mach3 recover RPM drops?

« on: May 09, 2016, 10:13:21 AM »

Say, I have a speed sensor and module that connects to the BOB and Mach3 runs the spindle regarding to the speed that is defined in the gcode. When the program is running and the spindle is dropping the RPM due to any reason. Can Mach3 recover the speed?

Sorry if this is a stupid question.

Yes, I know that controller. It's one nice thing. I don't know if they are going to release Mach4 driver tho.

Yes. That leafboy guy doesn't even have a public contact info. No way to ask him if he has a plan about the situation.

Too bad I have an AKZ250 on the way to me. I wanted to get a Mach4 license to use with it but I guess it's time to get an ESS.

The Chinese released an Ethernet BB for Mach3. It looks nices but no info on Mach4 support in the future too. The Chinese just want to sell without support.
