Hi there.
I'm struggling to find who supplied the following leaf spring connector - Would be great if someone knows the technical name for it

I have been searching...

I designed and built it, basically:

3/4 Aluminium structure.
Big! NEMA34 Servo Motors (from Automation Techonoliges USA) + Encoders
72VDC Power Supply

Hi, sorry for my late reply for some reason I have not received the alerts.
Yes, still available.

Hi guys,

Unfortunately I must sell my lovely DIY CNC as I am moving house soon and I will not have any space for a CNC machine in my garage for the next years :mad:

I assume the Forum does not...

[FIXED]
Dir low active and step low active on spindle's Port & Pins had the wrong value. I unticked both now the spindle is @max speed when Mach3 is @max speed. I hope my silly mistake help this...

Hi guys.
I noticed my Mach3 and spindle (1.5kW water Cooled) are not working as expected.

The issue is: when I set the spindle speed to the minimum on Mach3, the spindleis is actually spinning...

Hi guys.
I noticed my Mach3 and spindle (water Cooled) are not working as expected.

The issue is, when I set the speed to the minimum on Mach3, the spindle actually is spinning at 24000 rpm...

Thanks Dan, for your detailed reply.I'll carefully study your workflow.

One last question (sorry if I missed that), from my understanding I should see only plunges while milling these circles. Am...

Great.

The second part of the challenge is trying to find out what happened.
- Cutting tool not properly fixed - not an option as the job had successful dots after the bad ones.
- Missing steps?...

No idea.
The workflow using Artcam is pretty simple:
- I have imported the dxf file
- Clean/fixed the bad vectors using their cleaning tool
- Created the v-carve relief, letting Artcam to define...

Yes, I did close the vectors in Artcam before creating the .tap. Actually without this step I could no even generate the v-carve operation.

Maybe even closing the vectors the vector quality still...

I had to split my artwork in two as my old laptop was struggling. I have tried to mill just the first half. The first Gcode file had 32517 lines :)...

Attached, please check the .tap file and the...

Hi Dan911,

I used exactly this software to create the dxf file and this software is great. The dxf is perfect, the circles (or dots) have correct sizing both on my CAM software and...

Hi guys,
I have been experimenting a bit with halftone images (great challenge by the way). My friend asked me to make something nice with his favourite daughter's photo.

The issue is, my CAM...

Thanks ger21, it seems the corners are correct now - after setting the angle to 89. I have increased the acceleration as well, so far no errors (my machine has servo motors).

I've just done another test.
Using two different wizards, one for ciruclar pocket and one for rectangular.

The circular pocket looks good, no problems in any direction (x or Y).
But...

Hi guys,

I tried to cut a simple slot but something is not correct here.

The slot shown is after milling simulation, and it looks like a slot :o

Hi guys,

Is there any website that connects CNC router owners to similar concept as found at 3dhubs.com for 3D-Printing? (https://www.3dhubs.com/)

I found the concept behind the 3dhubs website...

Hi Peter.

First thing, I attacked the problem inserting the enable override jumper to "Lo". That killed the problem - So I could concentrate to track the noise at e-switch level.

As I had the...

Hi Peter,

The pin 10 is connected to the e-switch following the board instructions (image-01.jpg and image-02) - Schematic here

In Mach3, the pin 10 is setup as e-stop (image-03.jpg)

I am...

I think I've found something :)
Please watch the video:
Breakout board - possible noise - YouTube

A) The pin#10 led was flickering at the same pattern/frequency as the servo motor dither!...

Thanks Peter.
I will check everything.

Why the reset switch thing happens only when the bob is connected using a parallel cable? Because I have not changed anything from the ESS to parallel....

Hi Peter,

Finally I could test the whole thing using a different computer + ESS (did not solve the problem), so I removed the computer from my black list.
Then I connected the BOB using a...

Hi Nico,
What do want to talk about Mach3 setups? screens? I'm happy to support. Thanks.

Hi guys,
Glad to see the replies here, thanks!

I've got issues on my DC servo machine, I can't find the root cause why the motors bump in a random pattern...but this week I start to simplify me...

Hi Peter,
No sure if that could help, but I noticed when the bump happened, some LED"s blinked (~16 seconds is the first event) in the breakout board, please check the following video:
For this...

Hi Peter,
Yes, but I wrote a simple code using the "teaching" mode on Mach3 (similar code that can be found in Mach3 installation manual, page 5-25, to see how reproducible the positioning is)

Hi looking for some DIY'ers for sharing some knowledge at SurfCoast / Geelong area.
I'm still fighting against my bloody update using servos....
cheers. :wave:

Hi, after posting here I spent a lot of time trying to understand what's going on here.

1) I noticed the problem persists in all axis.
2) To isolate the problem I decided to turn off the driver...

Hi guys.

I tuned my servos using this great site (cnccookbook.com).
The motors now are quieter BUT something is happening and I don't know the root cause,

It can change directions with nice...
