F4.03 frequency should correspond to the F4.04 rpm. What you seem to have told the VFD is that at 50Hz output, the motor will be spinning at 9999rpm. That wouldn't work.

I note that F0.04 is the...

Thank you for your kind comments, I did do a bit more while I was distracted from my main project (Fairbanks Morse 15hp Model N )...

Hi everyone,

Some of you will have noticed regular periods where the forum has become completely inaccessible, throwing up database errors like "Unable to connect to database" and/or similar. I...

Cheers m_c,

Quick heads up then: If you’ve experienced any issues accessing the forum lately (especially database connection errors), I’ve posted a full explanation of what’s been going on and...

Due to the recent fleeting nature of the offical Cambam forum, Lee was kind enough to add a dedicated section here for Cambam users.

This thread had over 100k views, and considering that, amazingly few comments, so it is sort of a monologue, but because of the fairly high interest, I will continue.

4 Twist Umbilic Torus. What's cool is it only has one face.

First project with openSCAD programming to generate the shape, which also allows all...

OK, I finally found a well priced and well featured plasma cutter. Here we go again on another CNC project!

On this VFD you can't have both DC braking and braking resistor, as they are different mechanisms and you can only enable one or the other.

That "braking starting speed" threshold is only for DC...

Yeah, just a bit of a experiment really. £130 for a 10W 450nm Laser Tree 80 24V from their AliExpress store.

Made the first couple of cuts tonight - was a bit of a bitch to setup and I'm not...

Sorted out today with two bolts down the threaded holes :sneakiness:

The sensors I've got substantially cheaper from a friend who has no need for them anymore but are new, buying brand new each sensor itself is £140...

Thanks!

The X and Y axes have a thin layer of epoxy bedding that was cast against a flat surface (1" glass plate) to try and make them co-planar.

To put you out of your misery - the pillar...

After hand coding some gcode operations recently I wondered if it was possible to create a GUI and create them interactively. Since I have Excel on my machine and have written various bits of code...

Thanks again everyone for helping me make my build come true!
My first engraving is a message for all the people who think that the machine that they have started or thinking to build won't finish...

Steve P who has commented on one of my end grain inlay chopping board videos on Youtube was asking for some info on my settings. He's on this forum so I said I'd post my workflow on here as opposed...

Sorry Clive I misread your post (long day!) but actually it says the same thing!
1 point each !

Been trying a bit of stone with me chinky cnc

There have been lots of people looking for information on the popular (cheap!) XSY-AT1 VFD invertor, so I thought I would group as much information together as possible.

There generally isn't that much difference between an axis servo motor, and a spindle servo motor. The main difference is in how they're utilised.

A servo motor rated speed/torque is what it...

Both types of motor can be run above their rated speed however the difference is how long for.? An Axis servo can typically be run 100-200% above rated speed and torque but only for a few seconds. A...

The control box is installed and we get the motor parameters sorted and running. Plus some other jobs along the way.
