Suitable BOBs do make life far easier, especially with the micro sub-d connectors used.

ModBus is generally too slow for...

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 cramped nature of my workshop, I decided to assemble the machine in situ. After manhandling the lighter VMC 190 out the door, I brought in the main cabinet body and rear section and got...

With the rogue ball screws sorted and the wonky tooling tamed, I turned my attention to the control panel. The old one was a sorry sight—rusty and bearing scars from what looked like a minor...

The issue with microstepping, is that you're essentially relying on the energised coils to balance the rotor between steps, so any external forces can affect the actual position.
The reduced noise...

SOLD: Thanks for the interest generated. The two machines are sold.

This is a wonderful forum to be part of.

I don't know the Bambi, but the other link points to much larger and nosier ones. I mean, mine is only 6 litres and is basically the same, even the looks, as this one from HBM. Mine is really quiet,...

Yep, know the feeling. I think for Alu, Air plays almost more of a part than lube. Get them chips out ...

I think I'm going to try to return this VFD, I do think it's quite a good bit of kit, it's just the Chinglish that makes this a much harder job, I've spent the last 2 weeks trying to figure this out...

P1S with AMS (optional multi spool unit) plus one spool of filament was £909 delivered.
Less if you don’t get the AMS but if you buy it later it is considerably more expensive.

Bit of experimenting and it looks like the machine wants the z axis zero to be 20mm less than the machine max z axis…..

Found the perfect solution…… you have to admire my brilliance and stupidity...

Hello all:

Although my background has mostly been with CNC plasma, I am also interested in metal fabrication, and to some extent, machine work. In my younger days, I was quite active with car and...

Had a few emails asking how I'm going with this and the controller so thought I'd do a few videos to show the progress or more the point the tangent it's gone off at.?

Ah ah it's nice for a change for it not to be ME getting a slap on the wrist for my creative choice of words. . .:lock down fever I reckon ::hysterical::hysterical::hysterical:

I thought I'd post this I found on YT as I found it interesting to see how things where done. Good watch while stuck at home but Damn who ever picked those machine colours must have been colour...

Ok thought I'd make a short video because I've had lots of people ask me about these Servo's and when I've asked what controller they use most come back with one that is in 100Khz region which just...

Decided to re-vist my original plans for a belt tensioning system.
