I don't have any experience with engraving, I use the laser for cutting so just set the intensity like you would for the spindle speed for the whole job. Its one of those things that I know I could...

They are basic methods of either turning the laser on/off (TTL) and controlling the power of the laser (PMW)

Not what you want to hear - but almost certainly better to replace steppers with closed-loop.

You *could* attach rotary encoders onto each screw and - not sure of any COTS solution - knock up an...

Ok well, 15mm isn't a common pitch size but they do exist. However still, things don't add up.?

The drives are set for 2000 micro-steps and your direct drive to the motors. 2000/15=133.333333...

Ok well, straight away I can see something is odd because 125 Steps per setting doesn't add up.? The DM860A doesn't offer a micro-step setting that matches this setting when used with a 5mm pitch...

Anything bought online can be returned in 2 weeks. So be quick with a return claim. Cheers Andrew

Like I said I'm very sorry to have to say it and it's wrong that should need to. Also, I don't think he's not answering because of reading this thread, I've had others contact me privately and he...

Even 60Vdc isn't enough to reliably run 34's in my view.
I know I'm talking of a mill with gibs here and routers are looser running, but still., I could not get my 1080oz reliably above 450rpm...

Doesn`t sound good.

Did you buy it new ?
If so, surely you should be able to send it back or at least get it repaired under warranty or something.

Watching the video again I can hear as the machine stops a thud noise, can also hear it in the movement.! This sounds very much like one of the ball-screws is floating in the BK end bearing which...

Oh, here we go again, I'm truly sorry to have to say this but for that particular machine then yes it's about right.!! That doesn't mean it's correct, it's very wrong.

The problem and the noises...

No, it does not sound right. I'm leaning towards electrical problem rather than mechanical, especially running at a higher feed rate removes it. Check all the electrical connections are tight.

Couple questions to start.

Does it still do it with the spindle not running?

Is the machine maintaining the correct position?
I.e. if you start at X0Y0, run the program, then command a move...

No that would be Active Low.
Because the type is N/C Mach sees the signal all the time(High) and when signal disappears (low) the pin goes active. So it's (Active Low)
If it was N/O type it would...
