Nowadays I'm using firmwares made for the RepRap-controllers by simply using the extruder-STEP-signal for the laser pulse and the E-rate to define the pulse-per-mm ratio.
He's using Smoothie firmware, so there is no need to do any of that.
He just has to configure the laser module in his config, and he'll get full laser control, including pwm control via gcode, and laser/speed proport

there's no reason you'd need to do anything special, just configure the laser module as per the documentation, and use your machine normally, as either a laser cutter or a cnc mill (or both at the same time),
it's all supported

To steal is MKS way of doing business:
Eh, I didn't know about this instance, but MKS has a long history of conning people / stealing.
There's that guy whom when he asked for a replacement for a broken board, the person in the support line said they if they have to provide a replacement, their boss will fire them, so please don't ask for a replacement, they have a family to feed et

Once you understand something, it becomes a lot easier to use. Having MKS motherboard I happened upon that page where they essentially say if you have MKS board, go away.
That is *not* what that page says. The page says if you have an issue with a MKS board, please ask MKS for help first before you turn to the community of volunteers that board is destroying, it's only fair.

If you have a 3D printer or a laser cutter ( which lots of Smoothie users do ), it's possible you might be able to help the medical community.
Please take a quick read here:
If you are already helping, and are here because you need Smoothie help, please contact us as soon as possible to get priority assistance.

Hey there.
This is the Smoothie forum, not the Marlin forum.
You'll get better/faster answers if you post in the correct forum.
Dust has reported your message so the mods can move it themselves, but you can save them the effort by deleting this post and re-posting the same thing in the Marlin forum.

A few of the early boards had LPC1768 instead of LPC1769.
Most cloners use LPC1768 ( saves them a buck ).
You can ignore the message you'll be fine.

I believe a few people have tried that and some have seen improvements, others not. So probably worth trying, but YMMV.

...rd a go instead of the traditional smoothieboard for this replacement (sorry Arthur).
I will find you. I will kill you. It's just a matter of time.

You need to read the documentation ( endstops page ) about hard limits, and choose to either disable them, or configure them properly.
Also, if the motors "lock up", try moving more slowly ( F parameter in your Gcode, see documentation on Gcodes )
About the noises at intervals, where did you get your Smoothieboard and can you send a picture of it? Thanks.

Sorry for missing this post. Yes, Smoothie can do 100khz, and under some circumstances might work if you configure it at 120khz ( in particular you'd need to build a CNC version of the firmware with only 3 axes, see smoothieware.org/6axis ).
However, it's pretty much always easier to just set your micro stepping so the rate is at or bellow 100khz, and you're not going to see a difference in perfo

You want to read the documentation on configuration and firmware upgrades: upgrading the firmware ( especially for old versions, but really always ) means you need to update the firmware to latest version *and* the config to the very latest example config ( if you are updating from a recent firmware/config you can technically skip this by relying on the upgrade notes, but really it doesn't seem l

Hey.

MKS uses a 100Mhz chip instead of the 120Mhz chip that Smoothieware is written for ( and that is on the Smoothieboard ). This means as time goes by, it's going to be less and less likely for Smoothie firmware to run on MKS. We are already seeing more and more problems as time passes, and we expect as we implement the next set of major features, you won't be able to use t

I think the effect you are seeing is really the result of an extremely small height difference, and if you just increased your initial layer height by a very small value ( maybe 0.05mm or even less ) you wouldn't see it anymore and you could print just fine. Sometimes "a bit less than perfect" is good enough

Well, the algorithm is known to work perfectly on perfect surfaces.
It might be over-reacting to something barely detectable though, maybe due to some lack of luck with how the grid aligns with the physical thing ? Maybe .. it's all speculation really, I can't really think of anything obvious.

This could simply be something with how the probe measurements are done, interracting in a weird way with your machine geometry. Can you try changing ( increasing or reducing ) the grid resolution and seeing if it changes the effect ?

What's likely happeninig is your original file is too high resolution, so your host is trying to transmit more data ( more gcode lines per millemeter ) than the usb or serial line is capable of handling.
Because other boards are slower they eat gcode slower and this tends not to be a problem, smoothie tends to eat block faster, and the look-ahead ( which exist by default ) will cause those stops
