Supporting more router options will be the first thing that we do once things are moving smoothly on the first one
Looks the same as the Katsu and other Makita clones so the 2mm sleeve / downpipe trick should work fine

Will there be a new profile going on Ground control and Easel at all please. or will it run fine with the existing M2 profile thats on there?
Also, I’ve decided to put mounts in my concrete floor for the chains. how to the chains end? is it looped at the end? if so, what size is the loop so i can 3D print some parts ready for when it comes. im eager to get cutting 
It should run just fine with the existing profile 
The belt end has a loop at the end which is intended to attach to a 10mm bolt. Check out the page here for details: Building The Maslow 4 Frame — Maslow
You’re a gent, thank you. Finally whilst I remember.
On a previous update you showed ground control running and it displayed red areas where Maslow would find it difficult to cut. Is this completely eliminated cutting horizontal? so I can cut right to the end of my piece as long as I have something level around the boarder to support the slead as it moves.
Sorry to bother you 
I assure you that’s the final question. I only ask because I’m designing something now and wanna know if I can place my parts close to the edge to save material.
Even in the vertical orientation you should be able to cut right up to the edges of the sheet as long as you aren’t too close to the anchor points. Those red areas are around the anchor points to indicate that as you get closer to an anchor the cut quality will go down, but they won’t prevent you from cutting.
As long as you have enough distance from the anchor points to the edge of your sheet, you should be fine with cutting right up to the edge.

the old ground control/web controle/makermade software will not run the new
machine. It has it’s own web control like software running on the maslow itself
instead
If you are asking about CAM settings, those should be very similar (i.e. grbl)

Happy New Year @dlang, hope all is well with you and family.
Are you saying we can’t use Ground Control with M4?
You don’t need to use Ground Control. Maslow4 has a built in interface so you don’t need to install any software at all. You just connect to the machine directly over wifi and it will open your default web browser with a tab that looks like Ground Control.
No need to install any software at all on your computer and it works on phones, tablets…etc
To be clear this is your computer (or tablet, phone…etc) connecting to your machine. You don’t need an internet connection and there is no Maslow server that could go down some day.

correct, with the Maslow 4 you use a browser instead. The equivalent of
GroundControl is running on the board attached to the router.

That’s a great way to put it. Instead of installing Ground Control on your computer and running it there, Ground Control is running on the machine itself.

@bar Thanks for the update and fixing the link to the anchors! Brilliant way to catch the ball detent. It takes about 2.5 hours in petg with the filament change as I use pla for the interface layer to make support easy to remove. Do you think 25% infill and 6 wall/top/bottom is sufficient?

Woah! It’s so cool to see one out in the world! 
It looks great!
I think that should be great. The weakest part is the thin part of the wall, and I bet that with 6 walls that part ends up solid.
are the I2C lines exposed on any header?
looking at things like this to be able to add additional GPIOs in the future if needed
We don’t have I2C lines exposed, but we do have a serial connection exposed so adding GPIO shouldn’t be a problem at all. We could also add a display or really anything. There are two Aux plugs, one gives us two IOs for basic things like Z-axis probing or adding a laser, the other is a full serial port for adding unlimited IO or doing crazy things.

If it can switch a laser can it therefore switch a relay to power the router ??

Yes, absolutely. To do that you just need to change the settings. We’re not enabling it by default for liability reasons, but it’s a 30 second change if you want it.

Apologies if this has been answered elsewhere. I did search, but nothing came up…
Around accuracy, I believe I’ve seen 0.5mm and that there is areas that the machine will be more and less accurate. Is this 0.5mm an average accuracy across a 4x8 or a worst case accuracy?
Any sense on the precision of the machine?
How does accuracy look in the Z axis?
TIA!
Great questions.
0.5mm is a worst case number. The precision (repeatability) is quite a bit better than that…ie when you cut a shape in multiple passes it cuts the same path every time to a much higher precision than ±0.5mm.
The leadscrews themselves are very precise ie 3D printers use them and can do 0.1mm layer heights, but because the sled is sliding on the surface of the wood the warped-ness (Is that a word?) of the wood ends up impacting the precision of the z-axis much more than the accuracy of the mechanism. I’d say the depth on the z-axis is comparable to using a router by hand sliding on the surface of the wood.
