Hi, I have engraved a 6ft.x2.75ft ACM sign with a fullty converted 20V battery M-4.1

WOW! 
These look stunning! Great work!
Could you explain how you converted it to battery ? Did you buy a battery router or is the battery powering both the router and the maslow ?
It uses a DeWalt DCW600 20V-XR Brushless Router. There are two 20V batteries, one for each the M-4.1 and the Router. I have designed a new M-4.1 controller mount that attechs to the DCW600 and two 20V battery docks. I wil soon make a 24V custom battery for the M-4.1 for it will run bit faster. Cut times will depend on battery size/capacity. not voltage.
Happy Cordless Cutting,

If you feel like sharing in the printed parts thread I for one would be interested, looks like neat work!
Are you going to build the battery from cells, or use a couple of 12V tool batteries in series?
Im thinking about designing 24V-(6)_21700-5.0Ah cell battery case tower into a NEW linear bar tower.

Cutting a crosshairs mirror mount to sit in the maslow hole to center on a mark. Trying to cut from an abundance design. Very small pieces.
10mm thick particle board from a cabinet.
One pass, maybe a bit too fast. The abundance gcode is ok, not good on the top corners that were meant to make straight cut shelves. Drilling operations are slow but seemed to work.
Here is the thing I was trying to ideally cut and here is what happened. I might try it with slower travel speeds. and multiple passes I wonder if that would correct the wobbles. I ran it three times each a little deeper because I had not set the z height correctly. It was impressively consistent. the close up of the circles and holes below show that maybe it was coming back a mm off but really hitting the same marks each time.
There is a little wobble but the circles are pretty good circles and with a little sanding they looked great and it did fit in the maslow hole. I ran the program 3 times because it wasn’t deep enough in the g code and the ring of 8 drill holes shows that the maslow kept hitting the mark the same each time. They also line up well as you rotate the pieces and peek in. When I compare the circles to machined circles they look within .5mm. I don’t think this is a particularly good idea really for a tool but it was fun to try to design and then cut something out of abundance. It is just too much looking down a small dark hole even with the mirror.

I have lots of projects partially completed, but one is finally off the list! 
A local strawberry farm had cut down an old family tree last year. I made a table for them out of one of their “cookies”. I mixed black glitter into epoxy and filled in the cuts

First try at a universal pen tool that can be swapped out for the router. This version works but I want to refine it. I designed and cut it using abundance. cutting things that need mm precision with the maslow kind of worked but it needed a lot of sanding. The design could be 3d printed as a bunch of rings or cut from wood as a bunch of rings, held together but all thread rods with some inner tube rubber circles with holes in the middle to hold the pen or tool.
I will update with refinements and trials but so far so good. I really like the springiness of the rubber at this scale. The plywood and all thread is super strong and stiff.
I didn’t figure out the length of my cutting bit correctly so the splintered edges at the bottom were the mm of wood that didn’t cut becasue of that. I was really impressed with the clean edges.
Circles were slightly ovals with 2.5mm difference in diameter across the center. This evens out to about .6 or .7 (ha) mm of error in each radius which made it workable.
On mine so far I want to add a solid layer of rubber in the stack so that the end of the pen can push against that. The snug fit with the pen as is though works well.
The bottom larger ring and the ring with the the bump out for the button pusher are unnecessary and I am taking them off as well as the tiny rubber retaining rings. I did like the size of the rubber template.
It was very satisfying to design something and cut from abundance. it worked ok.

Fun. Playing with this more next few weeks. Next I want to update with a central core maybe that can click in and out with different pens and drag knifes and engraving tips.

It is a really really excellent design!

Awesome! I see the motors can’t shift around; does this create any issues/limitations?
Took the robot to school today. Fold up frame and pen holder instead of the router. It went pretty well. I need to practice more. Also awkward between tending to the finiky machine and the kids at the same time. It stalled out before we could actually get it to draw a poster. It’s a forgiving class and they were interested in it in general so it was ok. If I had two days with them we could probably get it carving a class sign. It did draw nicely on the whiteboard but then the sled erased it.
Took two computers so I could have them draw in inkscape on one and then use that to make gcode in krabscam on the Web then transfer via usb to the computer that is talking to the Maslow in AP mode as it can’t talk through the school Internet. Fast fold up frame travelled well. One of the kids after a bit says my dad has a big CNC so that was a nice connection. Ideally could have them all drawing at once on a collaborative vector platform and then use that to cut a puzzle or something. Working up to that.
Kids enjoyed taking turns helping put it together

Looks clean.
Is this the newest design platform?
8 foot by 8 foot map of the school finished. Kindergarten and I are going to go exploring this week.
Satisfying that it worked.
Using a hollow tube with 5 layers of innertube in it with holes in their centers. Very easy to pop drawing tools in and out of it. Marker dragged a bit on the fabric and the fabric shifting a tiny bit. Still pretty happy. Biggest problem was the markers inconsistent rate of flow. These were dollar store permanent markers 8 for 1.25 so I was ok with them being used up I did switch markers half way and will have to go back over some of the faint lines. but If I was trying to draw something that I cared about more I think I would need to find a tool with a more reliable rate of flow. Bigger markers might work better. The regular sharpie size did seem like it would work well for laying out a pattern for cutting with another tool. They also probably would not run out as fast on wood or something less porous.
Successes:
Biggest square frame possible 4800 by 4800 cutting area about 10ft by 10ft This piece was 8 by 8.
Find anchors ran no problems. Didn’t check for accuracy or precision.
Lawn anchors with three stakes each. solid and no problems.
1 meter wire loops as extensions with carabiners for clips. No issues
Pen holder tube cut on the maslow. Worked fine. Only problem was dragging friction. probably could play with force to correct that.
Inkscape to trace map.
KrabzCAM to make the Gcode. Engraving Follwo path operation, 2500 speed. 10mm depth (but I started a bit high) I don’t know why some things wanted to cut twice? I don’t thing I had any double lines.
Things to fix for future:
Higher capacity and more consistent flow pen. (anyone have ideas? )
Could spray wasteboard with spray adhesive to keep fabric (thrift store sheet) in place
Check the weather. It is currently bucketing rain Just barely got it covered enough to finish. the blue light in the last picture is lightning.
Curious what other drawing tools would work well. Pencils might do ok with light pressure for a long run.

Were you using plunge or ramp in Krabzcam? Ramp starts high and lowers then comes back at the right depth.
Sorry got that back to front Ramp starts high lowers while moving, then goes back. Plunge goes straight down.

Good thinking. I should set it to plunge next time. Some large features were completely doubled so I don’t think a ramp down would be that long. I’ll investigate more.
Thanks! This is part of some ongoing product development we’ve been doing around the existing Maslow platform. We’ve been experimenting with different sled geometry, motion hardware and tooling configurations while keeping the Maslow control architecture at the foundation.
It’s still a development platform at this point, so I’ve been trying to share what we’re learning rather than get too far ahead of the testing. I’ll post more as the current configuration gets further along.

Looks nice and clean; can’t wait.
I am just starting in CAD and CNC, and I am not too sure about the different steps. It seems that some CAD programs cannot generate G-code for the Maslow system, and looking over the topics, there is a large number of G-code corrections that one must know how to run.
Can you point me in the proper direction to figure out the correct steps to follow?
Thanks
Ken
