Hello.
I’m TANAKA, living in Japan.
I chose Maslow 4.1 as my first CNC.
I bought a DWP611 router from Amazon and am waiting for the Maslow 4.1 full kit to arrive.
Now to the main topic.
・Initially, I designed and ordered a 4040 aluminum frame to match the metric wood frame on Maslow’s site, but I’m cancelling and switching to wood.
What kind of wood should I use? (Something sturdy)
・The voltage of the DEWALT DWP611 is 120V, but the voltage in Japan is 100V. Do I need to use a step-up transformer?
If so, do you need a step-up transformer that can match the router’s maximum power consumption?(Example: 3000w, etc.)
Also, if you don’t use a step-up transformer, the voltage of the power sent to the router is low, so do you need to slow down the CNC machining speed as the power decreases?
・What is the maximum power consumption of Maslow 4.1/4.0?
・Do I need to purchase an extension cable for the router and Maslow?
(Assumed frame 12×8)
Other questions will be added in the comments section when I have time.
I look forward to your responses.

I expect that it would be close enough, you probably do need to slow down a bit,
but you need to experiment with your bits and wood in any case.
・What is the maximum power consumption of Maslow 4.1/4.0?
the router will eat FAR more power than everything else, I don’t remember the
power supply rating, but I doubt it’s going to be noticable.
・Do I need to purchase an extension cable for the router and Maslow?

Some motors react poorly to being run at less than their designed input voltage. For example, they may heat up, lose power, etc. Given that the router in a Maslow is being run continuously, these sorts of issues might build up over time. So, you might want to contact DeWalt’s technical support department and ask for their advice.
If you really need 120 VAC, a high-current step-up transformer would work. However, this could be expensive, heavy, etc. Fortunately, there’s a (fairly) easy way to step up line voltage using a smaller transformer:
Find out the maximum current required by the router.
Get a transformer that can produce this current at ~20 VAC.
Wire one side of the secondary winding to the “hot” input lead.
Feed the 100 VAC line voltage into the primary winding.
Check the voltage across both windings.
Depending on which side of the secondary you used, you should measure either 80 or 120 VAC. If it’s 80, the secondary is “out of phase” with the primary, so the voltages are subtracting rather than adding. If so, swap the leads on the secondary and try again.
Once you have a working circuit, mark the leads in some manner and then figure out how to package things up. I’d probably find or build an enclosure that can hold everything (e.g., pilot light, power switch, transformer, wiring, US-style outlet).
Of course, the usual caveats apply regarding dealing with “house wiring” (e.g., good connections, grounding, insulation). If you aren’t comfortable with this sort of thing, back away slowly…
Thank you both for your answers.
Sorry, the reply was quite late.

I see, it’s pine.
My local hardware store doesn’t have 12 or 10 foot pine 2x4s,
but instead they have 3000mm SPF 2x4s,
but is this suitable for a Maslow frame?
(They also have confusing labels like 12F, 10F, 8F, etc.)
They also have 12 foot cedar 2x4s, but they are expensive…
I kind of understood the principle from the explanation, but it’s a little scary…The medium has a 3D printer, so it’s possible to create one, but it’s dangerous because there’s no place to plug in a ground wire that can be grounded or insulated.
I’ll make this a candidate as the final secret.

My local hardware store doesn’t have 12 or 10 foot pine 2x4s,
but instead they have 3000mm SPF 2x4s,
that is approximately the same as the 10’ 2x4, look to see if they have ~3600mm
versions (you may have to try a lumberyard)
but is this suitable for a Maslow frame?
yes, this sort of lumber will work. It looks like they do have longer stuff,
just in wider boards.
play around with the frame size calculators and you will see the effect of
different frame sizes on your avaiable cutting area. I’m probably going to build
a 10’ square frame today for a local makerspace because that’s a size they can
leave assembled. It will restrict them to about 4x6 clean cutting area, but it
will work
