Power usage of just the 4.1

Greetings,

Dose anyone have a kw usage rating for a 4.1? Just the 4.1, as the specs for the power supply are not listed.

DeWalt around 20kw

Shopvac around 35kw

Thank you

The specs on the power supply are 120 watts, but during normal use the machine should be drawing about 1/2 of that.

Thank you.

2.8 kw (just used the 120 watts total for overhead)

So to run for 24hrs this setup will eat just about 60kw.

The problem im facing is I’m looking to do some fairly long carves (making solid core doors and then carving designs into them) and being off grid. We have a fairly good size battery but not big enough to give up 60kw, so I’m looking for a software solution for saving working states between day light hours. I think this might work because keeping the maslow powered 24/7 shouldn’t be a problem and just powering off the cut head and the dust support. Any thoughts?

so replace the power hungry router and shopvac with something more efficient,
see the route-b-gone through for a way to use a 500w spindle

(the router is probably not drawing it’s full rated load)

there is no problem with turning off the router and dust collection, and the
maslow will draw very little power when idle.

But you also do NOT want something like this to run unattended, if something
goes wrong and it stops with the bit in contact with the wood, it will start a
fire if left alone long enough.

Hey Dave,

Thanks for the reply. Your right about a lower wattage spindle but the trade off is slower cut speeds costing daylight time. I’m not sure if it would equal out in the end but I think it would be near the same work output given my stated purpose.

If I were planning that I would run it outdoors under a tarp and not use continuous dust collection but sweep by hand on and off.or vacuum occasionally. As dlang said it should not be left running alone anyway. Outside you don’t have to have dust collection or not constantly. I would also plan my cut in stages. One panel area at a time and with roughing passes to remove most of the material maybe as pocket cuts and then a separate g code to do finishing. That would also let you turn on the dust collection more when finishing.i would definitely plan firebreaks into my project where I could stop, check and assess. Also if it is going to be deep relief overall plan for how the sled will be supported and do some test sections. Remember that the sled needs islands or sections of the original plane to ride on every 6 to 8 inches. Plan for challenges and failures. I would definitely break it up into 5 hour chunks. Remember that you could go back in with a hand Dremel or something to take out islands or section breaks. If you wanted to upload a sketch of the plan we could look for break points.

that depends on if you need the power of the router over the spindle (there are
also BLDC spindles available which are more efficient). normally the maslow is
moving slowly enough that you need to turn the spindle speed down. it’s only if
you were using a large bit at a high travel rate that you would come close to
needing the full router power

I failed to take this into consideration. So this unit will most likely shift its focus to parametric designed furniture. There is a project someone here made that was a rhino desk that looked amazing. Something in that spirit. Maybe a more traditional lowrider v4 (I have a mpcnc with zero hours run time cough that I like the design of) when I have more space.
