4.4k or 7k motors?

I can get 5 Nema 17 motor 4.4 kilograms at the same price as the same motors but 7 kilograms. I have two motherboards, one ramps 1.4 , and one mks sbase 1.3. (I have not yet decided which one to use).

Does it make sense to use the 7-kilogram motors or is 4.4k enough? The 7-kilogram motors consume 1.5 amps. I do not know if that consumption is too much for any of the two boards.

The working dimensions are 900X 600Y 120Z. All in polished stainless steel pipe with 1.5mm wall

I will use it for milling wood/aluminium and laser cutting/engraving.

thanks.

 

That is not a rating I am familiar with, larger is probably better here but if you gave model numbers maybe it could clear a few things up.

oz-in or N-cm are the most typical units I have seen.

4.4 (ncm ???):

Brand: Maker Parts

Code: MKP42HT47-1684A

length: 47mm

I don’t have any more specs

 


7 (70ncm):

Brand: Leadshine

Length: 57mm

bipolar 4 wires

resolution 1.8

1.5 amp

2.5 ohms

6.5 mHy

 

Yeah I can’t find anything, you might want to look for a brand that you can be sure what you are spending your money on. Way to many variables to go in blind.

Every spec sheet that pops up for that model has different info.

I understand you are talking about maker parts. I do not know anything about steppers. Leadshine is a more reliable brand than maker parts ?.

What country are you looking in, if you are not in the US maybe someone can vouch for a seller in your country.

Candy-ho tiene motores maker parts tambien.

 

Have a look at this, here you can see how the Amp rating doesn’t tell enough information. I suspect if the seller isn’t giving all the information it is probably not something you want to buy. Look for some others with more complete info.

 

Hopefully someone from Argentina can jump in here.

Hi

I am taking a guess based on the model no.

4.4 (ncm ???):

Brand: Maker Parts

Code: MKP42HT47-1684A

length: 47mm

I think this stepper motor is a 62oz·in, 4.5kg·cm stepper motor running at 1.68 Amps, but I cant be 100% sure.
