Yeap! After I tried to sanding it, I realized that it is not that easy depending on the piece.

I also found out that the Z axis was not perpendicular to the table. I will make a new try tomorrow...

Thank you for the reply. I got it that i need to lower the stepover but it seems that it will take forever to finish the job. Let me do some tests tomorrow.

Thanks for the reply. So you are saying I should go for sanding paper instead of wasting time with slower speed etc. ? So cannot be improved?

Here is new try with half 1200mm and the other half...

Good morning,

I did my first machine relief using Artcam.

My cnc is homemade so it is not that much rigid and cannot go over 1250mm/min (50ipm)

I first did a 6mm roughing pass then did 2 mm...

I have no idea what is an air cylinder. I have no issue with z axis / lifting as the stepper motors are very powerful. My concern is more about x axis as it runs on one rail (check the photo in the...

thank you very much for the replies.

I decided to go for the water cooled one.
But do you think my gantry will support 1.5 kw or 2.2 kw or should I go for 0.8kw ? My concern is the vibration or...

Thank you for the reply.

I would love to, as there is a very smaill difference in price. I can also have 1.5kw with er16 collet. The problem is, I do not know if the gantry will support it. Maybe...

no other opinions?

Thanks a lot for the reply... I am planning to go for the water cooled one, after I saw some videos about the noise difference...

It is leadscrew...

Any other opinions?

Good evening,

I recently bought a cnc (150 * 100 cm) without the electronics and thanks to the help of people in this forum, I went with this kit with a 48V power supply as it was avaliable in...

.Thanks a lot again. I decided to go for nema 23 to nema 34 mount adapter so that this problem will go away.
By your formula it seems that this kit is OK for me:

ACT Motor GmbH 3Axis Nema34...

exatly which steppers you are talking about?

oh now here we go! :)

I decided that I need to design a Nema 32 adapter to Nema 23 for X and Y axis so that this thing of being insufficient goes away...

So another newbie question is: Can I...

How about these? with dm542 and 48v psu?

Thanks a lot again,

I am just a little bit worried because perhaps your 6090 machine has a lighter gantry, smaller leadscrew (mine is 25mm), 100 x 150 cm and I am pretty sure mine is less...

so dm542 is OK.
psu of 48VDC is OK.

The thing that I can not understand is they wrote 9mH but under where there is the specs "image" it says 3.8.
or am I missing something?

here is 2.4 mh:...

Thank you for the reply.
Leadscrew of 25mm diameter / 3mm.
Don't know what other specs you need?

The leg of the gantry slides on 2 triangular profiles.

Thanks a lot for the reply.

Here are more likely options that I have:

Thanks a lot for the reply.
I was just wondering what inductance means as I was reading the threads... :)

I have no idea in reality about what speed that I need, but as I was going through some...

Good Evening,

I am totaly a newbie to CNC world.

I bought a CNC without its electronics. It is 5' x 3' (150cm x 100cm) and has steel gantry of 60lbs (27 kilo) which moves on ball bearings.
