I'd like to be more specific about T-Slot material and quality you say. But that reason why I post here to ask. Coz I don't know. I plan to work with aluminium/wood/acrylic. So spoil board is may not...

I will design CNC for wood/acrylic/aluminium and working area is 60cmx90cmx15cm. I plan to use T-slot for table top. I thinking about MDF, Plywood and T-slot. Then decision for T-slot due to it...

Never think about low inductance before. Thank for info. If have chance I will look into this when buy motor. So it hight torque at low speed. That why I've heard that it loose step when high speed....

Some comment please

For this machine I plan to use Nema23 Torque 3 N-m. good enough? Since this is not production use. More for research and hobby and I've read somewhere.



So for save budget, space, weight then I...

I see you use big screws 32mm! Because you want work with steel and stainless steel.
For me I plan to work for wood acrylic aluminium. I see some spec of screws from internet. Although I not know...

Thank for verify my read. So base on that. if I use:
16mm I can have maximum of about 2500rpm , 25m/min
10mm I can have maximum of about 1000rpm , 10m/min

Aside from my construction good or...

I capture to make sure I understand your. Start with 900mm free lenght then find the cut at 20mm diameter then down to fine permissible speed at fix-simple support. That is about 3000rpm. That...

Thank for reply seem it more detail in those catalog. Will try to study it. Initially I plan to use 20mm diameter.

Plan to build CNC working area is 60cm x 90cm. Z distance is 10cm.
For robot, uav, drone, rov, small wood work.
Work with wood, acrylic, aluminium.
Plan for 10mm pitch. BK,BF support.

What...

Those are good if I can't get bearing wider, the A u mean then. It seem easier to put it in front or top/bottom than in back I think. If put on top don't you think the top linear rail will get more...

I've done quick draft cnc plan but still long way to go. Plan to have working area 60x90x10 or smaller.
Still concern about:
- distance between block along x-axis rail (15cm),
- distance between...

Wow! Very nice info. Thank!

My design will be start 10mm pitch then. Since it my first and like you say. I'm not access to more accurate tools yet. Even need to buy drill-press. Or tap-hole. Etc....

Haha right!



I see, will add speed control to that.

I've some pencil drawing finish, will use computer to draw the plan then let you guys see/comment by next post.

Thank you.

Thank for remind me that. I never been cut thing with cnc before only hand saw for wood and plastic. What do you mean by "you need to at least consider higher lead leadscrews." can you tell more...

Noted. For rail rod will use 16mm, ball-screw is 20mm
Once have decision on these spec will start sketch, and design.

How about "supported-supported", "fixed-support" ? Actually I plan to use...

From your guys answers I tend to use 20mm diameter with 5mm pitch then. From I understand speed will lower than 10mm pitch by half but I will gain more resolution right?



I can see your pint...

Plan to build cnc for > 5mm-20mm plastic/acrylic, 5-20mm wood, maybe aluminum but not require.
Working surface is 60cm x 50cm , I've space limit.
I like design of ...

Wow dtac that help me narrow down the list thank!
Yes! I see the price of ViaCAD is interesting. So I even consider ViaCAD pro is affordable. But u really encourage to start from ViaCAD 3D version...

Thank for reply
I've already cut Bonzai from the list since it more on architect but I more on design a device , tools, equipment , model , more about mechanic. And I think I tend to like ViaCAD pro...

As newbie here. I consider to buy 1 or 2 CAD for use in CNC hobby. I look around internet for reasonable price and good feature coz I'm just want something good, easy to use and of course worth...
