Same drives but 400w. Checked before cabling the machine-green light. Fixed all cables, connect the drives- 2 faulty. Wasted a day at least checking cables and wondering. Was at the point of ripping...

on a very rigid router type machine even 0.8 kw will make 1.5mm deep slot pass without problem with 6mm bit 600-1000mm/m. obviously for dedicated aluminum machine 3kw will be best.
2.2kw can make...

usually fault of the crappy pot that regulates the spindle controll voltage

Agree with that. A must i say, for a better finish and faster speeds.

I remember this machine inspiring me for my first steel profile build. Great job!

From the looks of it it seems like made using Exact Stop mode instead of Constant Velocity, in Mach3.

What if you go to your CAM and before generating the tool paths, smooth them and convert the...

Whats wrong is your Z or your material hold. So if you are sure its not the Z , then its vibration of the thin material. How you hold it down?

Hi Andrew,

What would be that " more cheaper and more durable" ? I was contemplating using open plain supported bearings, but the bearing blocks are not cheaper than the roller supported square i...

Hi,
I am currently designing a very sturdy CNC with a moving gantry.
Basically it will be all steel soldered construction, meter by meter table size, RG 30 size Hiwin Roller bearing slides on X Y,...

i revised the plans and still checking on the prices of rails.

it is quite tempting to start building it right now, but..$$$. So i decided first to source and buy the rails. The drawing can be...

I wonder how this rails and type of slides cope with dust in real life. My small machine has V rails and in real life it is the main problem with it, though when i bought it, i read and was assured...

Hi, sorry, a lot of work these weeks.
Ok.

-Quite a challenge:violin:


- the thing is that they sell the tubes 6 meter long, that is why i calculated everything to be 6m long or multiplied....

Hi,
Time goes by and soon will need a bigger and stronger machine. Before half an year i spend quite time designing my next one. I called it Simple CNC as i like simple things. Now decided to follow...

mameman,

as they told you , download Easm viewer , download from CNCrouterparts the cad files, look for the biggest file which ends like .easm
Open the file and use the buttons to move the full...

Hi Crane,
why you go with this style of legs and not like normal table legs with a stretch bars between them? What was the saying: if it looks right will probably do the job and is good

Hi,
my small Romaxx HS1 machine has belt driven long axis/moves the gantry/ and axis length is 60cm , its driven at both sides. Each side has 2x24 + 1x14 teeth pulleys and is using 1/5" XL037...

Hi,
i have annoying problems with my long axis belt driven machine and have to upgrade it sooner than i thought. In fact i thought of building a better and bigger steel frame one using...

I thought of making a plane surface pouring self leveling epoxy for my build. It would serve me for many more things as i have nothing straight here and want to avoid o simplify this procedure. A...

many thanks! you are great! :D will take a look when i get home

Hi,
apart from CNC i have Photography as a hobby and especially time lapse.
I haven't milled PCB till now as all my time goes with another project. So basically what i need help with is sb to...

hi, i stumbled upon this thread while trying to make my c41 work. Now its working perfectly and in fact is quite linear. I hope you don't mind to use this thread to help others so here are my 2...

Man, it looks strong and beautiful! Cnc porn to our eyes:D
I like your idea with changing the plates, not spindle mounts. This machine definitely will cut like a butter anything with a powerful...

yes, you are right. English is not my mother language but from what i understand he doesn't need in fact 4rth axis. He needs machine to cut the rod to cylinders of exact lengths. he needs a machine...

have in mind that i am still trying to learn it and don't have 4 axis but in my opinion the most complete and at the same time having some sense to the beginner is RhinoCam. i believe also its the...

yes, the smaller one seems welded, and both had supported bearings. i asume he had not very good sales of the bigger one, though as i said i like it. i dont see a problem with the gantry bars, its...

and also the smaller one weights 34 kg plus 6kg electronics and can mill metal

the spiked feet can have plates to put on the table with a small cavity in the center

it took me an hour to find it again but look at that little chinese beast

dmorton,
why you insist in water filling the aluminum? it woulod not make the things better. What will make things better are 2 simple things:
1.asymmetric design, that means dont mirror everything...

Hi,
i have some project which consists of making stamps from wood about 50x50mm size. Sth like Celtic knots and other designs. i use 1/8 30 and 45 degree bits and respectively 5mm deep pass and...

this guy definitely did it. and the choices are not random, it seems like a well thought strategy to keep the integral strength of the structure. i wouldn't be surprised if he spend most of the time...
