I use a 2.2Kw water cooled Chinese spindle.
I actually used your list for parameters last time I set the parameters. :)

PD000=0 for Parameter unlock ( 1 ) for Parameter Lock
PD001=0 (1 For...

Hello, I have trouble with error EoAn in my Huanyang vfd. According to the error codes this should be due to Motor Overlad at normal operation speed.

It have started to happen quite often even...

I have been a bit absent from the forum lately. With the steppers you are correct, after a long discussion over at mycncuk I decided to use open loop 3Nm nema 23 motors with low inductance and 5mm...

I have started looking at stepper and servo motors for the machine. I have decided that I will be using closed loop motors. But i'm still not sure if I shall go for closed loop steppers or servos. I...

I have been cutting a lot of steel today. Luckely I had good help from a friend and the right cutting equipment. I redesigned the whole thing for a fixed gantry design yesterday, since the steel...

I'm currently considering making a stationary gantry design. Since the weight of the gantry pluss the z and y cart comes inn at 80kg (mostly in steel).
The cons will be;
-Longer machine
-Longer...

I have been away fore a while from the forum, exam reading. I still read for the exams but i'm going to try to make some progress on this project the next two weeks. I have spoke a bit with a steel...

That's a very good idea. It could potentially help with both assembly, disassembly and tramming.

Now the whole thing begins to come together again. I have done some more FEA on the whole frame. I will just add that they are approximations and gives a rough overview. Joints and mounting points...

Update: Pictures is not good for viewing a design so I have placed it on GrabCAD for everyone to view in 3D. https://grabcad.com/library/z-cart-cnc-1 it's currently only the Z and Y cart since i'm...

90% of reading about stuff in the CNC world is finding the right word and phrases. Found the right word now "tramming" found also a lot of good info when I had the right search word :)

Edit: I'm...

I expect it to be a bit off. I'm going to epoxy level the surface for the profile rails. And then mount one side of the rails and use it as a datum for mounting and drilling holes for the other side....

Thanks for the insight.

I'm looking for lightweight so it's easy to move, and manoeuvre without any safety hazards. It must also be possible to move it though several doors. Edit: How do you...

Little update on the Z and Y cart design, after a lot of iterations i'm now converging on a better solution for the design. However there are still changes to make and improve upon, and I hope on...

A usual estimation for steel milling is 75N then I just added 25N to be on the good side. I usually use 100N because it is fast to calculate stiffness in N/um. I am applying loads 40 mm from the...

Update on the design. I have finally managed to get sufficient stiffness in the Z cart. The solution was no surprise, maximizing second moment of area, and... steel. I also moved the Z blocks down as...

Good point. Steel on the gantry and Z-axis is less of a problem when it comes to movability so this is a possible option. I'm going to explore some options with steel on the Z-axis. Since it have...

A lot of good suggestions.



The reason I did not space them further was because the z-axis became quite tall. However it is potential stiffness to gain, so I guess ill check it out.

As I wrote in the original post. Weight is the main reason for aluminium.

The cost savings are relatively small compared to other components.

I am currently planning to build an aluminum-framed router that will eventually have capability to cut different ferrous alloys. In addition, I hope I can do some high-speed tool-paths in aluminum....

Noen som har erfaring med KJN aluminium profiles link ? De har gode priser og ser ut til at de sender til Norge.

Ser etter aluminiumsprofiler, ser derimot ut som om alle de norske leverandørene bare leverer til bedrifter. Vet noen om riktig sted å skaffe aluminiumsprofiler til en fornuftig pris? Kanskje...
