Router project update – New stepper motor controller and spindle

It´s been awhile since my last post here but I have been busy last months on setting up my router, installing new spindle and another motor controller. I did fry my old stepper motor controllers due to the fact that I don´t  know to much about electricity. I did put a switch on the dc site of the power supply that caused my breakout board to fry with smoke and everything. I therefore purchased a Gecko G540 wich I must say I really like, very simple easy and reliable and it reduces all the wiring and therefore reduces the changes of messing something up

Gecko G540

This is my new controller, Gecko G540. Very easy to install and has a lot of in and out puts both to control the spindle speed wich I will do someday and also has inputs for limit switches and emergency switch. The micro stepping resolution is 10.

Now I am using a Ridgid spindle wich works very well. The speed range is 20.000 to 30.000 RPM but it would have been nice to have slover speeds also avilable. This works fine tough with all material that I have cut except plexi.

I have to shield the lower bearing from debris from the spindle, For now I am using duct tape as a permanent solution. I also did purchase more spindle bits from trend ranging from 1,5mm in diameter to 3,2mm bot spiral and straight cut.
It took me awhile to get the right travel on the x-axis due to the fact that the axis is belt driven and I had to find the right tension to get good results, now the accuracy is 0,1mm wich I am happy with for now. Later on I will redesign this axis and put on a lower gear ratio for more accurate resaults.

I have also added limit switches on all axes and they are also my home switches. Here you can see the limit switch installation on the Z-axis.

This is my limit/home switch on my Z-axis.

And below you can see my first piece that I made after improvements.

And finally a picture of me.

I am now making parts for my quadrocopter so stay tuned for more to come.

CNC Router project update – First part made

Hi I just wanted to let you know that my Router is up and running now. Ofcourse there is more to be done but I have already made few pieces with it, here is my most recent one. Vesen is the name I have given my router.

I was really proud that I manged to finish this piece before the new year since it was my aim to have the router up and running in the year 2011.

This is how my router looks now

I definetly have to make better/stiffer holder for my Dremel since this holder is far from being accurate.

Router project update – New parts milled and router ready for final assembly

New parts milled and reasy for assembly

New parts milled and reasy for assembly

Yai Finally my parts arrived, this was a long wait but they look gergous I must say:) Everything did fit do gether so now all parts have arrived so I can finish my assamble and start routing soon, hopefully.

 

Ballscrew inserted to nuts, this did not go as planned in the first try :)

Ballscrew inserted to nuts, this did not go as planned in the first try :)

When I first tried to insert the nut on to the ballscrew it went horrible wrong. All the balls fell out and they where so small. Fortunetly I had a bucket under to capture all the balls, I was worried this might happen. the reason for this mistake was that the tube that did hold the balls in place was not thin enough to go all the way to the to the threads. The tube that did hold all the balls in place was something under 12mm in inside diameter and therefore I could not take it all the way where the threads start since the diameter of the shaft was 12mm. The installation was easy, I just used some grease to hold the balls in place and made new tube to hold the balls with large enough diameter to fit over the shaft all the way to the thread. The second ballscrew went lot better.

Router project update – New parts for my router

Finally got some more parts for my router.

It looks realy good assembled.

The bolts for the linear bearings are M8 bolts but in the data sheets with the bearings it stated that this was M6 bolts. It looks like this will be ok but as you can see the clearence is very little between the frame and the bolt head.  I might have to change the socket head bolts to something else.

Those parts were made by Héðinn’s workshop. For more pictures click here.

New CAM software – BobCAD/CAM

Did purchase the Bobcad V24 pro and with it Bobart pro. This bundle cost a lot of money, but most CAM bundles do cost a lot. This software has many options and quite advanced toolpath compered to the low end softwares like Mesh-cam and Cut 3D.  Those where some of the software’s I did try out, I did try all CAM software’s I could find and BobCAD seemed to be the best buy for the money, given that it will do what is promised.

Above you can see a screenshot I made this weekend, making toolpaths for a part that is for my quadrocopter.
I think I have to live on a noodle soup  for the rest of the month, so lets hope the software is worth it.

Router project update – Stepper motors playing music, crucial step in my build

Now that my stepper motors are able to play all kinds of music they must be able to also cut something usefull, when my router is finally assembled.

I made a video of my steppers playing the tetris song. As you can see some of the motors are so deeply in the groove they had to be strapped down so they would not dance away.

Router project update – Frame done

I have now completely built a new frame for my router. The frame size is 1200x500x600 and I am hoping to be able to have usable area for cutting around 1000×400.

Now I am waiting, like a child on chrinstmas for my other parts to be watercutted.
