Hmmmm Unfortionatly I have to low gear ratio on my X axis (far less then I wanted) due to the restricted area under the bed. I would have liked to make this higer gear ratio (more steps on each mm...

Must be the X axis then which uses belts :/ maybe that is the reason. have been looking rebuild that axis

Hi all.
A couple of years ago I built a large homemade CNC machine. :) It has served me well but one thing is not going as it should with it. I cant cut holes in the right shape. It has a quit...

Hi. I have the same problem on my router. When pushing the kress spindle hard (I guess it draws more current and therefore generate more electrical noise) it triggers the limit switches in MACH3.
...

Hmm hopefully someone is looking at my posts and can give me some advice :/

I found a possible solution that maybe someone can verify.

I can now (to late) see that my resolution with the setup...

Har almost put my whole CNC machine together and rather then trying to calculate every thing in advance I built it and was set on needing to tweak it a little bit in the end to work out some of the...

I finally got the motors spinning :) happy days :) the CNC router is comming around nicely. However I have very high frequency squeeeeling noise from the steppers when they are holding the position...

Hmm sorry but I maybe used a little bit of Swenglish there :)

Contacts should be connectors.

For each axis there are 6 poles on the controller cirquit board. A, a, COM, COM, b, B and the...

Hi

Im currently building a CNC router and have bought a HobbyCNC Pro 4 axis controller. I have started to build the controller box and had some good 5 pole contacts that I wanted to use. The...

BTW here is a picture of my design. At least the x and y axis. 172113

I have just started another CBC build and have bought some gear. Starting to look at the ball nut I realize that thy are different then other ball nuts I have used. The ones I'm used to have a flange...

Hi

Anyone know where I can find tool holder forks? Are building a robotic milling station and want to build a tool stand to be able to have automatic tool change.

I have found some forks on...

Hi

Are building a CNC milling cell based on a ABB IRB 6400 Robot and a water chilled 8,5 KW Spindle from ELTEsrl with toolchanger.

Have to build a mounting adapter to mount the spindle to the...

Hi ger21.

I came to realize something.

I had tested the code in simulationmode with no big problems. When my problem occure Mach3 continues to read the G-code. It doesn´t shut down the process....

I read your post #16 more closely and there may be some problems with the path reversing in the end and the beginning of each part. Which my amateur analys guesses is caused by the radius...

No it should be the demo version. i just downloaded it from Artsofts website. But the code is less then 1000 lines and the problem accours around line 790 and there is no odd comand there???!

Best...

I just tested the code but addedthe G40 comand after every part and a new G41 or G42 before every part. The run still freezes at the same line :( What the f__k can be wrong. I can´t see anything in...

Thnaks I will test this. Do you think that this could be the problem?

The radius compensation worked fine as I mentioned earlier but now a new problem have arised. I have added three more profiles to cut in the same code and the three first (the old one and the two...

Tested some minute ago and it worked perfect :D Thanks for the advices.

Would this be right if tool #1 in my tooltable have a diameter of 4 mm?

Here is the code

I have modified it as I think it should look

How does it work.
I tried the G41 and G42 comand btu it cutted something very unsimilar to what I was expecting. I changed all the G1 to G42 in my g-code and tested. is this wrong?

Hi
Does anyone know if Mach3 has a radius compensation function or do I have to do this with a CAM program?

I´m trying to cut a wing profil in 2D from a dxf file.

Here comes some new pics.

Both motors in place. Soon we will be able to spinn the Y and X axis. hehe Finaly some progress!!!

Hi Here are some new pics of the progress. We have temporary welded the bearing mounts in place to be able to see how it fits.

One other thing. Is there no interest in this build from anyone....

Now the leadscrews have arrived from the guy who have work the ends of them and I testfitted them today to see how they will be mounted.

Here are some pics and also a link to a movie of me moving...

plates for fastening the bearings and motors are being lasercut now and I have recieved all the ballscrews. The are beeing adjusted in the ends now and will be delivered to me tomorrow. I have also...

Thanks Rob

I have roughly tuned the cards but will do some more fine tuning this week. I have also recieved all the pulleys and the bearings.

I have caded up some mounting plates so that the...

Have tuned the cards now and have som equestions. The motor will turn exactly 1 turn if I move it 8000 steps in the Rutextune program. Does this mean that the encoders are 8000 steps per revolution?...
