Re: New Rotary Axis Build

Managed to get some cutting done for some examples of what I can do.

Here is a short video of me cutting some flames in some 60mm diameter pipe. Wall thickness is 4mm.

And here are some pics as well.

Re: New Rotary Axis Build

Decided to leave the cutting side set as it is and came up with an idea (which you all more experienced guys would already know) I drew a drawing with the letters '"MWS" and 2 lines either side. I programmed the drawing to start from the outer edge of the pipe/tube and it turned out ok. Ra...

Re: New Rotary Axis Build

Just as you suspected Jester...the letters L and R do go backwards. See the pic. Been trying to get it right with the dir on the output etc but still no luck. I have sent an email to my cnc guy and asked him. Now just waiting for a reply. Will keep you posted. Mtw fdu. UPDATED POST Spent another 2 h...

Re: New Rotary Axis Build

Thanks guys. Will check the dir in ports and pins and recheck it. Thank you again acourtjester for your help. You have been a "BIG" help. I have a few other things to do over the next few days and give myself a rest from this. It has been mentally draining as I have been working on this fo...

Re: New Rotary Axis Build

I GOT IT!!!!! Found out myself that the speed was set too fast. It was set to 1000mm per minute but I changed it to 800mm per minute and it cut well. I also had to change the g-code as well. When I posted the drawing it came up with axis both x and y. I had to change every y to an A and then it cut ...

Re: New Rotary Axis Build

Thank you Jester. I understand that now. Mtw fdu. UPDATED TO POST I did all that and it took some time to get it sorted. Now another day and another issue. This is regarding direction. Some of the g-code moves forward and backwards when it is supposed to and some do not. All the simple ones like a c...

Re: New Rotary Axis Build

Thank you Jester. In the video I posted the tube/pipe is 60mm diameter with the length being 188.4956mm. The spindle is set to 10 steps per mm. When I do 100mm diameter tube/pipe the length of that is 314.2875mm. What is the calculation to get the steps per mm please and other sized tube pipe as wel...

Re: New Rotary Axis Build

I GOT IT!!!!! Well I got the g-code to turn the material and simulate a very short cut to act as though I am cutting the end of the material off. I had to play with it using various processors and ended up also adjusting the g-code after it was posted with a few of the measurements changed and/or de...

Re: New Rotary Axis Build

Thank you Jester. At the moment I am cutting 60mm diameter tube with a wall thickness of 4mm. I usually use 1000mm/min for 3 - 6mm "flat" sheet. I will stick to this for now. Having said that most/all of the tube I will be cutting will not be under 3mm in thickness. I will probably only cu...

Re: New Rotary Axis Build

Finally found my profile I got from my cnc guy. I put the .xml file in the wrong spot. After I found it and loaded it up everything that needed to be done had been done. Just a quick question please...What are the recommended federate and spindle speeds? Or should my profile already work that out? T...

Re: New Rotary Axis Build

Jester...Yes I did. I ended trying to cut some letters into a tube but it kept diving into the material. I then cut a square which I created in my normal "flat" profile and loaded it in the rotary profile and it cut well and did what it was suppose to do. See the pic. I know the square cut...

Re: New Rotary Axis Build

Sorry Jester I have got a separate profile for my rotary axis. I did do a sample but it did not display at all in Mach 3. Just got a post processor from Bobcad this morning (Australian time). Will use that and check to see if it displays ok in Mach 3.

Will keep you updated. Cheers.

Re: New Rotary Axis Build

Had some spare time to work on my rotary axis. Have done everything to setup Mach 3 apart from how do I make sure A is set as rotary? Do I just make sure it turns when it is suppose to or is it more complicated than that. I am going by what my cnc guy sent me a few posts up (Number 3 on the list). I...

Re: New Rotary Axis Build

Finally...I got my profile from my cnc guy.

Will do all the change overs and setting the ports and pins and motor tuning over the next few days and will post up some results after testing. And some more video as well.

Re: New Rotary Axis Build

Did a little bit more to my rotary axis.

Cut and installed a chain tensioner to the top and bottom shafts as well as mounted my earth cable (braided copper) to the chuck shaft for earthing it together.

Still have not yet heard from my cnc guy.

Re: New Rotary Axis Build

Thanks guys for your input. I decided to use my existing y motor axis to run my rotary because it was the cheapest and easiest way to go. I cannot get in touch with my cnc guy as he is not answering any emails or telephone messages so it looks I am going to have to wait until he decides to do the ri...

Re: New Rotary Axis Build

Thanks motoguy. This is what my cnc guy sent me about 2 months ago. 1) Switch the Y motor output pins to the A axis output pins 2) insert the Y motor tuning values into the A axis 3) Make sure that A is set as rotary 4) change the A steps per so that you get an acurate angular movement - IE 360 degr...

Jester...or anyone else that may know... Somewhere in Mach 3 there is a chart to use to convert steps per mm/inches from flat plate to round tube. I cannot find it so can someone please point me in the right direction? Thanks in advance. I am still having trouble with my cnc guy not sending me my pr...

Still waiting to get my "profile" from my cnc guy. Can't do anything until I have this.

He is now starting to annoy me with false promises of sending it to me. :x :x :x

Corfabrication. Yes that was a lot of machining which had to be done. I took my time with it so I didn't have to start with a new piece. Ogre. Thanks for your info. Capstone. That "ka-chunk" is backlash. I still need to make a tensioner for the chain. Have been waiting for my cnc guy with ...

Re: New Rotary Axis Build

1 thing I forgot to ask is how do you earth the rotary axis? Also how do you earth the material being cut? Thinking that the earth lead from the plasma machine will get wrapped up if continuously going round and round.

Thanks in advance.
